A school or kindergarten bus must switch on its hazard warning lights while it is stopped to let children get on or off.

Explanation

This matches the law. When a school/kindergarten bus is stopped so that children can board or get off, turning on the hazard warning lights is a duty, not an option. The flashing lights warn other drivers that children may be around the bus.
