A practice that was occasionally talked about in police canteens was the game of snooker, not table snooker but "traffic snooker". This was a game specifically played by lads in the traffic division, the dreaded speed cops whose main work consisted of dealing with traffic accidents but who also reported motorists for speeding offences. The game the officers played consisted of scoring points, as in table snooker, the numbers depending on the colours of the cars they had reported for speeding during their shift — for example, a red car scored 1 point, a yellow 2 points, and so on, with a black one scoring the maximum 7 points. At the end of a shift, the traffic cars on the division would return to the police garage and the crews totted up their points to find the winner. I never heard what the prize was.
