Insurance companies do not pay claims because something unfair happened. They pay claims that can be proven. The difference between a file that settles well and one that settles for very little usually has nothing to do with how serious the injury was, and everything to do with what somebody bothered to collect in the first few weeks.
Most of the evidence that matters most has a shelf life measured in days.
Evidence From the Scene
If you are physically able, or if someone with you is, collect this before anything gets moved.
Photographs of every vehicle from multiple angles, including undamaged sides. Wide shots showing the position of the vehicles, lane markings, traffic controls, and skid marks. The other driver’s license, registration, and insurance card. Photographs of the roadway surface, weather conditions, lighting, and any obstruction that blocked a sight line. Visible injuries, photographed the same day and again as bruising develops.
Names and phone numbers for every witness. Independent witnesses are the most valuable and the most easily lost, because once they drive away there is usually no way to find them again.
In a fall case, photograph the hazard itself before it gets cleaned up, along with the surrounding area, the lighting, and any warning signs that were or were not present. That evidence is the whole case in most premises liability claims.
Our guide on what to do immediately covers the sequence in more detail, including Arizona’s reporting requirements.
The Police Report
A crash report is not admissible as proof of fault at trial in most circumstances, but it drives the entire claims process anyway. Adjusters read it first, and a report that assigns a citation to the other driver changes the tone of every conversation that follows.
Where you request it depends on which agency responded. Collisions inside city limits go through the Yuma Police records bureau. Crashes in unincorporated areas go through the Yuma County Sheriff. Minor collisions on state highways can be submitted through the DPS reporting tool, which generates a report number insurers often require.
Read the report as soon as you get it. Diagrams and narratives contain errors, and corrections are far easier to pursue while the officer still remembers the call.
Medical Records Are the Backbone
No document in the file carries more weight. The medical record establishes that you were injured, when, how badly, and whether the injury connects to the accident.
Three habits protect that record. Get examined promptly, because gaps between the incident and the first visit are the most common argument against causation. Report every symptom at every visit, including the minor ones, since undocumented complaints tend to be treated as complaints that never existed. And complete the treatment plan, because missed appointments get read as recovery.
Collect the bills alongside the records. Together they build the foundation for the damages you claim, and neither half works without the other.
Evidence That Disappears
This is where claims are quietly lost.
Surveillance footage from stores, parking lots, and traffic cameras is typically overwritten on a loop that can run as short as a week. Retrieving it requires a preservation demand sent to the right party before the cycle turns.
Commercial vehicle data is worse. Engine control modules, electronic logging devices, dispatch records, and driver qualification files are all subject to routine destruction schedules. In truck accident claims, a spoliation letter needs to go out within days, not months.
Vehicles get repaired or sold for salvage, which destroys the physical evidence a reconstruction depends on. Cell phone records require preservation requests. Roadway debris and skid marks are gone after the next rain.
None of this waits for you to finish treating.
Proof of What You Lost
Medical bills are the easy part. The rest requires assembly.
Pay records and employer statements documenting missed time. Tax returns and profit and loss statements if you are self employed. A vocational assessment if the injury limits what you can earn going forward. Receipts for mileage, equipment, and household help you had to hire.
For the losses with no invoice, a dated journal is the most useful document most clients never keep. Short entries about what you could not do, written as it happens, carry more credibility than a summary reconstructed two years later.
Evidence That Defeats a Blame Shift
Because Arizona reduces recovery by your own percentage of fault, evidence that rebuts a blame shifting theory is worth real money. Black box and telematics data. Signal timing records. Citation history. Scene measurements taken before anything was disturbed.
The same material also helps identify everyone who is responsible, which matters in Arizona because each defendant pays only its own share and an unidentified party’s share may never be collectible.
What Not to Do
- Do not post about the accident, your injuries, or your activities on social media. Defense investigators look, and a photograph of you at a barbecue becomes an exhibit.
- Do not give a recorded statement before you understand your own injuries. Do not sign a blanket medical authorization that opens your entire history rather than the relevant records. Both of those are standard requests, and both are covered in our guide to dealing with adjusters.
- Do not repair or dispose of the vehicle until someone has documented it.
