How can you lower the risk of hydroplaning?
- Do not speed when the roads are wet.
- Use tires with proper air pressure.
- Replace tires with bad tread.
- All of the above. ✓
Answer: D. All of the above.
All of the above: avoid speeding on wet roads, keep tires properly inflated, and replace tires with bad tread.
Why this is the answer
The manual explains that hydroplaning happens when tires ride on water and steering and traction can be lost. It says this usually happens at higher speeds and can also happen when tires are worn or not inflated correctly. In heavy rain it advises driving slower, and it says tires in good shape with deep grooves make hydroplaning less likely. Elsewhere it tells you to replace badly worn tires and check pressure as your owner's manual or a tire store advises. Those points match slowing down, correct air pressure, and replacing bad tread.
Why the other answers are wrong
- A. Do not speed when the roads are wet. — Avoiding high speed on wet roads is one part of the handbook's advice, but it does not also cover tire pressure and worn tread, so it is incomplete as the full answer.
- B. Use tires with proper air pressure. — Correct tire pressure is one part of the advice, but by itself it leaves out slowing down and replacing tires with bad tread.
- C. Replace tires with bad tread. — Replacing tires with bad tread is one part of the advice, but alone it does not include slowing down or maintaining proper tire pressure.
Remember it
When the road is wet, think speed, pressure, tread: slow down and keep your tires properly inflated and not worn.
