Increase speed
Prevent wheel lockup
Enhance fuel efficiency
Improve comfort

The correct answer is: Prevent wheel lockup

The main purpose of anti-lock braking systems (ABS) in trucks is to prevent wheel lockup during braking. When a driver applies the brakes hard, especially in slippery conditions, the wheels can lock up, causing the vehicle to skid and lose control. ABS works by automatically modulating brake pressure to ensure that the wheels continue to rotate, allowing the driver to maintain steering control while still slowing the vehicle effectively. This technology is crucial for enhancing vehicle safety, particularly in adverse weather conditions or during emergency stops. By preventing wheel lockup, ABS allows for a better grip on the road and reduces stopping distances, which can significantly lower the risk of accidents. Therefore, the correct understanding of ABS is centered on its function in maintaining wheel rotation during braking, enhancing overall vehicle control and safety.
