An 18-year-old died on Friday after another driver smashed into her car because he'd taken his eyes off the road for a moment to adjust a device in his truck used to prevent drunk driving.

Alexis Butler, from Arlington, Texas, died a week after the crash from the severe injuries she'd sustained.

She was hit on her passenger side by a pickup truck as she backed her Toyota Camry out of her driveway.

She was hit on her passenger side by a pickup truck as she backed her Toyota Camry out of her driveway when a driver looked away from the road for a moment to turn off a device in his car that prevents drunk driving

Police told NBC 5 that the driver of the pickup truck, who hasn't been identified, admitted to looking down for a few moments to turn off a device in his car that prevents drunk driving.

He said he had to breathe into a court-ordered ignition interlock device, which turns off a car when the driver is over the legal blood alcohol limit.

Cops said there were no skid marks on the road after the crash, showing that the 31-year-old didn't see her car and slow down before the collision.

'Number one thing we'll look at is tracking down the original court order to read exactly what it said,' Lt Chris Cook told the network.

'And more importantly for us as a police department, is to determine what the manufacturer recommendation is as far as the guidelines in how to operate this type of equipment.

'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.'

The driver wasn't impaired at the time of the crash, and hasn't been charged with anything yet. Police said though that other charges are possible once they can gather more information.

Butler's family told NBC that their daughter was 'larger than life,' and that she was selfless even in death, electing to donate her organs

If charges are filed the district attorney would decide if the case should go to a grand jury.

Butler's family told NBC that their daughter was 'larger than life.'

'Everyone loved Lexxy,' they said in a statement to the network.

'She touched so many lives in just her short 18 years, more than most will touch in a lifetime.'

They also said that she exemplified her selflessness in her death through organ and tissue donation.

'We know we'll see Lexxy again in Heaven and she'll be an angel watching over us,' her parents said.
