Difficulty: EasySkid Control and Recovery

During a drive-wheel skid on a slippery road, pressing firmly on the brake pedal helps the drive wheels regain traction and stops the vehicle from sliding.

Answer: Answer

Answer

False
The statement is false because pressing the brake pedal during a drive-wheel skid locks or over-retards the drive tires, preventing them from rolling and regaining directional grip. Safe recovery requires releasing the brake and accelerator to allow rolling friction to return while steering into the direction of the skid.

Step-by-Step Solution

1
Identify the mechanics of a drive-wheel skid
Drive wheels lose lateral traction when they are locked, over-braked, or spinning.
Vehicle directional control depends on rolling tires generating cornering force.
2
Evaluate the effect of applying firm brake pressure during the skid
Braking locks the drive wheels further, eliminating remaining rolling traction and worsening the slide.
The driver must stop braking and let off the accelerator so the wheels can roll freely and regain grip.
3
Determine the truth value of the statement
The statement claims braking restores traction during a skid, which contradicts CDL safety procedures.
The correct response to the statement is False.
