When a bus is stopped for loading or unloading passengers, it is essential to activate the hazard lights. This action serves several vital functions: it signals to other drivers that the bus is stationary and that there may be pedestrians or passengers entering or exiting the vehicle. Activating hazard lights enhances visibility and alerts surrounding traffic to proceed with caution.

Using hazard lights indicates that the bus is not moving, and it provides a clear warning that drivers should be on the lookout for potential hazards, such as children crossing the street or boarding the bus. This is particularly important in school zones or areas where passengers might be getting on or off.

While headlights, brake lights, and turn signal lights can be used in certain driving conditions, they do not convey the same clear message as hazard lights in this specific situation. Headlights are primarily for visibility, brake lights indicate stopping, and turn signals indicate directional changes, none of which sufficiently communicate the need for caution around a stationary bus engaged in passenger loading or unloading. Therefore, activating hazard lights is the appropriate and best practice to ensure safety.
