While school buses are one of the safest vehicles on the road, others must obey a bus’s signs as well as laws related to schools buses. School buses stand out from other vehicles on the road, providing enhanced safety features such as a bright exterior, flashing lights and stop signs. School buses signal to drivers when to stop or prepare to stop. Yellow flashing lights indicate the bus is preparing to stop to load or unload passengers. Red flashing lights and deployed stop signs signal for all vehicles to stop. Passing a stopped school bus can result in serious fines, injuries or death, so it’s imperative for everyone’s safety that drivers obey a bus’s lights and signs.
