Violet was at home watching the X Factor when the phone rang. It was the mother of one of Steven's friends, saying Steven had fallen off his bike. Her husband set off in the car to pick him up, but when he got to the place where Steven was, the police stopped him from going any closer.

Steven was taken to hospital and when Violet got there, she was told that he'd been hit by a speeding driver and the medical team were working on him. About half an hour later, Violet and her family were told that Steven's injuries were so severe that the doctors were unable to save his life.

Violet says that at that moment, her heart just snapped.

For the first few weeks, it was hard to believe what had happened. 'It was as if he was just away on a school trip,' says Violet.

They later found out that the driver who had hit Steven was driving faster than 50mph on a road with a speed limit of 30mph. Steven and his friends were crossing the road but the driver didn't slow down and when he hit Steven, he was knocked from one side of the road to the other. The driver was convicted of causing death by careless driving and received a prison sentence of 16 months.

Steven was born with a cleft palate and was disagnosed with leukaemia when he was two years old. He spent a lot of time in hospital and even fundraised for charities while he was on the ward. Violet says he was cheeky and everyone loved him. After Steven died, Violet found a Christmas list he'd written, asking Santa for 'Five Playstation games, some new football boots and £500 please!'

Steven, 12, was hit by a speeding driver while crossing the road. He was taken to hospital but his injuries were too severe for doctors to save him.

The hardest thing is he'll never have a life, he'll never grow up, you don't know what he would have become. It's just like your life's gone. It's like a light has gone out. I've still got lights, but one of them is missing. That light will never brighten again, and you cannot replace it.

Violet got in touch with Brake who helped her explain Steven's death to her daughter. Brake sent her a picture book that helped her to talk about Steven's death.

Violet is sharing her story in the hope that just one person will listen and really try and look at their speed and figure out how not to speed. Or one person will look where they are going and do everything they can possible. 'If it saves just one life,' she says, 'it means someone is listening, and at the end of the day that's all we want.'

Hear Violet talk about how Steven's death affected her family, and how Brake helped her talk to her daughter about what had happened.
