Forensics: Crash Scene Investigators (2025- )

In the Yorkshire Dales, a car with 5 young soldiers onboard has crashed in the early hours, two passengers are trapped with one in a critical condition, possibly paralysed, and another with a broken neck, but the driver is unharmed.

At the scene, the victims are being rushed to hospital and the driver is under arrest after failing a roadside drink-drive test, although he states he swerved to avoid a deer in the road.

Despite drink-driving being the likely cause of the collision, Crash Investigator Paddy Green needs to establish if there are any other factors, including speed and mechanical defects, or was the driver telling the truth? A closer inspection of the damaged car raises another issue, Paddy suspects none of the backseat passengers were wearing seatbelts, While Paddy awaits the results of drug and alcohol tests, he returns to the scene to check for signs of animals and runs speed tests using hi-tech equipment.

In York, Police Control receive a call from the Ambulance service to attend a serious incident involving a pedestrian who's tragically lost her leg after being run over by a suspected hit and run driver.

As police officers arrive on scene, the driver returns and is quickly detained for questioning, but the man claims the pedestrian ran out into the road from behind a parked car leaving him no chance to avoid her.

While the driver is detained in police custody under arrest after failing a roadside drugs test, witnesses come forward to describe hearing a loud engine noise leading up to the crash.

Crash Investigator Nigel Varney is called in to investigate whether the driver is to blame or if the Pedestrian was distracted in some way when stepping out.  A dangerous driving charge against the suspect could hinge on CCTV footage from near accident and Nigel calls in Paddy Green to help calculate the driver's speed at the time of the collision.
