A signal assembly has a handle that a person can move up and down, causing one or more reflective surfaces to be shown and hidden (flash) to alert a bus driver of a passenger's presence at a bus stop. The signal assembly may, for example, mount on a bus stop sign or a bus stop shelter. The flashing reflective surface may receive an oncoming bus' headlights and reflect the light to alert the driver. When the handle is not moved up and down, a reflective surface of the signal assembly may still be visible to the bus driver, alerting the bus driver of the presence of the stop. A driver who is not familiar with the route may find this useful, especially when a passenger indicates a request for the bus to stop at the next stop.
