When driving a vehicle without ABS, what braking method is taught for an emergency stop?
- A.Lock all the wheels and steer with the hand brake
- B.Brake in one long, unchanging application no matter what the wheels do
- C.Use only engine braking and never touch the service brakes
- D.Controlled braking: apply the brakes as hard as you can without locking the wheels, and ease off slightly if they start to lock
Correct answer
D. Controlled braking: apply the brakes as hard as you can without locking the wheels, and ease off slightly if they start to lock
Why
Controlled braking squeezes out maximum stopping power while keeping the wheels rolling and able to steer. If a wheel does lock, easing off just enough to let it roll restores grip without giving up the stop.
