This area of the law is addressed in Texas Dram Shop Laws. It stipulates any business's legal responsibility-- to stop serving any patron who is intoxicated enough to present a danger to themselves or others. The establishment owes the public a duty of care to not allow someone to operate a vehicle when they are unfit to do so. It is crucial to note that overserving a patron who causes an accident does not in itself necessarily mean that the establishment is liable. In addition to having overserved the patron, your Dallas car accident lawyer must prove that the driver's intoxication proximately caused the accident itself.
