Michigan has specific requirements for boat trailers. For further information, contact the Michigan Secretary of State at 517-322-1460, or call or visit one of the branch offices. The law requires the following for trailers.

  • Trailers must be licensed and registered.
  • If the gross weight of the vessel and trailer exceeds 3,000 pounds, the trailer must be equipped with brakes.
  • Trailers must have proper lighting, including turn signals, taillights, and brake lights. All trailer lights must be maintained in an operable condition—same as when the trailer was manufactured.
  • All towing vehicles must be connected to the trailer by a safety chain or cable of sufficient strength to maintain connection under all conditions.
