Williamson County, TX — January 1, 2026, one person was killed and Sonia Moore was injured in an alleged drunk driver accident at 11:45 p.m. on State Highway 45.

Additional details pertaining to this incident are not available at this point in time. The investigation is currently ongoing.

When I read about a wrong-way crash on New Year’s Day involving serious injuries and a fatality, I think about how often these incidents reflect not just one bad decision, but a series of missed chances to prevent harm. According to reports, the driver of the Porsche was traveling the wrong way and may have been drinking before the crash. Sonia Moore, who was driving safely in her lane, is now left seriously injured because of it.

In situations like this, one of the most important questions to ask is where the alcohol came from—and whether someone served that driver after he was already clearly intoxicated. Texas dram shop law allows alcohol providers—bars, restaurants, and others—to be held accountable if they overserve someone who then causes serious harm or death. The law doesn’t remove responsibility from the driver, but it does recognize that those who profit from alcohol have a duty to serve it responsibly.

Late-night and early-morning crashes on holidays like New Year’s are especially concerning because they often follow a predictable, preventable pattern. If a business continued serving this driver after it was clear he shouldn’t be drinking—let alone driving—then the harm suffered by Ms. Moore may have been both foreseeable and avoidable. That part of the story deserves as much attention as what happened on the highway.

Three key takeaways:

  • Under Texas dram shop law, alcohol providers can be held liable if they serve someone who is clearly intoxicated and that person later causes a serious or fatal crash.
  • Wrong-way crashes involving suspected drunk drivers—especially on holidays—often begin hours earlier at the location where alcohol was served.
  • Victims like Sonia Moore may have legal options beyond the driver, including the ability to investigate whether an alcohol provider contributed to the crash through negligent service.
