What to Do in the First 24 Hours After a Car Accident

A car accident scrambles your thinking even when it’s minor. Your heart’s pounding, your car might be making a noise it’s never made before, and there’s a stranger standing in the road with you who you need to talk to calmly. Having a mental checklist ready – before you ever need it – makes those first confusing minutes a lot more manageable. Here’s what to do, roughly in order, and why each step matters.

Checking on safety before anything else

Before you worry about paperwork, insurance, or whose fault anything was, deal with safety. This part isn’t optional and it comes first every time.

• Check yourself first. Adrenaline is a good painkiller, which means you can be hurt and not know it yet. Take a breath and do a quick mental scan: can you move your hands and feet, turn your head, take a full breath without sharp pain? If anything feels wrong, stay still and say so when help arrives.
• Check on your passengers and then the other driver. Ask directly: “Are you hurt? Can you move?” Don’t assume someone’s fine just because they’re standing and talking – shock hides a lot.
• Get out of traffic if you can. If the vehicles are drivable and nobody has a neck or back injury, move them to the shoulder or a nearby parking lot. A stopped car in a live lane is how minor accidents turn into pile-ups. If someone is seriously hurt or the cars won’t move, leave them where they are and focus on getting help instead.
• Turn on hazard lights and set up warning if you have it. Road flares or reflective triangles behind the vehicles give other drivers time to react, especially at night or on a highway.
• Call 911 if there’s any injury, significant damage, or blocked traffic. Even for a fender-bender, many states want a police report once damage passes a certain threshold, and an officer on scene can help manage traffic and emotions. When in doubt, call. It costs you a bit of time; not calling can cost you a lot more later if questions come up about what happened.

If anyone mentions neck pain, dizziness, numbness, or just says they feel “off,” let the paramedics make that call rather than waving them away. Some injuries, like concussions or whiplash, don’t announce themselves right away.

Information to exchange and photograph at the scene

Once everyone’s safe and out of the roadway, it’s time to gather information. Think of yourself as collecting evidence for a report you’ll need to fill out later – because you will.

What to exchange with the other driver

• Full name and phone number
• Driver’s license number
• License plate number and the car’s make, model, and color
• Insurance company name and policy number (take a photo of their insurance card rather than copying it by hand – it’s faster and less error-prone)
• Location of the accident, including street names, mile markers, or a nearby landmark if you’re not sure of the exact address

If there’s a passenger in the other vehicle, or witnesses who stopped, grab their names and phone numbers too. A witness who saw the sequence of events can be genuinely helpful later, and people who linger at an accident scene often leave before anyone thinks to ask for their contact information.

Keep the conversation factual and polite. You don’t need to discuss who did what or apologize for anything – just swap information like you’re exchanging business cards. Emotions run high after a crash, and it’s easy to say something you don’t mean or that doesn’t actually reflect what happened. Stick to names, numbers, and logistics.

What to photograph

Your phone’s camera is one of the most useful tools you have in these first 24 hours. Take more photos than you think you need – you can’t go back and take more later once cars have been moved or repaired.

• Wide shots of the whole scene showing both vehicles, their position relative to the road, lane markings, traffic signs, and signals.
• Close-ups of all damage on both vehicles, from a few angles each.
• License plates on both cars, clearly readable.
• The road and surroundings – skid marks, debris, weather conditions, visibility, any relevant signage like stop signs or traffic lights.
• Interior damage if airbags deployed or anything inside was affected.
• Any visible injuries, if it feels appropriate to document them.

If a police officer responds, ask for the report number or the officer’s name and badge number before they leave. You’ll usually need the report number later to request a copy, and most departments take some time to process the report before it’s available.

When and how to contact your insurer

You don’t need to call your insurance company from the side of the road with your hands shaking, but you also shouldn’t wait too long. A good rule of thumb is to report the accident within a day, even if it seems minor or you’re not sure yet whether you’ll file a claim.

Here’s why prompt reporting matters: most policies require “timely notice” of an accident, and insurers use that information to start a claim file, which can include things like a claim number, a rental car authorization if you need one, and a timeline for getting your vehicle looked at. Waiting a week to report a scraped bumper might seem harmless, but if the other driver reports it first and the stories don’t line up on timing, it can create confusion that’s easy to avoid just by calling promptly.

How to make the call go smoothly

• Have your policy number ready, along with the other driver’s information and the photos you took.
• Stick to what you observed. Describe what happened factually – where you were, what direction you were going, what you saw and felt – without guessing about things you’re not sure of, like exact speeds or what the other driver was thinking.
• Ask what happens next. Every insurer handles claims a little differently, so ask directly: Will an adjuster call me? How do I get my car inspected? Do I need a rental car, and if so, how do I arrange one? Is there a list of repair shops I should know about?
• Write down who you talked to and when. A simple note with the date, time, and the claims representative’s name can save you a headache if you need to follow up later.

If the accident involved another driver and you’re not sure whether their insurance or yours will end up handling the repairs, don’t worry about sorting that out yourself in the moment. That’s part of what the claims process figures out. Your job right now is just to report accurately and promptly.

One more thing worth knowing: in many states, you’re also required to report certain accidents to the state’s motor vehicle agency, separate from your insurance report, especially if there were injuries or the damage was significant. Check your state DMV’s current requirements and deadlines, since they vary and sometimes come with a specific form.

What to expect in the days that follow

The first 24 hours are about safety and information-gathering. The days right after are about follow-through. Knowing roughly what’s coming can take some of the anxiety out of it.

• An adjuster will likely contact you. This could be from your own insurance company, the other driver’s, or both, depending on how the claim is being handled. They’ll ask you to walk through what happened, may request your photos, and will explain next steps for getting your vehicle assessed.
• Get your vehicle looked at even if the damage seems minor. Bumpers and panels can look fine while hiding structural or mechanical damage underneath. An inspection protects you from discovering a bigger problem weeks later.
• Keep every receipt related to the accident – towing, a rental car, even a rideshare you took to work while your car was in the shop. Ask your insurer early on what’s reimbursable so you’re not guessing after the fact.
• Watch for delayed symptoms. Soreness, headaches, or stiffness sometimes show up a day or two later. If that happens, see a doctor and let your insurer know, since medical documentation that’s close in time to the accident tends to be more straightforward to deal with than something reported weeks later.
• Expect some paperwork. Depending on your state and the situation, you may need to file an accident report with the DMV, fill out a claim form, or provide a recorded statement. None of this needs to happen all at once – ask your insurer for a clear list of what’s needed and by when.
• Give it time. Repairs, inspections, and claim decisions rarely happen overnight. If you haven’t heard anything in a few days, it’s completely reasonable to call your adjuster for an update rather than waiting and wondering.

None of this requires you to have all the answers in the moment. The goal for the first 24 hours is simple: make sure everyone is safe, gather clear information while it’s still available, and get the ball rolling with your insurer. Everything else – repairs, assessments, next steps – unfolds from there, usually in a more orderly way than those first shaky minutes might lead you to expect.
