An 18-year-old Texas cheerleader was killed after a driver smashed into her car while taking a breathalyzer test, reports said. Alexis Butler of Arlington was rushed to the hospital where she died Friday.

The unidentified 31-year-old driver took his eyes off the road for three or four seconds while blowing into a court-ordered ignition device. His pickup vehicle smashed Butler's Toyota Camry when she was backing the car out of a driveway. 

According to reports, the anti-DWI gadget shuts off a car when a driver is above the legal blood alcohol limit — but police tried to figure out why the driver was using it while the truck was moving.

“It’s very concerning to us, as a police department, that an individual may be operating some type of ignition device while they’re in a moving vehicle,” Lt. Chris Cook with the Arlington Police Department said, according to NBC News, adding it’s important, “to determine what the manufacturer recommendation is as far as the guidelines in how to operate this type of equipment.”

Police said the driver was not intoxicated at the time of the crash and had not been charged with the crime so far. The police department would forward the case to the district attorney’s office to determine whether the case should go to a grand jury. Local police said detectives are conducting a reconstruction of the crash scene as part of the investigation.

Butler’s family released the following statement to NBC 5, saying: “She was larger than life - everyone loved Lexxy — Her laugh, her smile, her bubbly personality. She touched so many people’s lives in just her short 18 years, more than most will touch in a lifetime. Her legacy will continue to live on through her final selfless act of organ and tissue donation, which she elected. She will continue to touch lives even in death. We know we’ll see Lexxy again in Heaven and she’ll be an angel watching over us.”
