Is it necessary to use the parking brake to secure the vehicle during a stop, especially on slopes?

Question

DentroTest · Accepted Answer

Although the service brake (pedal) is commonly maintained during very short stops (like a Stop sign or traffic light on flat ground), the parking brake is the system specifically designed to ensure the mechanical immobilization of the vehicle. Its use is mandatory and necessary to guarantee safety if the stop is prolonged, if the driver must leave their seat, or fundamentally, on slopes to prevent rollback. Relying solely on the service brake is unsafe, as a distraction, a foot slip, or a loss of pressure could cause an accident.
