A mother has released footage of the moment her son was killed in a motorbike crash.
Brenda Holmes says she wants to make other bikers and motorists aware of the dangers on the road.
Last year, 38-year-old David died when his Yamaha motorbike crashed into a car on the A47 at Honingham near Norwich. He was doing more than 90 miles an hour.
Pictures of the crash were captured on David's helmet camera. Now Brenda's working with the police in Norfolk, broadcasting the footage on the police website as part of a road safety campaign.
The force admitted the move may prove controversial - but officers say its message may encourage drivers and motorcyclists to rethink their behaviour.
His mother Brenda Holmes, a retired nurse who lives in North Walsham, Norfolk, said she hoped that by telling the story, she could help prevent another family going through the heartache they continue to experience.
She said: "If we can prevent one accident; one family going through what we have been through then David would not have died in vain.
"I know he rode fast that day, he loved speed but he also loved life.
"This hasn't been an easy thing to do but I just hope that somebody benefits from the warning; that people slow down and take time to look for bikes.
"I'm not a perfect driver, I've done silly things sometimes and I've been lucky to get away with them, David wasn't lucky, the driver wasn't lucky."
After watching the footage, Mrs Holmes said one of the saddest things for her was that he could have predicted what was going to happen.
"He must have had a moment of fear at the end of his life; I find that very hard to deal with," she said.
"David was the most wonderful son and his loss has left such a void in our lives.
"Being without him has changed everything; our lives ended that day and I can truly say I know the meaning of heartache, it really does hurt; it's a physical pain."
Chief Inspector Chris Spinks, head of the Norfolk and Suffolk Roads Policing Unit, said the video was a brave move and he understood it would divide public opinion.
He said: "The video is shocking, however this is the reality of fatal collisions.
"The emotions people may experience after seeing this video can only touch the surface of those feelings that families and friends go through when losing a loved one in this way.
"The consequences of fatal collisions are devastating for all involved and as such our message though education has to reflect this.
"I firmly believe this footage is powerful enough to make riders and drivers think about their behaviour on the road; and most important of all, change it for the better."
