Hairdresser Brooke Richardson had been driving to work in 2012, when she sent a text message to a client asking: "Are you still going to make it today?"

The 20-year-old P-plate driver never made it to work, after she was killed when her car hit a tree in the Victorian town of Cobram, near the New South Wales border.

Brooke had sent her final text message while travelling at 100 kilometres per hour.

Brooke's mother Vicki Richardson hopes sharing the "ordinary" last text messages people send before being killed or injured behind the wheel will make others want to stop texting while driving forever.

"People don't look at the raw truth," she said.

"I suppose they look at the need of the moment, that instant gratification.

"Don't make your parents have to do what I've done."

Ms Richardson started the foundation Don't text-n-Drive after her daughter's death, and wants something real like her own devastating loss to hit home to young people.

She is also supporting the NSW Government's renewed campaign to highlight the dangers of texting while driving, by using those last messages people send to show just how much trivial texts like "chicken for dinner?" can cost them.

"It is extremely frustrating young people are still texting while driving even in our own small town after Brooke's death," Ms Richardson said.

She said that one year before her death, a friend of Brooke had revealed she had been texting while driving and that it was dangerous.

"I spoke with her and asked her to stop," Ms Richardson said. "I think she stopped for a little bit, but then the temptation just kicks [in] and that is greater than the realisation of what can actually happen."

Phone distraction big among youth

The NSW Government and the NSW Road Safety Centre said mobile phone distraction was a real problem, with nearly 39,000 people charged last year for using their mobile phone while driving.

NSW Roads Minister Melinda Pavey said young people were among the worst offenders.

"People aged between 25 and 34 are the worst mobile phone offenders, with 13,790 people in that age group charged last year with breaching the state's mobile phone laws," Ms Pavey said.

"People aged 65 and over had the lowest offending rates, while those aged 18-20 had the second lowest offending with just 1,097 people charged last year."

Ms Pavey said the latest initiative was a continuation of the Get Your Hand Off It campaign launched in 2013.

Ms Richardson said she wanted to prevent other parents going through the devastation she has.

"I honestly think the more education we put out there the better, we need to immerse young drivers in the message, like the successful Don't Drink and Drive and anti-speeding campaigns."
