Motorway Cops: Catching Britain's Speeders

Following motorway officers as they crack down on the nation's worst drivers. In Stoke, PC Chris Bagnall pursues an illegal off-road biker who rides dangerously through side streets and against traffic. When another patrol spots a dodgy rider, Chris goes on the hunt. Also, a car has crashed into the barrier on the M6, with the driver blaming her lane assist.

PCs Tom Cordall and Greg Chadwick track an Audi A3, which has been reported stolen, on the M6. Rolling roadblock tactics are put in place, to bring traffic to a standstill and box the suspect vehicle in. On the nightshift, PCs Ed Clarke and Elly Martin are patrolling when a Mercedes flies past them, with the speedy driver clocking in at 110mph and counting.

In Cannock, PC Ade Cash joins the hunt for a Mondeo that's failed to stop for police. When another unit gets behind it, the driver makes off - reaching speeds of 80mph in a 60 zone and crashing into other motorists. On the M6, PC Mark Gribble is training PC Aaron Hardy in the art of spotting dodgy drivers. Aaron clocks a dog in the driver's seat - a first even for Mark.

Late at night, PCs Chris Bagnall and Tom Cordall respond to reports of a hit and run - a suspected drink driver in a Land Rover has driven over a pedestrian and made off. Patrolling the M6, PC Elly Martin is left in the dust by a speeding Audi. The driver's doing over 90 as Elly gets on his tail. ANPR alerts Chris and Tom to a Seat Ibiza near Wolverhampton linked to drug dealing.

A provisional licence holder in a Seat Ibiza has failed to stop for police on the M6, hitting speeds of 100mph. PC Ben Edwards races to catch up and join more patrols in using tactics to get the driver stopped. PCs Mark Gribble and Lucy Pond are on motorway patrol when they spot a flatbed truck missing a wing mirror and, it turns out, an MOT.
