Evidence in a personal injury case turns your account of an injury into a claim an insurer or court can act on. Without documentation, even a serious injury remains an assertion. In Utah, the proof you gather in the first days often decides what the claim is worth months later.
At Lance Bingham Utah Personal Injury Lawyers, our Salt Lake City attorneys identify, request, and preserve the records that show how an injury happened and what it has cost. Utah applies its own evidence rules, and several of them surprise injured people, including one that keeps a traffic citation out of a civil trial.

Most proof in an injury claim has a shelf life. Surveillance video gets overwritten on a loop, damaged vehicles get repaired or sold for salvage, and roadway conditions change within days.
Our team addresses the time-sensitive material first, then builds out the documentary record around it. That order matters, because a medical bill can be requested next month while a store's camera footage may be gone by Friday.
A preservation letter notifies a business, driver, employer, or insurer to hold specific items because a claim is coming. Generic requests are easy to ignore, so we name the material: the loading dock camera, the tractor-trailer's electronic logs, the vehicle's event data recorder, the property maintenance file.
These letters carry weight because of what Utah courts can do afterward. Under Rule 37 of the Utah Rules of Civil Procedure, a court retains the inherent power to impose sanctions over lost evidence. That power reaches a party who destroys, conceals, alters, tampers with, or fails to preserve a document, tangible item, or electronic data in violation of a duty.
Utah courts have recognized that this duty attaches once litigation is pending or reasonably foreseeable. A preservation letter can help document that a party was placed on notice of a potential claim and the need to preserve relevant evidence.
The summary report an agency hands out is only a fraction of what it holds. Utah defines the term broadly, and that definition changes what we ask for.
Under Utah Code § 41-6a-404, the accident-report file may include the report itself along with accompanying data gathered during the investigation, such as witness information, statements, photographs, video, diagrams, and field notes.
Ordering only the two-page summary leaves the body camera footage, the witness recordings, and the scene photographs sitting in an evidence locker. Our attorneys request the full file.
Injury claims are rarely decided by one document. They are built from several categories of proof that, together, establish who was responsible, how the injury happened, and what it has cost.
Physical evidence captures conditions as they existed at the moment of the incident. Skid marks, debris patterns, a torn stair tread, a missing handrail, a broken product component, and vehicle crush damage all speak to how an event unfolded.
Photograph and video the scene from several angles and distances before anything is cleaned up or repaired. Where the object itself can be kept, keep it, because an engineer may later need to inspect the actual part rather than a picture of it.
Medical documentation is what connects an incident to a diagnosis and a diagnosis to a dollar figure. It also creates the timeline insurers scrutinize most closely.
A complete medical file in an injury claim usually includes:
Gaps in treatment do real damage. When someone stops attending appointments for six weeks, an insurer will argue the injury was resolved or came from something else entirely.
Independent witnesses can be especially valuable because they may provide a neutral account of how the incident occurred. Their accounts can confirm a light was red, a floor was wet, or a hazard had been there for hours.
Memories compress, and contact information goes stale quickly, so names, phone numbers, and email addresses should be collected at the scene.
One detail matters here. Under Utah Code § 41-6a-402, a witness may ask that their address and phone number be excluded from the accident report. Collect that information yourself rather than relying on the officer's paperwork.
Electronic records can provide objective, time-stamped information that helps clarify disputed facts. Vehicle event data recorders capture speed, braking, and throttle position in the seconds before impact. Commercial trucks generate electronic logging device data, and phones generate location and usage records.
Surveillance video from a business, a doorbell camera, or a transit vehicle can settle a disputed fall or intersection collision outright. Most of these systems overwrite themselves within days or weeks, which is why written preservation demands go out early.
Income loss has to be documented, not described. Pay stubs, W-2 forms, tax returns, work schedules, job descriptions, and an employer verification letter convert missed shifts into a calculable figure.
Self-employed and commission-based workers need a different file, typically built from tax returns, invoices, and profit and loss statements across several years. Time away from work also has to be medically supported, so provider documentation and employment records have to align.
Collecting proof is only half the work. Utah decides what a fact finder is permitted to consider, and several of its rules run counter to what injured people expect.
Under Utah Rule of Evidence 401, evidence is relevant if it has any tendency to make a fact more or less probable and that fact is of consequence in deciding the action. That is a deliberately low bar.
Rule 403 supplies the counterweight, allowing a court to exclude relevant evidence when its value is substantially outweighed by unfair prejudice, confusion, or needless repetition. Graphic injury photographs and a defendant's unrelated history are the usual battlegrounds.
This provision catches almost everyone off guard. Utah has an unusual rule among the states, listed in the Utah Rules of Evidence as Rule 416, titled Violation of Traffic Code Not Admissible.
The rule addresses convictions for an infraction or class C misdemeanor under the Utah traffic code. Such a conviction may not be used to prove that the person acted negligently, and it may not be used to attack that person's credibility on those issues.
The practical consequence is significant. If the other driver was cited at the scene and later paid the ticket, that citation is not the proof of fault many people assume it to be.
Fault has to be established through the underlying facts instead: The scene evidence, the vehicle data, the witness accounts, and the reconstruction. Any resource telling you a citation decides your case is describing a different state's law.
Injury cases frequently depend on experts. Accident reconstruction specialists explain how a collision occurred, treating and reviewing physicians address causation and future care, and vocational experts assess lost earning capacity.
Utah does not apply the federal Daubert test that many national resources cite. Utah Rule of Evidence 702 instead requires a threshold showing that the principles or methods underlying the testimony are reliable, based on sufficient facts or data, and reliably applied to the facts of the case.
The rule also states that this threshold is satisfied where the underlying principles or methods are generally accepted by the relevant expert community. Judges still serve a gatekeeping function; the standard is simply framed differently than the federal one.
Utah operates a no-fault automobile insurance system, so your own personal injury protection coverage pays initial medical expenses regardless of who caused a crash. That coverage does not pay for pain and suffering.
Before you may pursue general damages from an at-fault driver, Utah requires proof that your injuries meet a statutory threshold. This is an evidentiary burden that arrives before the fault argument even begins, and it is the reason early medical documentation matters so much in Utah collision claims.
Under Utah Code § 31A-22-309, a person covered by personal injury protection may not maintain an action for general damages arising from an automobile accident unless one or more of the following is present:
Two categories are worth a closer look. A bone fracture qualifies on its own, which many summaries of Utah law leave out entirely.
Permanent impairment must rest on objective findings, meaning imaging, measured range of motion, or clinical testing rather than a description of how you feel. The statute also provides that these limitations do not apply to a person making an uninsured motorist claim.
Insurers may dispute the severity or cause of an injury, but they may also argue that the injured person shares responsibility for the accident.
Utah Code § 78B-5-818 provides that a person's own fault does not by itself bar recovery. Recovery is available from a defendant or group of defendants whose combined fault exceeds the fault of the person seeking recovery.
Read that carefully, because the arithmetic is unforgiving. A person assigned 40% of the fault may pursue a claim reduced by that share, while a person assigned 50% recovers nothing at all.
Percentages are argued from evidence, not opinion. Whether you were 40% or 50% responsible for an intersection collision may come down to a single frame of video, one witness, or the throttle data pulled from a vehicle module. That is the clearest illustration of why documentation matters in a Utah injury claim.
The days immediately following an injury carry the most evidentiary value. Working through the following sequence protects material that cannot be recreated later.
One more precaution belongs here. Set social media aside while a claim is pending, because a single photograph taken out of context can be reframed as proof that an injury was minor.
Several categories of evidence sit with government agencies rather than private parties. Each has its own request channel.
Which agency responded determines where the report lives. Collisions inside Salt Lake City generally route through the city police department. Incidents on state highways and interstates route through the Utah Highway Patrol, which handles crash and police report requests through an online records portal.
Access is restricted. Section 41-6a-404 limits who may obtain an accident report, and people involved in the collision, along with attorneys representing them, are among those who may request one.
Some material falls outside the accident report entirely, including traffic signal timing data, road maintenance and inspection logs, prior complaint records for an intersection, and 911 audio. Those are pursued as records requests.
Utah's Government Records Access and Management Act governs the process, and the Utah State Archives publishes the forms, deadlines, and appeal procedures that apply. Agencies may charge reasonable fees, may classify certain records as private or protected, and must respond within statutory timeframes.
Strong claims are undermined by ordinary, avoidable decisions far more often than by bad luck. These patterns recur constantly:
The injured person carries it. The standard in a civil case is a preponderance of the evidence, meaning your version must be shown to be more likely true than not. That is a lower standard than the one used in criminal cases, but it still requires affirmative proof of duty, breach, causation, and damages.
The report is invaluable for investigation, because it identifies parties, witnesses, insurers, and responding officers. Its use at trial is more limited, and Rule 416 separately keeps a traffic conviction from proving negligence. Treat the report as a roadmap to evidence rather than as the evidence itself.
It varies widely, and many systems retain footage for only 7 to 30 days before overwriting. Some small businesses overwrite in less than a week. Because no general Utah statute requires a private business to retain video indefinitely, a written preservation demand delivered quickly is often the only thing that saves it.
Yes. Posts, photographs, check-ins, and comments are routinely sought during discovery and used to question the severity of an injury. Context rarely travels with a screenshot, so a photograph from a family event can be presented as evidence of full recovery.
Not every claim requires one. Experts become important where causation is disputed, a pre-existing condition is raised, liability is technical, or future medical needs and lost earning capacity have to be projected. Whether an expert helps a particular claim is a case-specific judgment.
Evidence in a personal injury case is easiest to protect early and hardest to reconstruct later. If you were injured in Salt Lake City or anywhere in Utah, our attorneys can review what exists, identify what is at risk, and send preservation demands to the parties holding it.
