The answer is YES.  More often than not, the responsible party in a drunk driving accident is the intoxicated person who was driving the car that caused the accident. However, in some situations, a third party may be deemed liable for an accident caused by a drunk driver. Third party liability depends on many factors including the laws in the state where the accident took place and the jurisdiction of the court in which the case is being tried. A third party may be an individual (such as an employer, passenger, party host or law enforcement officer) or a business that provided alcohol (such as a bar or eating establishment). The situations may vary, but generally involve the third party having knowledge of the driver's intoxicated state and either failing to stop him or her from driving or providing him or her with more alcohol prior to driving. For instance, if a bartender continues to serve a visibly intoxicated individual with the knowledge that the individual will be driving (or fails to prevent the individual from driving) they can be held responsible for the accident. Also, if a police officer stops a car, sees that the driver is visibly intoxicated and allows him or her to continue driving the vehicle then the police officer could be held liable.
