A swoop on the so-called 'fatal four' causes of car crashes netted more than two dozen offenders yesterday.
Police were out in force on the busy A30 near Okehampton to stage their road safety campaign. The day of action was organised after North and West Devon were the scenes of a number of collisions which left people dead or seriously injured.
Inspector Andy Oliver, from West Devon, said the operation had aimed to crack down on the 'fatal four': speeding, using a mobile phone while driving, drink-driving and failure to wear a seat belt.
"This policing operation is in direct response to concerns over the number of fatal and serious injury collisions in the area," he said.
"Road users expect to be able to travel safely on our roads. This highly visible operation seeks to deter and detect offences and address driver behaviour which, from experience, may otherwise lead to serious collisions."
During the four-hour operation, a total of 25 offences were detected, inluding 15 of failure to wear a seat belt, seven of using a mobile phone while driving, two of driving through a red light and one relating to poor condition of a vehicle.
Insp Oliver added: "This is one of a series of operations planned throughout North and West Devon over the coming months."
He said police and the Highways Agency would be working to encourage drivers to reduce their speed when towing trailers or caravans at Sourton, west of Okehampton, where he said collisions "have been occurring almost weekly in previous years".
