Maine Revised Statutes Title 29-A. Motor Vehicles § 2385. Protruding objects and trailers

1. Warning device. A vehicle carrying an object that projects more than 4 feet from the rear must carry, at or near the rear of the object:

2. Logs. During the hours when lights are required, a vehicle carrying logs that project more than 4 feet from the rear of the vehicle must display a red reflector or reflectorized paint on the end of the log projecting furthest to the rear. The reflector or reflectorized paint must be of sufficient size and properly located and maintained so as to reflect, at night on an unlighted highway, the undimmed headlights of a vehicle approaching from the rear for at least 200 feet.

3. Safety chains. A trailer, semitrailer or vehicle being towed must, in addition to the tow bar or coupling device, have a safety chain or steel cable so attached as to prevent breakaway from the towing vehicle.

The chain or steel cable must be made of not less than 1/4-inch wire.

This subsection does not apply to truck tractor and semitrailer units equipped with 5th wheel mechanism.

4. Trailers and tiny homes. A trailer, tiny home or semitrailer that is wider than the vehicle towing it must be equipped with reflective material or a lamp on each front corner that is visible to oncoming traffic.
