Ohio Oversize Permit, Wide and Heavy Haul Information

Oversized loads up to 12 feet wide are permitted to travel 30 minutes before sunrise to 30 minutes after sunset, including weekends. Loads over 12 feet wide are allowed until 3 pm on Friday to Sunday from April 1 to November 30.

Oversized loads or vehicles over 12 feet are not allowed to travel within many counties in Ohio from 6:30 am - 9 am and 4:30 pm - 6 pm, Monday through Friday. You can find county-specific information in the Ohio Provisions Form OS-1A. Oversized loads are typically not allowed to travel starting at noon the weekday before a major holiday and ending at sunrise the following weekday. All stops along the route for fuel, food, etc., must be included in the permit. Signs, flags, and lights may be required when transporting oversized or heavy haul loads to ensure the safety of other motorists and vehicles on the road. For oversized vehicles over 10 feet wide, over 14 feet and 6 inches in height, or over legal length, an “Oversize Load” sign is mandatory on the front and rear. All over-dimension vehicles and loads must have flags displayed. There should be flags at each corner of the vehicle or load and flags at the widest part for overwidth loads. Overlength vehicles and loads with a rear overhang of 4 feet or more must have a flag at the rear of the overhang. If the overhang is wider than 2 feet, there must be two flags displayed on the rear. For any over-dimensional vehicle, headlights must be on during any movement. At night, the overhang must be lit. Permits for oversized vehicles in Ohio are valid for five days. Additionally, a permit is required before entering the state.
