Sixty-five vehicles were stopped in Halifax during a clampdown by police and supporting agencies.
The Vehicle and Operator Services Agency and HM Revenue and Customs also took part in the exercise at Salterhebble Hill and Boothtown Road.
The day was aimed at cracking down on metal theft, theft from motor vehicles and traffic offences.
Officers checked a number of vehicles and one vehicle was seized for no insurance; 2 drivers were reported for not having a licence/insurance; one was given a fixed notice for no MoT and another for having a faulty registration plate.
Sgt Warren Pitman from Halifax Central NPT, said: “The day was all about having a visible presence in the area so motorists trying to break the law knew they had nowhere to hide.
“It was important to work with our partners to ensure we could make a real impact.
“We also offered crime prevention advice.”
