The police forces in England have, for some time had Automatic Number Plates Recognition System cameras at their disposal but until recently had not realised just how widespread the problem of uninsured drivers was ( some estimates put it as high as 2 million ) and just how effective the ANPR system can be in detecting these law breakers. London police have been engaged in operation Reclaim since the end of 2007 and have been surprised at the high number of expensive cars they have seized due to them not being insured. The trigger for the increase in ANPRS policing has come from a recent change in legislation which allows a beat officer to impound a vehicle whereas previously this was the duty of a specialised traffic officer whose time could better be spent on more serious offences.
