Police tried to pull the woman over on Clubhouse Drive in Leesburg, but she hit the gas pedal and sped away, the Loudoun County Sheriff's Office said. She crashed into three cars and a Sheriff's deputy's cruiser before her car died, officials said.
Deputies took her to a local hospital for observation.
Authorities have not released her name, and charges are pending until doctors release her, Sheriff's Office spokesman Kraig Troxell said.
