A school bus stops ahead at a point where you might not expect one

Ease off and be ready for a stopped bus and children close to the road

A school bus picking up or setting down just ahead, at a spot you would not see in time

The sign goes up where a bus stops over a crest, round a bend, or somewhere else that gives a following driver no warning. It is telling you to come off the accelerator now, so a stopped bus with its lights flashing is not a surprise. Children around a bus cross in front of it, where the driver behind cannot see them at all.

You have passed this sign on a two lane road and now see a school bus ahead with its upper red lights flashing. What must you do?

Stop well back and wait until the lights stop flashing and the bus moves
