Zorluk: OrtaSkid Control and Recovery

During a turn at a rain-slicked intersection, the front wheels of a vehicle lose grip and the front end continues traveling in a straight path despite the steering wheel being turned. What action should be taken to allow the front tires to regain steering traction?

  1. A
    Turn the steering wheel more sharply into the corner to force tire bite
  2. Ease off the accelerator pedal and allow the vehicle to slow down without harsh brakingCevap
  3. C
    Activate the auxiliary engine retarder to quickly decelerate the drive axle
  4. D
    Apply firm service brakes immediately while holding the steering wheel at full lock

Cevap

Ease off the accelerator pedal and allow the vehicle to slow down without harsh braking
In a front-wheel skid, the vehicle continues straight because the front tires have exceeded their maximum available lateral traction. The standard CDL recovery procedure requires letting the vehicle slow down by releasing the accelerator pedal and avoiding sudden, hard braking, which allows rolling traction to return to the steer axle.

Adım Adım Çözüm

1
Recognize the front-wheel skid condition
Identify that the vehicle is understeering and failing to respond to steering angle inputs due to lost front-tire traction.
Front-wheel skids occur when front tires slide along the road surface rather than rolling in the intended turning direction.
2
Release the accelerator smoothly and avoid aggressive brake applications
The forward momentum decreases naturally without locking any wheels.
Slowing the vehicle reduces centrifugal forces and permits the front tires to regain their grip on the pavement.
3
Ease the steering wheel back toward straight-ahead until traction returns
Tire friction transitions from dynamic sliding back to static/rolling grip, restoring directional control.
Excessive steering angles maintain tire saturation and extend the slide.
