What is the function of anti-lock braking systems (ABS) in vehicles?

• A. To reduce headlight intensity
• B. To prevent wheel lock-up during hard braking
• C. To enhance fuel efficiency
• D. To increase engine power

Answer: (B)

The function of anti-lock braking systems (ABS) in vehicles is to prevent wheel lock-up during hard braking. When a driver applies the brakes forcefully, especially in slippery conditions, the wheels can lock up, leading to loss of steering control. ABS quickly modulates the brake pressure to ensure that the wheels do not completely stop rotating. This allows the driver to maintain steering control while braking hard, which is crucial for avoiding obstacles and maintaining vehicle stability. The system works by using sensors to monitor wheel speed and a control unit to adjust braking force accordingly, enhancing safety during emergency braking situations.
