Crashes at I-10 & Grand Parkway.

Why this intersection is dangerous

The widest freeway in North America meets the outer Grand Parkway beltway at one of the fastest-growing interchanges in Texas. Rapid suburban expansion in Katy has outpaced infrastructure updates. Merging, exiting, and lane-changing happen in compressed distances at highway speeds.

Crash patterns our attorneys see at this intersection

High-speed rear-end chain reactions during congestion, sideswipe collisions during lane changes, and serious 18-wheeler crashes — this segment carries heavy commercial truck traffic. Rollover and jackknife incidents occur on the ramps.

Common injury types

Catastrophic injuries consistent with highway-speed impacts: traumatic brain injury, spinal cord injury, internal injuries requiring surgery, and higher fatality rates than surface-street intersections.

Evidence that needs to be preserved — fast

TxDOT traffic cameras cover portions of this interchange. Commercial vehicles involved in crashes here typically have electronic control module (ECM) data, driver hours-of-service logs, and dashcam footage that must be preserved through formal preservation letters within days.

Every injury case is stronger when evidence is locked down early. We send preservation letters to every business within line-of-sight of the crash, request dashcam footage from rideshare platforms, subpoena traffic engineering records where relevant, and obtain the Texas Peace Officer's Crash Report (CR-3) as soon as it becomes available through TxDOT's Crash Records Information System.

What to do right now if you were injured here

• Get medical care even if you feel okay — adrenaline masks injuries, and gaps in treatment are the #1 argument insurance companies use to reduce claims.
• Do not give a recorded statement to the other driver's insurance company without an attorney. You are not legally required to.
• Do not sign a release or accept a quick settlement offer in the first days or weeks. Early offers are almost always far below case value, and signed releases are permanent.
• Document everything: photos of the vehicles, the intersection, debris, skid marks, traffic signals, weather, and any visible injuries.
• Call an attorney before insurance pressure builds. Consultations are free — a bad early statement costs tens of thousands in recovery.

Texas law that will shape your case

Two-year statute of limitations

Under Texas Civil Practice & Remedies Code §16.003, most personal-injury lawsuits must be filed within two years of the date of injury. Claims against government entities — for example, if a signal malfunction is part of the case — can require notice in as little as 90 days under the City of Houston charter.

Modified comparative fault — the 51% bar

Texas follows a modified comparative negligence rule: if you are 50% or less at fault, you recover damages reduced by your fault percentage. At 51% or more, you recover nothing. Insurance adjusters push fault onto victims aggressively to trigger the 51% cliff. How the 51% bar works →

Stacking coverage beyond the at-fault driver's policy

At high-volume intersections like I-10 & Grand Parkway, catastrophic injuries frequently exceed the at-fault driver's minimum Texas liability limits (30/60/25). Our firm maps every potentially available policy — the at-fault driver's personal policy, any employer coverage if the driver was on the job, commercial umbrellas, your own UM/UIM coverage, and in drunk-driver cases, potential dram shop liability against bars that over-served.
