Drugs and drug driving have become a major challenge for North Yorkshire's traffic cops. Last year, police made nearly 200,000 drugs seizures in England and Wales. In North Yorkshire, seizures were at a ten-year high. In this episode, whilst North Yorkshire's specialist road crime team targets drug deals in transit, a full-scale investigation unfolds in the aftermath of a high-speed crash on one of the county's fast rural dual carriageways. It becomes clear that speed may not have been the only contributory factor to the crash, which resulted in the death of the driver. Dealing with the aftermath of the tragedy left behind by drivers too drugged to drive has become all part of the traffic cops' daily routine.
