Hauling an overhanging cargo poses dangers to your vehicle and other road users. To keep the roads safe for everybody, the DOT and states have rules guiding the transportation of loads that hang out of a truck.
We’ve researched this topic and provide state-by-state rules regarding overhang limits.
Hopefully, this information will keep you and other road users safe and help you avoid traffic fines.
Here’s how far can something hang out of a truck
It depends on your state of residence. All over the USA, states have various overhang limits and a few of them have no restrictions. The range is from a few feet to 15 feet in Washington.
Here are the numbers per state.
Department of Transportation Regulations on Overhanging Cargo
Under the Federal Size Regulations law, the DOT allows trucks to overhang a cargo by:
- 3 feet in front
- 4 feet in the rear
- 4 inches by the sides
According to the DOT, a truck driver must use proper markings if a cargo overhangs more than the stipulated distance.
And you must use markings that show the maximum width and length of overhand to warn other road users.
However, states have different rules for overhanging cargo. Below, we look at the rules for each state when hauling oversized loads.

- New York,
- North Carolina,
- South Dakota,
- and Wisconsin.
Many of these states make exceptions in specific cases to allow vehicles to overhang their load beyond the legal limit. But you may require special permits, visual signs and sometimes escorts.
States also differ in their measurement of the overhang.
Some measure the protrusion from the extreme end of the truck’s bed or bumper. Other states measure from the nearest axle or the last point of support.
What If You Exceed the Overhang Limit?
In most states, you must mark the overextending load with bright signs. The most common signs are a red side marker lamp mounted on the load to show its maximum overhang.
You may need to hang a marker lamp on the sides and the front and rear of the vehicle in locations that are clearly visible to other road users.
The marker lamps must be illuminated at night or whenever the road condition requires the use of headlamps.
Commercial vehicles transporting a load which protrudes beyond the rear by 4 feet or over the sides by over 4 inches must mark the longest extremity of the load with red or orange fluorescent warning flags measuring at least 18 inches square.
You need only one warning flag if the width of the overhanging load does not exceed 2 feet and two flags if it extends beyond that.
While every state of the USA allows trucks to carry overhanging loads, many of them will only permit an extension of 3 feet in front and 4 feet beyond the rear.
However, almost all of them allow you to extend the overhang with permits and a few don’t even have any limit so long as you stay within your truck’s legal length.
Because laws are fluid, check with the DOT of your state before hauling an oversized cargo with your truck. Use relevant warning signs and stay safe on the road!
