It can be hard for people to imagine the devastating ripple effect of a serious crash, such as yesterday's horrific double fatality in Jandakot.
But that is what Paula Miller tries to communicate to teenagers week-in, week-out as one of three RAC community education officers.
"We have a presentation called 'My Decisions, My Destination', which is real case studies of fatal crashes," Ms Miller said.
"We do an activity on the ripple effect and who was affected by that crash and who would be affected if it happened to them?
"Parents and grandparents, friends, ambulance drivers, police, witnesses, sports coaches, workmates - it's quite powerful.
"We always advise students before showing real life stories that they can leave the classroom."
Ms Miller and the education team delivered the Resilient Drivers program to 35,000 year 10-12 students across WA last year. She said the RAC's approach to safety education - more stark reality than shock value - was the best way to get through to teens.
"We take that approach because a lot of young people, especially aged 16-24, think they're bulletproof and it's not going to happen to them," she said.
"Seeing something that is hard-hitting might just make them think twice before they make a choice to text or speed or drink-drive. If the kids are laughing and playing up and think it's a bit of a joke, you do put the hard word on them - 'I'm here to save your life. Have a look at the person next to you, what would you do if they were in your car and you made a mistake?' "
A mother of teenagers aged 17 and 19, Ms Miller said she now had a passion for spreading the road safety message.
"I've been lucky that I've had no one close to me involved in crashes," she said."But I have teenagers and what I've learnt in the past two years is helping me encourage them to drive safely. If I could just save one life, I'm doing my job."
