When should bus drivers cancel their turn signal during a lane change?

The appropriate time for bus drivers to cancel their turn signal during a lane change is when the maneuver is complete. This is critical for ensuring safety on the road. By allowing the signal to remain on until the lane change is fully executed, it provides clear communication to other drivers about the bus's intentions. This reduces confusion and helps prevent accidents.

Cancelling the signal too early, such as before starting the lane change or as soon as beginning it, could mislead other drivers about your actions. It is vital that the signal indicates the full procedure, from the initiation of the lane change until it is safely completed. This practice aligns with safe driving standards and helps maintain proper traffic flow, particularly in a vehicle as large as a bus, where visibility and communication are even more essential.
