A woman fell out of her car on a Texas highway while arguing with her husband — and was fatally struck by a passing car, according to authorities.

The unidentified woman was so upset with her husband as they drove home in Houston at 1 a.m. Saturday that she tried crawling out of their moving car at high speed, according to the Houston Chronicle.

She fell from the car on the city’s North Freeway — and a passing Chrysler Sedan ran into her. The woman was pronounced dead at the scene, the report said.

“It’s just an unfortunate tragedy,” Houston police Sgt. David Rose told the paper.

Police say she had been drinking, but her husband — as well as the driver of the car that hit her — were not intoxicated, according to Click2Houston. It was not immediately clear how she was trying to crawl out of the car or where she expected to go.

A second crash occurred when someone struck one of the people who tried to render aid during the accident. Another driver was detained at the scene for driving under the influence, the Chronicle said.
