How Is Fault Determined in a Car Accident in Irving?
Texas follows a modified comparative fault system. Under Texas Civil Practice and Remedies Code § 33.001, you can recover damages as long as you are not more than 50% responsible for the crash. If you are found 30% at fault, your compensation is reduced by 30%. If you are found 51% or more at fault, you recover nothing. That single rule shapes everything that happens after a collision on Irving roads.
Fault determination starts with the police report. When officers respond to a crash on State Highway 183 or Loop 12, they document road conditions, vehicle positions, witness statements, and any citations issued. That report is not legally binding, but insurance adjusters treat it as their starting point. From there, each insurer runs its own investigation — reviewing photos, traffic camera footage, and physical damage patterns to assign a fault percentage to each driver.
What most people don’t realize is that fault percentages are negotiated, not handed down by a judge in most cases. An adjuster’s initial assessment is not final. Evidence gathered in the first 48 hours — dashcam footage, surveillance video from nearby businesses, skid mark measurements — can shift those percentages significantly. Dashner Law Firm | Irving Injury & Accident Attorney handles cases across the Dallas-Fort Worth area and has seen adjusters reverse fault assignments entirely when new evidence surfaces.
What Evidence Carries the Most Weight in a Texas Fault Investigation?
Physical and digital evidence outweighs witness memory in almost every case. Here is what actually moves the needle.
Traffic camera footage from the Texas Department of Transportation and the City of Irving’s own traffic management systems can capture the exact moment of impact. This footage is often overwritten within 30 days, sometimes sooner. Requesting it immediately — through a preservation letter — is one of the first things an experienced car accident lawyer does.
Vehicle Event Data Recorders (EDR), sometimes called black boxes, log speed, brake application, steering input, and seatbelt status in the seconds before a crash. Under Texas law, this data belongs to the vehicle owner, but accessing it requires specialized equipment. Not every shop has it. Reconstruction engineers and attorneys with access to certified technicians can pull this data and use it to contradict an at-fault driver’s version of events.
Cellphone records are increasingly important. Texas banned handheld phone use while driving statewide in 2017. If a driver ran a red light on Belt Line Road and was on the phone, subpoenaed records can prove it. Insurance companies do not volunteer to pull those records. A car accident attorney who knows the discovery process can compel production.
Photographs from the scene tell their own story. The point of impact on a vehicle reveals the angle of the collision. Damage to the front of one car and the rear quarter panel of another tells a different story than a straight rear-end hit. Adjusters are trained to read these patterns. Your attorney needs to be too.
Does Texas Law Treat Rear-End Collisions Differently From Other Crashes?
There is a common misconception that the trailing driver is always at fault in a rear-end collision. Texas law does not work that way. The trailing driver carries a rebuttable presumption of negligence — meaning the burden shifts to them to show the lead driver acted in a way that contributed to the crash. That presumption can be overcome.
Sudden, unprovoked braking with no mechanical reason, cutting off another vehicle, reversing unexpectedly, or brake lights that are not functional can all assign partial or full fault to the lead driver. On Irving’s service roads near the Las Colinas corridor, these situations come up more than people expect, particularly during construction zone slowdowns.
If you were rear-ended and the other driver’s insurer is trying to assign you partial fault for a lane change, that argument has real consequences under Texas’s comparative fault rules. A 20% fault assignment on a $100,000 claim costs you $20,000. Fighting that assignment matters.
How Does Dashner Law Firm Investigate Fault Differently Than an Insurance Adjuster?
An insurance adjuster’s job is to close claims efficiently. That is not a criticism — it is simply the structure of the role. Their investigation serves the company’s financial interest. Your investigation needs to serve yours.
At Dashner Law Firm | Irving Injury & Accident Attorney, the fault investigation process typically involves retaining an independent accident reconstructionist, not just reviewing the police report. Reconstructionists use vehicle damage analysis, roadway measurements, and physics to produce a report that can be submitted as expert testimony. Insurers take that seriously in a way they do not take a claimant’s phone call.
The firm also works with investigators who canvas the area for business security cameras that captured the crash. A convenience store two blocks from the intersection may have footage the police never asked for. That kind of ground-level work is what separates a strong fault argument from a weak one.
For legal context on how negligence standards apply in personal injury cases, resources from Cornell Law School and Justia provide solid background on comparative fault doctrine. The American Bar Association also publishes guidance on how attorneys approach evidence gathering in motor vehicle cases.
Can a Driver Be Found at Fault Even Without a Traffic Citation?
Yes, and this happens regularly. A citation means a police officer saw enough probable cause to issue it. The absence of a citation does not mean the other driver was driving carefully. Negligence and criminal or traffic violation are separate standards.
In Texas, negligence means a driver failed to act as a reasonably careful person would under the circumstances. Drifting into another lane because of distraction, following too closely, or failing to check mirrors before merging can all constitute negligence without a single citation being written. Proving it requires the evidence described above — video, EDR data, witness accounts, and expert analysis.
This distinction matters in Irving cases where crashes happen on complex interchanges or access roads where fault is genuinely ambiguous and officers don’t always issue citations at the scene. The civil standard for fault — preponderance of the evidence, meaning more likely than not — is lower than the criminal standard. You do not need proof beyond a reasonable doubt to win a civil claim.

What Happens When Both Drivers Dispute Fault and There Are No Witnesses?
This is the most difficult scenario, and it comes up more than people admit. Two drivers, two conflicting stories, no camera footage, no bystanders. The investigation falls back on physical evidence and expert interpretation.
Vehicle damage patterns, final rest positions, and debris fields tell a mechanical story that is often more reliable than memory. Accident reconstructionists trained in forensic analysis can model the crash and estimate speeds, angles, and points of impact from physical evidence alone. Their conclusions are not infallible, but they carry real weight with insurance companies and juries.
If the case cannot be resolved through negotiation, it goes to litigation. Texas courts give juries the task of weighing conflicting evidence and assigning fault percentages. Having an experienced car accident lawyer who has tried cases in Dallas County and Tarrant County courts makes a practical difference in how that evidence is presented. Attorneys who primarily settle cases and rarely go to trial sometimes accept unfavorable fault allocations rather than litigate. That is worth asking about when you choose representation.

The two-year statute of limitations under Texas Civil Practice and Remedies Code § 16.003 gives most crash victims until the second anniversary of the accident to file suit. That sounds like plenty of time, but evidence disappears, witnesses become unreachable, and camera footage gets overwritten. Starting early is not just a good idea — it is often the difference between a provable case and one that stalls.
If you were in a crash in Irving and fault is genuinely disputed, get an attorney involved before you give a recorded statement to the other driver’s insurer. That statement can and will be used to assign you a higher fault percentage.
