NFPA 1901 requires auxiliary braking systems on vehicles with GVWR of what amount?

• A. 18,000 pounds
• B. 24,000 pounds
• C. 36,000 pounds
• D. 48,000 pounds

Answer: (C)

NFPA 1901 requires an auxiliary braking system on heavy fire apparatus to boost braking capacity and reduce brake fade when the vehicle is fully loaded. The standard specifies this auxiliary system for vehicles with a GVWR of 36,000 pounds or more, meaning when the maximum operating weight (including cargo, crew, and fuel) reaches 36,000 pounds or higher, the auxiliary brake must be installed. This helps ensure safer, more controllable stops on heavy apparatus, especially during long descents or high-speed braking. Lighter vehicles under that threshold do not require the auxiliary system under the standard.
