What is the purpose of anti-lock brakes (ABS)?

The purpose of anti-lock brakes (ABS) is to prevent wheel lockup during braking. When a driver applies the brakes suddenly, especially on slippery surfaces, there is a risk that the wheels could lock and create a loss of steering control. ABS helps to mitigate this risk by rapidly pulsing the brakes, maintaining the wheels' rotation and allowing the driver to steer the vehicle while braking. This system enhances vehicle stability and control during emergency braking situations, ultimately helping to reduce the likelihood of skidding and collisions. Options that mention enhancing engine performance, improving fuel efficiency, or increasing driving speed do not relate to the function of ABS, as these features focus on different aspects of vehicle operation that do not involve braking control.
