Yes. Under Texas law, a driver who causes a crash while intoxicated is liable for the injuries and damages the crash causes, and evidence of intoxication — a DWI/DUI conviction, blood alcohol results, or police reports — can support a personal injury claim in civil court, separate from any criminal charges the driver faces.
In addition to suing the driver, injured victims may also have a claim against a bar, restaurant, or business that continued serving a visibly intoxicated patron under the Texas Dram Shop Act (Tex. Alco. Bev. Code Ch. 2). An experienced Houston personal injury attorney can help identify every potentially liable party after a drunk driving crash.
