Worn or bald tires:
- Can make turning more difficult.
- Are likely to hydroplane.
- Can increase your stopping distance.
- All of the above. ✓
Answer: D. All of the above.
Worn or bald tires can make turning more difficult, are likely to hydroplane, and can increase your stopping distance, so all of these choices are correct.
Why this is the answer
The handbook warns that tires with bad tread raise the risk of hydroplaning, which is when the vehicle rides on a thin film of water and the tires stop touching the road, so you can lose control and skid. It also explains that wet roads stretch out your braking distance and that you should slow down and leave more space. Tires are your only contact with the road, so tread that is worn away leaves less grip for turning and for stopping.
Why the other answers are wrong
- A. Can make turning more difficult. — Harder turning is only one of the effects of worn tread, so this choice leaves out the others.
- B. Are likely to hydroplane. — Hydroplaning risk is real with bad tread, but it is just one part of the answer rather than the whole of it.
- C. Can increase your stopping distance. — Longer stopping distance is only one result of worn tires, so picking it alone is incomplete.
Remember it
Think of tread as the tiny channels that squeeze water out from under the tire: shallow tread means less grip for turning and stopping, and more sliding on water.
