How to Measure

Of course, the width of your Dually pickup truck will be different depending on how you choose to measure it. 

Dually pickup trucks have 2 wheels on each rear axel instead of one, so they are usually 4 inches wider than a regular pickup truck. 

Some truck owners like to measure their trucks by the outside of the wheels or the outside of the fenders on their cab.

However, the correct way to measure your Dually trucks is from the outside of the side mirrors. 

Mirrors on towing vehicles are often wider than the mirrors on normal vehicles so the driver can see more on each side of the car and see what you’re towing.

It’s important to include the mirrors in the measurement of a Dually truck because they often add 15 to 18 inches to the width. 

Even if you pull the mirrors in, they are still adding on extra inches, increasing the width of your pickup truck.

Some truck owners measure by the wheels or fenders if they are getting a custom bed. 

Oftentimes, Duallys are used for extra safety when towing, so if someone does a lot of towing with their Dually they may invest in a custom truck bed that can further provide for their business or towing needs. 

Dually pickup trucks can be the heart and soul of a company due to how much they can tow, so it’s worth it to get a custom truck that can further the success of the business.

State Regulations

There are state regulations for the width, length, and height of a vehicle. 102 inches is the max-width, which translates to 8.5 feet.

Duallys usually never go over the legal width of 8.5 feet, but if they do they will require a special permit. 

The length of most lanes on highways or freeways is 12 feet, so 8.5 feet still gives you plenty of room to travel comfortably.

On average they are 80-84 inches wide, without the mirrors.

Dually trucks have special towing mirrors that are much bigger and wider. Mirrors add about 15-18 extra inches to the total width of the truck.

Many states could have different regulations, so make sure to double check the rules and regulations for each state you are driving through with your Dually. 

Benefits of Dually Trucks

If your car is not wider than the trailer, then you are good to go.

Trailer companies comply with state road regulations when designing trailers.

Dually trucks are also great for towing because of the increased traction from the two extra wheels. 

Having more traction reduces the chances of swaying in high winds.
