Question

Difficulty: EasyBraking Systems and ABS

An Anti-lock Braking System (ABS) guarantees a shorter stopping distance on every type of road surface, including loose gravel and deep snow.

Answer: Answer

Answer

False
The statement is false. The main function of ABS is to allow the driver to maintain steering control during heavy braking by preventing the wheels from locking. On loose surfaces such as snow, ice, or loose gravel, an ABS-equipped vehicle may actually require a greater stopping distance than a vehicle with locked wheels.

Step-by-Step Solution

1
Identify the primary purpose of an Anti-lock Braking System (ABS).
ABS is designed to prevent wheels from locking during emergency braking, enabling the driver to retain steering control.
Understanding the fundamental objective of ABS distinguishes steering control from stopping distance reduction.
2
Assess how ABS performs on loose road surfaces such as gravel or snow.
On loose surfaces, preventing wheel lock prevents the formation of a wedge of surface material in front of the tyres, which can lengthen the distance required to stop.
This confirms that ABS does not guarantee shorter stopping distances in every condition.
