Trailers are ideal for outdoor lovers who want to explore Michigan’s abundance of lakes, campgrounds and scenic vacation spots. However, many people don’t understand the complex rules and regulations for using and buying a trailer in Michigan. Before you make that all-important purchase, here is a guide to everything you should know about Michigan trailer laws.

Do You Have a Case?

When buying a trailer in Michigan, register it

All trailers in Michigan must be registered with the Secretary of State. If your trailer weighs more than 2,500 lbs., including trailer coaches, you will also need a title.

In addition, motorists must have both registration and title for all trailer coaches; including pop-up campers, travel trailers and fifth-wheel campers.

Those who own trailers weighing more than 9,999 lbs. should contact the Secretary of State for rules pertaining to larger vehicles.

Finally, drivers must display a current license plate on their trailer at all times. License plates issued for trailers are permanent and non-transferable.

Insurance rules for trailers

You will have to insure your trailer if it is considered a “motor vehicle” under Michigan No-Fault law. The Michigan Insurance Code (MCL 500.3101) defines a motor vehicle as follows:

A vehicle, including a trailer, that is operated or designed for operation on a public highway by power other than muscular power and has more than 2 wheels.

Accordingly, if your trailer has three or more wheels, you must insure it, including travel trailers and tractor-trailers. Michigan No-Fault insurance does not cover vehicle contents. Therefore, if you are hauling a boat or motorcycle, you should insure these valuable items separately.

If you own a two-wheel trailer, you are not required by law to insure it. However, it is a good idea to have insurance in the event you are involved in an accident.

Know the size limits for trailers

Consider the size regulations when buying a trailer in Michigan They are as follows:

Trailer length: 45 feet
Total length: 65 feet
Width: 102 inches (this width may be exceeded if the trailer has an “appurtenance,” a pre-installed appendage that is an integral part of the vehicle)
Height: 13 feet, 6 inches
