What is the function of the Anti-lock Braking System (ABS)?

The function of the Anti-lock Braking System (ABS) is to prevent the wheels from locking up during hard braking. When a driver applies the brakes forcefully, there's a risk that the wheels may stop rotating entirely, which can lead to a loss of steering control. ABS helps to avoid this situation by automatically modulating brake pressure, allowing the wheels to continue rotating and maintaining traction with the road. This means that the driver can maintain steering control while braking hard, which is crucial in emergency situations where avoiding obstacles is necessary.

The other options do not describe the primary function of ABS. For instance, increasing fuel efficiency, enhancing acceleration, and improving steering response are not the main goals of this system; instead, all of these aspects are typically influenced by other vehicle technologies or driving practices. The primary purpose of ABS is focused on safety by maintaining traction and control during braking, particularly in adverse conditions.
