Oversize permits for Ohio are valid for a period of five days. It is essential to obtain the permit before entering the state.


Travel is permitted from one-half hour before sunrise to one-half hour after sunset, including weekends, for loads up to 12 feet wide. For loads exceeding 12 feet in width, travel is allowed until 3:00 PM on Friday, Saturday, and Sunday, as well as on Fridays from April 1 through November 30. Continuous travel is allowed for overweight loads, provided they are not over 53 feet in trailer and load length and can maintain the pace of traffic.


The movement of vehicles or loads exceeding 12 feet in width is restricted within numerous counties between 6:30 a.m. – 9:00 a.m. and 4:30 p.m. – 6:00 p.m. from Monday through Friday. A comprehensive list of these counties can be found in the Ohio Provisions Form OS-1A, a necessary permit accompaniment. Oversize and overweight loads are typically prohibited from traveling starting at noon on the weekday preceding major holidays until sunrise on the following weekday. Notably, Ohio does not permit any deviations from the authorized route for purposes such as fuel or food, as indicated in the provision sheet. Any planned stops, including truck stops, should be explicitly included in the issued permit.


The driver is required to make a phone call from a designated pullover area to obtain clearance for the Turnpike. Permits are issued at the entering toll plaza. Continuous travel is allowed for loads with a maximum width of 10 feet. Loads exceeding 11 feet in width or 112 feet in length require a pilot car and must obtain prior authorization. The maximum height is 13 feet 6 inches during the construction season and 14 feet at other times (it is advisable to check ahead for any changes). Without pre-approval, the maximum length allowed is 112 feet. The maximum gross weight permitted is 90,000 pounds without a 2-day pre-approval. Toll charges typically amount to about $20 for a standard trip, $10 for overwidth, and an additional $10 for lengths exceeding 75 feet. Additional overweight charges, approximately $70.00, apply for loads up to 90,000 pounds traveling the length of the Turnpike.

Flags must be prominently displayed on all over dimensional vehicles and loads. Over width loads should have flags positioned at each corner and two flags at the widest points of the vehicle or load. For overlength vehicles/loads or those with a rear overhang of 4 feet or more, a single flag at the extreme rear is required if the overlength or projecting part is two feet wide or less.
