What is ABS in braking systems?

The correct choice indicates that ABS stands for Anti-lock Braking System. This system is a vital safety feature in modern vehicles, including those equipped for towing heavy trailers. The primary function of ABS is to prevent the wheels from locking up during hard braking. When a driver applies the brakes forcefully, the anti-lock system modulates brake pressure to ensure that the wheels can continue to rotate, allowing the driver to maintain steering control while stopping.

This technology is especially significant when handling heavier loads, as in the case of trailers, where maintaining control during sudden stops is critical for safety. By preventing wheel lock-up, ABS reduces the chances of skidding and enhances overall vehicle stability and control during emergency braking scenarios. This capability is essential for drivers who need to manage the added weight and dynamics of towing, particularly under varied road conditions.
