First: get out of the way and check on people
| Order | Do this | Why it comes here |
|---|---|---|
| 1 | Hazard lights on | Costs a second and makes you visible to everyone approaching |
| 2 | If the car drives and nobody is badly hurt, get it out of the travel lane | Secondary crashes into stopped vehicles are the real danger |
| 3 | Move people away from the roadway, behind a barrier if there is one | Never stand between two vehicles or in a live lane |
| 4 | Check everyone, in both cars. Call for help if anyone may be hurt | Neck, back and head symptoms often present late |
| 5 | Decide about a police report | Requirements vary by state, and a record helps either way |
| 6 | Photograph everything before anything moves further | Debris, skid marks and positions disappear when the road clears |
| 7 | Exchange information, and get witness contacts before they leave | Witnesses are unfindable two minutes later |
| 8 | Notify your own insurer | Most policies require prompt notice of an incident |
The most dangerous part of a minor collision is often the minutes afterward, standing near live traffic. Secondary crashes into stopped vehicles and people on foot are a real and recurring pattern, and they injure people the original impact did not touch.
So the order is: hazard lights on immediately. If the vehicle is drivable and there are no serious injuries, move it out of the travel lane, onto the shoulder, into a lot, past the intersection, wherever is clear. There is a persistent belief that vehicles must be left exactly where they stopped to preserve the scene. On a highway that belief gets people killed, and this is what photographs are for. If the car will not move, get everyone out on the side away from traffic and behind a barrier if there is one, not standing between vehicles.
Then check on people, in your car and the other one. Call for emergency help if anyone is or might be injured, if anyone is unconscious, if a vehicle is on fire or leaking fuel, or if the roadway is blocked. Injury after a collision can present late, particularly neck, back and head symptoms, so uncertainty is a reason to be evaluated, not a reason to skip it. Do not move someone who is injured unless they are in immediate danger from traffic or fire.
If you carry reflective triangles or flares, this is what they are for. Set them back up the road far enough that a driver coming around a curve has time to react.
Whether to involve the police
This is the part where a national guide has to be careful, because it genuinely varies. Many states require a collision to be reported when someone is injured or killed, or when property damage appears to exceed a dollar threshold, and that threshold is set state by state. It differs enough between states that quoting a number here would mislead more people than it helped. Your state's DMV, state police or department of transportation publishes the actual rule, and it is worth knowing yours before you need it.
Setting the legal requirement aside, there are practical reasons a report helps. It creates a contemporaneous, third-party record of the vehicles, drivers, location, time and conditions. It removes the situation where a driver who was apologetic at the scene tells a completely different story to an insurer a week later. And it gives your own insurer something to work from beyond two conflicting accounts.
Be aware that in many places, officers will not respond to a minor collision with no injuries, particularly on private property such as a parking lot, and may direct you to file a report yourself online or at a station within a set time. That is normal and it is not a reason to skip the documentation below. If an officer does respond, ask how to obtain a copy of the report and what identifying number to use.
Documentation, in the order you will regret skipping
Take far more photographs than feel necessary. Storage is free and you cannot go back.
| Shot | Why it matters later |
|---|---|
| Wide shots from four directions, showing both vehicles in position | Establishes geometry, lane positions and final rest points |
| The wider scene: intersection, signals, signs, lane markings, skid marks, debris field | Context that no written description recovers, and it is gone once the road is cleared |
| Close shots of every damaged area on both vehicles | Scope of damage before anything is moved, driven or repaired |
| Both license plates, clearly readable | Identifies the vehicles independently of what anyone wrote down |
| The other driver's license and insurance card | Faster and far more accurate than copying by hand in the dark |
| Road surface, weather, lighting, anything obstructing a view | Conditions are frequently disputed and are trivially provable now |
| Any visible injury | Time-stamped record from the day it happened |
Get witnesses before they leave, which they will do within about two minutes. A name and a phone number is enough. An independent account from someone with nothing at stake carries weight that neither driver's account can, and there is no way to find that person afterward.
If you have a dash camera, protect the file at the scene. Most units have a lock button or an impact-triggered lock, and if yours has neither, take the card out once it is safe to do so, because continuous loop recording will overwrite it as you drive. The dash cam guide covers how the locking and card handling works.
Exchanging information, and what to say
What you need from the other driver is narrow: full name, phone number, insurance company and policy number, driver's license number, and the plate and make and model of the vehicle. Note whether the driver is the registered owner, because if not you also want the owner's name. Give the same in return.
What you do not need is their opinion about fault, and they do not need yours. This is worth stating plainly because it is where people create problems for themselves: what you say at the scene can matter later. Statements made at a collision get repeated to insurers, appear in reports and are recalled in claims. Reflexive apology is normal human behavior and it is routinely reported afterward as an admission.
The workable approach is to describe facts and decline to characterize them. You can say where you were, what direction you were traveling, what speed, what the signal was doing. You do not have to assign responsibility to anyone, including yourself, and you are not in a position to do so at the scene, because you do not yet know what the other vehicle was doing, what a camera recorded, or what a witness saw. Fault determination is a matter for the insurers, and where they disagree, for the legal process. This page is not legal advice, and if the collision involved injuries, a dispute over what happened, or a citation, talking to an attorney licensed in your state is the appropriate next step rather than reading further on the internet.
If the other driver leaves the scene, do not chase them. Get whatever you can of the plate, the vehicle description and the direction of travel, and report it. If the other driver has no insurance or refuses to provide information, that is a situation for the police and your own insurer.
Notifying your insurer, and the days after
Report the collision to your own insurer promptly even if you believe you were not at fault and even if you are unsure whether you will file a claim. Policies generally contain a duty to give prompt notice of an incident, and late notice is the kind of technicality that complicates a claim you eventually do need. Reporting an incident is not the same as filing a claim, and you can ask your insurer to explain the distinction as it applies to your policy.
Have ready: the date, time and location, the other driver's information, the photographs, the police report number if there is one, and a factual account of what happened. Ask directly about three things people forget to ask about, because the answers depend on your specific coverage: whether you have a rental or transportation allowance while the car is repaired, what your deductible is and whether it is waived if the other party's insurer accepts responsibility, and whether you may choose your own repair shop.
In the days afterward, keep a folder. Every estimate, every invoice, every claim number, the name of every adjuster and the date of every call. Get an independent repair estimate if the one you are offered seems low, since you are generally entitled to a proper repair rather than the cheapest available one. And watch your own body: symptoms that appear two days later are common, and being seen by a physician creates the medical record that makes those symptoms part of the claim rather than an unsupported assertion.
One last thing that sits outside the immediate mess. A repaired collision usually leaves a mark on the vehicle's history, and that shows up years later as a lower price when you sell, separately from whatever the repair cost. If the car took structural damage, it is worth running the numbers on what the vehicle will be worth at the point you planned to sell it, because the answer sometimes changes whether repairing it is the right call at all.
Questions people ask
Do I have to call the police for a minor fender bender?
It depends on your state and on the circumstances. Many states require a report when there is an injury or a fatality, or when apparent property damage exceeds a dollar threshold, and that threshold is set state by state and varies enough that no single number applies nationally. Your state DMV or state police site publishes yours. Separately from the legal requirement, a report is often useful because it creates a neutral, time-stamped record of who was there and what the conditions were. Be aware that officers frequently do not respond to minor, injury-free collisions and may direct you to file a report yourself within a set number of days.
Should I just settle it with the other driver and not involve insurance?
It is a common impulse and it carries risks worth understanding. Damage that looks cosmetic can hide structural or sensor damage that a shop finds later, so the amount agreed at the roadside is frequently far below the real repair cost. Injuries can appear days afterward. And a private agreement offers little protection if the other party later changes their account or files a claim anyway. Your policy also probably requires prompt notice of an incident, which is not the same as filing a claim. At minimum, document the scene fully and notify your own insurer of the incident, then decide about a claim once you know what the damage actually is.
Should I admit fault at the scene?
This guide does not give legal advice, and fault is not something you can accurately determine standing at the roadside minutes after an impact. What can be said plainly is that statements made at the scene get repeated later, to insurers and in reports, and that reflexive apology is routinely recalled as an admission. Sticking to facts is the practical approach: where you were, your direction, your speed, what the signal showed. Fault determination is what insurers do, using the physical evidence, the report and any recordings, and where they disagree it is resolved through the legal process. If there are injuries, a citation, or a real dispute, talk to an attorney licensed in your state.
What information do I need to exchange?
Full name and phone number, insurance company and policy number, driver's license number, and the license plate with the make and model of the vehicle. Ask whether the driver is the registered owner, and if not, get the owner's name too. Photographing the license and insurance card is faster and more accurate than transcribing it, especially at night. Also collect the names and numbers of any witnesses before they leave, because an independent account from someone with no stake in the outcome carries weight neither driver's account can, and they are unfindable afterward.
What if the other driver has no insurance or drives off?
Do not pursue a driver who leaves. Capture whatever you can of the plate, the vehicle description, the damage and the direction of travel, then report it to the police and to your own insurer. For both hit-and-run and uninsured drivers, whether you have coverage depends on your policy, so call your insurer and ask specifically what applies. Uninsured and underinsured motorist coverage exists precisely for this situation and its availability and terms vary by state and by policy. This is also the scenario where a dash cam earns its cost, so if you have one, protect the file before you drive anywhere.
