Upon accelerating onto a rain-slicked curved highway ramp, the drive wheels spin and the rear end of the tractor begins sliding toward the outside of the curve. What is the correct procedure to recover from this drive-wheel skid?
- AApply firm service brake pressure immediately while in the curve to abruptly reduce vehicle speed.
- BActivate the engine retarder to provide instant mechanical resistance to the spinning drive wheels.
- Ease off the accelerator, steer in the direction you want the vehicle to go, and counter-steer as the vehicle straightens.Answer
- DTurn the steering wheel sharply away from the direction of the rear slide while maintaining steady throttle pressure.
Answer
Ease off the accelerator, steer in the direction you want the vehicle to go, and counter-steer as the vehicle straightens.
To recover from a drive-wheel acceleration skid, the driver must immediately release the throttle to allow the drive tires to regain rolling traction. The driver must then steer in the direction they want the front of the vehicle to go (steering into the skid) and immediately counter-steer in the opposite direction as the vehicle begins to straighten to prevent a secondary skid.
