What does it mean if a vehicle is equipped with anti-lock brakes (ABS)?

• A. Automatically adjusts tire pressure
• B. Prevents skidding during hard braking
• C. Improves fuel efficiency
• D. Indicates a higher engine power

Answer: (B)

A vehicle equipped with anti-lock brakes (ABS) is designed to prevent skidding during hard braking. The primary function of ABS is to allow drivers to maintain steering control while braking heavily. Under normal braking conditions, when a driver applies the brakes, the wheels can lock up, causing the vehicle to skid. ABS works by automatically modulating the brake pressure, rapidly pulsing the brakes to prevent the wheels from locking. This feature enhances safety, especially on slippery surfaces or in emergency braking situations, allowing a driver to steer the vehicle while braking hard. The other options, while related to vehicle performance and safety, do not accurately describe the purpose of ABS. Adjusting tire pressure, improving fuel efficiency, or indicating engine power do not involve the braking system's function of preventing skidding.
