What can be concluded if a vehicle's parking brake must be held manually to keep it stationary?

If a vehicle's parking brake must be held manually to keep it stationary, it indicates a significant malfunction in the braking system. The parking brake is designed to engage and hold the vehicle in place without requiring constant manual effort. When it does not function as intended, this presents a clear safety issue, as it could lead to the vehicle rolling away if parked on an incline or if the regular brakes fail.

In the context of vehicle inspections, one of the critical criteria is that all braking systems, including the parking brake, must operate effectively. A parking brake that requires manual intervention to hold the vehicle stationary is a clear indication that it does not meet this essential safety standard, leading to its failure in the inspection process.

Consequently, the conclusion that the vehicle fails inspection is based on the requirements for safe operating conditions mandated by inspection regulations. Regular maintenance and proper functioning of all braking components are crucial not only for passing inspection but also for ensuring the safety of the driver and others on the road.
