Operating Hours, Restricted Travel, and Holiday Restrictions
Oversize loads can move during daylight hours only (one-half hour before sunrise to one-half hour after sunset seven days a week). Only overweight vehicles can have continuous travel but must be requested when ordering the permit.
Oversize load movements are not allowed on the Interstate system through Cleveland, Oklahoma, and Tulsa counties between 7:00 a.m. to 9:00 a.m. and 3:30 p.m. – 6:30 p.m. Monday through Friday (does not apply to O/W only). No permit travel is allowed on major holidays.
Loads up to 9 feet 6 inches wide are permitted without requiring a Pike Pass. Loads over 9 feet 6 inches wide up to 11 feet 6 inches wide (and up to 13 feet 6 inches wide on Cherokee Turnpike only) need a Pike Pass reference number for permitting. The maximum weight for the turnpikes is 108,000 lbs. Weight is paid for on the state permit, and the turnpike does not charge extra above the usual per axle charge.
