Threshold braking means…?
- You pump the brakes several times
- You use all the braking force available without locking the wheels ✓
- You are braking dangerously
- You brake hard and stay on the brakes until the vehicle stops
Answer: B. You use all the braking force available without locking the wheels
Threshold braking means using as much braking force as you can without letting the wheels lock.
Why this is the answer
The handbook describes braking as hard as possible until a wheel is about to lock, then easing pedal pressure slightly and reapplying, keeping as much force as possible without causing a skid. It says not to pump the brakes and to continue until you reach the speed you want. That matches the idea of using all available braking force while avoiding wheel lock.
Why the other answers are wrong
- A. You pump the brakes several times — Pumping the brakes is specifically discouraged in the handbook; threshold braking uses steady pressure with small releases to prevent lock-up.
- C. You are braking dangerously — Threshold braking is described as a controlled technique for a quick stop in your lane, not as dangerous braking.
- D. You brake hard and stay on the brakes until the vehicle stops — Holding hard on the brake until the vehicle stops is not the technique; you must ease pressure when a wheel starts to lock and reapply, rather than staying on the pedal without that adjustment.
Remember it
Squeeze to the edge of a skid, then back off a touch and press again.
