Question 3843

What can you do to avoid hydroplaning?

  1. Drive with properly inflated tires and sufficient tread depth.
  2. Speed up to get across the pooled water as quickly as possible.
  3. Not drive in the ruts left by the vehicles ahead.
Show answer and explanation

Correct answer: Drive with properly inflated tires and sufficient tread depth.

Hydroplaning occurs when a tire cannot channel away all the water and floats on top of it. The tread grooves channel the water away, so you need sufficient tread depth and the correct tire pressure. Accelerating over pooled water makes things worse, because at higher speeds the tire has to channel away more water in less time.
