A mobile home, modular housing unit or modular housing undercarriage that does not exceed 80 feet in body length, 14 feet in width—except as authorized in paragraph (3)—and 14 feet, 6 inches, in height may be transported upon the highway subject to the following requirements:

   (1)  The towing hitch mechanism of a modular housing undercarriage or mobile home shall be equipped with two antisway devices whenever the total width exceeds 13 feet, unless operating on a highway section having a posted speed below 40 miles per hour.
