During the parking brake check, what is the procedure to confirm its effectiveness?

To confirm the effectiveness of the parking brake during the pre-trip inspection, the appropriate procedure involves putting the transmission in drive while the parking brake is engaged and attempting to accelerate. This test reveals whether the parking brake is functioning correctly by checking if the vehicle remains stationary despite the application of power through the accelerator.

When the parking brake is properly engaged, the vehicle should not move forward at all when you try to accelerate. This clearly demonstrates its holding capability, which is crucial for safety when the vehicle is parked. If the vehicle does move, it indicates that the parking brake may not be effective, and it could pose a safety risk when parked on an incline.

The other options focus on scenarios that do not adequately test the effectiveness of the parking brake in a practical manner, disregarding the specific requirement to confirm that the vehicle remains stationary when the parking brake is engaged and power is applied. This could lead to assumptions about the brake's readiness without proper assessment.
