What action should you take if your vehicle is hydroplaning?
- Brake hard, applying as much force as possible
- Brake gently and quickly pull over
- Have your vehicle checked by a mechanic
- Without braking, decelerate and drive straight ahead ✓
Answer: D. Without braking, decelerate and drive straight ahead
If your vehicle is hydroplaning, ease off the accelerator and keep the vehicle driving straight ahead without braking.
Why this is the answer
The handbook's emergency chapter lists exactly this response: when hydroplaning happens, decelerate and drive straight, and never brake. The reason is given on the previous page: in hydroplaning the tires lose contact with the road and float on a film of water, so the driver instantly loses control of steering and braking. Since you can't steer or brake effectively anyway, your job is to let speed drop smoothly while holding the wheel steady until the tires grip again.
Why the other answers are wrong
- A. Brake hard, applying as much force as possible — Hard braking is the opposite of what the handbook says, and because you have lost control of braking while the tires float, it will not help you.
- B. Brake gently and quickly pull over — Braking is ruled out, and pulling over means steering, which you can't do reliably while the steering feels very light and the tires are off the road surface.
- C. Have your vehicle checked by a mechanic — A mechanic check addresses prevention, such as tire tread and inflation, not what you do in the moment when the vehicle is already hydroplaning.
Remember it
Think of the tires as floating: let off the gas, hold the wheel straight, and keep your foot off the brake until the steering feels normal again.
