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: slowing down on wet roads, keeping tires at proper air pressure, and replacing tires with bad tread all help lower hydroplaning risk.
Why this is the answer
The handbook explains that hydroplaning happens when your tires ride on a thin layer of water instead of the road, and you can lose control and skid. It says tires with low air pressure or bad tread raise the risk, and so does speeding. That means each listed step works against a cause the handbook ties to hydroplaning, so the combined answer fits the passage.
Why the other answers are wrong
- A. Do not speed when the roads are wet. — Slowing down on wet roads helps, but it is only one of the three risk factors the handbook connects to hydroplaning, so it does not cover tire pressure or bad tread.
- B. Use tires with proper air pressure. — Proper tire pressure helps, but by itself it does not address speeding on wet roads or tires with bad tread.
- C. Replace tires with bad tread. — Replacing tires with bad tread helps, but alone it does not cover the need to slow down on wet roads or keep proper tire pressure.
Remember it
In rain, think three checks: slower speed, right tire pressure, and good tread.
