If your vehicle starts to lose traction because of water on the road, you should:

  1. Drive at a constant speed to gain better traction.
  2. Apply the brakes firmly to prevent your vehicle from sliding.
  3. Slow down gradually and not apply the brakes. ✓

Answer: C. Slow down gradually and not apply the brakes.

Slow down gradually and do not apply the brakes.

Why this is the answer

The rain section says that when your vehicle starts to lose traction, you should decrease your speed even more. It also explains that hydroplaning can cause a complete loss of traction and steering control, and that lower speed helps in heavy rain. The skid guidance adds that hard braking can make a skid worse. Together, these passages support easing off and slowing gradually instead of braking firmly or holding speed.

Why the other answers are wrong

Remember it

When water takes away grip, slow gently and keep your foot off the brake pedal.
