If a person is drinking at a bar, and the bar staff lets that person drive away in a car, is the bar responsible if the driver gets into an accident on the way home?

Yes, a court may find them liable. South Carolina law recognizes the liability of establishments who over-serve their patrons, and the law requires that these establishments purchase at least $1 million in liquor liability insurance if they serve alcohol to their customers after 5 p.m.
