A crackdown on dangerous driving in Derbyshire saw more than 35 motorists fined or warned in five hours.
Police and road safety officials stopped vehicles on Manchester Road in Glossop.
Offences included 17 people not wearing a seatbelt, 16 drivers using a mobile phone, two cases of illegal parking and one of tailgating.
The Vehicle Operator Services Agency also ordered nine cars to be inspected for road worthiness.
Sgt Barry Doyle said: "People in Glossop have told us that they have concerns about unsafe driving in the area.
"We worked alongside Casualty Reduction and Enforcement Support Team and Vehicle Operator Services Agency to help target their concerns through both enforcement and education, and hope that the checks will also act as a reminder to motorists to be both responsible and safe drivers."
