Practice question

In emergency stab braking, what is the correct sequence of actions?

  1. Brake as hard as you can, release when the wheels lock, reapply when the wheels start rolling
  2. Brake gently, then coast
  3. Pump the brakes repeatedly
  4. Hold the brakes in until the vehicle stops

Answer: A — Brake as hard as you can, release when the wheels lock, reapply when the wheels start rolling

Emergency stab braking is about using full braking force to push the brakes to their limit, then releasing briefly when the wheels lock and immediately reapplying once they start rolling again. The idea is to use intense braking to reach the point where tires briefly lock, then regain traction to continue braking effectively. This approach maximizes stopping power on vehicles without ABS. If the vehicle has ABS, you should not release the brakes; keep firm pressure and let the system pulse to prevent wheel lock.
