Do You Know Each State’s Semi-Trailer Length Regulations?

Semi-trailer length laws aren’t as complicated as most people make them seem. As an owner of a semi-trailer, apart from maintaining your trailer, you should as well know the length laws of semi-trailers in your state. With time, learn about the laws in other states as well.

These trailers are usually referred to as semi-trucks and semi-trailer trucks because the trailers aren’t assembled with the front part. They don’t come with the front wheels for steering. Hence, the trailer is only functional when it’s linked to a tractor.

From the impressive size, it’s no secret that these beasts of technology reign supreme in any bridge, road, or highway. It’s hard not to notice one. They can carry up to 80,000 pounds and can stretch as long as 75 feet!

These features are awe-inspiring, but they can also be a source of accidents. That’s why state regulations were put in place.

Semi-trailer Length Laws By State

Federal laws make it clear that states have the freedom to permit trailers less than 53 feet on roads that are not funded by the federal government. Additionally, the laws require that states can’t legislate the trailer length to be below 53 feet on access roads and the Interstate.

As per the U.S Department of Transportation;

  • The maximum length in Wyoming, Alaska, Illinois, Idaho, Rhode Island, West Virginia, Vermont, Tennessee, Delaware, New Jersey, Connecticut, Missouri, Nevada, Ohio, Massachusetts, Oregon, New Hampshire, Montana, Nebraska, New York, Utah, South Carolina, North Carolina, South Dakota, North Dakota, Wisconsin, Washington, Pennsylvania, Mississippi, Maryland, Minnesota, Maine, Michigan, Kentucky, and Iowa is 53’0”
  • Kansas, New Mexico, and Arizona have a maximum length of 57’6”
  • Texas has a maximum length of 59’0”
  • Oklahoma and Louisiana have the greatest allowance, with a maximum length of 59’6”
  • Alabama and Florida have a maximum length of 57’0”
  • Hawaii, Georgia, Indiana, and Virginia have a maximum length of 48’0”
  • Colorado has a maximum length of 57’4”

Why Is It Important to Learn Semi-trailer Laws?

Most drivers prefer semi-trailers for transporting their items from one place to another for a good reason: They have lots of space, are sturdy, and are cost-effective. 

Though it might be alright for a trailer to be of a particular length in your state, realize that once you cross borders of a state, you’re entering into a different area with (probably) a whole new set of semi-trailer regulations.

Breaking these laws, knowingly or unknowingly, could cause you to part with a hefty sum or, worse, attract a lawsuit. You’re also at risk of a fatal accident if you don’t know which route to take and which areas are best for your semi-trailer.
