When approved by the Secretary, through the Chief, Traffic Engineering and Operations Division, these signs shall also be regarded as official signs.
(b) Existing nonstandard signs. Official signs must replace existing signs of nonstandard design or application as rapidly as is economically feasible.
(c) Unacceptable variations. Variations in the proportion of symbols, stroke width and height of letters, width of borders or layout of word or symbol messages will be sufficient cause for the Secretary to order the removal or replacement of a sign, but will not be a defense in prosecution for violation of any mandatory traffic control provided by the sign.
§ 212.102. Sign manufacturers.
Only signs manufactured by the Department or a Department-approved sign manufacturer shall be used on any highway. Commercial or municipal sign manufacturers who wish to obtain Department approval to manufacture signs shall request an application from the Bureau of Highway Safety and Traffic Engineering.
§ 212.103. Sign size.
Signs smaller than the minimum size or larger than the largest size specified on the sign standards in the Pennsylvania Handbook of Approved Signs (Department Publication 236M) are not permitted without written approval from the Department.
§ 212.104. Retroreflectorization.
Retroreflective sheeting or other approved retroreflective materials must be used on all signs that do not have sign illumination, unless the sign standard as included in the Pennsylvania Handbook of Approved Signs (Department Publication 236M) indicates that the sign does not need to be retroreflective. Type III or higher type retroreflective sheeting is encouraged to improve nighttime visibility of signs, especially for older drivers.
§ 212.105. Sign posts and mountings.
Unless physically protected by guide rail or a barrier, or installed beyond the clear zone as defined in the Departments Design Manual, Part 2 (Department Publication 13M), all sign posts must be of a Department-approved breakaway design as listed in the Approved Construction Materials (Department Publication 35), and in accordance with the Signing and Marking Standards (Department Publication 111M).
§ 212.106. Additional warrants for Stop Signs (R1-1) and Yield Signs (R1-2).
(a) Through highways. The Department and local authorities may designate highways as through highways to permit more continuous movement and less delay to the major flow of traffic.
(1) Stop Signs (R1-1) or Yield Signs (R1-2) may be installed at all approaches to the through highway to provide preferential right-of-way at intersections.
(2) The designation of a highway as a through highway does not prevent modification of the right-of-way assignment at intersections of the through highway.
(3) The justification for the modification at a particular intersection will be based on the warrants in the MUTCD and the additional warrants in subsection (b), (c) or (d).
(b) Stop Signs (R1-1) at intersections. In addition to the warrants for stop signs in the MUTCD (relating to stop sign applications), a Stop Sign (R1-1) may be installed on a channelized right-turn roadway at a signalized intersection where the traffic-control signals are not readily visible, and the right-turn roadway does not have separate signals, and a Yield Sign (R1-2) is not appropriate.
(c) Multiway stop applications. In addition to the criteria and options warranting multiway stop applications in the MUTCD, the following apply:
(1) The five or more reported crashes in a 12-month period for Warrant B may include both reportable crashes, and nonreportable crashes that are documented in the police files, that occurred during a 12-month period during the most recent 3 years of available crash data.
(2) Multiway stop applications may not be used because of limited available corner sight distance unless there is no practical method of improving the sight distance or reducing the speed limit to satisfy the minimum corner sight distance values.
(d) Stop and yield control at locations other than intersections.
(1) One-lane bridges and underpasses. Stop Signs (R1-1) are warranted in advance of a one-lane bridge or underpass when roadway geometry is such that drivers cannot see an approaching vehicle in sufficient time for both vehicles to stop prior to entering the bridge or underpass. If sight distance is not a problem, a Yield Sign (R1-2) with the supplemental To Oncoming Traffic Sign (R1-2a) may be installed at both ends of a one-lane bridge or underpass.
(2) Crossings. Stop Signs (R1-1) may be installed on highways on a temporary basis at officially designated crossings such as construction haul roads. These Stop Signs (R1-1) should only be visible and in effect during the time periods the crossing is being used and should be supplemented with a flashing red light for added visibility.
(3) Private roads and driveways. Stop Signs (R1-1) or Yield Signs (R1-2) may be installed to control traffic exiting from a private road or driveway onto a highway or to control traffic on the highway at a private road or driveway if the warrants applied at highway intersections are satisfied.
(4) Truck pulloffs on hazardous grades. A Stop Sign (R1-1) may be installed within an officially designated truck pull-off area in advance of a hazardous grade indicating the location that trucks are to stop within the pulloff.
(5) Temporary traffic control. Stop Signs (R1-1) may be installed at both ends of short one-lane construction, maintenance or utility operation to provide self-regulating traffic control providing the one-lane section excluding the tapers is less than 250 feet, the ADT is less than 1,500, and the sight distance is sufficient.
§ 212.107. Except Right Turn Sign (R1-1-1).
When a major traffic movement at an intersection is a right turn, the Except Right Turn Sign (R1-1-1) may be placed below the Stop Sign (R1-1) on that approach to minimize the total delay at the intersection. When this sign is used, Stop Signs (R1-1) are required on all other intersection approaches except for the approach with a corresponding left-turn movement.
§ 212.108. Speed limits.
(a) General. This section applies to maximum speed limits established according to 75 Pa.C.S. § § 3362 and 3363 (relating to maximum speed limits; and alteration of maximum limits). Engineering and traffic studies are not required for statutory speed limits, but documentation should be on file for urban districts and residence districts to show that the requirements defined in the Vehicle Code are satisfied.
(b) Engineering and traffic studies. Speed limits established in accordance with 75 Pa.C.S. § 3363 may be established in multiples of 5 miles per hour up to the maximum lawful speed. The speed limit should be within 5 miles per hour of the average 85th percentile speed or the safe-running speed on the section of highway, except the speed limit may be reduced up to 10 miles per hour below either of these values if one or more of the following conditions are satisfied:
(1) A major portion of the highway has insufficient stopping sight distance if traveling at the 85th percentile speed or the safe-running speed.
(2) The available corner sight distance on side roads is less than the necessary stopping sight distance values for through vehicles.
(3) The majority of crashes are related to excessive speed and the crash rate during a minimum 12-month period is greater than the applicable rate in the most recent high-crash rate or high-crash severity rate table included in the appendix of Official Traffic-Control Devices (Department Publication 212). Crashes related to excessive speed include those crashes with causation factors of driving too fast for conditions, turning without clearance or failing to yield right-of-way.
(c) Variable speed limits. To improve safety, speed limits may be changed as a function of traffic speeds or densities, weather or roadway conditions or other factors.
(d) Special speed limits.
(1) Within a rest area or welcome center, a 25 mile per hour speed limit may be established without the need for an engineering and traffic study if pedestrians walk across the access roadways between the parking lot and the rest facilities.
(2) Within a toll plaza or a truck weight station, an appropriate speed limit may be established without an engineering and traffic study by the authorities in charge to enforce the safety of the operations or to protect the scales.
(e) Posting of speed limits. A Speed Limit Sign (R2-1) or variable speed limit sign showing the maximum speed limit shall be placed on the right side of the highway at the beginning of each numerical change in the speed limit, but an additional sign may also be installed on the left side of the highway. If the new speed limit begins at an intersection, the first sign should be installed within 200 feet beyond the intersection. The placement of this sign must satisfy both the requirement to post the beginning of the new speed limit and the requirement to post the end of the previous speed limit. Additional requirements for posting are as follows:
(1) Speed limits of 50 miles per hour or less shall be posted as follows:
(i) A Reduced Speed (
) Ahead Sign (R2-5), or a Speed Reduction Sign (W3-5), shall be placed on the right side of the highway 500 to 1,000 feet before the beginning of every speed reduction unless one of the following applies:
(A) The speed reduction is 10 miles per hour or less.
(B) The speed reduction begins at an intersection and all traffic entering the roadway with the speed reduction has to either stop at a Stop Sign (R1-1) or make a turn.
(C) The new speed limit is posted on variable speed limit signs.
(ii) Speed Limit Signs (R2-1) or a variable speed limit sign showing the maximum speed shall be placed on the right side of the highway at the beginning of the speed limit and at intervals not greater than 1/2 mile throughout the area with the speed limit.
(iii) The end of a speed limit is typically identified by the placement of a sign indicating a new speed limit, but the End Plaque (R2-10) may be placed above a Speed Limit Sign (R2-1) at the end of the zone if the appropriate speed limit is not known on the following section of roadway.
(2) On freeways, a Speed Limit Sign (R2-1) shall be installed after each interchange unless insufficient space exists for the signs.
§ 212.109. Bridge speed limits.
(a) Establishment. A bridge speed limit shall be established under 75 Pa.C.S. § 3365(a) (relating to special speed limitations) if an engineering investigation by a professional engineer establishes the need to reduce the vibration and impact of vehicles due to a structural condition of the bridge or elevated structure.
(b) Posting. An established bridge speed limit shall be posted similar to other speed limits in § 212.108(e) (relating to speed limits), except that a Bridge Sign (R12-1-2) must be mounted directly above each Speed Limit Sign (R2-1) and Reduced Speed (
) Ahead Sign (R2-5). The sign indicating the beginning of the bridge speed limit should be installed within 50 feet of the beginning of the structure. The end of the bridge or elevated structure must be the end of the bridge speed limit.
§ 212.110. Hazardous grade speed limits.
(a) Establishment. A hazardous grade speed limit may be established under 75 Pa.C.S. § 3365(c) (relating to special speed limitations) if an engineering and traffic study establishes the need for all vehicles or vehicles having a gross weight in excess of a designated weight to be limited to a maximum speed on a downgrade.
(1) The designated weight should be 26,000 pounds unless the engineering and traffic study determines that a different weight should be used.
(2) When a hazardous-grade speed limit is established, it should be consistent with the speed that similar vehicles can climb the hill or other Department-approved methodology, except that a hazardous-grade speed limit should not be greater than the lowest advisory speed or legal speed limit either on the hill or at the base of the hill.
(3) A hazardous-grade speed limit may be established when one or more of the following conditions exist:
(i) The length of grade exceeds the value set forth in the following table:
Length of Grade
Average Grade (percent) Condition A* Condition B** -3 20,000 -4 8,000 16,000 -5 5,000 10,000 -6 3,000 6,000 -7 2,000 4,000 -8 1,800 3,600 -10 1,500 3,000 -12 1,250 2,500 -15 1,000 2,000
* Condition A applies if vehicles are required to stop or reduce speed at or before the bottom of the hill or if there is an urbanized area at the base of the hill.
** Condition B pertains to all other locations.
(ii) A crash has occurred on the downgrade that can be attributed to the speed of a vehicle having a gross weight in excess of the designated weight.
(iii) A verified report has been received during the past 3 years of an operator losing control of a vehicle on the grade, and the vehicle is a type having a gross weight in excess of the designated weight.
(b) Posting. A hazardous grade speed limit shall be posted with traffic-control devices as follows:
(1) A Reduced Speed (
) Ahead Sign (R2-5), advising of the maximum hazardous grade speed limit, with a Truck Marker (M4-4), or other marker as applicable, mounted directly above the Reduced Speed (
) Ahead Sign (R2-5), shall be placed on the right side of the highway at a distance of 500 to 1,000 feet before the hazardous grade speed limit, except that this advance sign is not required if the hazardous grade speed limit begins at a vehicle pull-off where all applicable vehicles are required to stop.
(2) A Trucks Over (
) Lbs. Speed Sign (R2-2-1), or other sign as applicable, shall be erected at the beginning of the hazardous grade speed zone and at intervals not greater than 1/4 mile throughout the zone.
(3) A Trucks Over (
) Lbs. Speed Sign (R2-2-1), or other sign as applicable, with an End Sign (R2-10) mounted above the Trucks Over (
) Lbs. Speed Sign (R2-2-1) or other sign, shall be installed at the end of the hazardous grade speed limit.
§ 212.111. Turn restriction warrants.
A straight-through or turning movement may be restricted if the movement can be made at an alternate location, and if one or more of the following conditions are present:
(1) A review of vehicle crashes shows that ten crashes have occurred during the previous 3 years, or five crashes have occurred during any 12-month period in the previous 3 years that can be attributed to vehicles making or attempting to make the movement.
(2) When a capacity analysis or field review of the intersection indicates that turning or crossing vehicles are causing unreasonable delays or creating a potential crash situation for through vehicles.
(3) When a field review of the intersection indicates that significant conflicts occur between vehicles making or attempting to make a particular movement and other vehicular or pedestrian movements.
(4) When a field review of the intersection indicates that a turn or straight-through movement delays the platoon of vehicles through a progressive signal system.
(5) When a field review of the intersection indicates that the geometric design or the available corner sight distance does not adequately provide for the movement or the movement frequently cannot be safely executed.
§ 212.112. Signs to prohibit passing.
The No Passing Zone Pennant (W14-3) is the primary sign to identify the beginning of a no-passing zone on a two-lane highway and shall be installed on the left side of the road. The Do Not Pass Sign (R4-1) may be installed on the right side of the roadway to supplement the No Passing Zone Pennant Sign (W14-3). The Pass With Care Sign (R4-2) may be installed at the end of the no-passing zone. Warrants for no-passing zones are included in § 212.202 (relating to no-passing zones).
§ 212.113. One-way streets.
A one-way street may be established if the following conditions are satisfied:
(1) The traffic flow can be accommodated in both directions. Whenever possible, an adjacent parallel street should be used to form a one-way couplet.
(2) The street has a reasonable number of intersections for entrance to or exit from the one-way street or one-way system.
(3) The roadways at the terminal points of the one-way street provide satisfactory transitions to and from the two-way operation.
(4) There will be a reduction of intersection delays.
(5) Existing bus routes can be satisfactorily accommodated.
§ 212.114. Stopping, standing and parking restrictions.
(a) General. Stopping, standing or parking may be restricted along the curb or edge of a roadway when one or more of the following conditions exist:

(2) The street width is such that, if vehicles are parked along one or both curb faces or edges of the roadway, two vehicles cannot move abreast of one another in the same or the opposite direction without one yielding to allow the other vehicle to pass.
(3) A capacity analysis indicates that parking should be removed at all times or during certain hours to accommodate the traffic volume.
(4) At an intersection, the available corner sight distance for a driver on the minor road is less than the necessary minimum stopping sight distance value for the driver on a through roadway.
(5) An analysis of vehicle crashes indicates that at least three crashes during the previous 3-year period have been directly or indirectly attributed to one of the following primary causes:
(i) Vehicles parking on the roadway.
(ii) Vehicles entering or leaving the parked position.
(iii) Drivers or passengers getting out of parked vehicles on the street side.
(iv) Reduced sight distance due to the parked vehicles.
(6) The area is designated as an official bus stop or as a loading and unloading zone.
(7) The area is adjacent to or opposite of a fire station driveway or any other type driveway or intersection where turning maneuvers would be restricted if parking were present.
(8) The width of the shoulder is not sufficient to allow a vehicle or its load to park completely off the roadway.
(9) Along roadways having three or more lanes and speed limits of 40 miles per hour or above, parking may be restricted to allow vehicles to use the berm or shoulder as a clear recovery area.
(b) Angle parking. As defined in § 212.1 (relating to definitions), angle parking will only be authorized as follows:
(1) New angle parking may be established only along streets where the following criteria are satisfied:

(iii) Additional travel lanes are not required for the existing traffic volumes to achieve a satisfactory level of operation.
(iv) Parking stalls will be adequately marked and spaced.
(v) Pedestrian activity is minimal within the parking maneuver area.
(2) It is recommended that existing angle parking be eliminated if an analysis of vehicle crashes indicates that the parking-related crash rate within the area of existing angle parking is greater than the rate on similar portions of the same street or other streets within the same municipality which have parallel parking.
(c) Parking meters. When parking is permitted, local authorities may install parking meters and appropriate pavement markings to designate parking stalls. The hours of effectiveness of parking meters must be indicated either on the meter or within the dome of the meter, but official traffic signs shall be erected to indicate hours when parking is prohibited.
(d) Prohibition of kinds and classes. When parking is permitted, local authorities or the Department may prohibit certain kinds and classes of vehicles from parking for safety, capacity or environmental reasons. Official signs must indicate the prohibitions.
(e) Parking reserved for persons with disabilities. The Reserved Parking Penalties Sign (R7-8f) shall be installed below all Reserved Parking Signs (R7-8), as provided in 75 Pa.C.S. § 3354(d) (relating to handicapped persons and disabled veterans).

(5) Whenever signs required to implement the provisions of paragraph (3) become either obsolete or missing, they must be replaced with new official signs as rapidly as is feasible. The costs associated with the installation and replacement of the required signs for a particular location must be borne by the owner or person in control or possession of the property on which the signs are to be erected.
§ 212.116. No Turn on Red Sign (R10-11 sign series).
(a) Warrants for no-turn-on-red restrictions. The following warrants may be used in addition to the warrants for no-turn on red restrictions in the MUTCD (relating to traffic signal signs).
(1) A right turn on red, or left turn on red from a one-way highway to another one-way highway, may be prohibited from an intersection approach where an engineering and traffic study indicates that one or more of the following conditions exist:
(i) The available corner sight distance between a driver desiring to turn on red and an approaching vehicle on the cross street is less than the minimum shown on the following table:
Speed Limit or 85th
Minimum Sight Distance to Approaching Vehicle*
Std. Cross Street Approach Grade Values -9% -6% -3% 3% 6% 9% 25 152 173 165 158 147 143 140 30 197 227 215 205 200 184 179 35 247 287 271 257 237 229 222 40 301 354 333 315 289 278 269 45 360 427 400 378 344 331 320 50 424 507 474 446 405 388 375 55 493 593 553 520 469 450 433
* Measure sight distance from a location 10 feet before a marked pedestrian cross walk or, if none, 10 feet from the edge of the cross street roadway or curb line, where both the eye and the approaching vehicle are 3.5 feet high.
(ii) The intersection has more than four approaches or has restrictive geometry that is likely to cause vehicular conflicts which are not easily recognized by drivers.
(iii) The turning movement is allowed from more than one lane on a specific approach.
(iv) The vehicular turning movement would result in significant vehicular and pedestrian conflicts, such as locations where the crosswalk is designated as a school crossing or is used by large numbers of children, senior citizens or persons with physical disabilities. A no-turn-on-red restriction at these locations may only apply during the time periods that significant vehicular-pedestrian conflicts would occur, in accordance with paragraph (3).
(v) Opposing traffic has unusual movements, such as double left turns, which would not be expected by drivers turning on a red signal.
(vi) An analysis of vehicle crash data indicates that the turn-on-red movement has created an unsafe condition.
(2) Part-time or intermittent prohibition of the turn-on-red movement must be used at locations where a potential safety concern exists for only a portion of the day. These restrictions must be implemented by the use of one or more of the following:
(i) A Restricted Hours Panel (R10-20A) under the No Turn On Red Sign.
(ii) A supplemental message incorporated directly into the No Turn On Red Sign.
(iii) A sign designating the hours the restriction is effective.
(iv) A blank-out No-Turn-On-Red Sign.
(3) A part-time or intermittent prohibition of the turn-on-red movement may be used at an intersection approach where vehicles turning on red would cross an at-grade railroad crossing within 200 feet and the traffic signal controller is preempted during train movements during the time the signal controller is preempted in accordance with paragraph (2).
(b) Application. This section applies to signalized roadway and driveway intersections along all highways.
(c) Engineering and traffic studies. Engineering and traffic studies required by subsection (a)(1) shall be conducted by local authorities. The Department will be responsible for conducting the study at the following locations:
(1) At intersections where the traffic signal controller is preempted during train movements for a nearby crossing.
(2) At new or revised traffic signal installations when the traffic signal is designed by the Department.
(d) Department approval. Written approval of the Departments district executive shall be obtained prior to installation of a No Turn on Red Sign (R10-11 Series) at any intersection where the Department has issued the traffic signal permit.
§ 212.117. Weight, size and load restrictions.
(a) Weight restriction based on condition of bridge. Traffic on a bridge may be prohibited or restricted by weight of vehicle, number of vehicles, or kinds or classes of vehicles when an engineering evaluation conducted by a professional engineer establishes the need. Engineering evaluation of a bridge or bridge component may be based on structural analysis and rating computations, testing, engineering judgment or a combination thereof. Restriction is warranted when one or more of the following conditions are present:
(1) The safe load capacity of the bridge is exceeded by the load effect of any of the legal load configurations. The capacity and load effects are to be determined in accordance with the Bridge Safety Inspection Manual (Department Publication 238).
(2) Engineering judgment indicates that the condition or material of construction of one or more portions or components of a bridge is such that further use by heavy vehicles may damage the bridge because of severe impact, fatigue or other reasons.
(3) The bridge is damaged due to fire, a vehicle crash or environmental deterioration, and engineering judgment indicates that a vehicle weight restriction is necessary to ensure an adequate level of safety.
(b) Weight restriction based on condition of highway. Traffic on a highway may be prohibited or restricted by weight of vehicle, or kinds or classes of vehicles when warranted by an engineering evaluation. Engineering evaluation may be based on structural analysis, testing, engineering judgment or a combination thereof. A restriction is warranted when one or more of the following conditions are present:
(1) The highway pavement or shoulders have inadequate structural capacity or have been weakened due to deterioration, high traffic volumes or climatic condition, and may be seriously damaged unless a restriction is imposed.
(2) An engineering evaluation of previous similar climatic conditions on the highway or on similar highways indicates that vehicles over a certain weight should have been prohibited.
(c) Size restriction based on condition of bridge or highway. Traffic on a bridge or highway may be restricted by size of vehicle or kinds or classes of vehicles when, after an engineering evaluation, one or more of the following conditions are found to be present:
(1) A bridge has poor alignment, substandard horizontal or vertical clearance, or creates problems for vehicles with low ground clearance, or the restriction is otherwise necessary to protect the bridge from vehicle crashes or damage.
(2) A highway has inadequate turning radii, horizontal width or creates concerns for vehicles with low ground clearance at one or more locations.
(d) Weight and size restrictions based on traffic conditions. Traffic on a highway or bridge may be prohibited or restricted by weight or size of vehicle, or kinds or classes of vehicles when, an engineering evaluation of the horizontal and vertical alignment, prevailing traffic speeds, compatibility of the various types of traffic, history of vehicle crashes or vehicular characteristics, indicates that the movement of certain vehicles constitutes a safety hazard. Restrictions may include weight; height, width or length of vehicles or their loads; types of cargo; speed or gearing; stopping requirements; specified travel lanes; and hours of operation.
(e) Erection of signs. Appropriate signs shall be erected within 25 feet of each end of a restricted portion of a highway or bridge whenever vehicles are prohibited under subsection (a), (b), (c) or (d). In the case of a restriction on a highway or bridge which does not begin or end at an intersection with an unrestricted highway, an advance information sign shall also be erected at the intersection nearest each end of the restricted highway or bridge to allow drivers to avoid the restricted highway or bridge.
(f) Alternate routes. An alternate route shall be established whenever vehicles are prohibited under subsection (a) or (b) on either a numbered traffic route or a State-designated highway on the National Highway System, as established by the Federal Highway Administration, when the following apply:
(1) A reasonable alternate route exists which is not readily perceived by drivers.
(2) The alternate route can legally, safely, structurally and physically accommodate the weight and size of vehicles and their loads that are being detoured.
(3) Five or more vehicles per day are estimated to be prohibited from using the original route.
§ 212.118. Street name signs.
For street name signs, white lettering on a green background is recommended, but local authorities may use white lettering on blue or brown background, or black lettering on white background, provided the same colors are used systematically throughout the municipality. To improve sign legibility, upper and lower case lettering is recommended.
§ 212.119. Signing of named highways.
§ 212.120. General motorist service signs.
The application of general motorist service signs shall be in accordance with the Departments Statewide policy and the Signing and Marking Standards (Department Publication 111M), and will be limited to expressways and freeways, except:

§ 212.121. Specific service signs.
(a) The Department may enter into an agreement with a private agency to administer a program for specific service signs for gas, food, lodging, camping and attractions. Specific service signs may only be installed on freeways, except small trailblazer signs shall be installed on conventional highways when it is necessary to guide motorists to the physical site of the specific service. If a trailblazer is required on a local roadway to direct motorists to a specific business, and the local authority refuses to allow the trailblazer on its local highway, specific service signs may not be provided for that business.
§ 212.122. Recreational and cultural interest area signs.
Recreational and Cultural Interest Area Signs, as described in Chapter 2H of the MUTCD, that is, relating to the RG, RM, RA, RL, RW and RS Series signs, will be authorized for use within any State park, State forest picnic area, Federal recreation area, National forest or public park.
§ 212.123. Tourist-oriented directional signs.
Tourist-Oriented Directional Signs (D7-4) must be of the size and type specified in the Departments Handbook of Official Signs (PennDOT Publication 236M) or as specified in an agreement with the Department, instead of the design included in Chapter 2G of the MUTCD (relating to tourist-oriented directional signs). The Department may enter into an agreement with an outside entity to administer a program for tourist-oriented directional signs.
Subchapter C. MARKINGS
212.201. Pavement marking standards.
212.202. No-passing zones.
§ 212.201. Pavement marking standards.
The Signing and Marking Standards (Department Publication 111M) contains additional design details for pavement markings. Pavement markings for lane drops, expressways, freeways, on-ramps and off-ramps, and all pavement marking words and symbols must conform to the Signing and Marking Standards.
§ 212.202. No-passing zones.
(a) Additional warrants on two-lane, two-way highways. In addition to the sight distance warrant in Section 3B.02 of the MUTCD (relating to no-passing zone pavement marking and warrants), no-passing zones may be established at the following locations on two-lane, two-way highways with center line pavement markings:
(1) In advance of a divided highway or an obstruction such as a bridge support pillar, a channelizing island or a safety zone, which separates the two lanes of traffic.
(2) On or within, and in advance of any bridge, tunnel or underpass designated as a narrow bridge or underpass in accordance with § 212.1 (relating to definitions).
(3) In advance of a Stop Sign (R1-1), Yield Sign (R1-2) or traffic signal.
(4) On the approach to an intersection where passing may be undesirable due to the high number of crossing or turning movements.
(5) Within a school zone.
(6) In areas where an analysis of vehicle crashes shows an unusually high number of passing-related crashes.
(7) In areas where the roadside development includes many driveways and intersections where passing would create frequent potential conflicts.
(8) At locations where the roadway width is very restrictive, shoulders are nonexistent or in poor condition, the roadway cross-section has an excessive crown, or obstacles are close to the roadway.
(9) In areas where traffic volumes are very heavy and there would be very limited opportunities for motorists to pass other vehicles.
(10) At locations where a passing zone would otherwise be less than 600 feet in length.
(11) At locations where engineering judgment indicates that allowing passing is undesirable because a better passing area exists farther ahead.
(b) Minimum advance distance. No passing zones established according to subsection (a)(1)(5) must precede the location by the minimum distance noted in the following table:
Speed Limit or 85th
35 or less 300 40 350 45 400 50 450 55 500
§ 212.203. Delineation.
The 4-foot mounting height for delineators specified in the MUTCD (relating to delineator placement and spacing) is not applicable for guide rail and barrier-mounted delineators. In addition, post-mounted delineators may be 4 feet above the ground instead of 4 feet above the near edge of pavement as specified in the MUTCD.
Subchapter D. HIGHWAY TRAFFIC SIGNALS
212.302. Traffic-control signals.
212.303. Pedestrian-control signals.
§ 212.301. Purpose.
This subchapter sets forth additional guidance and criteria relating to the design, application and operation of traffic-control signals within this Commonwealth. The Traffic StandardsSignals TC-8800 Series (Department Publication 148M) and the Traffic Signal Design Handbook (Department Publication 149M) contain additional design details, specifications, checklists and forms.
§ 212.302. Traffic-control signals.
(a) Flashing operation of traffic-control signals. During flashing operation, a minimum of two vehicular signal heads on each approach must be flashed for the through movement. Any other signal heads may be blanked out.
(b) Warrants. In addition to the criteria in the MUTCD, the following applies:
(1) Traffic volumes. The traffic volume for channelized right-turn movements may not be included in any warrant analysis.
(2) Vehicle crashes. The five or more reported crashes within a 12-month period for Warrant 7 in the MUTCD (relating to Warrant 7, crash experience) may include both reportable crashes, and nonreportable crashes that are documented in the police files, that occurred within a 12-month period during the most recent 3 years of available crash data.
(3) Warrant 9, ADT volume warrant.
(i) An ADT volume warrant is added as Warrant 9 and may be used in addition to the eight warrants contained in Sections 4C.02 through 4C.09 of the MUTCD (relating to Warrants 1 through 8). This warrant must apply at a proposed intersection, an intersection revised by a highway construction project, or at the driveway of a proposed commercial or residential development where vehicle counts cannot be taken. If a traffic-control signal is installed under this warrant, a traffic count must be taken within 6 months of the opening of a development or within 2 years of the opening of a highway. If the traffic volumes do not satisfy this warrant, or one or more of the other eight warrants, consideration should be given to removing the traffic-control signal and replacing it with appropriate alternative traffic-control devices, if any are needed.
(ii) This warrant is satisfied when the estimated ADT volumes on the major street and on the higher volume minor street or driveway approach to the intersection, when projected using an accepted procedure such as put forth in the Trip Generation Manual published by the Institute of Transportation Engineers, equals or exceeds the values in either Condition A or Condition B:
Condition AADT Volume Warrant Number of Lanes for Moving

* Based on the volume projected to be present within 6 months of the opening of the development or within 2 years of the opening of the highway.
** May be used if the 85th percentile speed of the major street traffic exceeds 40 miles per hour or the intersection lies within the built-up area of an isolated community having a population of less than 10,000.
§ 212.303. Pedestrian-control signals.
Pedestrian-control signals provide special types of traffic signal indications for the exclusive purpose of controlling pedestrian traffic. These indications consist of the illuminated symbols of a walking person (symbolizing WALK) and an upraised hand (symbolizing DONT WALK) or the illuminated words WALK and DONT WALK.
(1) New pedestrian-control signals must use symbolized messages.
(2) Signals using word messages may be retained for their useful service life.

§ 212.401. General.
This subchapter supplements the criteria in the MUTCD, and applies to highway construction, maintenance operations and utility work or incident management, either on a highway or so close to a highway that workers, equipment or materials encroach on the highway. Compliance with this subchapter does not relieve the contractor or others of their general responsibility for the protection of the public and the employees in work zones.
§ 212.402. Exempt work.
(a) General. The following types of work are exempt from the requirements contained in this chapter and in the MUTCD:
(1) Snow plowing and other snow or ice control operations.
(2) Refuse collection, trash collection, leaf pick-up, street cleaning, municipal street sweeping and residential lawn care.
(3) Operations which do not involve construction, maintenance operations or utility work, such as mail, newspaper, home fuel or other local deliveries.
(4) Studies or inspections of highway or utility features which may be completed without blocking any part of a travel lane.
(5) Construction, maintenance operations or utility work in areas outside the highway right-of-way; except when the work is so close to the highway that workers, equipment or materials encroach on the highway.
(6) Construction, maintenance operations or utility work where all workers, equipment or materials are behind a guide rail, more than 2 feet behind a curb or 15 feet or more from the edge of a roadway.
(7) Mowing operations on roads with less than 10,000 vehicles per day and where equipment does not encroach on the roadway.
(8) Traffic data collection.
(b) Safety considerations. While the types of work in subsection (a) are exempt from the specific traffic-control guidelines of this subchapter, they must be accomplished in a manner that will provide an adequate degree of safety for the workers and the public.
§ 212.403. Temporary traffic-control plans.
Plans for construction projects must either reference or include a temporary traffic-control (TTC) plan, which must consist of one of the following:
(1) A reference to a specific figure either in the MUTCD or in the Work Zone Traffic Control Guidelines (Department Publication 213) that properly depicts actual site conditions.
(2) A copy of a specific figure either in the MUTCD or the Work Zone Traffic Control Guidelines (Department Publication 213) which has been modified to depict actual site conditions and the necessary traffic-control requirements for the specific project.
§ 212.404. Sign supports.
(a) Post-mounted signs. Post-mounted signs or signs on fixed supports shall be installed in accordance with the Signing and Marking Standards (Department Publication 111M).
(1) Post-mounted sign installations must be of a breakaway or yielding design unless they are adequately placed behind guide rail or median barrier.
(2) Signs may not be mounted on existing utility poles or other structures unless the owner grants written permission and the signs can be properly positioned to convey their messages effectively.
§ 212.405. Regulatory speed limits.
(a) General. Regulatory speed limits in temporary traffic-control zones and in the area in advance of a work zone where traffic queues are anticipated may be established as follows:
(1) A regulatory speed limit up to 10 miles per hour below the normal speed limit may be established without an engineering and traffic study, provided the reduced regulatory speed limit is at least 25 miles per hour. Regulatory speed limits less than 25 miles per hour or more than 10 miles per hour below the normal speed limit require an engineering and traffic study and the prior approval of the Department for State-designated highways and approval of local authorities for local highways. To qualify for an additional speed limit reduction, the engineering and traffic study must indicate that traffic queues, erratic maneuvers, high vehicle crash rates or undesirable working conditions exist on the project or have existed on similar projects.
(2) Regulatory speed limits for temporary traffic control must be signed with either Speed Limit Signs (R2-1), Work Area Speed Limit Signs (R2-2-2) or variable speed limit signs. For speed limits that are 50 miles per hour or less, the signs must be spaced not greater than 1/2 mile apart throughout the limits of the reduced speed limit zone. Conflicting regulatory or warning signs must be removed, covered, folded or turned so that they are not readable or identifiable by oncoming traffic whenever the reduced regulatory speed limit is in effect.
(3) A Speed Limit Sign (R2-1) showing the speed limit on the section of highway immediately after the work zone must be positioned at the end of the reduced regulatory speed limit, except an R2-1 sign is not necessary if a Work Area Speed Limit Sign (R2-2-2) is used and an End Road Work Sign (G20-2) or End Work Area Sign (G20-3) is in place at the end of the regulatory speed limit.
(b) Variable speed limits. In an effort to avoid unnecessary speed restrictions, variable speed limits are encouraged in lieu of static signs. These speed limits may be remotely controlled, either manually or by a computer using hardware and software to monitor functions such as traffic speeds, volumes, densities and queues.
§ 212.406. Channelizing devices.
(a) Device consistency. Channelizing devices used to form a particular taper or a particular longitudinal line of devices must all be of a single type. For example, cones, drums, barricades and vertical panels may not be intermixed within the same taper or line, but the type of device being used in a taper may differ from the type of device being used in a longitudinal section.
(b) Cones. Cones may only be used as a channelizing device for operations where work is in active progress. The minimum height of cones is 28 inches except cones that are 18 inches high may be used to protect new pavement markings.
§ 212.407. Markings.
When lane line and center line pavement markings on more than 250 linear feet of highway are covered or destroyed by construction, maintenance, utility, permit or other work, they must be replaced, before ending work each day, with standard pavement markings, or with temporary pavement markings as included in the MUTCD.
§ 212.408. Impact attenuators.
§ 212.409. Travel lane rumble strips.
Temporary bituminous rumble strips may be used in the travel lanes to provide an audible warning to alert drivers of a potentially dangerous situation including a median crossover, lane reduction and congested area. Recommended rumble strip designs are available from the Bureau of Highway Safety and Traffic Engineering. When used, the rumble strip patterns must extend onto the shoulder whenever possible to discourage drivers from making erratic maneuvers in an attempt to bypass or avoid the rumble patterns.
§ 212.410. Delineators.
§ 212.411. Flaggers.
(a) Helmet. In addition to the requirements of the MUTCD, flaggers shall wear a protective helmet.
§ 212.412. Flagger signaling devices.
§ 212.413. Portable traffic-control signals.
Portable traffic-control signals may be used to control one-lane, two-way traffic. They may also be used for other special applications such as a highway or street intersection with a temporary haul road or equipment crossing. The design and application of portable traffic-control signals must conform with the applicable requirements of the Departments certificate of approval issued to the manufacturer for portable traffic-control signals, and with any special requirements defined in the TTC Plan. For these applications, it may be desirable to use traffic-actuated or manual control to compensate for unbalanced traffic flows.
§ 212.414. Emergency work.
(a) General. Emergency work may be initiated without prior compliance with the traffic-control provisions specified by this subchapter, provided the foreman or lead worker implements all available safety measures, and the traffic control is brought into compliance with this subchapter as soon as possible. The foreman or lead worker may use flares as attention-getting and warning devices.
(b) Utility work. Emergency repair for utility work may be initiated under this section or repair to a utility facility undertaken under Chapter 459 (relating to occupancy of highways by utilities) to repair damage resulting from a vehicle crash or collision with the facility, a failed component or storm damage. Utility service connections or disconnections unrelated to a vehicle crash, a failed component, or storm damage must otherwise comply with this subchapter.
(c) Expediting emergency work. Emergency work may be completed without installation of work zone traffic-control devices required by this subchapter, if one of the following conditions is met:
(1) Review of the condition indicates that the emergency work can be completed in less time than it would take to install the temporary traffic-control devices, and the work or condition would not create a significant potential hazard.
(2) Temporary traffic control has been set up and it is found that additional traffic-control devices are desirable, but that it would take longer to obtain and install additional traffic-control devices than it would to complete the work.
§ 212.415. Type D Arrow Panels.
§ 212.416. Shadow vehicles.
§ 212.417. Flashing warning lights.
§ 212.418. Good management principles.
Agencies administering highway construction, utility work and maintenance operations shall mandate the application of the following good management principles:
(1) Keep the temporary traffic-control zones as short as practical to avoid long stretches with no work activity.
(2) Minimize lane restrictions.
§ 212.419. Special controls in work zones.
(a) General. Special signing required in 75 Pa.C.S. § § 3326, 3365, 4309, 6123 and 6123.1 will be in addition to the traffic-control devices required by the MUTCD and shall be installed in accordance with this section.
(b) Application. Signing under this section is discretionary in the following work zones:
(1) Short duration work, where the operation will be completed in less than 1 hour.
(2) Mobile operations, where the work moves intermittently or continuously.
(3) Stationary work where the daily duration of the construction, maintenance or utility operation is less than 12 hours and all traffic-control devices are removed from the highway at the completion of the daily operation, including all advance warning signs.
(4) Work along highways other than expressways or freeways where the normal speed limit is 45 miles per hour or less.
(5) Work in response to emergency work or conditions such as a major storm.
(c) Work ZoneTurn on Headlights Sign (R22-1). The Work ZoneTurn on Headlights Sign (R22-1) shall be erected as the first sign on each primary approach to the work zone, generally at a distance of 250 to 1,000 feet prior to the first warning sign. On high-speed roadways including all expressways and freeways, the larger advance distances should be used. If work begins at or near a border to this Commonwealth, the R22-1 signs should be installed within this Commonwealth.
(d) Active Work Zone When Flashing Sign (W21-19). The Active Work Zone When Flashing Sign (W21-19) shall be erected as close as practical to the beginning of the active work zone.
(1) The sign should not be erected within a transition or at a location where workers are put at risk when they may need to turn the light on and off.
(2) When a construction, maintenance or utility project has more than one active work zone and the active work zones are separated by a distance of more than 1 mile, signs for each active work zone shall be erected.
(3) The W21-19 signs shall be installed on temporary sign posts or on Type III barricades, and a white Type B high-intensity flashing light must be attached to the upper portion of each W21-19 sign. The light shall be activated only when workers are present, and deactivated when workers are not anticipated during the next 60 minutes.
(e) End Active Work Zone Sign (W21-20). The End Active Work Zone Sign (W21-20) shall be erected immediately at the end of each active work zone, except this sign is not necessary if either the End Road Work Sign (G20-2a) or the End Work Area Sign (G20-3) is installed at the end of the active work zone.
(f) Work zones on expressways or freeways. When the work zone is on an expressway or freeway, appropriate signs and lights identified in subsections (c), (d) and (e) at on-ramp approaches to the work zone shall be installed.
(g) Portable changeable message sign. A portable changeable message sign (PCMS) may be used in lieu of the R22-1, W21-19 or W21-20 signs.
(h) Speed display sign. In Interstate highway work zones with a project cost exceeding $300,000, a speed display sign shall be installed on each mainline approach to the work zone to inform motorists of their speed.
(1) The speed display sign must display the motorists speed in miles per hour in numerals at least 18 inches in height.
(2) As an alternative, a portable changeable message sign (PCMS) may be equipped with radar and programmed to display vehicles speeds.
(3) PCMSs may also flash appropriate messages such as YOU ARE SPEEDING or SLOW DOWN. The signs shall be placed 1/2 to 1 mile in advance of the physical work zone.
