In many states, trailers with a GVWR of 1,500 pounds or greater are required by law to have what equipment?

Trailers with a Gross Vehicle Weight Rating (GVWR) of 1,500 pounds or greater are required by law to be equipped with brakes due to safety regulations aimed at controlling the stopping power of the trailer when it is being towed. This requirement is rooted in the understanding that heavier trailers can exert significant force during braking, which can affect the towing vehicle's ability to stop safely.

When brakes are included on the trailer, they assist in slowing down or stopping the trailer's motion, particularly when going downhill or when sudden stops are needed. Adequate braking systems help to ensure that both the towing vehicle and the trailer maintain control, reducing the risk of accidents caused by trailer sway or insufficient stopping power.

While reflective tape, emergency lights, and safety chains are important elements for increasing visibility and ensuring safety on the road, they do not serve the primary function of stopping the trailer. Therefore, while those features may be required or recommended for various safety reasons, the legal requirement pertains specifically to the inclusion of a braking system for trailers of this weight.
