After a traffic collision, take a possible concussion seriously: seek prompt medical evaluation, preserve the facts and records, and get legal guidance before an insurer’s questions or deadlines put you at a disadvantage. Only a qualified clinician can diagnose an injury, and a concussion cannot be confirmed from symptoms alone. This article provides general legal information, not case-specific advice.
Emergency warning: Call 911 or go to an emergency department right away for a worsening headache, repeated vomiting, seizure, weakness or numbness, slurred speech, unequal pupils, escalating confusion, or an inability to wake. These signs can require urgent care after a head impact.
A traffic collision can jolt the head and body even when there is no visible wound, no airbag deployment, or no loss of consciousness. A person may later report a headache, dizziness, nausea, fatigue, vision changes, sensitivity to light or noise, trouble concentrating, memory concerns, feeling foggy, irritability, or sleep changes.
Symptoms do not all arrive at the scene. They may appear hours or days later, and their timing can make it harder to connect what a person is feeling to the collision. That is one reason a prompt, accurate account of the crash and later symptoms can matter. It is also why a person should not dismiss new or changing concerns simply because they initially felt able to leave the scene.
The CDC’s concussion signs and symptoms guidance explains that symptoms can affect how a person feels, thinks, acts, or sleeps, and it identifies danger signs that call for emergency care. For a separate medical overview of concussion causes and symptoms after a sudden acceleration or deceleration, see Mayo Clinic’s concussion information.
Medical records are not merely paperwork for a claim. They may show when a concern was reported, what the clinician observed, and how the collision was described. They do not decide fault by themselves, but they can be important evidence when the injury is not obvious in a photograph.
As soon as it is safe, keep the facts in one place. Save photographs of vehicle damage and the scene, the other driver’s information, names and contact details for witnesses, and any collision-report number. Keep copies of communications from insurers, repair estimates, receipts, time missed from work, and records you receive from medical providers.
A short personal timeline can also help. Note the collision date and time, where you were seated or standing, what you remember about the impact, when symptoms began, and how they affected ordinary activities. Keep it factual. Do not guess about the other driver’s conduct or diagnose yourself. If your memory changes or you recall a new detail, mark when you recorded it rather than revising an earlier entry without explanation.
An insurance adjuster may ask for a recorded statement, medical authorization, or quick description of what happened. You can be polite without speculating. If you do not know an answer, say so. A collision claim often turns on evidence such as statements, photographs, vehicle damage, available video, reporting records, and documentation of losses. The facts of each crash determine which evidence is available and relevant.
Do not assume that a normal appearance at the crash scene answers every medical or legal question. A person can have symptoms later, and a claim may involve disagreement over causation, the severity of harm, prior health history, fault, or insurance coverage. A legal review can help identify what information should be preserved and what questions should be answered carefully.
If you need to discuss the legal side of a collision, an attorney can review the circumstances and explain the next steps for your situation. No lawyer can promise a settlement or a particular result.
Have collision records or insurer questions?
Ask for a factual review of your Arizona traffic-collision claim before you make assumptions about what should happen next.
Arizona’s Department of Public Safety offers an online citizen report for certain minor collisions, but its limits are important. The online tool is for a collision within DPS jurisdiction on a state highway, with no injuries, total estimated damage below $2,000, and no more than two vehicles. It is not a substitute for a crash investigation, and the resulting report number does not lead to further investigation to determine fault, obtain insurance information, or locate a vehicle.
When an injury is suspected or symptoms arise after the event, do not treat the minor no-injury online process as a complete record of the situation. Review the Arizona DPS Citizen’s Collision Report rules to understand the eligibility limits. If emergency conditions exist, use emergency services rather than an online form.
Arizona generally gives an injured person two years after a claim accrues to bring a personal-injury action. That general rule has exceptions, and the deadline may depend on facts that are not apparent from a first conversation. Claims involving a government entity, a minor, a death, or another special circumstance can raise additional timing issues. Waiting can also make it harder to locate witnesses, preserve video, or obtain reliable records.
The governing statute is Arizona Revised Statutes § 12-542. Reading the statute is useful, but it is not a substitute for advice about a particular claim. An attorney can assess the applicable deadline based on the actual facts and parties involved.
It is sensible to separate the medical question from the legal question. A clinician addresses whether an injury is present; an attorney can assess whether there is a claim, what evidence may matter, and how Arizona rules apply. Those questions deserve careful, timely attention without promises about either health or a legal outcome.
Reported result:
Phillips Law Group attorney Montana Thompson secured a $250,000 Phoenix traffic-collision settlement involving a reported concussion.
Past results do not guarantee a similar outcome.
Bring what you have, even if the file is incomplete. Useful items may include a collision report number, photographs, witness information, insurance correspondence, vehicle information, work-loss information, and medical records or billing documents already in your possession. A personal injury lawyer in Arizona can explain which items may be useful and which issues require follow-up.
Be ready to describe the crash in plain language, including what you remember before and after impact and when symptoms were first noticed. Give a full and honest account, including facts that feel uncertain. Accuracy protects the value of the consultation more than trying to make the facts fit a conclusion.
For many people, the first priority is understanding what happened and what information should not be lost. A focused legal conversation can clarify process questions while you continue to follow qualified medical guidance. It cannot replace medical evaluation, and this general information is not case-specific advice.
