EPISODE three of BBC show The Crash Detectives followed Gwent Police as they investigated two serious crashes on the M4 and in Newport.

The first crash featured was a fatal crash when mum-of-two Georgina Coombs, 38, crashed her Vauxhall Astra into a BMW while driving the wrong way up the M4 on February 22, 2019.

Ms Coombs was killed in the crash and the driver of the BMW, Dale Jones, suffered life-changing injuries.

Before the crash, Gwent Police were flooded with calls informing them of the Astra driving the wrong way up the M4, but they were not able to stop the crash.

Forensic collision investigator Dean Burnett noted that it looked like a head on crash, but the rear driver's side wheel on the Astra was out of alignment which was not consistent with a head on collision.

However, he found that the Astra had hit the crash barrier during the crash and realised that if it was not that specific type of barrier, then the Astra could have landed on the other carriageway.

The next day, investigators found that the Astra had not been for an MOT in almost three months and did not have any insurance on it, though it was in good condition before the crash.

Investigators then tried to find out why Ms Coombs drove the wrong way down the M4 and were convinced it was a deliberate act.

However they were sure that she did not intend to crash, as footage showed she tried to brake before the impact.

It was then found that Ms Coombs had been to a family party and her blood levels showed she had two and a half times the legal limit of alcohol and had also taken cocaine.

Investigators were convinced that Mr Jones did not contribute to the crash with any dangerous driving of his own.

Stow Hill

In the other crash featured, a 23-year-old motorcyclist was left with serious injuries after crashing into a van in Stow Hill, Newport on March 22, 2019.

The motorcycle crashed into the van as the van attempted to make a right turn.

The motorcyclist's injuries were so severe because he did not fasten his helmet, so on impact it flew from his head instead of absorbing the impact.

Poliice recognised the motorcyclist as a man they had previously stopped for drug driving, but none of the available evidence showed that the crash was his fault.

However, officers found bags of cannabis and a large quantity of cash in his possessions, indicating that he was a drug dealer.

Officers noticed nearby CCTV cameras and realised from the footage that the van had cut the corner while turning.

Therefore, the crash was not the motorcyclist's fault, as he had right of way.

The motorcyclist recovered from his injuries and pleaded guilty to possession of cannabis with intent to supply.

The van driver was given formal advice from the Police about the standard of his driving.
