Oklahoma Truck Speed Limit
No split. Trucks run the same posted limit as cars. Rural interstates are 75 (47 O.S. 11-801), and six rural turnpike segments now post 80, about 104 miles total. Urban interstates and other freeways sit at 70. The Turnpike Authority can set a separate truck speed on the pikes, but the posted 80 currently applies to everyone.
