- 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.
