Dd's entrance to her primary school is on a very tight corner of the road in a residential estate, there are of course zig-zag lines outside the school entrance, however everyone parks on them, we have to walk all the way up the road just to be able to cross the road safely. A few of the teachers leave at the same time as school finishes and they never say anything to the parents parked on them, so i am just wondering if they are there just as a precautionary measure??
