When maneuvering a turn, how must a school bus signal its turn?

When maneuvering a turn, a school bus is required to signal its intention to turn with a turn signal. This is essential for ensuring safety on the road, as using a turn signal communicates to other drivers and pedestrians that the bus is about to change direction. The turn signal allows for clear and consistent communication among all road users, which is especially important in a school environment where children may be present.

Turn signals are standardized indicators that provide visual cues, thereby minimizing the risk of accidents caused by sudden movements or turns. Proper signaling helps maintain orderly traffic flow and enhances overall road safety.

Other signaling methods, such as using a horn, continuous lights, or hand signals, are not considered standard or reliable for indicating a turn in a bus. Horns are typically reserved for alerting others to an immediate danger rather than signaling a change in direction. Continuous lights might confuse other drivers, as they do not indicate a specific movement. Hand signals can be difficult for other road users to see, especially at a distance or in adverse weather conditions. Therefore, using turn signals is the established and efficient method for indicating turns, especially in the context of operating a school bus.
