The moments immediately after a car accident can be chaotic, confusing, and frightening. But what you do, or don’t do, in the first 24 hours can make or break your health, your insurance claim, and any future legal case.
Naperville sees thousands of crashes every year. Between 2016 and 2024, the city documented over 30,000 collisions, leading to nearly 5,000 injuries. Knowing exactly what steps to take can protect you long after the tow truck drives away.
This guide walks you through the first 24 hours after a Naperville car crash, minute by minute.

Now let’s break down exactly what to do.
The First 15 Minutes: At the Scene
1. Stop and Stay Safe
Illinois law requires you to stop at the scene of any accident involving injury, death, or property damage. Move to a safe area – a sidewalk, shoulder, or nearby parking lot – and turn on your hazard lights.
2. Call 911
Even for minor fender benders, call the police. In Naperville, a police officer will respond and file an official crash report. That report is essential for insurance and any legal claim. Tell the dispatcher about any injuries so paramedics are sent.
3. Check for Injuries – Yours and Others
Adrenaline can mask pain. Check yourself and passengers for cuts, bruises, or soreness. If anyone complains of neck or back pain, do not move them unless there is immediate danger (like fire).
4. Do NOT Admit Fault
Never say “I’m sorry” or “It was my fault.” Even a casual apology can be used against you later. Stick to factual statements with the police: “I was going straight through the green light when the other car turned left.”
0‑2 Hours: Gather Evidence Before It Disappears
5. Exchange Information
Get the other driver’s:
- Full name and contact info
- Driver’s license number
- License plate number
- Insurance company and policy number
- Vehicle make, model, and color
Take a photo of their license and insurance card if possible.
6. Document the Scene with Photos and Video
Use your phone to capture:
- All vehicles from multiple angles (damage, positions)
- License plates of all involved cars
- Road conditions, traffic signs, skid marks, debris
- Your injuries (scrapes, bruises, swelling)
- The overall scene (intersection, lighting, weather)
These photos are gold for insurance adjusters and attorneys.
7. Find Witnesses
Look for anyone who saw the crash, other drivers, pedestrians, and nearby store employees. Get their names and phone numbers. Independent witnesses are often the difference between a disputed claim and a clear‑cut case.
8. Call Naperville Police for the Report Number
Ask the responding officer for the crash report number. You will need it later to obtain the official document.
2‑12 Hours: Medical and Documentation
9. Seek Medical Attention – Immediately
Even if you feel fine, see a doctor. Symptoms like whiplash, concussion, or soft tissue injuries can take hours or days to appear. Go to an emergency room or urgent care – Edward Hospital in Naperville is a common choice.
Why this matters: Insurance companies will argue that delayed treatment means your injuries weren’t serious. A same‑day medical record directly links the crash to your pain.
10. Write Down Everything While It’s Fresh
In a notebook or phone note, record:
- The time, date, and exact location of the crash
- What you remember about the other driver’s actions (e.g., “ran a red light”)
- What you said and what they said
- Weather and lighting conditions
Memory fades fast. Your notes can help your attorney later.
11. Do NOT Post on Social Media
Do not post anything about the accident on Facebook, Instagram, TikTok, or X (Twitter). Do not post photos of your injuries or your car. Insurance investigators monitor social media and will twist anything you say. Set your accounts to private until your case is resolved.
12‑24 Hours: Insurance and Legal Steps
12. Notify Your Own Insurance Company
Illinois law requires you to report the accident to your insurer within a reasonable time (usually within 24‑48 hours). Provide only the basic facts: when, where, and who was involved. Do not speculate about fault or describe your injuries in detail.
13. Do NOT Give a Recorded Statement – To Anyone
The other driver’s insurance company may call you as early as the same day. They will sound friendly and say they just need “a quick statement.” Politely decline: “I’m not ready to give a statement. Please contact my attorney.”
You are never legally required to give a recorded statement before hiring a lawyer. Anything you say will be used to reduce or deny your claim.
14. Get Your Police Crash Report
Naperville police reports are typically available online or in person within 3‑5 business days. Request it early and review it for errors. Mistakes in the report (wrong direction, missing witness) can hurt your case.
15. Contact a Local Car Accident Attorney
Within the first 24 hours, speak with a Marker Law car accident lawyer in Naperville. Most car accident attorneys work on contingency – you pay nothing unless they win. An attorney can:
- Communicate with insurance companies for you
- Preserve evidence before it’s lost
- Calculate the full value of your claim (medical bills, lost wages, pain and suffering)
- File a protective lawsuit if the statute of limitations is approaching
Many people hesitate, thinking they can handle it alone. But insurance companies have teams of adjusters and lawyers. Going up against them without representation is a mistake.

Frequently Asked Questions
Q: Do I really need to see a doctor if I feel fine?
A: Yes. Many serious injuries, such as whiplash, concussions, and internal bleeding, have delayed symptoms. A same‑day visit creates a medical record linking your pain to the crash. Without it, insurers will argue your injury happened later.
Q: Can I just handle the claim through the other driver’s insurance?
A: You can try, but you will likely leave money on the table. Insurance adjusters are trained to pay as little as possible. They may ask for a recorded statement, downplay your injuries, or offer a quick lowball settlement. An attorney levels the playing field.
Q: How long do I have to file a lawsuit in Illinois?
A: Generally, 2 years from the accident date. There are exceptions for minors or for injuries that were not discovered right away. However, waiting too long can destroy evidence and witness memory. Consult an attorney as soon as possible.
Q: What if the other driver doesn’t have insurance?
A: If you have uninsured/underinsured motorist (UM/UIM) coverage, your own policy may pay. An attorney can help you navigate that claim and sue the driver personally if the driver has assets.
Q: How much does a car accident attorney cost?
A: Most personal injury attorneys work on a contingency fee basis, typically 33‑40% of what they recover for you. You pay nothing up front and nothing if you lose. This aligns the attorney’s interests with yours.
Final Takeaways – Your First 24 Hours Checklist Recap
- Call 911 and get a police report.
- Take photos and get witness info.
- Please see a doctor the same day; no exceptions.
- Do not post on social media.
- Do not give a recorded statement to any insurance company.

The steps you take on the first day after a crash will determine whether you receive full compensation or fight an uphill battle. Insurance companies are not on your side. They have teams of professionals whose job is to negotiate lower pay for you.
You do not have to navigate this alone. A free consultation costs nothing and could be the most important call you make after an accident.
