Question

Difficulty: HardWinter Driving, Snow, and Black Ice

If a vehicle equipped with an Anti-Lock Braking System (ABS) begins to skid on a bridge deck covered with black ice, the driver should rapidly pump the brake pedal to prevent wheel lockup and regain directional control.

Answer: Answer

Answer

The statement is False. Drivers operating vehicles equipped with ABS must maintain firm, continuous brake pressure rather than pumping the brakes when attempting to slow down or regain control on slippery surfaces like black ice.
The statement is false because modern Anti-Lock Braking Systems (ABS) are engineered to modulate brake pressure automatically at high speed. Pumping the brake pedal manually prevents the ABS system from functioning properly. On slippery surfaces like black ice or packed snow, the driver must ease off the accelerator, look and steer in the direction they want the vehicle to go, and hold the brake pedal down firmly if braking is required.

Step-by-Step Solution

1
Identify the brake system technology specified in the scenario
The vehicle uses an Anti-Lock Braking System (ABS).
Correct braking technique during winter driving hazards depends directly on whether the vehicle features ABS or conventional non-ABS brakes.
2
Analyze standard ABS operation on icy road surfaces
ABS automatically pumps the brakes dozens of times per second when traction loss is detected.
Electronic sensors automatically prevent wheel lockup while maintaining steering capability.
3
Determine correct driver action during a skid on black ice
The driver should ease off the accelerator, steer in the direction of the skid, and apply firm, continuous pressure to the brake pedal if braking is necessary.
Manually pumping an ABS pedal prevents the system's sensors and computer from operating effectively.
