Difficulty: EasySkid Control and Recovery

If your truck encounters standing water at highway speed and begins hydroplaning, which action is the most effective way to regain vehicle control?

  1. A
    Activate the auxiliary engine brake to rapidly decrease wheel rotation speed.
  2. Ease off the throttle and refrain from braking to allow the tires to regain contact with the pavement.Answer
  3. C
    Quickly jerk the steering wheel away from the slide direction to force the front tires to track.
  4. D
    Slam on the service brakes with maximum pedal pressure to bring the vehicle to an immediate halt.

Answer

Ease off the throttle and refrain from braking to allow the tires to regain contact with the pavement.
When hydroplaning occurs, the vehicle rides on a cushion of water separated from the pavement. Easing off the throttle while staying off the brakes keeps the tires rolling, allowing the tread channels to displace standing water and regain traction.

Step-by-Step Solution

1
Identify the loss of traction caused by water buildup beneath the tires.
Driver recognizes hydroplaning is occurring and avoids reflexive panic actions.
Immediate awareness prevents panic-induced braking or abrupt steering.
2
Ease off the throttle smoothly without applying the service brakes or engine retarders.
The rolling tires disperse the water layer and restore direct physical contact with the road surface.
Maintaining rolling wheels allows the tread grooves to clear water effectively and safely restore directional control.
