When should light pressure braking be used?

Answer: C — On wet or icy surfaces

Light pressure braking is essential on wet or icy surfaces to maintain control of the vehicle while reducing the risk of skidding. When road conditions are slippery, using too much brake pressure can cause the wheels to lock up, leading to loss of traction and control. By applying light pressure to the brake pedal, a driver can slow down the bus gradually and safely, allowing for better handling and stability during the braking process. Using light pressure braking helps ensure that the wheels continue to turn, which is crucial for maintaining steering control, especially on surfaces that might otherwise cause hydroplaning or sliding. This technique allows the vehicle to decelerate without compromising safety or maneuverability, making it a vital practice in inclement weather conditions.
