Difficulty: EasySkid Control and Recovery

As a truck enters a slick bend, the driver turns the steering wheel, but the vehicle continues pushing straight forward rather than turning. Which action should the driver take to regain steering control?

  1. A
    Turn the steering wheel harder in the direction of the turn while applying firm foot braking.
  2. B
    Engage the auxiliary engine retarder to shift vehicle weight toward the front steer axle.
  3. Stop braking and ease off the accelerator to let the front wheels roll and regain traction.Answer
  4. D
    Accelerate smoothly while holding the steering wheel at a sharp angle to power through the turn.

Answer

Stop braking and ease off the accelerator to let the front wheels roll and regain traction.
In a front-wheel skid, the vehicle continues straight regardless of steering wheel position. The only way to regain steering is to stop braking, ease off the throttle, and allow the front wheels to roll and re-establish traction.

Step-by-Step Solution

1
Identify the situation as a front-wheel skid where the steer tires have lost traction and push straight ahead.
Recognize that directional steering is impossible until the front wheels resume rolling.
Front-wheel skids occur when front tires lose grip due to excessive speed, braking, or slick conditions.
2
Release the brake pedal and ease off the accelerator pedal.
The front tires stop sliding and begin to roll along the road surface.
A rolling tire generates lateral grip and steering force, whereas a locked or sliding tire only slides in the direction of momentum.
3
Steer gently along the intended travel path as traction returns.
The commercial vehicle safely follows the curve.
Smooth, gentle steering inputs prevent initiating a secondary slide once grip is restored.
