Motorway Cops: Catching Britain's Speeders - Season 7 Episode 4 -

It's a wild night on Newcastle's roads. PCs Jamie Leslie and Máire Curran stop a teen drink-driver after a party. In the West End, a driver with no licence, no insurance-and cannabis in his system-barely reacts when pulled over. Meanwhile in Sunderland, PC Martain Anderson races to a crash involving a motorbike and a car. Dashcam footage may reveal what really happened.
