Zorluk: OrtaSkid Control and Recovery

When heavy braking on wet asphalt locks the drive wheels and causes the rear of the vehicle to slide laterally, what is the most critical initial step to regain vehicle control?

  1. A
    Activate the auxiliary engine retarder to assist in rapidly decelerating the drive axle.
  2. Stop braking immediately to allow the locked wheels to roll and restore traction.Cevap
  3. C
    Steer firmly in the opposite direction of the rear slide while keeping the brakes pressed.
  4. D
    Maintain heavy braking throughout the slide to bleed off vehicle momentum before steering.

Cevap

Stop braking immediately to allow the locked wheels to roll and restore traction.
In any drive-wheel braking skid, the first and most critical action is to stop braking. Letting up on the brake pedal allows the locked drive wheels to roll again, which restores the friction and lateral grip needed to steer and stabilize the vehicle.

Adım Adım Çözüm

1
Release the service brake pedal immediately upon recognizing the drive-wheel skid.
The drive wheels unlock and resume rolling across the pavement.
Locked wheels slide without directional grip; rolling wheels are necessary to restore traction and directional control.
2
Steer in the direction the rear of the vehicle is sliding, then counter-steer quickly as the vehicle straightens.
The vehicle realigns with the intended lane of travel without snapping into a secondary skid.
Turning into the skid aligns the front and rear axles, while prompt counter-steering prevents overshooting into a skid in the opposite direction.
