      RELATES TO: KRS 186.050, 186.655, 189.222, 23 C.F.R. Part 658, 49 U.S.C. 31111

      STATUTORY AUTHORITY: KRS 189.222(1), (9), 23 C.F.R. Part 658

NECESSITY, FUNCTION, AND CONFORMITY: KRS 189.222 authorizes the Secretary of Transportation to establish reasonable size limits for motor vehicles using the State Primary Road System, which includes the roads maintained by the Department of Highways. 23 C.F.R. 658.19 requires that vehicles with increased dimensions transporting household goods and truck tractors towing only one (1) semitrailer not exceeding twenty-eight (28) feet (8.53 meters) in length be provided statewide access unless a route is specifically excluded for safety reasons. This administrative regulation establishes the motor vehicle and combination vehicle dimensions for all classes of highways in Kentucky. 23 C.F.R. Part 658 sets forth the highways available for use by vehicles with increased dimensions. This administrative regulation includes these highways as well as others which have been constructed to accommodate the motor vehicles with increased dimensions. In addition, 23 C.F.R. 658.19 requires each state to allow the increased dimension vehicles to operate within one (1) driving mile (1.61 kilometers) of the designated highways. On state-maintained highways in Kentucky, the increased dimension vehicles are allowed to operate within five (5) driving miles (8.05 kilometers) of a designated highway unless the designated highway is an interstate or a parkway in which instance the increased dimension vehicles are allowed to operate within fifteen (15) miles (24.14 kilometers) of the interstate or parkway exit. The bus dimension limits are established in 603 KAR 5:071.
