How should the parking brake function during inspection?

The parking brake must hold the vehicle stationary on an incline to ensure that it is functioning correctly. This is a critical safety feature designed to prevent the vehicle from rolling away when parked, especially on sloped surfaces. During a state inspection, checking its effectiveness on an incline helps confirm that the parking brake can securely hold the vehicle in place under various conditions.

A properly functioning parking brake is essential for vehicle safety, especially in situations where the vehicle needs to be kept stationary when parked. The other options may not accurately reflect the safety requirements and standards set for parking brake inspection. For example, a parking brake that only works when the engine is running or has any faults that allow the vehicle to roll would not meet safety standards. Likewise, the parking brake does not need to engage automatically when the engine is turned off; manual engagement is standard practice.
