Pupils at Kirkfieldbank Primary School showed the red card to motorists driving too fast through their village.
The pupils were receiving a special road safety training session from the Lanark area’s two Problem Solving Officers, Constables Dougie Cowan and Melitta Pllu, accompanied by local councillor Julia Marrs, chair of road safety on South Lanarkshire Council.
And during it, the officers invited the youngsters to join them on the kerbside to check on the speed of passing motorists.
The pupils had prepared green and red signs with slogans and images to hold up as motorists passed, reflecting the appropriateness of their speed.
Despite the drizzle, 14 pupils enjoyed their chance to influence the behaviour of passing motorists and put their recent learning about road safety into practice.
Thanking the police officers for taking their time to work with the children, Julia, who has three children at the school, added: “I was very pleased to see that road safety is clearly a priority for the school, and to see how much the children enjoyed the session.
“I am hopeful that new speed detection equipment that the police will soon be using will further deter drivers who behave irresponsibly, especially near schools.”
