When parking on an uphill gradient, it is recommended that the front wheels face away from the curb. In manual transmission vehicles, the parking brake can be engaged to help keep the vehicle stationary. However, it is recommended to use it, as the parking pawl in the gearbox could fail due to stress or another vehicle striking the car, causing the car to roll. While most automatic transmission vehicles have parking brakes, it is often not engaged by American drivers when parking. The mechanism may be a hand-operated lever, a straight pull handle located near the steering column, or a foot-operated pedal located with the other pedals.

In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. Parking brakes often consist of a pulling mechanism attached to a cable which is connected to two wheel brakes. In road vehicles, the parking brake, also known as a handbrake or emergency brake ( e-brake), is a mechanism used to keep the vehicle securely motionless when parked.
