(CNN) - Car accidents are the number-one cause of death for teenagers. And 25 percent of all teen driving crashes are due to distracted driving.
Since April is National Distracted Driving Awareness Month, events are being held all over the country to try and focus teens behind the wheel.
Bonny Spray knows first-hand, the dangers of distracted driving:
[2:06] “Six years ago on this date, my daughter was pronounced dead following a single-car accident from texting and driving.”
Spray and her 19-year-old daughter Amanda were trading text messages about a fight Amanda was having with her roommate.
[2:43] “The last text I got was, ‘I‘m not doing too well.’”
Spray now goes to high schools to share her daughter's story and talk about the dangers of distracted driving.
Outside John Burroughs High School in Burbank, California, teen volunteers get set to take the distracted driving challenge; an obstacle course that’s more about the distractions inside the car than those outside it.
