Quick Answer
In the first 48 hours after a crash you should get medical attention even if you feel fine, document the scene and your injuries thoroughly, report the accident to your own insurance company, and decline to give a recorded statement to the other driver's insurer until you understand the full extent of your injuries. Nearly every mistake that damages an injury claim happens inside this window.
The decisions are not complicated, but they are time-sensitive. Evidence disappears, witnesses become unreachable, and symptoms that seem minor on day one can become the center of your medical file by day four.
Your First 48 Hours Checklist
- Call 911 and get a police report, even for a minor-looking collision
- Say you're "not sure yet" and need evaluation — never "I'm fine"
- Photograph both vehicles, plates, the scene, and any visible injuries
- Collect witness names and phone numbers before they leave
- Get medical care the same day, and report every symptom
- Report the crash to your own insurer within 24 hours
- Decline a recorded statement to the other driver's insurer
- Preserve your vehicle — don't repair, sell, or scrap it yet
- Start a daily log of pain, missed activities, and sleep quality
- Skip social media until the claim is resolved
Why These Two Days Matter So Much
Roughly 2.42 million people were injured in traffic crashes in the United States in 2024. Most of them made decisions in the first hours after impact that quietly shaped everything that followed: whether an injury was documented, whether fault was recorded accurately, whether a statement was taken while they were still in shock and unable to assess their own condition.
Adrenaline masks pain. Soft-tissue injuries, concussions, and disc injuries frequently take 24 to 72 hours to become symptomatic, which is why so many people tell an officer they are fine and wake up two days later unable to turn their head. An insurance adjuster reviewing your file six months later sees only two things: what the medical records say, and how long you waited before creating them.
Hour One: At the Scene
Call 911 even for a collision that looks minor. A police report creates a contemporaneous record of the vehicles, their positions, statements made at the scene, and any citations issued. Without one, a disputed claim becomes one person's word against another's, and the insurer for the other driver has no reason to accept your version.
Do not say that you are fine. Say instead that you are not sure yet and want to be evaluated. Some version of the phrase "I'm fine" appears in adjuster notes constantly and is used to argue that no injury existed at the time of the crash.
Do not apologize or speculate about what happened. In the United States, apologies at crash scenes are routinely treated as admissions of fault. Be courteous without accepting blame, and avoid guessing at speeds, distances, or what the other driver was doing.
Photograph far more than you think you need. Capture both vehicles from four angles, all license plates, the full intersection or stretch of roadway, skid marks, debris fields, traffic signals and signs, weather and lighting conditions, and any visible injuries. Photograph the other driver's insurance card and license rather than copying the numbers by hand, which introduces transcription errors.
Collect witness contact information before anyone leaves. Witnesses become unreachable within days, and a neutral third party who saw the collision is frequently the difference between a disputed liability case and a clear one. A name and a phone number is enough.
If it is safe to do so, look for cameras. Traffic cameras, business security cameras, doorbell cameras, and dashcams in nearby vehicles all record over their footage on short cycles, sometimes as little as 72 hours.
Hours 1 to 24: Medical Care and Documentation
Go to an emergency room, an urgent care clinic, or your primary physician the same day when possible. Tell the provider about every symptom, including ones that seem trivial or unrelated. Headaches, dizziness, nausea, numbness, tingling, ringing in the ears, blurred vision, difficulty concentrating, irritability, and sleep disruption all matter. If a symptom is not recorded in the chart, it effectively did not happen as far as an insurer is concerned.
Follow the discharge instructions exactly. If you are told to follow up with a specialist within five days, do it within five days. Treatment gaps are the single most commonly cited justification for reduced settlement offers, and a gap created by a scheduling problem looks identical in the file to a gap created by an absence of injury.
Keep every piece of paper you receive. Discharge summaries, prescriptions, imaging orders, work restriction notes, and receipts for anything you pay out of pocket all become part of the claim.
Start a simple daily log. A few sentences each day about your pain level, what you could not do, sleep quality, and missed activities creates a contemporaneous record that is far more persuasive than a recollection assembled a year later.
Hours 12 to 48: Notifications
Report the crash to your own insurance company. Nearly every policy requires prompt notice, and failing to provide it can jeopardize your own coverage, including the uninsured motorist benefits you may end up needing. Reporting the accident is not the same as admitting fault or filing a claim against yourself.
Check your policy for Personal Injury Protection or MedPay coverage. In no-fault states including Florida, Michigan, New York, New Jersey, Pennsylvania, and Minnesota, your own PIP coverage pays medical bills first regardless of fault, and several of those states impose a short deadline for seeking initial treatment. In Florida that window is measured in days rather than months, and missing it can forfeit the benefit entirely.
Notify your employer in writing if you are missing work. Wage loss claims require documentation of your rate of pay, your normal schedule, and the specific hours missed. A verbal conversation with a supervisor will not satisfy an adjuster.
Preserve your vehicle. Do not repair it, sell it, or authorize a salvage yard to dispose of it until it has been photographed and, in a serious case, inspected. Vehicle damage is evidence of impact force, and it becomes central when an adjuster argues the collision was too minor to have caused injury.
What Not to Say to an Insurance Adjuster
Do not give a recorded statement to the other driver's insurer. You are under no legal obligation to do so. Adjusters are trained to ask questions that produce useful answers, including open-ended prompts about whether you were distracted and cheerful check-ins about whether you are feeling better today. You can decline politely and provide the basic facts of the collision in writing instead.
Do not accept a quick settlement. Early offers arrive before anyone knows whether you will need physical therapy, injections, or surgery. Signing a release closes the claim permanently.
Do not post about the accident on social media. Insurers review public profiles. A photograph of you hiking, a comment that you feel better, or a check-in at a gym will surface at exactly the wrong moment.
Do not sign a broad medical authorization from the other driver's insurer. These forms frequently grant access to your entire medical history, which is then searched for any prior complaint involving the same body part.
Do not exaggerate. Overstating symptoms is far more damaging than understating them, because a single provable exaggeration undermines everything else in your file.
Special Situations
If it was a hit and run, report it to police immediately. Your uninsured motorist coverage generally applies, but most policies impose a short reporting deadline for hit-and-run claims, and a delay can void the benefit. An insurance claims attorney can step in quickly if the carrier disputes the claim.
If a commercial vehicle or truck was involved, evidence preservation matters enormously. Electronic logging device data, dashcam footage, driver qualification files, and maintenance records can be overwritten or destroyed on routine retention schedules. A preservation letter sent quickly can prevent that.
If a government vehicle was involved or a road defect contributed, claims against cities, counties, and state agencies often require formal written notice within 60 to 180 days, far shorter than the ordinary statute of limitations.
If you were partly at fault, do not assume you have no case. Most states allow recovery reduced by your percentage of fault. Only Alabama, Maryland, North Carolina, Virginia, and the District of Columbia bar recovery entirely for any contributory fault.
If you were a passenger, you are almost never at fault, and you may have claims against more than one driver's policy.
When to Call an Attorney
Not every minor collision requires legal representation. Consider making a call within the first few days if any of the following apply: anyone was transported by ambulance, liability is disputed, the other driver was uninsured or underinsured, a commercial vehicle was involved, you are missing work, your injuries required imaging or a specialist referral, or an adjuster has already contacted you with an offer.
Not sure if your case needs a lawyer yet? Most car accident attorneys offer a free consultation and handle injury cases on contingency, meaning there's no fee unless they recover money for you. A short call in the first few days often clarifies whether you can handle the claim yourself.
Frequently Asked Questions
How long do I have to see a doctor after a crash?
Legally it varies by state, but practically you should be seen within 24 to 72 hours. Some no-fault states impose statutory deadlines as short as 14 days for Personal Injury Protection eligibility.
Do I have to call the police for a minor accident?
Many states require a report when there is any injury or when property damage exceeds a dollar threshold. Even when a report is not required, having one protects you if the other driver later changes their account.
What if I did not feel hurt at the scene but do now?
This is extremely common and medically well documented. Seek care immediately and tell the provider clearly that the symptoms began after the collision.
Can I still recover if I was not wearing a seatbelt?
It depends on the state. Some allow evidence of nonuse to reduce damages under a seatbelt defense, while others prohibit it entirely.
Should I use my own health insurance for treatment?
Usually yes, because it keeps bills from going to collections. Understand that your health insurer may assert a lien against any eventual settlement.
What if the other driver has no insurance?
Your uninsured motorist coverage applies. Report the crash to your own insurer promptly to preserve that claim.
Do I have to talk to the other driver's insurance company at all?
You must generally cooperate with your own insurer under your policy. You have no such obligation to the other driver's insurer beyond providing basic contact and vehicle information.
How do I get a copy of the police report?
Most agencies make reports available within three to ten days, through an online portal, by mail, or at the records division. The responding officer usually provides a report or incident number at the scene.
What if the damage to my car looks minor?
Modern bumpers are designed to absorb impact without visible deformation, and occupants can still be injured. Photograph the damage anyway and describe the force of the impact to your doctor.
Should I get my own repair estimate?
Yes. You are generally not required to use the insurer's preferred shop, and an independent estimate gives you a basis for disputing a low property damage valuation.
