^^^ if its not an MOT failure, then the Police CANNOT place a prosecution.
Your last statement cannot be a correct.
If the Police say its illegal, and all MOT stations say its totally legal.
Thats almost like being pulled for having a Magic tree air fresher hanging from your rear view mirror, an MOT Failure but the police wouldnt pull you over for it.
Also Since when, unless a copper knows if my car has washers just by looking at it???.
I wouldnt know unless i actually owned one lol.
