Missouri Trailer and Towing Laws

09/25/24

Missouri’s winding rural roads and busy communities see many vehicles towing trailers, both camper trailers and utility trailers of many types and sizes. The state describes a trailer as the following:

“a unit attached to and towed by a motorized vehicle designed to carry property and/or passengers. A trailer cannot be motorized or self-operable.”

Like all states, Missouri has laws regulating the safe use and operation of trailers. These regulations help to keep Missouri motorists safe while sharing the roadway with vehicles towing trailers.

Types of Trailers Found in Missouri

Missouri’s definition of towing trailers includes any of the following:

  • Camping trailers
  • Utility trailers
  • Boat trailers
  • Farm wagons
  • Kit trailers
  • Flatbed trailers
  • Livestock trailers
  • Homemade trailers, and
  • Semi-trailers

Trailers in Missouri must be registered and titled with the exception of hay and cotton trailers and tow dollies.

Titling and Registering a Trailer in Missouri

After purchasing a trailer in New Jersey, the purchaser has up to 30 days to title the trailer and pay sales tax. Failing to title the trailer within 30 days results in a $25.00 penalty and an additional $25.00 penalty for every month further that it remains unregistered for a maximum penalty of $200.00.

To title a trailer, the owner must have the title certificate or a manufacturer’s statement of origin (MS0) unless the trailer was an out-of-state purchase from a state that doesn’t require a trailer title or registration. Farm trailers and kit trailers only require a bill of sale or proof of purchase. Title fees for Missouri trailers are $8.50 and the registration fee is $750 for one year, $22.50 for three years, or $52.50 for a permanent registration.

Trailer purchasers can use the state’s calculating tool to estimate their sales tax.

Inspection Requirements for Homemade Trailers in Missouri

Homemade trailers in Missouri require an inspection by the Missouri State Highway Patrol for a $25.00 inspection fee or by an officer from the Sheriff’s Department in your county. After the inspection, a homemade trailer owner must apply for a title with a completed application, fee payment, and a $14.50 processing fee as well as $13.50 for the license plate.

Lighting and Signal Laws for Missouri Trailers

Trailers in Missouri must have two red taillights, two red reflectors, and a white light illuminating the trailer’s license plate.

A trailer must have turn signal lights unless a driver can use visible hand signals. To measure hand signal visibility, the distance from the steering post’s center to the left outside of the cab’s body or the load must be less than 24 inches or the distance from the top of the steering post to the rear end of the body or load must be less than 14 feet.
