California DMV Permit Test (Class C)Safe Driving PracticesHard
You are driving a vehicle equipped with ABS (Anti-lock Braking System) on a wet road and need to make an emergency stop. What is the correct way to use the brakes?
- APump the brakes rapidly to prevent skidding.
- BEngage the parking brake in conjunction with the foot brake.
- CLightly tap the brakes intermittently to maintain control.
- DApply firm, continuous pressure to the brake pedal without pumping.
Show answer & explanationAnswer & explanation
Correct answer: D. Apply firm, continuous pressure to the brake pedal without pumping.
ABS is designed to prevent wheel lock-up and allow steering during emergency braking. For vehicles with ABS, you should apply firm, continuous pressure to the brake pedal. The system will automatically pump the brakes much faster than a human can, allowing you to steer while braking.
Why the other options are wrong
- A. Pumping the brakes is for vehicles without ABS; it defeats the purpose of ABS.
- B. The parking brake is not designed for emergency stopping at speed and can cause loss of control.
- C. Lightly tapping the brakes will not provide sufficient stopping power in an emergency.
ABS Emergency Braking
When performing an emergency stop in a vehicle with ABS, apply firm, continuous pressure on the brake pedal. The ABS will automatically modulate the brakes to prevent skidding and allow steering.
- ABS prevents wheel lock-up.
- Allows steering during hard braking.
- Requires firm, continuous pedal pressure.
- Do NOT pump the brakes with ABS.
Memory trick: With ABS, just hold it tight, let the system make it right.
