Zorluk: KolaySkid Control and Recovery

While pulling away from a wet gravel shoulder onto a paved roadway, excessive throttle causes the vehicle's drive wheels to spin freely and slide sideways. What is the most effective immediate action the driver should take to recover from this drive-wheel skid?

  1. A
    Engage the engine retarder to slow down the spinning drive wheels quickly.
  2. Ease off the accelerator pedal to allow the drive wheels to regain traction.Cevap
  3. C
    Apply firm service braking while holding the steering wheel straight ahead.
  4. D
    Steer sharply away from the direction in which the rear of the vehicle is sliding.

Cevap

Ease off the accelerator pedal to allow the drive wheels to regain traction.
In a drive-wheel skid caused by acceleration on a slippery surface, the drive wheels spin because too much power has been applied. Easing off the accelerator immediately removes the excess drive torque, enabling the drive tires to resume rolling and regain lateral grip with the road surface.

Adım Adım Çözüm

1
Recognize the cause of the drive-wheel skid as excessive drive wheel spin from over-acceleration.
Identified that the drive tires have lost rotational grip with the slippery surface.
Correct recovery requires eliminating the force causing the traction loss.
2
Immediately take the foot off the accelerator pedal without hitting the brakes.
The drive wheels stop spinning faster than vehicle speed and resume normal rolling rotation.
Removing power allows the tires to regain traction with the road surface naturally.
