A driver is operating a vehicle equipped with anti-lock brakes (ABS). In an emergency braking situation, how should the driver apply the brakes?
- AApply firm, continuous pressure to the brake pedal.
- BApply gentle pressure to avoid activating the ABS.
- CPump the brakes rapidly to prevent skidding.
- DRelease the brake pedal if the wheels lock up.
Show answer & explanationAnswer & explanation
Correct answer: A. Apply firm, continuous pressure to the brake pedal.
With ABS, the system automatically pumps the brakes much faster than a human can, preventing wheel lock-up and allowing steering control. The driver's role is to apply firm, continuous pressure.
Why the other options are wrong
- B. ABS is designed to activate in emergency situations; avoiding its activation can lead to longer stopping distances or loss of control.
- C. Pumping the brakes is for vehicles without ABS; it defeats the purpose of ABS.
- D. Releasing the brake pedal removes the ABS's ability to control braking, increasing stopping distance.
Using ABS Brakes
When driving a vehicle equipped with Anti-lock Braking System (ABS), in an emergency stop, apply firm, continuous pressure to the brake pedal; do not pump the brakes.
- ABS prevents wheel lock-up.
- Allows steering during hard braking.
- Feel vibration/pulsation in pedal is normal.
- Do not pump the brakes.
Memory trick: ABS is your friend, firm pedal to the end!
