A 58-year-old Stafford woman died in a crash involving a tractor trailer, Prince William County police said Wednesday.

Authorities said the woman, identified as Umme Habiba Begum, drove her vehicle across lanes near Jefferson Davis Highway and Wayside Drive in Dumfries.

On Monday afternoon, Begum was driving a 2012 Toyota RAV4 east from the Princeton Woods Shopping Center toward Wayside Drive when, for unknown reasons, she went over the median, according to a department press release.

The SUV went over the median and across the eastbound lanes, striking two pedestrian signals, the release said. Police said Begum’s vehicle then traveled north in the southbound lanes of Jefferson Davis Highway, where it collided with a 2001 Mack tractor trailer.

The tractor trailer overturned from the impact and the debris struck another vehicle on the highway, authorities said.

Begum was taken to an area hospital, where she died a short time later, police said. The tractor trailer driver, a 61-year-old Remington, Va., man, was not injured.

The release said speed, alcohol and drugs did not appear to be factors in the crash.
