The Official Ministry of Transportation (MTO) Driver's Handbook identifies – You must stop whenever you approach a stopped school bus with its upper alternating red lights flashing, regardless of whether you are behind the bus or approaching it from the front.
- When approaching the bus from the front, stop at a safe distance for children to get off the bus and cross the road in front of you.
- If you are approaching from behind the bus, stop at least 20 metres away.
- Do not go until the bus moves or the lights have stopped flashing.
- These rules apply regardless of the posted speed limit and apply to highways, country roads, and city, town and village streets.
