Braking distance is affected by:
- The speed your vehicle is traveling.
- The condition of your brakes and tires.
- The condition of the pavement.
- All of the above. ✓
Answer: D. All of the above.
Braking distance is affected by all of these: your speed, the condition of your brakes and tires, and the condition of the pavement.
Why this is the answer
The handbook defines braking distance as how far you travel while braking, and it ties that distance strongly to speed: higher speeds make stopping distances grow sharply, and doubling speed makes braking distance four times greater. It also says wet road conditions increase braking and stopping distance, and it warns that low tire pressure or bad tread raises hydroplaning risk and that wet brakes may not hold. So speed, brake and tire condition, and pavement condition all change braking distance.
Why the other answers are wrong
- A. The speed your vehicle is traveling. — Speed is only one factor; the passages also show that wet pavement and poor tire or brake condition change braking distance.
- B. The condition of your brakes and tires. — Brake and tire condition matter, but the passages also say higher speed and wet pavement increase braking distance.
- C. The condition of the pavement. — Pavement condition matters, but the passages also tie braking distance to speed and to brake and tire condition.
Remember it
Think three checks before you count on your brakes: how fast you are going, how good the brakes and tires are, and how slick the road is.
