Community Speed Watch volunteers and police have been carrying out checks in Bradwell and Curbar.
Officers from the Hathersage Safer Neighbourhood Policing Team (SNT) joined the volunteers for checks on Stretfield Road, Bradwell and The Bent, Curbar.
A total of 16 motorists were caught travelling above the 40mph limit during the two checks in Bradwell on Wednesday, July 11 and Wednesday, July 18.
Community Speed Watch was set up to target residents concerns about issues with speeding and to give people a chance to work alongside officers on road safety issues.
Any drivers caught breaking the limit are sent a letter to inform them about the check, to raise awareness of the local limits and that if they continue to speed, they risk a fine and penalty points on their driving licence.
Data which is recorded through the scheme may also help officers to identify locations for future speed enforcement checks.
The scheme has been running in the Hathersage area since November 2010.
