Houston’s Drunk-Driving Crash Report
We pulled five years of Texas crash records for Harris County — 19,962 drunk-driving crashes — to show where, when, and how impaired driving actually hurts people here.
If you’re reading this after a drunk driver hurt someone you love, take a breath — the sorting-out part is our job now, not yours. We wanted to show, with real numbers instead of guesses, what drunk driving does in Harris County. So we pulled every reported alcohol-impaired-driving crash from 2020 through 2024. The picture is worse than most people think.
Across those five years, Harris County averaged nearly four people killed every week in crashes involving an impaired driver — 998 lives in all, plus another 1,358 people left with serious injuries and more than 10,000 injured overall. Houston proper accounts for about 63% of these crashes; roughly a quarter happen in unincorporated Harris County, with the rest in Pasadena, Baytown, La Porte and other nearby cities.
When drunk driving happens
The pattern here is unmistakable, and it matches what the science says about impairment. Drunk-driving crashes cluster hard on weekends and in the small hours of the morning.

Where drunk driving happens
Harris County’s freeways carry the most traffic, so it’s no surprise they carry the most impaired-driving crashes too. But the concentration on a handful of corridors and interchanges is stark. I-45 alone accounts for 112 of the 998 deaths.

The worst intersections and interchanges
Mapping the crashes down to specific intersections, the busiest freeway interchanges dominate. The I-69/US-59 and 610 Loop interchange is the single worst node in the county for drunk-driving crashes.

If a drunk driver hurt you or your family
Here’s the straight talk. A drunk-driving injury case is not an ordinary car-wreck case, and it shouldn’t be handled like one. The impairment changes what evidence matters, who can be held responsible, and what a fair recovery looks like. A few things worth knowing:
More than one party may owe you
The drunk driver is the obvious defendant. But under the Texas Dram Shop Act, a bar or restaurant that over-served an obviously intoxicated person can share responsibility. And your own uninsured/underinsured motorist (UM/UIM) coverage can be a backstop when the at-fault driver has little or no insurance.
The damages caps can fall away
Texas normally caps exemplary (punitive) damages. But that cap does not apply when the conduct qualifies as intoxication assault or intoxication manslaughter (Tex. Civ. Prac. & Rem. Code § 41.008; Penal Code §§ 49.07–49.08). In serious and fatal drunk-driving cases, that distinction can matter a great deal.
There’s a deadline — don’t sit on it
In Texas the deadline to file most injury and wrongful-death claims is generally two years (Tex. Civ. Prac. & Rem. Code § 16.003), but exceptions can shorten or extend it. Evidence — video, the vehicle, toxicology — also disappears fast. The sooner someone starts preserving it, the better.
Two different claims after a death
When a crash is fatal, Texas law recognizes a wrongful-death claim for the spouse, children, and parents (§ 71.002) and a separate survival claim belonging to the person’s estate (§ 71.021). They compensate different losses, and both can matter.

Methodology & sources
The figures in this report come from the Texas Department of Transportation’s Crash Records Information System (CRIS), the state’s official repository of Texas Peace Officer’s Crash Reports (CR-3). We queried all crashes in Harris County for crash years 2020–2024 flagged by TxDOT’s “Driving Under the Influence of Alcohol” filter — 19,962 crashes in total — and analyzed them for timing, location, and severity. Corridor and intersection rankings are based on the roadway and intersecting-street fields; freeway route codes have been translated to their common names. Location coordinates for the map are the median of geocoded crashes at each intersection.
TxDOT’s standard caveat applies: the Department makes no warranty as to the completeness or accuracy of the underlying data, and any conclusions drawn here are our own analysis, not those of the State of Texas or TxDOT. Data pulled July 2026. Citywide traffic-fatality context: City of Houston Vision Zero.
