Have you ever wondered about the law concerning the protrusion of items from a vehicle in your state? For example, when you’re hauling a ladder or lumber for that new project. Most states have different rules, so you need to have the red flag and know the limitations of protrusion lengths your state legally permits. 

If you have something sticking out too far from your car or truck, you can be issued a citation. Even worse, a fine. We’ll go over the basics of having something protruding from the front or back of your vehicle and what the limitations are in your state.

Guidelines for Transporting Large Items

Learn how far a ladder can extend from your vehicle and apply the best road practices.

guidelines for transporting large items

1. Secure Your Item Properly

One of the most important things here is to ensure you don’t lose whatever you’re moving. Therefore, ensure your long item is properly secured to your vehicle or truck. When securing lighter items, we suggest using a small rope if you can tie a good knot. If you’re not the greatest with knots, consider a double tie if this is the only option.  

For heavy and long items (lumber, poles, pipe, ladders, etc.), use ratchet straps to secure them when possible. We do not recommend using bungee cords to secure anything under any circumstances. They are too stretchy and can’t be 100% counted on. The last thing you need is an insurance claim.

2. Follow the Red Flag Rules

Do I have to tie a red flag on anything that sticks out of the back or front of my vehicle or truck? The rule of thumb on this is if it sticks out more than 3 feet, yes. It doesn’t matter if it extends 3 feet from the front bumper or 3 feet from the rear bumper down low, on top of the hood or in racks. However, if it protrudes more than 3 feet in either direction, you must attach a red-colored warning flag to each protruding end.

3. Check Your Vehicle Overhang Laws

Considering the safety of other motorists and public property, there are various laws in place to limit how far an item can overhang or protrude from the rear end of vehicles. They also cover properly marking the item being transported at each end. As mentioned earlier, if you don’t correctly flag or mark the protrusion, you could be subject to a ticket, a fine or both.  

The USDOT has federal regulations that cover this area of the law. It says that if you have something protruding over 3 feet in the front or 4 feet from the rear of the car or truck, it must be properly marked with a red or orange safety flag. Keep in mind that objects protruding more than 4 inches from the sides of a vehicle must be appropriately marked.

To learn how far a ladder can stick out of your car, review your local regulations. Some examples include:

  • Arizona, Delaware, Maine, Maryland, Pennsylvania, Rhode Island and Vermont: Loads can extend up to 3 feet in the front and 6 feet in the rear. 
  • Colorado: Loads cannot extend beyond 4 feet from the front or 10 feet from the rear without a permit.
  • Florida: Any trucks transporting boats or automobiles can extend up to 9 feet from the rear or 10 feet when transporting trees. 
  • Hawaii, Idaho and North Dakota: Loads can extend up to 3 feet in the front and 10 feet beyond the rear.
  • Kentucky: Loads can extend up to 3 feet in the front and 5 feet past the rear.
  • Louisiana: Loads can extend no more than 4 feet in the front and 8 feet in the back.
  • Michigan and Nebraska: Any load size is allowed as long as the load doesn’t exceed the vehicle’s overall length.
  • Mississippi: Loads can extend up to 3 feet in the front and 15 feet beyond the rear. 
  • Nevada: Loads can extend 10 feet from a vehicle’s front and rear. 
  • New Mexico: Special permits are required for loads extending 3 feet in the front and 7 feet from the rear.
  • Oregon: Loads can extend 3 feet in the front and 5 feet from the back of a vehicle.
  • Washington: Loads can extend 3 feet in the front and 15 feet from the rear.
  • Wyoming: Loads can extend up to 4 feet from the vehicle’s front and rear. 

The Right Way to Mark Items

Whether you want to transport a ladder on your car roof or drive with items sticking out of your vehicle, follow these guidelines:

  • Daylight hours: During this time of the day, protrusions can be marked with a red or orange safety/warning colored flag. Flags must be a minimum of 18 inches square.
  • Nighttime hours: During the hours of darkness, objects protruding from vehicles must be illuminated with a red lamp placed at the far rear extreme of the item protruding from the rear.
