Few traffic rules matter more than this one. Here is exactly when you must stop for a school bus in Ontario, and what happens if you don't.

When a school bus has its overhead red lights flashing and its stop arm out, Ontario's Highway Traffic Act requires drivers coming from either direction to stop. The only exception is a road divided by a median, where only traffic behind the bus must stop.

Stop well back from the bus, at least 20 metres if you are behind it, and stay stopped until the lights stop flashing. A first offence carries a heavy fine and 6 demerit points.
