Motorway Cops: Catching Britain's Speeders

Nicky Campbell narrates a look at how the nation's roads are policed, joining Cheshire's elite team of motorway officers as they crack down on Britain's worst drivers. In the opening edition, Amy Hollis is on the hunt for a drunk driver who has been on a late-night wrecking spree through the streets of Chester, leaving a trail of damage to parked cars.

Officer Matt Turner brings a car to a stop in the middle of the motorway, coming across an unexpected haul as well as a surprising passenger who stops him in his tracks. On a night shift, Niaz Waddington encounters a driver with no lights on and it quickly becomes clear the motorist has been drinking.

A suspected drug dealer has an unusual explanation for the suspicious contents of his car - but an even bigger surprise faces the police when they also search his home. Chris Swash is on the trail of a dangerous driver, PC Amy Hollis stops a late-night motorist running red lights in the town centre, and two drivers clash after a collision.
