PC Sara Sumner and PCSO Jacqui Tudor of the Neston police team launched a competition last year to involve pupils in the quest for safer parking outside Woodfall Primary School.
PC Sumner said: “It was brought to the attention of Cheshire police that there are some local areas that suffer from regular parking and congestion problems at school dropping off/picking up times.
“To try and educate those people causing the issues when parking, we have involved children by asking them to design a poster based around more considerate, safer parking.”
The first school to take part has been Woodfall Primary in Little Neston.
Prizes for the best poster and runner-up were sponsored by Project Rural Matters.
PCSO Tudor presented winner Eliza Dowling and runner-up Sam Munday, both in Year 4, with their prizes of Argos vouchers at assembly.
Junior road safety officers and school staff will now be keeping a close eye on cars parked inconsiderately outside the school.
Small versions of the posters will be left on cars that are thought to be flouting the safety code.
Copies of the designs are now being sent home to parents, with a dire warning: that if they find one of these on their windscreen any time soon, they will be in trouble for ‘naughty parking’!
