Homeowner Nicholas Brooks fears a child could be killed because of inconsiderate parking near De Lacy Primary School in Pontefract.
Dad-of-two Mr Brooks, who lives on School Road just next to the school, says he has spoken to the council and the school to try and resolve the problem.
He said: “Parking is horrendous around school drop-off and pick-up time.
“Despite several meetings and discussions with the council, the school and local councillors, nothing has been done.
“My fear is that it will take someone to be killed or seriously injured before something is done to sort out the problem.”
Mr Brooks said cars park along School Road and the roundabout on Chequerfield Lane at around 8.30am and again at around 3pm.
He added: “The worst bit about it is that most of the parents live a stone’s throw away but they still insist on driving their children to school.
“If an ambulance wanted to get through it wouldn’t be able to and this has been going on for about a year now which is far too long.”
Duncan Thompson, headteacher at De Lacy Primary School, said the school held three walk-to-school initiatives per year to discourage parents from driving their children to school.
He said: “The parking problem is something we are aware of and we’re working with the local police and councillors to sort out the problem.
“We’ve also worked with the road safety team at Wakefield Council to find a solution.
“We are sympathetic towards our neighbours as well because we know they have problems with the parking and we understand that.
“We hope that working together we can sort this out.”
