Motorists were caught for various motoring offences in a day-long operation held in Ely.
Officers were stood just from Ely Police Station with drivers pulled straight from the road into the station.
A total of 37 tickets were issued for no seat belts while 14 tickets for mobile phone offences were issued in just a total of 4 hours.
Among those caught was a motorist who, besides not wearing his seatbelt, also decided to start a drag race at the traffic lights just 100 yards from waiting officers.
He was handed a fixed penalty notice and issued with a section 59 order.
