Quick Answer
After an I-35 and I-10 interchange wreck in San Antonio, move to safety if possible, call 911 when anyone may be injured or a vehicle cannot be safely driven, and record the exact direction, level, ramp, and nearby exit. Fault is not automatic in a merge crash. Texas law asks whether each driver changed lanes safely, signaled, followed at a safe distance, drove at a reasonable speed for traffic and construction, and maintained a proper lookout. Ryan Orsatti Law helps injured people evaluate fault, insurance coverage, and evidence preservation after serious highway crashes.
Key Takeaways
- Identify the exact crash location, including northbound or southbound, upper or lower level, connector ramp, travel lane, and nearest exit.
- A merging driver is not automatically 100% at fault. More than one driver can share responsibility under Texas law.
- Do not assume TxDOT recorded the wreck. TxDOT states that its live traffic-camera footage is not recorded.
- Preserve dashcam files, vehicle data, photographs, witness information, and commercial-vehicle records before they disappear.
- Texas generally allows two years to file a personal injury lawsuit, but evidence and some notice deadlines can become urgent much sooner.
Why are I-35 and I-10 interchange wrecks different from ordinary crashes?
I-35 and I-10 interchange wrecks can be harder to investigate because the downtown corridor includes upper-level lanes, the Finesilver Curve, connector movements, traffic shifts, and changing lane configurations. TxDOT currently describes a $25.9 million repair project covering 5.5 miles of I-35 and I-10, with phased work estimated through 2026 and temporary lane shifts and closures during construction.
Construction does not automatically make TxDOT or a contractor responsible for a wreck. It does mean that photographs of lane markings, barrels, barriers, warning signs, pavement conditions, and the exact lane split may become unusually important.
The broader safety numbers show why careful driving and prompt evidence collection matter. TxDOT reported 39,805 crashes within San Antonio in 2024, including 170 fatalities. Those figures are citywide, not limited to I-35 or I-10. TxDOT also reported more than 28,000 Texas work-zone crashes and 203 deaths in 2025.
Who is at fault after an I-35 or I-10 merge crash in Texas?
Fault depends on what every involved driver did before impact, not simply on who was merging. A driver entering another lane must make the movement safely, but a driver already in the lane may share responsibility for excessive speed, unsafe following distance, distraction, or failing to react reasonably to visible traffic conditions.
Texas uses proportionate responsibility, which means fault can be divided among multiple people or entities. Under Texas Civil Practice and Remedies Code § 33.001, an injured claimant cannot recover damages if the claimant is more than 50% responsible. If the claimant is 50% or less responsible, any recovery is generally reduced by that percentage.
Which Texas traffic rules usually matter in an interchange crash?
The most important Texas traffic rules usually concern safe lane movement, signaling, following distance, speed for existing conditions, and ordinary care. These duties operate together, so an unsafe merge can coexist with negligent conduct by a second driver who was speeding, tailgating, distracted, or unable to stop safely in congested traffic.
| Liability issue | Texas rule | Evidence that may help |
|---|---|---|
| Unsafe lane change | Texas Transportation Code § 545.060 requires a lane movement to be made safely. | Lane markings, scrape patterns, impact angles, dashcam video, witnesses |
| Failure to signal | Texas Transportation Code § 545.104 requires signaling an intended turn or lane change. | Video, witness statements, vehicle-camera footage |
| Following too closely | Texas Transportation Code § 545.062 requires an assured clear distance based on speed, traffic, and road conditions. | Rear-impact damage, event data, braking evidence, traffic video |
| Unsafe speed for conditions | Texas Transportation Code § 545.351 requires a reasonable and prudent speed under existing circumstances. | Event data recorder information, debris, roadway conditions, witnesses |
| Inattention or poor lookout | Texas negligence law requires drivers to use ordinary care under the circumstances. | Phone records when properly obtained, video, admissions, witness observations |
Key takeaway: The lane-changing vehicle may carry substantial fault, but the physical evidence can show that another driver’s speed, following distance, or inattention also contributed.
What should I do immediately after an I-35 and I-10 interchange wreck?
First protect people from a second collision, then document the crash without exposing yourself to moving traffic. Texas law requires drivers involved in injury crashes to stop, exchange identifying and insurance information, render reasonable assistance, and promptly report crashes involving apparent injury, death, or a vehicle that cannot be normally and safely driven.
- Move only when it is safe. If the vehicle can be driven and moving it will reduce danger, pull to a safer location. Do not stand in an elevated travel lane or between damaged vehicles.
- Call 911 when required or medically appropriate. Report any possible injury, hazardous debris, disabled vehicle, fire, fuel leak, or dangerous lane obstruction.
- Describe the location precisely. State the interstate, direction, upper or lower level, ramp or connector, nearest exit number, overhead sign, and whether the crash occurred before or after the lane split.
- Photograph the scene from safety. Capture vehicle positions, all sides of each vehicle, damage, debris, skid marks, lane lines, construction devices, barriers, signs, and visible road defects.
- Identify every involved vehicle and driver. Obtain names, phone numbers, license plates, insurance information, employer names, company markings, and USDOT numbers on commercial vehicles.
- Ask witnesses for contact information. A neutral witness may be critical when two drivers give conflicting merge accounts.
- Seek appropriate medical care. Tell the provider how the collision occurred and report all symptoms accurately. Do not exaggerate, but do not omit symptoms because they seem minor at first.
- Notify insurers without guessing. Give basic facts needed to report the claim. Avoid speculating about speed, distance, fault, or injuries before the evidence and medical condition are understood.
- Preserve the vehicle and digital evidence. Save dashcam files, photographs, navigation history, tow records, repair estimates, and any vehicle-app data. Do not authorize destruction or major repairs before important evidence is documented.
Texas Transportation Code Chapter 550 contains the principal stop, information-exchange, assistance, and reporting duties after a crash. A practical overview of the immediate process is also available in the first 24 hours after a San Antonio car accident.
What evidence matters most after a confusing interchange crash?
The strongest evidence usually establishes where each vehicle was, which lane continued, which lane ended or merged, and what each driver had time to see and do. Useful sources include scene photographs, damage geometry, witness statements, dashcams, 911 and dispatch records, police video, private surveillance, vehicle event data, and commercial telematics.
Do not wait for TxDOT camera footage. TxDOT expressly states that its live traffic cameras are not recorded, so the agency normally will not have stored video of the collision. Nearby businesses, buses, rideshare vehicles, fleet vehicles, and other motorists may still have recordings, but retention periods can be short.
The Texas Peace Officer’s Crash Report is commonly called the CR-3. TxDOT is the custodian of that report only. TxDOT directs requests for officer dashcam video, body-camera video, field notes, photographs, and other scene materials to the investigating law-enforcement agency.

Attorney Insight
In disputed interchange claims, adjusters often focus on location uncertainty when trying to divide fault. “I was on I-35 near I-10” is usually too vague. A useful record identifies the direction, upper or lower level, travel lane, connector ramp, nearest exit, and position relative to the lane split. That detail can determine which vehicle had to merge, whether lane markings changed, and where private video or agency records should be requested.
What changes if an 18-wheeler or commercial vehicle was involved?
A commercial-vehicle crash may involve additional defendants, insurance policies, regulations, and electronic evidence. The driver and motor carrier are often central, but ownership, dispatch, maintenance, cargo, leasing, and employment records may identify other responsible parties. Early preservation is especially important because vehicle data and company records can be overwritten or lost under routine practices.
Important evidence may include the truck’s electronic logging device, engine control module or event data recorder, road-facing camera, GPS or telematics history, dispatch communications, inspection records, maintenance records, driver qualification materials, and post-crash testing documents. A preservation letter should identify the specific categories of data and vehicles before routine overwriting, repair, sale, or disposal occurs.

Which insurance coverage may apply after an interchange wreck?
Several coverages may apply at the same time, especially in a multi-vehicle collision with serious injuries. Potential sources include the at-fault driver’s liability coverage, an employer or motor carrier policy, your collision coverage, personal injury protection, medical payments coverage, and uninsured or underinsured motorist coverage. Each coverage has its own limits, exclusions, and claim requirements.
Texas requires at least $30,000 in bodily-injury liability coverage per injured person, $60,000 per crash, and $25,000 for property damage. This is called 30/60/25 coverage. Those minimum limits can be inadequate when several people are injured in one chain-reaction crash.
Personal injury protection, commonly called PIP, can pay covered medical bills and certain nonmedical losses such as lost wages regardless of who caused the crash. Uninsured or underinsured motorist coverage, commonly called UM/UIM, can apply when the responsible driver has no insurance or insufficient limits. Texas insurers must provide PIP and UM/UIM unless the named insured rejects the coverage in writing. Actual benefits depend on the policy and claim facts.
How long do I have to file an I-35 or I-10 crash lawsuit in Texas?
Texas generally requires a personal injury lawsuit to be filed within two years after the crash under Texas Civil Practice and Remedies Code § 16.003. Exceptions and different rules may apply, so the two-year period should not be treated as a universal deadline for every person, defendant, or claim.
The practical evidence deadline is often much earlier. Video can be overwritten, vehicles can be repaired, witnesses can become difficult to locate, and commercial data can be lost through routine retention practices. Claims involving governmental units or other special parties may also present separate notice and immunity issues that require prompt review. Texas Civil Practice and Remedies Code § 101.101, for example, contains a notice provision for claims under the Texas Tort Claims Act.
When should I contact a San Antonio car accident lawyer?
Legal review is especially useful when someone is injured, fault is disputed, multiple vehicles are involved, a commercial vehicle caused or contributed to the crash, insurance limits appear inadequate, or an insurer requests a recorded statement or early release. A lawyer can evaluate the lane configuration, preserve evidence, identify policies and responsible parties, review medical documentation, and calculate filing deadlines.

What are common questions about I-35 and I-10 interchange wrecks?
The most common questions concern merge fault, simultaneous lane changes, missing camera footage, police-report conclusions, commercial-truck evidence, and filing deadlines. The answers below provide general Texas rules, but the result in any particular claim depends on the roadway configuration, vehicle movements, injuries, insurance policies, and evidence that can be preserved.
Is the merging driver always at fault in an I-35 or I-10 crash?
No. The merging driver must enter the lane safely and use a signal, but the through driver may share responsibility for speeding, following too closely, distraction, or failing to react reasonably to visible traffic. Texas proportionate responsibility assigns percentages from the full evidence, not merely from which vehicle crossed a lane line.
What if both cars changed lanes at the same time?
Both drivers may bear responsibility. Investigators look at lane markings, impact angles, damage locations, turn signals, vehicle positions, dashcam video, and witness accounts. The exact ramp and travel lane matter because the configuration can change quickly in the downtown I-35 and I-10 corridor, especially around splits and traffic shifts.
Can I obtain TxDOT camera footage of the wreck?
Usually not. TxDOT states that its traffic cameras are used for real-time monitoring and that footage is not recorded. Other video may exist from nearby businesses, buses, trucks, rideshare vehicles, private dashcams, or police vehicles. These sources should be identified quickly because many systems overwrite recordings automatically.
Does the police report decide who is legally at fault?
No. A CR-3 crash report can influence an insurer’s early evaluation, but it does not conclusively determine civil liability. Photos, physical damage, witness testimony, electronic data, roadway design, and later investigation may support or contradict the officer’s initial narrative. A factual error should be documented and addressed promptly.
What should I preserve if an 18-wheeler was involved?
Preserve photographs, witness information, the damaged vehicles, dashcam files, and all identifying information for the driver, tractor, trailer, motor carrier, and USDOT number. A targeted preservation request may also seek electronic logs, engine or event data, telematics, cameras, dispatch records, inspections, maintenance files, and driver qualification records.
How long do I have to sue after an interchange crash in San Antonio?
Texas generally provides two years to file a personal injury lawsuit, but exceptions may alter that deadline and some parties may trigger earlier notice requirements. Evidence can disappear long before two years passes. Prompt investigation is particularly important when video, commercial vehicles, changing construction layouts, or disputed lane movements are involved.
