A T-bone collision is one of the most violent types of crashes on the road. When a driver blows through a red light at speed and slams into the side of your car, the force hits you where your vehicle has the least structural protection. If this happened to you at an Austin intersection, you are probably dealing with a totaled vehicle, serious injuries, and a stack of medical bills — all while trying to figure out who is responsible and what your options are.

This 2026 guide walks through how liability gets determined in red-light T-bone crashes in Texas, what evidence matters most, and what steps to take to protect your motor vehicle accidents claim. Kelley Wolff Injury Attorneys | Austin Accident Lawyers handles exactly these kinds of cases, and we have seen how quickly the facts in an intersection crash can get complicated when insurance companies get involved.

How Texas Law Determines Fault in a Red-Light Intersection Crash?

The short answer is yes — the driver who ran the red light is liable. But the legal path from “they caused the crash” to “you receive compensation” involves more steps than most people expect.

Texas follows a modified comparative fault rule under Texas Civil Practice and Remedies Code § 33.001. Under this framework, you can recover damages as long as you are not more than 50% responsible for the accident. Your recovery gets reduced by your percentage of fault. So if a jury finds you were 10% responsible — maybe you were slightly over the speed limit — your damages get reduced by 10%.

Insurance adjusters know this rule well. After a T-bone crash, the at-fault driver’s insurer will sometimes try to spread fault to you, even when the other driver clearly ran a red light. They might argue you could have avoided the crash, that you were speeding, or that your view of the intersection was clear enough that you should have anticipated the other vehicle. These arguments often have no factual basis, but without solid evidence on your side, they can chip away at your claim.

Texas also requires that drivers carry minimum liability coverage: $30,000 per person, $60,000 per accident, and $25,000 for property damage, under Texas Transportation Code § 601.072. In serious T-bone crashes, those minimums often fall far short of actual damages, which is why your own underinsured motorist coverage becomes important. FindLaw has a solid breakdown of how uninsured and underinsured motorist coverage works if you want to check your own policy terms.

What Evidence Do You Need to Prove the Other Driver Ran the Red Light?

This is where intersection crashes get tricky. Both drivers often claim the light was green in their favor. Without independent evidence, it becomes one person’s word against another’s. In 2026, however, there are more sources of objective evidence than ever.

Traffic Camera Footage. Austin has red-light cameras and general traffic monitoring cameras at many major intersections. The City of Austin’s Transportation Department manages much of this infrastructure. Footage gets overwritten quickly — sometimes within 24 to 72 hours — so preserving it requires fast action. An attorney can send a spoliation letter to the relevant city department or TxDOT to preserve that footage before it’s gone.

Event Data Recorders (EDRs). Most modern vehicles have a black box that records speed, braking, throttle position, and other data in the seconds before a crash. The other driver’s EDR can confirm they were traveling at speed and did not brake before impact. Accessing this data requires legal process, but it is often the most damning evidence available. According to Cornell Law School’s Legal Information Institute, EDR data is generally admissible in civil litigation.

Witness Statements. Intersections in Austin tend to have pedestrians, cyclists, and other drivers nearby. A neutral witness who saw the light at the time of impact carries significant weight with insurers and juries.

Skid Mark and Physical Evidence Analysis. A crash reconstructionist can work backward from skid marks, point of impact, and final resting positions to determine speed and direction of travel at the moment of collision.

Police Report. The Austin Police Department crash report will note whether a citation was issued and often includes the officer’s assessment of fault. A citation for running a red light or reckless driving is helpful, though not conclusive on its own.

Can You Also Pursue the Other Driver’s Employer If They Were Working at the Time?

This question comes up more than people expect, and it matters because it can significantly expand the pool of available insurance coverage.

Under the legal doctrine of respondeat superior, an employer can be held liable for an employee’s negligent actions if those actions occurred within the scope of employment. If the driver who T-boned you was making a delivery, driving a company vehicle, or traveling between job sites, their employer may share liability. Commercial vehicle operators — delivery drivers, rideshare drivers, trade workers in company trucks — are common examples. Justia provides a clear explanation of how respondeat superior applies in Texas negligence cases.

Rideshare cases have their own layer of complexity. Uber and Lyft maintain different levels of insurance coverage depending on whether the driver had the app on and was actively carrying a passenger. If the driver was on an active trip, Uber and Lyft carry $1 million in third-party liability coverage. If the app was on but no trip was active, coverage drops substantially.

Commercial trucks and 18-wheelers follow federal and state regulations that go beyond standard auto liability. If a commercial vehicle ran the light and hit you, those cases involve motor carrier insurance requirements, driver logs, and federal safety regulations. Our Austin 18-Wheeler Truck Accident Attorneys handle the specific demands of commercial vehicle crash claims separately from standard auto cases.

What Types of Injuries Are Common in T-Bone Crashes, and How Do They Affect Your Claim?

The side of a vehicle offers far less protection than the front or rear. In a T-bone, the door and a few inches of sheet metal are all that stand between the occupant and the striking vehicle. The CDC identifies side-impact crashes as one of the leading causes of serious occupant injury in vehicle accidents.

Common injuries in T-bone collisions include:

Thoracic and lumbar spine injuries from the lateral force of impact. Rib fractures and internal organ damage, particularly to the spleen and liver on the driver’s left side. Traumatic brain injuries when the head strikes the window or door frame. Shoulder and hip injuries from the seatbelt and door contact. Broken arms and wrists when occupants brace against impact.

Some injuries do not appear immediately. Adrenaline masks pain. Soft tissue damage, internal bleeding, and mild traumatic brain injuries often show up days after the crash. The Mayo Clinic and Johns Hopkins Medicine both document how delayed symptom onset is common in motor vehicle trauma — and insurance companies will use any gap between the crash and your medical treatment to argue your injuries were not caused by the accident. See a doctor the same day or the next day, even if you feel okay.

The type and severity of your injuries directly shape the value of your motor vehicle accidents claim. Medical expenses, lost wages, future care needs, and pain and suffering damages all factor in. Permanent injuries — spinal damage, cognitive impairment, chronic pain — push the value of a claim well above policy limits in serious cases, which is where Austin Personal Injury Attorneys with trial experience become critical.

How Long Do You Have to File a Motor Vehicle Accidents Claim in Texas?

Texas sets a two-year statute of limitations for personal injury claims under Texas Civil Practice and Remedies Code § 16.003. The clock starts on the date of the accident. Miss that deadline and you lose your right to sue, with very limited exceptions.

Two years sounds like a long time. It is not. Here is why it goes faster than you think.

Evidence disappears. Camera footage gets deleted. Witnesses forget details. The other driver’s vehicle gets repaired or junked. Physical evidence from the scene gets cleaned up. The sooner you act, the more of this evidence you can preserve.

Insurance negotiations take time. Many people spend months going back and forth with an insurer before realizing the offer on the table will not cover their actual losses. If that negotiation runs too close to the two-year mark, filing a lawsuit becomes rushed.

If a government entity is involved — say the intersection had a defective traffic signal and you have a claim against the City of Austin — the timeline shrinks dramatically. Texas Government Code § 101.101 requires notice of a claim against a government entity within six months of the incident.

Minor children have their own timeline rules: the statute of limitations does not begin running until they turn 18. Wrongful death claims involving a fatality also carry a two-year window, but they run from the date of death, not always the date of the crash. If you lost a family member in a T-bone collision, Austin Wrongful Death Attorneys can explain how that timeline applies to your specific situation.

What Should You Do Immediately After a T-Bone Crash at an Austin Intersection?

Actions taken in the minutes and hours after a crash either build or undermine your claim. Here is what actually matters.

Call 911 and get a police report. Texas law requires reporting crashes involving injury or property damage above $1,000. Get the report number before you leave the scene.

Document everything you can. Photograph both vehicles, all four corners, the intersection, the signal lights, skid marks, and any debris. Take video if possible. Photograph street signs so the location is clear.

Get witness contact information. People scatter quickly. Names and phone numbers from neutral witnesses can make a claim.

Do not apologize or speculate about fault. Saying “I’m sorry” at the scene gets used against you. Stick to the facts when speaking with police.

See a doctor immediately. Go to the emergency room or an urgent care clinic that day. Tell them exactly how the crash happened and describe every symptom, even minor ones.

Notify your own insurer, but be careful about recorded statements. Your insurer needs to know about the crash. The at-fault driver’s insurer does not need a recorded statement from you — and giving one without legal advice is usually a mistake.

Contact a motor vehicle accidents attorney before accepting any settlement offer. Early offers from insurers are almost always lower than what a claim is actually worth. Learn more about our team and how we approach these cases.
