Is it worth your time to pursue an additional claim against a business or person who served the alcohol to the driver?
It can be.
If your case is successful, the court will award damages to cover your medical bills, lost wages, compensation for lost or damaged property, and pain and suffering. If a driver is driving while intoxicated, and the intoxication is a proximate or immediate cause of the losses, the driver can also be responsible for punitive or exemplary damages, as well. These damages are intended to punish and are in addition to the usual damages. The driver's liability insurance is usually required to pay these damages to the extent of the policy.
No punitive damages can be assessed against an establishment (Dram Shop) under current Texas law, but other appropriate damages can be awarded.
When our Arlington firm takes a dram shop case, Rocky Walton ordinarily does not want to settle the claim against the drunk driver before he settles against the bar or restaurant. In that way, the jury is angry with the driver and will pour on the damages. However, the liability will be apportioned between the drunk driver and the bar. The jury will normally assign most of the negligence to the drunk driver. This is not good in the usual case of when the insurance coverage of the bar is greater than the coverage the drunk driver has.
The specific amount you receive will depend heavily on the details of the case. Ideally, it will be enough to pay off any financial losses that resulted from the accident so that you can focus on recovering, rather than paying the bills.
