when do you not need to stop if a school bus is loading or unloading
School bus traffic stop laws Generally, if a stopped school bus is displaying a flashing, alternating red lamp, a driver of a vehicle meeting or overtaking the stopped bus from either direction (front or back) must stop and wait until the bus moves again or the red light is off.[1] Police officers, school crossing guards, and even school bus drivers themselves may have the power to wave traffic on, even when a red light is flashing.
School bus yellow School bus yellow is a color which was especially formulated for use on school buses in North America in 1939. The color is now officially known in Canada and the U.S. as National School Bus Glossy Yellow and was originally called National School Bus Chrome. The pigment used for this color was, for a long time, the lead-containing chrome yellow.[1]
