Inconsiderate parking

Dear parents
It has been brought to our attention that there are parents parking very dangerously particularly at the end of the school day.  We are very aware that parking at the school is limited even in normal times, but we are appealing for you to be considerate to our neighbours. 
We have had reports of parents backing back down the lane and blocking the entrances to the houses. This is not acceptable.  The weather is beautiful this week and we strongly suggest that you park a little further away and walk the last bit to school.  If you are pushed for time, then the breakfast club is free from 8:20 onwards .
Unfortunately, I have no other option than to inform highways and the police so that dangerous parking is stopped before there is an accident.
