What is controlled braking?

Controlled braking refers to the technique of applying the brakes in a manner that maximizes stopping power without causing the wheels to lock up. This method ensures that the driver maintains control of the vehicle while decelerating. When using controlled braking, the driver applies the brakes firmly but feels for the threshold just before wheel lock occurs, allowing for optimal traction and safe stopping.

This technique is important because it enables the bus driver to maintain steering control and stability. By preventing wheel lock, the driver can steer the vehicle to avoid potential obstacles or hazards while slowing down. This is especially critical for school buses, which carry precious cargo—children—who may be highly vulnerable in sudden braking situations.

In contrast, other techniques, such as hard braking that causes wheel lock, do not allow for handling control and can lead to loss of directional stability. Gradually applying brakes to slow down might not provide the immediate stopping power needed in emergencies, and braking only when necessary may not account for the need for smooth deceleration or the potential hazards that require proactive braking.
