Children in Chippenham are asking drivers to slow down so they feel safe walking to and from school.
A poster campaign aiming to reduce speeding around Pewsham is to be launched in September.
Abbeyfield secondary school and Charter and King’s Lodge primary schools took part in a competition to design the poster.
Winners, Ellie Purdy, nine, from King’s Lodge and Kya Heathcote, seven, from Charter, will have their work displayed on a banner hanging across the High Street, as well as on posters at all routes to Pewsham schools.
Wiltshire councillor Bill Douglas, who organised the campaign, said: “We hope the children of the area will advise their parents to pay attention and drive carefully.
“The campaign will remain in force in the community for three months and if it’s successful we will move it to five different areas in Chippenham in sequence.”
The No Need For Speed campaign cost £2,500 and is being funded by Wiltshire Council’s Chippenham Area Board.
