Four Lawrenceville teenagers were injured Monday night when a car drove off Webb Gin House Road and struck a tree, Gwinnett police said.

About 10:30 p.m., Ashlyn N. Boyd was eastbound at a high rate of speed when the 1996 Honda Civic she was driving veered off the roadway, according to an incident report obtained Tuesday by The Atlanta Journal-Constitution. She overcorrected, lost control of the car and struck a tree on the other side of the road, police said.

Boyd, was not wearing a seat belt, was ejected, according to the report. All four teens in the vehicle were taken to Gwinnett Medical Center-Lawrenceville. Two of the passengers were 16 years old. The third passenger was 15 years old. Boyd, whose age wasn’t specified in the report, was born in 1998, police said.
