Surge or inertia braking systems can be used on a trailer with a GVW of what amount?

The choice indicating "more than 15000 lbs" for surge or inertia braking systems on a trailer is rooted in regulations that establish when certain braking systems are required based on the Gross Vehicle Weight (GVW) of trailers.

Surge or inertia braking systems are typically designed for use with lighter trailers and are effective under specific weight limits. Once the weight of the trailer exceeds 15,000 lbs, it often necessitates a more robust braking system, such as electric brakes or hydraulic brakes, to ensure proper stopping power and safety for significant loads.

This weight threshold is particularly important as heavier trailers can exert greater forces during braking. In this context, exceeding 15,000 lbs emphasizes the need for braking systems that can handle these forces effectively. Therefore, trailers exceeding this weight must adhere to stricter requirements to ensure they can be safely operated.
