Children from two Sutton primary schools laid down the law as traffic police stepped aside for them to help promote speed awareness across the borough.

Pupils from Foresters Primary School and Robin Hood Juniors participated in the first of two Junior Roadwatch activities this year, part of a safety campaign.

Speeding drivers caught by the keen-eyed schoolchildren had the option of either being fined or getting a speed awareness lecture from the wannabe law enforcers.

Tarik, who is in Year 6 at Robin Hood Juniors, said: “I found it really exciting – it was so much fun to work with the police. I think one day I would like to be a detective!”

Eight vehicles were stopped in Foresters Drive, the fastest being at 35mph, while on Throwley Road a vehicle was recorded at 43mph and stopped by police.

A further roadwatch also took place at Foresters Drive, which was supported by school pupils from nearby Foresters Primary School.

Miss Trumper, head of Year 6 at Robin Hood Juniors, said: “This was such a beneficial activity, not only for the pupils but also for the motorists who were questioned.

“It was evident from the motorists’ reactions to the children’s questions that they hadn’t fully appreciated what the possible outcome could have been from their speeding.

“This is something that I would do again with my pupils.”

Cllr Marian James, chair of Sutton Council’s people committee, believes the initiative is a “great example” of delivering on “Keeping People Safe” commitments to safeguarding children in and around schools.

She added: “Thanks to our partners across police, schools and TfL [Transport for London] for continuing this very worthwhile activity.”
