Twelve motorists clocked breaking the speed limit in Derbyshire will receive warning letters.
The drivers were caught by community speed watch volunteers in Hathersage and Bradwell.
The letters will tell them what the local speed limits are and warn them if they continue to speed, they risk a fine and penalty points.
There are 19 trained community speed watch volunteers and patrols have been carried out in Calver, Stoney Middleton and Grindleford.
A total of 153 letters have been issued since the scheme was launched in 2010.
PCSO Anthony Boswell, of the Hathersage Area Safer Neighbourhood Policing Team, said: “Community Speed Watch is continuing to work well, raising awareness about local speed limits and residents’ concerns and most importantly encouraging motorists to drive safely.
“A big thank you to all the volunteers who give up their time to help carry out checks and do something positive for their community.”
Volunteers spent time checking traffic in two-hour-long sessions on Church Street, Bradwell and Castleton Road, Hathersage.
Data which is recorded through the scheme could be used in future to help officers to identify locations for speed enforcement checks.
Community Speed Watch was introduced in November.
