Police spot check

If any fines were due they would have been issued at the roadside, where the verbal warning has been written this is where the fines would have been if there were any. The piece of paper he gave you is for you to keep for the next 28 days not the office, so that if you are stopped again within 28 days they can see that action has been taken against these two infringements, generally if you’re stopped again in the next 28 days and you show this and are in the same unit they will just give a cursory check
You are told of any action that is to be taken against you at the roadside and a verbal warning counts as action taken, seems your office need to do a CPC or two.
