Nearly 50 drivers were found not to be wearing a seatbelt during a crackdown on unsafe driving in Buxton.
Derbyshire Constabulary, the Casualty Reduction and Enforcement Support Team and the Vehicle and Operator Services Agency stopped more than 100 drivers on the A6 on Friday.
A staggering 47 motorists were found not to be wearing a seatbelt, 14 people were seen to be using a mobile phone at the wheel and 11 vehicles were stopped for registration plate offences.
Nine vehicles were seized as they had serious defects.
And 20 warnings and penalties were issued to motorists for a number of offences including driving without a valid licence, defective tyres, faulty lights, insecure loads and driving without a current MOT.
Sergeant Denis Murphy, of Derbyshire police, said: “I am always surprised at the number of people who choose not to wear seatbelts while driving, despite the hard-hitting publicity campaigns since the law was changed several decades ago.
“I am also disappointed that people continue to use handheld devices at the wheel, despite all the evidence that suggests that this is one of the more common causes of more serious collisions.
“Reducing casualties on the roads remains a priority for the force and we will continue to work with the communities of Buxton and the motoring public through this and similar operations.”
The crackdown was part of Operation Safedrive, an ongoing Derbyshire police campaign to educate motorists about responsible driving and make the county’s roads safer.
