EUGENE, Mo. - When junior Bailey Clark rolled her car on Tanner Bridge Road and when junior Hannah Burks totaled her favorite car on Route AA, they both had just dropped off their younger siblings after school.
Both teens had glanced at text messages just before their accidents.
"It was a blessing I was alone," Clark said. "It's scary to think about. What if (my 5-year-old brother) had been with me? He might not have made it."
That's why School Resource Officer Josh Stockman handed out hand-colored cards from elementary students to each Eugene High School student after the It Only Takes One safe-driving assembly.
"I want you guys making decisions to be safe, to wear your seat belt, to make right decisions," Stockman said. "If not for you, do it for those who are looking up to you. These kids are watching."
Unlike Clark and Burks, senior Dylan Evers's younger brother and a friend were in his truck when it was struck by a drunk driver in Brazito less than two years ago.
In his phone, Evers keeps pictures of his brother's slow recovery after multiple surgeries.
Always a safe driver, Evers' life was changed forever through no fault of his own. A driver made the wrong choice to get behind the wheel after drinking.
The It Only Takes One campaign hopes to prevent teenagers from making similar bad choices.
"I hope they don't have to go through what others have been through," Evers said. "We've learned the hard way."
The Missouri Highway Patrol's video and lessons from Sgt. Scott White were graphic. For those who have been in a car accident, they relived their own experience triggered by the mangled vehicles and bloody bodies on the screen.
But it was effective, as two students approached Stockman afterward, saying they had never thought about the elementary students who look up to them.
Clark and Burks hope their friends and peers will take heed to their life-altering accidents.
In April 2015, Burks was late to meet a friend, driving on a curvy road. She looked down at an incoming text. When she looked up, she was headed toward mailboxes, so she swerved and over-corrected before her vehicle rolled three times.
"It felt like I was going the speed of light," she said. "I remember the sound of crunching glass. It happened so fast, there was nothing you could do about it."
Burks pulled herself out through the driver's door, which was facing the sky. Her vehicle was a mess, but she escaped with only a scratch and a missing shoe.
"The first responders said I was lucky to be alive," she said.
Every day, Burks passes by the site of her wreck. It has changed the way she drives.
"It takes me forever to cross the highway," she said. "I don't speed anymore. I'm not glad I wrecked, but I was not a good driver before."
And Burks looks out for others. If the driver gets a text, Burks as a passenger will offer to take care of it for him.
Clark's accident right before prom in May also involved a glance at a text.
"I looked up, and I was straddling the road," she said.
Unfortunately, she hit the gas instead of the brakes, flipping her vehicle twice before she was thrown from the car.
"Seconds doesn't even describe how fast it happened," Clark said.
After school, Stockman returns to duty as a Cole County sheriff's deputy. That day, he was third on the scene, arriving to the call of an "ejection."
"It was the longest 15-minute drive," Stockman said. "You've got to be professional, but at the same time these are our kids."
Clark shattered her ankle, her ear was nearly torn off, suffered blood clots throughout her body and has scars across her face.
"I think it was my way of God saying, "This is your one free get-away,'" she said.
When Clark drives now, she doesn't even have her phone out.
She doesn't sugar-coat her story when someone asks. Most students think, "It won't happen to me."
"I think every person should know what it's like," Clark said. "People need to know that no matter how cool or popular you may be to drink, text or speed, you need to take a step back and look at the situation.
"You're not affecting just you."
