Question

Difficulty: EasyHydroplaning and Wet Road Traction Loss

A driver traveling through rain notices the vehicle's tires floating on a layer of water, causing a loss of steering response. What action should the driver take immediately?

  1. Smoothly remove pressure from the accelerator and steer straight until the tires regain contact with the road.Answer
  2. B
    Slam hard on the brake pedal to rapidly reduce speed before the vehicle swerves.
  3. C
    Steer sharply toward the road shoulder to exit the water accumulation as fast as possible.
  4. D
    Depress the accelerator pedal to increase tire rotation speed and break through the surface water.

Answer

Smoothly remove pressure from the accelerator and steer straight until the tires regain contact with the road.
Gradually releasing the gas pedal allows aerodynamic drag and engine drag to reduce vehicle speed, giving tire treads the necessary time to clear water and re-engage with the road surface.

Step-by-Step Solution

1
Identify the dynamic hazard
Recognize hydroplaning, which occurs when standing water builds up faster than tire tread can channel it away, separating tires from the pavement.
Loss of tire-to-road contact eliminates steering authority and braking control.
2
Select the correct emergency recovery response
Decelerate smoothly by easing off the throttle while maintaining a straight steering angle.
Sudden braking or aggressive steering during hydroplaning leads to wheel lockup or violent vehicle rotation when grip returns.
