The Tennessee Supreme Court has ruled a Chattanooga woman hit by a drunk driver in a Walmart parking lot can proceed with her suit against the store.

In February of 2011, Jan Mccool was kicked out of the Signal Mountain Walmart on the suspicion she was drunk.

She got in her car and backed into Jolyn Cullum as she loaded groceries into her vehicle.

"Pinned her between the two cars, kept backing up. People had to run in, screaming, telling her to stop," says Amelia Roberts, Cullum's attorney.

Cullum is suing Mccool and Walmart for $1 million saying store employees were negligent and could have prevented the accident.

"They threw her out of the store knowing she was alone, knowing she was intoxicated, knowing she was belligerent," says Roberts.
