What is the requirement for trailers under 3000 pounds GVWR?

For trailers with a Gross Vehicle Weight Rating (GVWR) under 3000 pounds, the requirement is that they are not required to have brakes. This regulation is based on safety standards which determine that lighter trailers typically do not necessitate braking systems because their weight does not pose a significant risk of loss of control or increased stopping distance when towed by a vehicle.

Trailers weighing 3000 pounds or more, on the other hand, generally have stricter braking requirements to ensure adequate stopping power and safety during operation. The absence of a braking requirement for lighter trailers aims to simplify regulations and reduce costs for owners while still maintaining safe towing practices.

This context also clarifies why other options do not apply. Trailers that are less than this weight threshold do not need brakes on all wheels, a single brake on one axle, or emergency brakes, as these measures are unnecessary due to the lighter weight and reduced dynamics involved.
