Governor Taft asked the Ohio Turnpike Commission to work with ODOT and the OSHP to formulate a plan to encourage truck traffic to use the turnpike instead of parallel highways, improving the safety of those other roadways. The three organizations created a plan with three points. The truck speed limit was increased from for consistency with the automobile limits. Enforcement of truck weight and speed limits on parallel highways was increased, and truck toll rates were lowered in a trial. The speed limit increase took effect on September 8, 2004.
