Youngsters have launched a campaign for a crossing outside their school to help them get to class safely.
Year 6 pupils at Brockswood Primary School have taken up the cause as part of classroom work to look at a local issue that affects their environment.
They arrived at school, in Shenley Road, early on one day to stand outside the school in high vis jackets and collect signatures for their petition, which will be handed over to County Hall officials.
Maths teacher Annie Swan said: “They all came in early - by 8.10am - and they had written the petition themselves and they decided what they wanted to say to get the signatures.
“There is absolutely nothing out there for the children and it is a really busy road.”
The school is hoping for a zebra crossing or a lollipop patrol, both traffic measures come under the power of Herts County Council.
Pupils will be writing to the council and also enlisting the help of Councillor Rosie Sutton, who is also on the school’s governing body.
