School buses are equipped with flashing red lights that are activated by the driver when loading or unloading pupils. California law requires that drivers approaching from either side of the bus must stop and remain stopped while the red lights and stop arms are activated. The only exceptions to the law come into play when the bus is stopped on a roadway with multiple lanes and a divided highway or a raised center divider. If you are approaching from the opposite direction and on the opposite side of the road from the bus on a divided highway, you may proceed. This section, CVC 22454, also applies to private roads.
