Hi guys,
Does anyone know of any rules around unmarked police cars? There seems to be at least one a day that I see going up and down of the M4 near Reading on my commute. They don't have "Police" in the rear window flashing and they're always various makes of cars.
They just seem odd. One passed me before and then switched the lights off when they got through the traffic. Makes me wonder if it is people kitting out their cars and pretending to get through traffic.
