Liability in a Texas Accident

Primary Item

In a Texas accident, liability depends on who acted carelessly, whether that carelessness caused your injuries, and how much blame each person carries. That last question often decides what a serious injury claim is worth. While you are still in treatment, the other side’s insurer may already be building a version of the crash that shifts more fault onto you.

At Garcia, Garcia & Mullen Criminal Defense & Injury Lawyers, we answer those fault arguments with evidence from the scene, the vehicles, and the records that follow a collision. If someone is already pointing at you after a crash that left you seriously hurt, our team can review how responsibility is likely to be divided in your case.

What Has to Be Proven Before Liability Is Determined

Most accident claims rest on negligence, the legal term for failing to use reasonable care. Under the framework the state’s courts apply, the injured person must show the other party had a legal duty, breached that duty, and caused the injury through that breach. For example, every driver has a duty to stop at a red light, and running one breaches that duty.

In Werner Enterprises v. Blake, the state’s highest court held in 2025 that negligence must be a substantial factor in causing an injury. In that case, a pickup lost control on ice, crossed a 42-foot median, and hit an 18-wheeler before its driver could react. Even assuming the truck was going too fast for the ice, the court found the pickup’s loss of control was the sole legal cause.

Defense lawyers use that reasoning to call their client’s mistake mere background. We tie each careless act to the specific injuries it produced.

How Fault Percentages Are Assigned in Texas

Fault is rarely all or nothing, and how it is divided controls how much compensation remains available.

Who Receives a Percentage of Fault

Under the state’s proportionate responsibility law, the factfinder, usually a jury, assigns each person who caused or contributed to the harm a whole-number percentage of responsibility. This includes the injured person, each defendant, anyone who has settled, and any responsible third party the court designates. The statute also bars a question about anyone’s conduct without sufficient evidence to support it.

Insurers float fault theories in negotiation that they could never support at trial, and we hold them to that proof.

The 50% Line and How Your Share Reduces Compensation

An injured person cannot recover damages if found more than 50% responsible. At 50% or less, the court reduces the damages by that person’s own percentage and then subtracts any settlement amounts already received.

If a jury values your losses at $200,000 and assigns you 20% of the fault, your recovery drops to $160,000 before settlement credits. An even split still allows recovery of half, but at 51% the same verdict produces nothing.

Collision cases bring their own fault disputes, and our car accident practice page covers how those arguments unfold.

When One Defendant Can Be Made to Pay the Full Award

Each defendant usually pays only its own share. A defendant found more than 50% responsible is jointly and severally liable, which means you can collect the full recoverable amount from that one defendant.

In multi-party cases, finding that a trucking company or other business carries more than half the fault can matter more than the other percentages.

Who Else Can Share Liability in a Texas Accident

The driver who hit you is not always the only party whose conduct counts. Depending on the facts, responsibility may extend to several others:

  • Employers: A business can be held responsible for an employee’s negligence when the employee was acting within the course and scope of the job. This vicarious liability often centers truck accident claims against carriers.
  • Alcohol providers: A bar or restaurant can share liability if it was apparent the customer was obviously intoxicated to the point of presenting a clear danger to themselves and others. That intoxication must also be a proximate cause of the damages.
  • Government entities: A city, county, or state agency must receive notice of a claim within 6 months of the incident. City charters can set their own notice periods, so we check the local rules immediately.
  • Product manufacturers: The fault percentage system also covers harm caused by a defective or unreasonably dangerous product, such as a failed brake component or tire.

Identifying each of these parties early matters, because anyone left out of the case can still be blamed later.

If more than one company or driver may share the blame, call (214) 214-1000 so we can identify each of them before the evidence disappears.

How Defendants Try to Shift Fault Onto You

Shifting even 10 points of fault onto you can cost thousands of dollars, and defense teams use specific legal tools to do it.

Responsible Third Party Designations

A defendant can ask the court to designate a responsible third party, allowing the jury to assign fault to someone not a party to the lawsuit. That motion generally must be filed at least 60 days before trial. A designation does not, by itself, make that person liable to you.

Its real purpose is to shrink the share left on the defendant in the courtroom. We object to weak designations and, once discovery shows nothing behind one, ask the court to strike it.

Seat Belt Evidence

The state's highest court has held that relevant evidence of seat belt use or nonuse is admissible when apportioning responsibility in civil lawsuits. The rule reaches conduct before a crash that caused or contributed to the injuries themselves.

That opens the door for insurers to argue an unbelted driver or passenger caused part of their own harm. We answer with medical and engineering evidence about what a belt would and would not have changed.

The Evidence We Use to Prove Liability

Fault percentages follow the evidence, and the strongest evidence disappears fastest. Our personal injury team at Garcia, Garcia & Mullen typically works through the following:

  1. Vehicle data: We move to preserve event data recorders and other onboard records before a damaged vehicle is repaired or salvaged.
  2. Video footage: Traffic, business, and dashcam recordings can be overwritten quickly, so we request them right away.
  3. The crash report: We compare the officer’s narrative and diagram against the physical evidence instead of accepting its conclusions.
  4. Witness accounts: We locate and interview witnesses while their memories are still fresh.
  5. Reconstruction: When speed, angles, or timing are disputed, we work with reconstruction experts to show how the collision unfolded.
  6. Medical records: Treatment records tie each injury to the crash, and many defendants focus their causation arguments here.

Each step feeds the percentage a jury, or an adjuster predicting a jury, will eventually assign.

Timing matters for another reason. A personal injury lawsuit generally must be filed no later than 2 years after the day the cause of action accrues, a legal term for when the claim comes into existence. Waiting also erodes evidence long before that deadline.

Frequently Asked Questions About Liability in Texas Accidents

Does the police report decide who is liable for my Texas accident?

No. The report is one piece of evidence, and we test the officer’s conclusions against video, vehicle data, and witness accounts.

Can an apology at the scene be used to blame me for the crash?

Insurers often cite apologies and offhand remarks when arguing about fault. Keep conversations at the scene to safety and contact details.

How does dashcam or phone video affect who is found at fault?

Video can resolve disputes about lane position, signals, and timing that witnesses remember differently. Send us any footage you have.

Should I give the other driver’s insurer a recorded statement about fault?

Talk with us first. Adjusters use recorded statements to find admissions that increase your percentage of responsibility, and those statements are hard to retract.

Who decides fault if my injury claim settles without a trial?

No one formally decides it because a settlement is negotiated. Adjusters estimate how a jury would divide responsibility, so the evidence we gather shapes the offer.

Can gaps in medical treatment affect causation?

Gaps give insurers room to argue that something other than the crash caused your condition. Consistent treatment records help tie each injury to the collision.
