The moment a crash happens, evidence starts disappearing. Skid marks wash away in the next rainstorm. Business surveillance systems overwrite footage within 48 to 72 hours. Witnesses forget details, fill in gaps, or become impossible to locate. By the time an insurance adjuster calls to take your statement, the physical record of what actually happened may already be incomplete.
What makes a Dallas car accident claim succeed isn’t just having evidence. It’s having the right evidence organized around what the law requires you to prove, and having someone who can interpret it when the other side pushes back. At Marchand Law, our team includes a former nurse and a former engineer. That background changes how we read medical records, black box data, and accident reconstruction findings. We treat them not as documents to file, but as arguments to build.
What You Need to Prove to Win a Dallas Car Accident Claim
Texas negligence law requires proving four things: duty, breach, causation, and damages. Duty means the other driver had a legal obligation to operate their vehicle safely. Breach means they failed to meet that obligation. Causation means that failure caused your injuries. Damages means you suffered measurable harm. Each element must be supported by a preponderance of the evidence, meaning the evidence makes it more likely than not that the other driver was at fault.
Texas Civil Practice and Remedies Code Section 33.001 adds another layer. Under Texas’s modified comparative negligence rule, a claimant found more than 50 percent responsible for a crash recovers nothing. Below that threshold, any damages awarded are reduced by the claimant’s percentage of fault. This means evidence in a Dallas car accident claim has two jobs: prove what the other driver did wrong, and prevent fault from being shifted onto you.
Scene Evidence That Establishes Fault
Photos and video taken at the scene are among the most durable forms of evidence available. Vehicle positions, the direction and severity of damage, skid marks, road conditions, traffic signals, and any visible hazards all tell a story that’s difficult for an adjuster to rewrite weeks later. Take photos from multiple angles and distances, and photograph any damage to barriers, signs, or other objects involved in the crash.
Damage patterns alone can carry significant weight. Rear-end damage typically points to the trailing driver’s fault, since a driver following at a safe distance generally has time to brake. Side-impact damage often indicates a red-light or right-of-way violation. These patterns support fault arguments before any witness has said a word.
Witnesses who saw the crash from a neutral vantage point become critical when the drivers tell conflicting stories. Get names and contact information before people leave the scene. A witness’s account taken the same day carries far more weight than one collected two weeks later, after memory has filled in the gaps.
Digital & Technical Evidence Insurers Can’t Easily Dispute
Video evidence is often the closest thing to an objective witness. Dashcam footage, traffic camera recordings, and surveillance from nearby businesses can capture the collision directly. The problem is that most of these systems overwrite automatically. A dashcam may loop every few hours, and a business’s exterior cameras often overwrite within two to five days. Acting quickly to preserve this footage, through a formal preservation letter or legal hold request, can be the difference between having it and losing it.
An event data recorder, commonly called a black box, is embedded in most modern vehicles and records data in the seconds before and during a crash. Speed, braking force, throttle position, and steering input are all captured. This data can directly contradict a driver’s claim that they were going the speed limit or had already applied the brakes. Extracting and interpreting that data requires specific tools and knowledge. Our engineering background lets us evaluate it directly rather than relying on an outside vendor to explain it before we can explain it to a jury.
Accident reconstruction combines physical evidence, black box data, and engineering principles to model how a crash occurred. The findings can establish speed, point of impact, and driver behavior with a level of precision that photographs alone can’t achieve.
How to Get Your Official Dallas Crash Report
The Texas Peace Officer’s Crash Report, known as the CR-3, is the official document prepared by the responding officer. It includes the officer’s assessment of contributing factors, vehicle positions, and any citations issued. It’s not the final word on fault, but it’s a starting point insurers take seriously.
How you obtain it depends on who responded to your crash:
- Dallas Police Department: For crashes within Dallas city limits, request the CR-3 from the Dallas Police Department’s Open Records Unit at 1400 Botham Jean, Dallas, TX 75215. The fee is $6, and reports are typically available 5 to 7 business days after the accident.
- Dallas County Sheriff’s Office: For crashes in unincorporated parts of Dallas County handled by the Sheriff, reports can be obtained in person at the Frank Crowley Courts Building, 133 North Riverfront Boulevard, Dallas, or through the TxDOT CRIS online portal.
- TxDOT CRIS Portal: The Texas Department of Transportation’s Crash Records Information System (CRIS) offers statewide access. Reports are generally available through CRIS about 14 days after the crash. Because crash reports are confidential under Texas law, they aren’t publicly viewable online without a purchase through an authorized system.
Evidence That Proves the Value of Your Injuries & Losses
Proving fault gets you to the table. Proving damages determines what you recover. These are separate elements, and both need documentation.
Medical records are the foundation of a damages claim. Emergency room notes, diagnostic imaging results, specialist evaluations, and ongoing treatment records create a documented chain connecting the crash to your injuries. Without that chain, an insurer will argue the injury predated the crash, was minor, or isn’t supported by objective findings.
Lost income claims require the same level of documentation. Pay stubs, W-2 forms, tax records, or a letter from your employer establishing your pre-crash earnings and the time you’ve missed all substantiate what you’ve lost. Self-employed claimants may need to rely on tax returns or financial statements.
Our nursing background shapes how we read medical records in these cases. We look for whether the documentation clearly establishes a causal link between the crash mechanism and the diagnosed injury, whether the treatment timeline is consistent with the type of injury claimed, and whether any gaps in the record need explanation before they become a problem at trial.
Evidence Mistakes That Undermine a Claim
Gaps in medical treatment are one of the most common ways a strong claim loses value. If a week passes between the crash and your first medical visit, or if you stop treatment before reaching maximum medical improvement, insurers will argue the injury wasn’t serious or was caused by something else. Consistent treatment creates a consistent record.
Recorded statements given to an insurance adjuster before your treatment is complete carry real risk. Adjusters are trained to ask questions that elicit answers they can use to shift blame under Texas’s modified comparative negligence framework. An offhand comment about checking your phone, feeling distracted, or not seeing the other car can reduce your recovery or eliminate it entirely. You’re not required to give a recorded statement to the other driver’s insurer.
Delays in requesting surveillance footage or the official crash report can cost you evidence that can’t be recreated. Businesses have no obligation to hold footage, and spoliation (the loss or destruction of potentially relevant material) is far harder to address after the fact than to prevent with a timely preservation request.
Putting the Evidence Together
The strongest claims combine thorough documentation with the ability to interpret what that documentation means. Photos and medical records matter. So does understanding what black box data reveals about a driver’s behavior, or whether a gap in treatment reflects the nature of the injury rather than indifference to it. Those distinctions can define what a claim is worth.
