      603 KAR 5:070. Motor vehicle dimension

limits.

 

      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.
