Indiana Trailer Laws & Regulations

Trailers provide a great way to transport large loads without taking up a lot of space on the road. However, there are specific laws and regulations that must be followed when driving a trailer. In Indiana, these laws are outlined in the Indiana Commercial Driver's License Manual.

What Are The Trailer Laws In Indiana?

Drivers in Indiana need a wide-load permit for trailers wider than 102 inches. The maximum length for 2 or more vehicles linked together, with cargo included, is 60 feet. For 3 or more vehicles hooked together, the maximum length is 65 feet.

Does my trailer need a license plate in Indiana? The owner of a trailer that weighs 3,000 pounds or less may apply to the bureau of motor vehicles (bureau) for permanent registration. The fee for this is $82.

Does a utility trailer need a title in Indiana? Yes, you should have a title for your trailer. This answer depends on two factors: the specifics of your trailer and where you live. If your trailer is extremely small or not being used on the road, there's a chance it may not need to be titled. However, this is unlikely as the DMV has a broad definition of a trailer which likely encompasses anything we might think of as a trailer.

The requirement to title your trailer varies by state, so you'll want to specifically research the requirements for where you live.

If you live in a state that requires trailer registration, it's not an opt-in or opt-out situation. You must register your trailer; otherwise, you'll probably face penalties that get worse the longer the trailer goes without being titled. For Indiana, you'll need to fill out an application and provide proof of ownership.

It's important to follow the laws in Indiana when driving a trailer, as there are hefty fines for those who do not abide by the regulations. Understanding these laws is essential if you want to keep yourself and other drivers safe while on the road! So make sure your trailer meets all the requirements before taking it out for a spin!
