Parts and Accessories Necessary for Safe Operation: Surge Brake Requirements

Final rule.
FMCSA amends the Federal Motor Carrier Safety Regulations to allow the use of automatic hydraulic inertia brake systems (surge brakes) on trailers when the ratios of gross vehicle weight ratings (GVWR) for the towing-vehicle and trailer are within certain limits. A surge brake is a self-contained permanently closed hydraulic brake system activated in response to the braking action of the towing vehicle. The amount of braking force developed by the trailer surge- brake system is proportional to the ratio of the towing vehicle to trailer weight and deceleration rate of the towing vehicle. This action is in response to a petition for rulemaking from the Surge Brake Coalition (Coalition).
