On patrol in Derbyshire, the traffic cops tackle a variety of criminals, ranging from drunk or drugged drivers to violent county lines drug dealers and organised crime gangs.

As part of Project Edward - a week-long nationwide crackdown on illegal drivers - Derbyshire's traffic cops set up check-sites across the county. PC Andy Swift and PC Stu Smith pull over a car at one stop and the driver eventually pulls out a knife, forcing the officers to draw their Tasers and restrain the man. PC Jason Potts and Sgt Scott Riley go to investigate when a van crashes at night near a check-site, finding the vehicle on its roof in the bushes, but with no sign of the driver.
