Question

Difficulty: MediumSkid Control and Recovery

During recovery from a drive-wheel skid, counter-steering back in the opposite direction as the vehicle aligns with the intended path of travel is required to prevent a secondary skid in the opposite direction.

Answer: Answer

Answer

True
The statement is true because commercial vehicles possess substantial rotational inertia during a drive-wheel skid. As the vehicle comes back on course, the driver must immediately counter-steer in the opposite direction to prevent the rear end from swinging past center and causing a secondary skid.

Step-by-Step Solution

1
Analyze the mechanics of initial drive-wheel skid recovery.
Steering in the direction of the rear-wheel slide aligns the front wheels with the vehicle's momentum to regain directional control.
Turning into the skid counters the initial yaw rotation of the vehicle.
2
Evaluate rotational momentum as the vehicle straightens on course.
The straightening vehicle has kinetic momentum that tends to continue rotating past the desired travel path.
Without rapid counter-steering back the other way, the vehicle overcorrects and enters an immediate secondary skid in the opposite direction.
