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

Surge (inertia) braking works by using the trailer’s own momentum to activate the brakes through a mechanism in the hitch, so no separate brake controller is needed. This type of brake is particularly suited for heavier trailers because the stopping force needed for a large mass is substantial and a simple mechanical or hydraulic actuation can reliably apply the brakes as deceleration occurs. Because of that, surge or inertia braking systems are permitted on trailers with a GVW greater than 15,000 pounds. Lighter trailers usually don’t use this system, which is why the other options don’t fit as well.
