Which system must be inspected on vehicles and trailers if the gross weight exceeds 7,500 lbs?

The brake system is critical for ensuring the safe operation of vehicles and trailers, especially those with a gross weight exceeding 7,500 pounds. Heavier vehicles require more robust braking capabilities to effectively stop, which is why inspections focus on this system for safety compliance. A properly functioning brake system reduces the risk of accidents by ensuring that the vehicle can stop reliably and maintain control, even under heavy loads.

While the other systems, such as the exhaust, steering, and suspension, are also important for overall vehicle safety, the brake system specifically addresses the unique challenges posed by larger vehicles. It includes components such as brake pads, rotors, and hydraulic systems that must be in good condition to handle the increased demands of heavier weights. Regular inspections of the brake system ensure that any wear or mechanical issues can be addressed before they lead to failure, thus safeguarding not only the vehicle occupants but also other road users.
