At what distance should a bus signal for an exit off a highway?

A bus should signal for an exit off a highway at a distance of 250 feet. This distance is important for ensuring safety and efficiency when maneuvering the vehicle. Signaling at this distance provides adequate warning to other drivers and ensures that the bus has enough time to safely change lanes and prepare to make the exit. It gives approaching vehicles enough time to react if necessary, while also adhering to standard signaling practices that promote orderly traffic flow. This distance helps prevent potential accidents and ensures that all road users are aware of the bus's intentions well in advance.
