Veh Cd-speed Limits-70 Mph

Amends the Illinois Vehicle Code. Provides that outside the counties of Cook, DuPage, Kane, Lake, McHenry, and Will, the maximum speed limit outside an urban district for any vehicle is (1) 70 miles per hour on any interstate highway; (2) 65 miles per hour for all or part of highways that are designated by the Department of Transportation, have at least 4 lanes of traffic, and have a separation between the roadways moving in opposite directions; and (3) 55 miles per hour for all other highways, roads, and streets. Permits the Department of Transportation and Toll Highway Authority to alter speed limits up to the new maximum speed limit (rather than up to 65 miles per hour).
