Which statement about hydroplaning is true?
Correct answer: It is more likely when the tires are underinflated.
Answer options
- AIt is more likely when the tires are underinflated. Correct
- BDriving through a puddle can never cause it.
- CIt can happen only at speeds above 50 mph.
Why
Tires with too little air lose contact with the road more easily and ride up on a layer of water, as do tires with worn tread. It does not take much water, and it can happen well below 50 mph, so even a puddle can be enough.
