A commercial motor vehicle driver encounters sudden icy road conditions and the rear drive wheels begin sliding sideways. What is the correct sequence of actions the driver must take to safely recover control? Arrange the following recovery steps in chronological order from first to last.
- 1Immediately release the accelerator pedal to eliminate drive torque and allow the drive tires to resume rolling.
- 2Depress the clutch pedal to completely disconnect the driveline and prevent engine drag or stalling.
- 3Turn the steering wheel toward the direction of the skid to guide the front of the vehicle back into alignment.
- 4Counter-steer in the opposite direction as the vehicle begins to straighten out to prevent overcorrecting into a secondary skid.
Cevap
The correct sequence is: (1) release the accelerator pedal, (2) depress the clutch pedal, (3) steer into the direction of the skid, and (4) counter-steer in the opposite direction as alignment begins.
Recovering from a drive-wheel skid follows a precise four-stage protocol: first, release the accelerator to stop drive wheel spin; second, depress the clutch to remove driveline drag; third, steer in the direction of the skid to realign the tractor; and fourth, counter-steer in the opposite direction the moment the vehicle begins to straighten to neutralize rotational momentum and prevent a secondary skid.
Adım Adım Çözüm
Anahtar Kavram
Drive-wheel skid recovery requires immediate throttle release, clutch disengagement, steering into the skid, and counter-steering to prevent secondary skidding.
