Texas comparative fault and the 51% rule
Reviewed by Nolan Ryan McConville, Texas attorney since 2016 · Updated October 2026
After a crash, insurance adjusters often say something like, "You were partly at fault too." In Texas, that statement is not just conversation. It can directly change how much you recover, or whether you recover at all.
Here is how Texas comparative fault works, why the 51% line matters so much, and what you can do when an insurer tries to shift blame onto you.
The rule
The basic rule
Texas uses modified comparative fault, also known in Texas as proportionate responsibility (Tex. Civ. Prac. & Rem. Code ch. 33).
50% or less
You can recover damages only if you are 50% or less at fault.
More than 50%
If you are found more than 50% at fault, you recover nothing from the other parties.
Why it's the 51% rule
At 50%, you can still recover. At 51%, you cannot. That is why people call it the 51% rule.
Reductions
How your share reduces the recovery
If you are found partly at fault but 50% or less, your recovery is reduced by your percentage. These examples use made-up numbers and $100,000 in damages.
0% at fault
You can recover the full $100,000.
20% at fault
Your recovery is reduced to $80,000.
50% at fault
Your recovery is reduced to $50,000.
51% at fault
You recover nothing.
- Your damages are $100,000 and you are 0% at fault: you can recover the full $100,000.
- Your damages are $100,000 and you are 20% at fault: your recovery is reduced to $80,000.
- Your damages are $100,000 and you are 50% at fault: your recovery is reduced to $50,000.
- Your damages are $100,000 and you are 51% at fault: you recover nothing.
Percentages
Who decides the percentages
If a case goes to trial, the jury decides. Most cases settle, so in practice the percentages are argued during negotiation.
The jury's role
Jurors hear the evidence and assign a percentage of responsibility to each person or company whose conduct contributed to the harm.
Adds up to 100%
Those percentages have to add up to 100%.
In negotiation
The insurer's view of fault shapes its offer, and your evidence is what pushes back.
Insurer tactics
Why insurers argue about fault
Every percentage point of fault the insurer can put on you reduces what it pays, and getting you over 50% ends its exposure entirely. So adjusters look for anything that suggests you contributed.
Driving choices
Speeding, even a little, a late lane change or a rolling stop.
Phone use
Using a phone around the time of the crash.
Seat belts and helmets
Not wearing a seat belt or helmet, which can be argued in connection with damages.
Your own words
Statements you made at the scene or to an adjuster, such as "I didn't see them."

Multiple parties
Fault can be shared among several parties
Comparative fault is not only about you and one other driver. Fault can be spread among several people and companies.
Common examples
A multi-vehicle pileup on I-635, a crash involving a commercial truck or a fall on a poorly maintained property.
More coverage
Identifying every responsible party can mean more insurance coverage.
Pointing at others
Defendants may point to others, including people not in the lawsuit, to reduce their own share.
Careful investigation
A careful investigation helps make sure the percentages reflect what actually happened.
Riders and walkers
Pedestrians, cyclists and motorcyclists
Fault arguments come up often when the injured person was walking, riding a bike or riding a motorcycle. Those arguments are sometimes made with little evidence behind them.
Outside a crosswalk
Insurers may claim a pedestrian was outside a crosswalk.
Hard to see
Insurers may claim a cyclist was hard to see.
Going too fast
Insurers may claim a motorcycle rider was going too fast.
Helmet rules
Texas riders 21 and older may ride without a helmet if they have completed a safety course or carry the required medical insurance. Helmet use can still come up in arguments about damages.
Evidence
Evidence that answers fault arguments
A strong answer to a fault argument is evidence gathered early.
- Photos and video of the scene, the vehicles and the traffic signals.
- Business, traffic and dashcam video, which can be lost quickly.
- Vehicle event data and, in truck cases, ELD records.
- Independent witnesses.
- The Texas Peace Officer's Crash Report (CR-3) and the officer's notes.

Your words
What to avoid saying
After a crash, it is natural to apologize or say you are not sure what happened. But insurers can use those words later to argue you accepted blame.
Facts with police
Stick to the facts with police.
Recorded statements
Be careful about giving a recorded statement to the other driver's insurer before you understand your claim.

Wrongful death
Comparative fault in wrongful death cases
The same rules apply when a family brings a wrongful death claim.
Reduced recovery
The deceased person's share of fault, if any, can reduce the family's recovery.
Over 50% bars it
A share above 50% can bar the claim.
A full investigation
That puts a heavy burden on the family to make sure the facts are investigated fully, since the person who died cannot tell their side.
Partial fault
Do not assume you have no case
Many people decide they have no claim because they think they were partly to blame.
Not an automatic bar
Under Texas law, being partly at fault does not automatically bar a claim.
A reduced amount
Unless your share is more than 50%, you may still be able to recover a reduced amount.
The first version
The first version of events, from you or from an insurer, is not always the full story.
