The tires begin riding on water and steering feels light. What should the driver do first?
Blue A is on a wet road. An enlarged tire-contact detail shows a water film between the tire and road. The detail has a separate scale.
Correct answer: Slow down gradually and do not use the brakes.
Why
Slow down gradually by easing off the accelerator. Do not use the brakes while hydroplaning, and avoid sudden steering changes. Smooth slowing helps the tires regain road contact.
