POLICE in Avon and Somerset sent a letter warning a speeding driver to slow down on average roughly once every 10 seconds last year.

The force's roads policing unit has revealed that a total of a staggering 64,549 letters were sent to motorists going over the speed limit in the past 12 months.

They were all clocked by community speed watch teams, who do not have the power to prosecute.

The volunteers use radar 'guns' and record the details of vehicles exceeding the speed limit by around 10 per cent.

These details are passed to the police, who will issue a letter to the vehicle owner, advising them of the dangers of speeding, and reminding them of the law.

A social media post from the unit says: "In the last 12 months we've sent 64,549 letters to speeding drivers as a result of Community #SpeedWatch.

"This intel helps inform #RoadsPolicing to target those who pose the greatest risk.

"We're stepping up awareness & intel led enforcement as part of the @PoliceChiefs Speed Op."
