What NOT to Do in the First 24 Hours After an Accident

The first few hours after a crash can impact your health, your claim, and your legal options.

A car accident can change everything in seconds. The stress, the confusion, the adrenaline — it all happens at once. And in the middle of that chaos, many people make decisions that can affect their legal case and their ability to seek fair compensation without even realizing it.

It’s not your fault. Most of us are never taught what to do — and what NOT to do — after an accident. That’s why we put together this guide: so you have the information before you ever need it.

Note: This guide provides general information. If you are injured, seek medical attention right away. For guidance about your specific situation, consult with an attorney licensed in your state.

1. Do NOT admit fault at the scene — even if you think you made a mistake

It’s natural to want to apologize after a crash. Saying “I’m sorry” or “I didn’t see you” may feel like the right thing to do in the moment. But anything that sounds like an admission of fault can be used against you later — by the insurance company or by the other party’s attorney.

What NOT to say:

• “It was my fault.”
• “I wasn’t paying attention.”
• “I’m sorry, I didn’t see you.”
• “I’m fine.” (when you don’t know that yet)

What you CAN say:

• “Are you OK?”
• “Let’s call the police.”
• “I’d rather not discuss the details until the authorities arrive.”

The reality is that you do not have all the information at the scene. There may be factors you do not know about yet: a blocked traffic sign, a mechanical issue with the other vehicle, or road conditions that contributed to the crash. Saying less at the scene can help protect you.

Important: This also applies when speaking with the police. Be brief, describe what happened without assuming fault, and let the investigation determine responsibility.

2. NEVER accept a quick settlement in the first 24 hours

The other driver’s insurance company or its insurance adjusters may contact you very soon after the accident — sometimes within hours. They may sound friendly, understanding, and even offer you a check to “resolve this quickly.”

Do not accept it.

That first offer is often much lower than what your case may actually be worth. And there is a reason they move quickly: they want you to sign before you know the full extent of your injuries, before you speak with an attorney, and before you understand your rights, which can weaken your insurance claim.

Why is it so risky to accept quickly?

• Many injuries do not appear right away. Whiplash, soft tissue injuries, traumatic brain injuries, and internal bleeding can take hours or days to show symptoms. The adrenaline of the moment can hide the pain.
• If you sign a settlement, you generally give up your right to seek more compensation later — even if you later discover that your injuries are worse than you thought.
• The insurance company may have interests that are different from yours and may try to resolve the claim for as little as possible.

What to do instead:

• Do not give a recorded statement to the other driver’s insurance company without speaking with an attorney.
• If they pressure you, you can say: “I need time to evaluate my situation before making any decisions.”
• Seek legal guidance. A free consultation can help you better understand the potential value of your case.

Do not ignore your own insurance company, but be careful about what you say

After an accident, you may need to report the crash to your own insurance company. Do not ignore that obligation, because your policy may require you to notify the company within a certain timeframe.

When you speak with your insurer, share only the basic facts with the adjuster: when the accident happened, where it happened, which vehicles were involved, and whether there are any known injuries. Avoid speculating about who was at fault, minimizing your symptoms, or giving a recorded statement without understanding your rights. Before discussing coverage or payments, also check whether your policy includes PIP.

If you are not sure what to say, or if the insurance company asks you to sign documents, accept an offer, or give a formal statement, consider speaking with an attorney first.

3. Document the scene BEFORE anything moves

In the minutes after an accident, the scene is your best evidence. But that evidence can disappear quickly: cars get moved, police clear traffic, witnesses leave. If you do not document what happened in that moment, it can be much harder to reconstruct it later.

What to document with your phone:

• Take clear photos of the vehicles from all angles, including the license plate, so the images show any vehicle damage clearly.
• Photos of the cars’ positions on the road before they are moved
• Skid marks, debris, broken glass
• Traffic signs, traffic lights, and road conditions
• Your visible injuries, such as bruises, cuts, or swelling
• Weather and lighting conditions

What else to do:

• Write down the names and phone numbers of witnesses. If someone saw what happened, their testimony may be important.
• Exchange information and contact details with the other driver involved.
• Ask for the police report or write down the report number, and keep a copy for your records. If police come to the scene, they may prepare a report.
• Save the other driver’s information: name, phone number, driver’s license number, insurance information, and the make and model of the car.

Keep a detailed written record of the incident while the details are still fresh.

In addition to photos and information, everything you collect may help with insurance and any next steps after the accident.

Evidence many people forget:

• Security cameras from nearby businesses, traffic cameras, if there are any nearby, and even doorbell cameras from nearby homes may have recorded the crash. This footage is often deleted within days or weeks, so it is important to identify it quickly.
• Your phone may have GPS and app data that can help establish your location and speed at the time of the accident.
• Some modern vehicles have systems that record information about speed, braking, and steering before impact. This data may be erased when the car is repaired or declared a total loss.

4. When to call the police — and when it may be required

In many states, you must call the police or report an accident if someone was injured, if someone died, if the other driver fled the scene, or if the damage is significant. In the first 24 hours after a car accident, call the police and stay at the scene, since leaving can lead to hit-and-run consequences. If there are injuries or an immediate safety risk, call 911 right away.

The exact rules depend on the state. For example, in Texas, drivers must immediately notify the police if an accident causes injury, death, or damage to a vehicle that prevents it from being driven normally and safely. In California, in addition to any police report that may be required, you must file an SR-1 form with the DMV within 10 days if someone was injured or killed, or if there was more than $1,000 in property damage. Maryland requires reporting accidents with over $1,500 in damage. Indiana law mandates reporting accidents causing injury or damage over $1,000.

On the road, your priority is to get to a safe location outside the flow of traffic after a collision if you can do so without making the situation worse. Turn on your hazard lights and move vehicles out of traffic if possible.

Check the specific state law after an accident, because the state where the accident occurred determines the reporting requirements. Arizona is a fault state, so the at-fault driver is responsible for damages.

Do not move a seriously injured person if they have neck or back pain, unless there is an immediate danger.

Why is this important?

• A police report is an official record that records the facts of the accident. Without it, your case may become “your word against theirs.”
• In many states, failing to report an accident can have legal consequences.
• If there are injuries — even if you are not sure how serious they are — calling the police creates an immediate record.

When may reporting be required? Laws vary by state, but in general, you should report an accident if:

• Someone was injured, even if the injuries seem minor
• There was significant damage to the vehicles
• The other driver fled the scene, also known as a hit and run
• There was damage to public property, such as poles, signs, or guardrails

Tip: Even if you are not sure whether the accident is “serious enough” to call the police, make the call. The first 24 hours after a car are critical for safety and legal rights, so it is better to have a report you do not need than to need a report that does not exist.

5. Call an attorney before it is too late

The first 24 hours after an accident involve important decisions — and most people face them without legal guidance, even though organized action in that window helps protect both your safety and any insurance claim. That can give insurance companies an advantage, since they have adjusters and attorneys working from the beginning to protect their interests while many accident victims are left at a disadvantage.

Calling an attorney does not mean you are going to sue someone. It means you are going to understand your options before making decisions you cannot undo.

What can an attorney do for you in the first few hours?

• Guide you on what to say and what not to say to insurance companies, and help protect the documents and records needed for a claim, including lost wages if time away from work becomes part of the case
• Help you understand whether you may have a case
• Help make sure evidence is preserved
• Protect you from signing documents that may limit your rights
• Explain the process so you know what to expect
• Help you understand what compensation may be available and how to protect your rights

How much does it cost? Many personal injury attorneys work on a contingency fee basis, meaning they do not charge unless they recover compensation for you. An initial consultation is usually free.

Do not post anything on social media

This mistake deserves its own section. After an accident, it can be tempting to post a photo, a comment, or even a status update saying you are OK. But insurance companies may monitor social media, and anything you post can be used against you.

A simple “I’m OK, thank God” can be interpreted as evidence that your injuries are not serious. A photo of you smiling with your family can be used to argue that you are not suffering. Even checking in at a restaurant days after the accident can be presented as proof that your quality of life was not affected.

The rule is simple: Do not post anything about the accident, your injuries, the other driver, or your case on any social media platform until you speak with an attorney.

Seek medical attention — even if you feel fine

Adrenaline after an accident can hide serious symptoms. Some injuries from a car crash are not felt right away and may appear hours or days after the crash.

Injuries that may take time to appear include:

• Whiplash
• Soft tissue injuries
• Traumatic brain injury and concussions
• Internal injuries
• Back and spine injuries

You should seek medical care within 24 hours after an accident, because prompt medical care can support recovery and create documentation that connects your symptoms to the accident. If you wait days or weeks, the insurance company may argue that your injuries were not caused by the crash.

Whiplash and concussions may appear 24 to 48 hours later, and serious symptoms require immediate medical attention or emergency medical assistance. Follow your doctor’s instructions and keep all medical records from all treatment and follow-up care, including diagnoses, prescriptions, bills, and treatment recommendations.
