Georgia DDA 6-Hour Defensive Driver & Driver Improvement Practice Exam

The primary purpose of the Anti-lock Braking System (ABS) in vehicles is to prevent the wheels from locking up during braking. When a driver applies the brakes forcefully, there is a risk that the wheels may stop rotating, which can lead to a loss of steering control and increased stopping distances. ABS helps maintain steering control in such situations by modulating brake pressure. This allows the wheels to continue rotating, which helps maintain traction and enables the driver to steer the vehicle as needed. While some may consider the other options, they do not represent the main function of ABS. For instance, ABS does not serve as a warning system for brake failure, nor is it specifically designed to prolong the lifespan of brake pads and fluid. Its core objective is enhancing vehicle safety by preventing wheel lock-up during emergency braking situations, thus making option A the correct answer.
