Road Wars (2003)

Season 5: Episode 9

Ronnie and Roma, out on patrol in Slough, when they pass a car whose occupant hastily hides something. He claims he’s had nothing to drink, despite having booze breath and a can sitting provocatively in the passenger footwell. The car may not be moving, but the keys are in the ignition so, in legal terms, he’s in charge of the car. Once back at the nick, however, the reading on the intoximeter causes jaws to drop in astonishment!
