More than 1,000 children could be put at risk after the sudden departure of a lollipop man from one of the county's busiest roads.
Teachers at Myton School are having to control pupils as they cross Myton Road following the retirement through ill health last week of the man who had patrolled the crossing for 20 years.
One fearful parent believes "there will certainly be an ac
cident" in the road - which last month had its speed limit reduced to 30 mph due to concerns about the dangers of high-speed driving.
Headteacher Geoff Walker was troubled after learning that secondary schools do not automatically qualify for lollipop patrols.
He said: "We're quite concerned as it's a dangerous road and we do need a lollipop man or lady.
"There have been no incidents at the school but the possibility is very worrying.
"We urgently want a replacement, for whom we will have to pay for ourselves - which I am very happy to do."
One parent, who wished to be known only as Elizabeth and has two pupils at the school, said: "I saw four teachers trying to control kids who were coming out of school and running across the road, which I think is an accident black spot.
"It was horrendous and horrific.
"In the mornings no teachers are there.
"There is absolutely no-one and there will certainly be an accident."
The school's lollipop man, who had been helping children cross the road for more than 20 years, had to retire suddenly due to health reasons.
Warwickshire County Council - the local authority responsible for schools - has begun talks with Myton School, which is attended by 1,601 pupils, to try to resolve the issue.
Senior road safety officer Stan Milewski said: "Interviews for a new school crossing patrol have taken place and we are hoping to have one start work in the next week or so.
"While county council policy is not to provide school crossing patrols to senior schools, we are happy to provide advice on road safety to all secondary schools and work in partnership when headteachers feel it is appropriate.
"However, recruitment for school crossing patrol is getting harder and therefore our priority is heavily focused on the provision for primary schools."
