For GVWR of 36,000 pounds or greater, the apparatus must be equipped with which braking feature?

• A. Hydraulic braking system
• B. Primary braking system
• C. Auxiliary braking
• D. Electronic braking only

Answer: (C)

Heavy apparatus with a GVWR of 36,000 pounds or greater must have an auxiliary braking system to supplement the primary brakes. This extra braking capability helps manage speed on long descents and under heavy load, reducing heat buildup in the main brakes and maintaining better control. The auxiliary system can be an engine brake, transmission retarder, or similar device, and is designed to work alongside the primary hydraulic braking system rather than replacing it. The other options describe parts of the standard braking setup or imply an electronic-only solution, which doesn’t capture the required supplemental feature.
