What is the function of anti-lock brakes in a school bus?

The function of anti-lock brakes (ABS) in a school bus is to prevent the wheels from locking during hard braking. This is crucial for maintaining steering control and stability while braking, especially in emergency situations or when road conditions are less than ideal. When a driver applies the brakes forcefully, the ABS system automatically modulates brake pressure to ensure that the wheels continue to rotate rather than skid. This allows the driver to maintain better control over the vehicle and navigate safely even in a panic stop scenario.

The effectiveness of ABS is particularly vital in larger vehicles like school buses, which can have a longer stopping distance due to their size and weight. By preventing wheel lock-up, the ABS helps to reduce the risk of skidding and improves overall safety for both the driver and passengers.
