Question

Difficulty: MediumSkid Control and Recovery

When counter-steering to recover from a drive-wheel skid, maintaining the steering wheel turned in the direction of the slide after the vehicle begins to realign will prevent a secondary skid.

Answer: Answer

Answer

False
The statement is false because recovering from a drive-wheel skid is a dynamic two-part steering maneuver. While the driver must initially steer in the direction the rear of the vehicle is sliding, the vehicle will tend to keep rotating as it snaps back on course. Unless the driver turns the steering wheel quickly back the other way (counter-steering back), the vehicle will whip into a secondary skid in the opposite direction.

Step-by-Step Solution

1
Analyze the mechanics of recovering from a drive-wheel skid.
Recognize that the initial recovery action requires steering in the direction the rear of the vehicle is sliding (counter-steering).
Initial steering input aligns the front wheels with the direction of travel to arrest the yaw rotation.
2
Evaluate the behavior of the vehicle as it begins to straighten out.
Identify that the vehicle's momentum will cause it to continue rotating past the center line unless counter-steered back.
Commercial vehicle dynamics require counter-steering back the other way to stabilize the vehicle on its original path.
3
Determine the validity of holding the steering angle after realignment begins.
Holding the steering wheel turned in the direction of the initial skid guarantees a violent overcorrection or secondary skid.
Timely counter-steering in both directions is essential for complete skid recovery.
