She was driving alone on the northbound side of Route 128 Saturday afternoon when a truck, traveling on the opposite side, lost two of its tires, according to Waltham fire Lieutenant Stephen Centofanti. One of them bounced into her car.

State Police on Sunday identified the victim as Rose DeDominicis of Boston.

A 27-year-old woman suffered serious injuries after a tire flew off a truck, bounced across the median, and crashed into her car Saturday in Waltham, officials said.

Centofanti said the woman had lacerations to her face and broken teeth, but was “lucky to be alive.”

“If the tire was six inches to the right she would be dead,” he said.


The truck driver, Valvir Dossantos, 48, of Lowell, was charged with operating without a license, State Police said.



Dossantos was unharmed as his truck slid down the road 200 yards, according to State Police Sergeant Jeffrey Joanchin. Two fire engines were sent to the scene.

DeDominicis was extricated from her car and taken to Lahey Hospital and Medical Center in Burlington. She was released from the hospital later in the day.

“The engine of the car basically came out,” he said.
