When I became a police officer, after the weeks at training school, if you got through, one was posted in my force to a largish town. There you were attached to a tutor constable, who was lumbered with you until he/she and the sgt were happy for you to go it alone. In my 2 yrs probation which EVERY copper had to do,,tyres, number plates, silencers, lights etc were the bread and butter jobs for the proby.
A system was introduced to save time and that was the VDRS ( vehicle defect rectification scheme) which was a pretty good idea. Basically, if you stopped/found a motorist with say a headlight out. A VDRS was issued. The motorist then had the problem rectified and for £10 at an MOT station got the VDRS stamped as done. If the person failed to do the work, it was straight to court. It worked very well as it not only freed up a lot of time it got all the things like number plate spacing, light defects minor tyre transgressions etc sorted. It also picked up a considerable number of document offences, which now are checked on line. Clearly this scheme has long gone given the number of one eyed monsters on the road. It literally only took a few minutes to write a VDRS up. Modern coppers reckon they have no time so consequently the motorist is literally getting away with murder.
