“People say it was an accident and that accidents happen but it didn’t feel like an accident, I knew I never meant to do what I did but I was completely responsible for what I did (speeding)

“ …Having to deal with the guilt which comes through taking a life. It’s almost unbearable.”

These are the repentant words from David, a young driver, who pleaded guilty to death by dangerous driving, excessive speed was a main cause of the collision.

Thames Valley Police and Hampshire Constabulary are encouraging people to watch, listen and share David’s experience and remind motorists there is no such thing as safe speeding.

Sgt Rob Heard, from the Joint Operations Roads Policing Unit, said: “We want people to be able to understand and relate to the fact this is the real consequences, it could very easily happen to you or your loved ones.

“If you speed you are risking not just yours but other innocent people’s precious lives. It’s simply not worth the risk.

It is all part of an ongoing campaign at highlighting to motorists the risks involved in speeding during the week of action against speed.

David wants motorists to come away and think about what if it all goes wrong. He says: “I’d think nothing of driving up to 100mph on the motorway or national speed limit looking for some thrills and having a laugh on the road. You got to think about what if it goes wrong, because you know I wouldn’t have ended up killing somebody and going to prison all for the sake of overtaking a car.”

He’s asking others to: “Look at what’s happened to me think about what’s happened to me and you know how easily it could happen to you.

"The smallest, silliest little decision can have such massive life changes, when you least expect it as well. It will change your life forever and other people’s.”

David was sentenced to three years in prison and disqualified him from driving for six years after a pensioner died following a head-on crash which happened when he tried to overtake six cars on a dark road.

Sgt Rob Heard said: “This has been a very sad case for all involved. We are grateful that the victim’s family and David were happy to have this case shared to highlight how dangerous speeding can be.”
