If you were hurt in a car accident in Katy, the first thing to know is that “Katy” is not one jurisdiction: the Katy area takes in parts of Fort Bend, Harris and Waller counties, and which county the crash happened in decides the police agency that wrote the report and the courts that would hear a lawsuit. The firm’s only office is in southwest Houston, not in Katy.
The short version
- Three counties. The Katy Area Economic Development Council says the area covers portions of Fort Bend, Harris and Waller counties, with the entire City of Katy inside it.
- The city’s own numbers are modest. TxDOT recorded 1,092 crashes in the City of Katy in 2024: none fatal, 10 with a suspected serious injury, 12 people seriously hurt.
- Two big roads. I-10, the Katy Freeway, and State Highway 99, the Grand Parkway, where TxDOT has planned a widening.
- Venue follows the crash. A Texas injury suit is generally filed in the county where the events happened (Civil Practice and Remedies Code § 15.002(a)(1)).
- One office, honestly described. We have no Katy office; we serve Katy clients from 8313 Southwest Freeway in Houston.
What county is Katy, Texas in, and why does it matter after a crash?
The Katy area sits in three counties: Fort Bend, Harris and Waller. The county where your crash happened decides which sheriff’s office or constable may have responded, which county’s courts could hear a lawsuit, and which clerk holds the filings. A Katy mailing address does not settle any of that.
The Katy Area EDC describes the area’s footprint as “portions of three counties: Fort Bend, Harris, and Waller,” containing the entire City of Katy, parts of the City of Fulshear and some unincorporated areas of the City of Houston (Katy Area EDC, Government, read 16 October 2026). The same page says the area’s school districts are Katy ISD and Cypress-Fairbanks ISD. So a driver with a Katy address can be hurt on a city street, in an unincorporated Harris County subdivision or in Fort Bend County, and each of those has a different answer.
Texas law ties the courthouse to the crash. Section 15.002(a)(1) of the Civil Practice and Remedies Code places a lawsuit in the county where all or a substantial part of the events or omissions behind the claim occurred; the next paragraphs of that subsection cover the defendant’s residence or principal office (chapter 15, text read 16 October 2026). For a general picture of how a claim runs once the venue is clear, see our Katy personal injury page and our Houston car accident lawyers page.
How many car crashes happen in Katy, Texas?
TxDOT recorded 1,092 crashes in the City of Katy in 2024. None was fatal, 10 caused a suspected serious injury and 12 people were seriously hurt. These are TxDOT’s figures for the City of Katy; they are not figures for the wider three-county Katy area.
| Measure | City of Katy, 2024 |
|---|---|
| All recorded crashes | 1,092 |
| Fatal crashes | 0 |
| People killed | 0 |
| Suspected serious-injury crashes | 10 |
| People seriously injured | 12 |
Source: TxDOT, Crashes and Injuries, Cities and Towns, 2024, read 16 October 2026. TxDOT says the counts rest on officers’ crash reports it had processed by April 9, 2025.
A small number is not a reason to skip a claim. A crash with no deaths can still put someone in a hospital for weeks, and the table says nothing about the roads outside the city limits. The Katy figure also says nothing about fault, which is decided case by case; our Houston roads and intersections article looks at the city next door with its own data.
What is happening on the Katy Freeway and the Grand Parkway?
State Highway 99 is slated for a widening. TxDOT planned to expand SH 99 between I-10 and US 290 from two lanes each way to three, after finding evening speeds fall from about 65 mph to about 30 mph on that segment, according to ABC13’s August 2025 report.
ABC13 reported on August 22, 2025 that TxDOT expected to break ground in mid-2026 on the SH 99 expansion between the Katy Freeway and US 290, a $157 million project paid from toll revenue funds, with construction to finish by the end of 2030 (ABC13, read 16 October 2026). A TxDOT spokesperson told the station the widening traces to a 2009 agreement with the seven counties of the Grand Parkway Corporation. That is a 2025 plan; we have not confirmed this month whether work has started, so check TxDOT or Houston TranStar before you drive the corridor.
Construction zones and merging traffic change how crashes happen. A rear-end collision in a slowdown is different from a lane-change crash at an interchange, and our pages on distracted driving accidents and liability in multi-car accidents explain how fault is sorted out in each.
What about 18-wheeler crashes on I-10 near Katy?
Truck crashes can involve several insurers and defendants. FOX 26 reported on July 1, 2026 that an 18-wheeler crash on I-10 at State Highway 6 killed two people and closed the eastbound Katy Freeway completely. Truck cases can reach more than one defendant.
FOX 26 Houston published the report on July 1, 2026, saying Houston Transtar reported a complete closure of I-10 Katy eastbound at Highway 6 after a crash involving an 18-wheeler, and that the driver of the 18-wheeler and the driver of the other vehicle were both dead (FOX 26 Houston, read 16 October 2026). The story was labeled breaking news and does not say where the crash falls inside Katy’s city limits, so we cite it only for what it says: an 18-wheeler crash on this freeway killed two people.
Truck cases bring the motor carrier, the driver and sometimes a maintenance or cargo company into the picture. Our Katy 18-wheeler and truck accident page and the general Houston trucking accident page cover that claim, and the articles on who can be held liable and an October 2026 overturn on the West Loop at I-10 show how those cases develop.
Which police agency writes the report for a Katy crash?
It depends on the location. The City of Katy has its own police department, but the area is also patrolled by Fort Bend County Sheriff’s deputies, Harris County law enforcement in unincorporated areas, deputy constables and Katy ISD’s police force. Look at the crash report to see which agency responded.
The Katy Area EDC lists the city’s police and fire departments, Katy ISD’s own police force, “over a thousand sworn officers” in unincorporated Harris County, Fort Bend County Sheriff’s units patrolling subdivisions and deputy constables who patrol the Katy area; outside municipalities, fire protection comes from emergency service districts such as Harris County ESD #48 and Fort Bend ESD #1 (Katy Area EDC, read 16 October 2026). More than one agency can touch a single crash, and the report names the one that investigated.
The report matters because it is the first thing insurers ask for. TxDOT’s online system holds reports from Texas law enforcement agencies, and the steps to buy one, who may request it and what it costs are in our guide to ordering a Texas crash report. If you were hurt, photograph the scene first; which photos to take is a short read.
Which courts hear a Katy car accident case?
Whichever county the crash happened in: Fort Bend County’s district courts and county courts at law, Harris County’s civil courts in Houston, or Waller County’s courts. Harris County civil courts at law can hear civil claims up to $250,000, so the amount in dispute also affects the court.
Fort Bend County’s district courts page names ten district courts, from the 240th to the 505th, (Fort Bend County, District Courts, as read on 16 October 2026), and its county courts at law list runs from Court at Law 1 to Court at Law 6 (Fort Bend County, County Courts at Law, as read 16 October 2026). On the Harris County side, the Civil Courts at Law site says a county civil court at law can take civil matters worth up to $250,000 (Harris County Civil Courts at Law, Venue and Jurisdiction, read 16 October 2026). We did not find a Waller County court source we could open, so we say nothing more about those courts here.
For the court stage, read our overview of how long a Texas injury case takes. Neighbors in Sugar Land and Richmond, which lie in Fort Bend County, face the same venue question, as do the readers of our article on Missouri City and Richmond accident cases.
What deadlines and fault rules apply to a Katy car accident claim?
Texas rules are statewide: usually two years to sue for personal injury, and no damages for a claimant found more than half responsible for the crash. Confirm your own deadline with an attorney, because the statute lists exceptions.
The limitations statute, § 16.003(a), sets two years from accrual for a personal injury suit, subject to exceptions in three other sections (chapter 16 of the Civil Practice and Remedies Code, text read 16 October 2026). Under § 33.001, a claimant whose share of responsibility is above 50 percent recovers no damages (chapter 33, text read 16 October 2026). Our article on how lawyers answer comparative negligence arguments explains how that plays out.
In the weeks after a crash, other things move faster than a court date: the adjuster’s call, your medical bills and a hit-and-run or uninsured driver. Before giving a recorded statement, see our advice on dealing with the adjuster. If the other driver left or has no insurance, see our guides to hit-and-run claims and uninsured and underinsured motorist coverage, and our checklist of steps after a car accident.
