What Should You Do in the First 24 Hours After a Serious Car Accident in Illinois?
The first 24 hours after a serious crash are not about building the perfect personal injury case. They are about protecting your health, getting the facts right, and avoiding decisions based on information you do not have yet.
When someone calls me shortly after a collision, I do not expect that person to have everything figured out. They may be in pain. Their car may have been towed. They may be worried about work, their children, transportation, or whether the other driver even has insurance. They may also be getting calls from people asking for answers while they are still trying to understand what happened.
My advice is to focus on the things that actually matter first.
Medical documentation starts with an accurate history
Medical decisions belong to patients and licensed medical professionals independently of an insurance claim. Duran Law Offices does not direct testing or treatment. For the legal claim, records of care actually received may document symptoms, examination findings, and the chronology.
One thing I tell clients is not to minimize symptoms because they are trying to be tough. If your neck hurts, say it. If you are dizzy, say it. If your back started hurting several hours after the collision, be accurate about when it began.
The opposite is just as important: do not exaggerate. A medical history is most useful when it is accurate.
Imagine someone who has significant shoulder pain at the emergency room but is much more worried about a cut on his face. He talks almost entirely about the cut and barely mentions the shoulder. Two weeks later, the shoulder becomes the major problem. That does not necessarily mean the shoulder injury is unrelated to the crash, but now there is an obvious question about what was reported initially.
I would rather understand the real progression of symptoms than try to repair an inaccurate story months later.
Preserving basic facts after a serious crash
Immediately after a serious collision, people are understandably focused on getting home or getting to the hospital. Basic information can become scattered.
If it can be done safely, make sure you know where the vehicle was taken, obtain the other driver's and insurance information, keep photographs or videos already taken, and save any paperwork you receive from police, paramedics, the hospital, or the towing company.
If you know a dash camera, doorbell camera, business camera, or other video may have captured the collision, make a note of where it was. You do not need to conduct your own investigation from a hospital bed, but identifying a likely source early can matter because some systems do not retain footage indefinitely.
If the vehicle may contain important physical or electronic evidence, do not rush to authorize repairs, disposal, or destruction before the appropriate insurers and attorneys have had an opportunity to address inspection and preservation. The same practical rule applies to photographs and video already in your possession: keep the originals.
And do not turn the crash into social-media content. A post written while you are upset, medicated, or working from incomplete information can create an unnecessary factual dispute later.
Illinois law requires a driver involved in a crash resulting in personal injury or death to stop and remain at, or return to, the scene until the duties in 625 ILCS 5/11-403 are fulfilled, including providing specified identifying information and rendering reasonable assistance to an injured person when required. If no police officer is present, Illinois law also requires the driver to give prompt notice of an injury or death crash to the appropriate law-enforcement agency under 625 ILCS 5/11-407. Those are duties imposed on drivers; they should not be confused with a blanket reporting duty imposed on an injured passenger.
Dealing with early calls when you do not have every answer
One of the most important things to understand after a serious crash is how much you do not know yet.
You may not know the diagnosis. You may not know whether you will miss work. You may not know whether the pain will resolve in three days or require months of treatment. You may not know exactly how fast the other vehicle was moving.
That uncertainty is normal.
If an insurance adjuster calls and asks how you are doing, there is a meaningful difference between saying, “My back is sore and I am following up tomorrow,” and trying to give a definitive description of an injury that has not been diagnosed yet.
I want clients to tell the truth. I also do not want them guessing.
Write down practical information while it is fresh
You do not need to spend the night creating a litigation file. But a few simple notes can help later.
Where did the collision happen? Where were you coming from and going? Who was with you? Where were you treated? What symptoms did you notice that day? Were you given restrictions or follow-up instructions? Where was the vehicle towed?
Those are ordinary facts. Weeks later, when someone is juggling appointments and trying to return to work, even ordinary facts can become harder to reconstruct.
Do not make permanent decisions based on temporary information
The day after a serious collision is usually too early to know the medical future or the value of a claim. Be cautious about treating an early diagnosis, an early insurance conversation, or an early settlement proposal as the final word.
Suppose a person is discharged with a diagnosis of neck and back pain and assumes the injury will resolve. Two weeks later, persistent symptoms lead to imaging and specialist care. An evaluation based only on the first day's information would have been incomplete.
The point is not that every injury gets worse. Many do not. The point is that serious decisions should be made with enough information to make them intelligently.
What I want to know when someone calls me after a serious crash
I want to understand what happened, where the person was treated, what symptoms are being reported, whether follow-up care has been recommended, what the person has been told by insurers, and whether there is anything that needs immediate attention.
I am not expecting a polished case presentation. I am trying to identify the important questions early and keep avoidable confusion from becoming part of the case.
