I can remember back when we were in primary school a police officer used to come into each classroom to teach us the rules of crossing the road i.e. when we wanted to cross over the road we must, look to the right, then look to the left, then look to the right again and then when it was safe hurry across but don't run. He also told us about "stranger danger". I don't think this is taught in schools today. It was drummed into our heads, and I never forgot it and taught it to my boys when they attended school.
