A school bus is painted National School Bus Glossy Yellow in the United States and similarly in Canada. The color now officially known in the U.S. as National School Bus Glossy Yellow was originally called National School Bus Chrome.
Signs in the front and rear top center read SCHOOL BUS or AUTOBUS SCOLAIRE or ECOLIERS in French in parts of Canada. Each of its front and rear ends usually has alternately flashing lights with 2 red lamps at top corners and 2 yellow (amber) lamps near red lamps at the same level but closer to the vertical central line of the bus. It often has an octagon red stop arm on the left side.
Schools OPEN – drive carefully!
