Cinco de Mayo in San Antonio: The DWI Numbers Are Bad. The Part Nobody Talks About Is Worse.

Ok my friends, I love this city, I love Cinco de Mayo, and I love that San Antonio celebrates with everything it has, from downtown to the Southside to Stone Oak and every neighborhood in between. The food, the music, the energy. It is one of the best nights of the year in one of the best cities on earth.

But here is what I know from years of handling these cases: Cinco de Mayo is also one of the most dangerous nights to be on a San Antonio road. And the part that keeps me up is not just the drunk drivers. It is the bars and restaurants that helped put them there.

Let me show you the numbers first. Then I want to walk you through something some firms never even look at.

The Numbers: San Antonio and Bexar County

According to TxDOT’s 2024 Crash Records, the San Antonio area recorded 2,237 DUI-alcohol related traffic crashes in 2024. Those crashes resulted in 88 fatalities and 155 serious injuries.

That is more than six alcohol-involved crashes every single day in our community. Six crashes. Every day. For an entire year.

Zoom out to the state level. TxDOT reports that 1,053 people were killed in DUI-alcohol related crashes across Texas in 2024. One in four traffic deaths in this state involved a drunk driver. Three Texans lost every single day.

Why Cinco de Mayo Is Different

The National Highway Traffic Safety Administration (NHTSA) has consistently found that roughly one-third of all crashes on May 5th involve a drunk driver. In 2019, 38% of all traffic fatalities on Cinco de Mayo involved alcohol, compared to the typical 30% annual average. Forty-seven people died that single night.

Here in San Antonio, Cinco de Mayo falls in the middle of Fiesta season. SAPD data shows that during 2024 Fiesta, 139 DWI arrests were made. While that was a five-year low (down from over 270 in prior years), it still means well over a hundred people chose to drive drunk during the celebration. And those are just the ones who got caught.

For every DWI arrest, there may be dozens of impaired drivers who make it home without being stopped.

The Part Nobody Talks About: Who Served Them?

Here is what separates a good PI firm from a great one on these cases.

Some firms look at a DWI crash and see one defendant: the drunk driver. File the claim against their insurance. Settle. Move on.

We look deeper. Because in many of these cases, someone handed that driver drink after drink after drink while they were visibly, obviously intoxicated. A bartender. A server. A manager who told the staff to keep the tabs running on a busy Cinco de Mayo night.

That’s not ok.

Texas law recognizes this. It is called the Dram Shop Act, codified under Texas Alcoholic Beverage Code Section 2.02. When a bar, restaurant, or liquor store serves alcohol to a person who is already obviously intoxicated, and that person causes a crash, the establishment may be held civilly liable for the resulting damages.

Why does this matter? Because the drunk driver’s auto insurance policy may only carry $30,000 in coverage. For a family dealing with a wrongful death, catastrophic brain injury, or spinal cord damage, that number is insulting. A dram shop claim may open up significantly more coverage, because bars and restaurants typically carry commercial liability policies with much higher limits.

A Very Mini Masterclass: How a Dram Shop Case Actually Works

I want to pull back the curtain because I think people deserve to understand how these cases are built. This is not a simple "they served a drunk guy" argument. This is sophisticated litigation that requires expertise, science, and strategy.

Obvious Intoxication at the Time of Service

Under Section 2.02(b), a plaintiff must show that at the time the alcohol was provided, it was apparent to the provider that the person was "obviously intoxicated to the extent that he presented a clear danger to himself and others."

The law does not say "had been drinking." It says obviously intoxicated. Visible signs: slurred speech, stumbling, bloodshot eyes, belligerent behavior, inability to maintain balance, dropping things. The kind of thing where a reasonable person would look at that patron and think, "That person should not be served another drink."

This is where many cases live or die. And it is where the right experts become essential.

Toxicology and Retrograde Extrapolation

When a drunk driver causes a crash at 11:45 PM and blows a .22 BAC at the hospital at 12:30 AM, the question becomes: what was their BAC at 10:00 PM when the bartender handed them their seventh margarita?

A qualified forensic toxicologist can perform retrograde extrapolation, a scientifically accepted methodology where the expert works backward from a known BAC to estimate the person’s blood alcohol level at an earlier point in time. They account for absorption rates, elimination rates, body weight, food consumption, timeline of drinks, and other pharmacokinetic factors.

If the math shows the driver was likely at .18 or .20 while still being actively served, that may provide strong circumstantial support for the argument that their intoxication should have been apparent. A person at twice the legal limit is typically displaying observable signs of impairment.

Important caveat: Texas courts have held that a BAC number alone, without corroborating direct observational evidence, may not be sufficient to establish obvious intoxication. These cases require layered evidence. You may need witness testimony, surveillance footage, transaction records showing the volume and pace of service, and other circumstantial indicators working together.

The Safe Harbor Defense (and How to Overcome It)

Every bar in Texas has heard of the TABC Safe Harbor defense under Section 106.14 of the Alcoholic Beverage Code. The establishment can assert this affirmative defense if it shows: (1) it required employees to attend a TABC-approved training program, and (2) the employees actually attended. If those two elements are established, the burden shifts to the plaintiff to show the employer directly or indirectly encouraged the employee to over-serve.

The Texas Supreme Court clarified this in 20801, Inc. v. Parker.

So how do you overcome it? You can look for evidence of encouragement:

• Drink specials that incentivize volume ("$2 margaritas all night," "bottomless mimosas")

• Commission structures or tip pools that reward higher sales volume

• Management policies discouraging staff from cutting off patrons

• Understaffing on high-volume nights so servers cannot monitor patron behavior

• Failure to actually implement or enforce the training that was supposedly provided

• A history of prior over-service incidents at the same establishment

The Safe Harbor is not an automatic shield. It may protect responsible establishments that genuinely train and enforce. But many bars treat the TABC training as a checkbox exercise. They send the certificates to corporate, then go right back to pouring doubles for anyone with a credit card open. That gap between paper compliance and actual practice is where these cases may be won.

The Expert Team

A serious dram shop case may require a team of experts working in coordination:

Forensic Toxicologist: Performs the retrograde extrapolation. Establishes likely BAC at the time of service. Testifies about what physical signs of impairment a person at that BAC would typically display.

TABC/Hospitality Industry Expert: Testifies about industry standards for responsible alcohol service. What monitoring protocols a reasonable establishment should follow on a high-volume night. May also opine on whether the bar’s practices constituted indirect encouragement.

Accident Reconstructionist: Establishes crash mechanics, forces involved, and connects impairment to driving behavior. Helps establish proximate causation.

Surveillance/Video Analyst: Preserving and analyzing security footage from the bar can be some of the most powerful evidence. You may see the patron stumbling, being helped to their car, or displaying clear impairment while still being served. Time is critical. Many establishments overwrite footage within 30 to 90 days.

Why This Matters Tonight

If you are heading out tonight (and you should, go enjoy it), please have a plan to get home safe. Rideshare, designated driver, a friend with a couch.

But if the worst happens. If someone who was over-served at a bar crosses the center line and changes your life or the life of someone you love, I want you to know that the drunk driver may not be the only one who bears responsibility.

The establishment that kept pouring may be accountable too. Texas law exists to hold them to that standard. And a firm that knows how to investigate the dram shop angle, how to preserve the evidence before it disappears, how to retain the right experts, how to overcome the Safe Harbor defense, that firm may be the difference between a $30,000 policy-limits settlement and full, fair compensation for what was taken from you.

We look beyond the driver. We always have.

Be safe tonight, my friends. Make the memories. And know that if something goes wrong out there, reach out, we’re here.
