6x3 - Motorway Cops: Catching Britain's Speeders

PC Will Hunter pursues a car suspected of having cloned plates and when the driver eventually pulls over, the officer finds the driver aggressive, argumentative and smelling of alcohol, as well as unwilling to do a roadside breath test. In Northumberland, PC Chris Kemp is trying to find a car that refused to stop from motorway cops the previous night and tracks it down, but as soon as the occupants spot him they race off.
