A hit and run is leaving the scene of a collision without stopping to identify yourself, provide your details and give whatever help is needed. It is an offence in every state, and in most of them it is an offence whether or not the crash was your fault.
That last part is what catches people. The duty to stop does not depend on blame. A driver who was hit by somebody else and drove off has still broken the law, and the fact that the other party caused it is no defence to leaving.
The seriousness depends almost entirely on what was damaged. Scraping a parked car is usually a misdemeanour. Leaving after someone was injured or killed is a felony in most states, and the sentences are severe.
What the Law Requires You to Do
The wording differs by state, but the duties are consistent. The Cornell Law School summary of hit and run statutes sets out the general shape, and in practice it comes down to five things.
- Stop immediately, at the scene or as close to it as is safe. Moving the vehicle out of a live lane is allowed and sensible. Driving home is not.
- Stay until the exchange is done. Leaving after a brief argument, or after the other driver says it is fine, still counts as leaving in some states.
- Identify yourself with your name, address, vehicle registration and insurance details, and show a licence if asked.
- Render reasonable assistance to anyone injured, which usually means calling emergency services and staying until they arrive rather than providing treatment yourself.
- Report it where the law requires, which is normally any crash involving injury, death, or damage above a state threshold, and nearly always where the other vehicle or property is unattended.
For an unattended vehicle or property, the usual rule is to make a reasonable effort to find the owner and, if you cannot, leave a written note with your name and contact details in a secure place and report it to the police.
Fault Has Nothing to Do With It
Two separate questions get confused here.
Who caused the collision is a civil question about compensation. Whether you stopped is a criminal question about your conduct afterwards. You can be entirely blameless for the crash and still be prosecuted for leaving it, and a conviction for leaving does not by itself prove you caused the crash either.
People leave for reasons that feel urgent at the time: no insurance, a suspended licence, having had a drink, being undocumented, panic, or simply thinking the damage looked minor. None of those is a defence, and all of them make the eventual outcome worse than staying would have.
When It Becomes a Felony
The dividing line is harm to a person.
- Property damage only. Usually a misdemeanour, with fines, points and possible licence suspension. Some states grade it by the dollar value of the damage.
- Injury. A felony in most states, or a misdemeanour that can be charged as a felony depending on severity.
- Serious bodily injury or death. A felony everywhere, commonly carrying years in prison, and in several states the sentence is increased specifically because the driver left.
- A prior conviction for the same offence raises the grade in many states.
There is a particular cruelty in the injury cases. Leaving often causes the harm that the sentence then reflects, because the delay in medical help is what turns a survivable injury into a fatal one.
The Penalties Beyond the Court
The sentence is only part of it.
- Licence suspension or revocation, which is frequently automatic and separate from the criminal case.
- Insurance. A conviction puts a driver in the highest risk band for years, and some policies exclude cover entirely for an intentional act such as leaving the scene.
- A criminal record, which a felony makes very difficult to work around in employment, licensing and immigration.
- Civil liability that runs alongside the prosecution, and in some states punitive damages that would not be available if the driver had stopped.
- Restitution ordered by the criminal court, which is separate from any civil settlement.
Situations People Do Not Realise Count
Hitting a Parked Car
The most common version by far. A note under the windscreen wiper is the minimum, and in many states it has to be reported as well. A note that blows away is still evidence you tried, which is why photographing it where you left it is worth the ten seconds.
Damage to Property Rather Than a Vehicle
A fence, a mailbox, a wall, a bollard, a parked trailer. The duty to find the owner or report it applies to property just as it does to cars in most states.
A Very Minor Impact
There is no minimum. A low speed bump in a car park with no visible damage can still be a crash that triggers the duty, and the other driver may report an injury days later.
Exchanging Only a Phone Number
Not enough in most states. The statute asks for name, address, vehicle details and insurance. A number scribbled on a receipt that turns out to be wrong looks like evasion afterwards.
Leaving to Get Help
Generally allowed where it is genuinely necessary, and expected to be followed by returning or reporting immediately. It is a narrow exception and it is judged on what you did next.
Hitting an Animal
A domestic animal is somebody’s property, and several states impose a specific duty to stop and report. Wildlife usually does not create the same duty, though a crash serious enough to damage vehicles often has to be reported anyway.
If You Were Hit and the Driver Left
- Do not chase them. Pursuit turns one incident into two, and a partial plate from a safe position is worth more than a dangerous chase.
- Call the police immediately and insist on a report number. Many insurance policies require a police report for a hit and run claim, sometimes within 24 hours.
- Write down everything you remember now: plate characters, make, model, colour, damage, direction of travel, anything about the driver. Memory for this degrades within the hour.
- Photograph your vehicle before it is moved, including the paint transfer, which is physical evidence that can be matched to the other car.
- Find witnesses and get phone numbers. In a car park, the car next to you may have a dashcam running.
- Look for cameras. Shops, car parks, traffic cameras and residential doorbells. Ask the same day, because most systems overwrite within days.
- Get checked medically even if you feel fine, and tell your insurer promptly whether or not you intend to claim.
Who Pays If the Driver Is Never Found
This is where the insurance side matters, and most people do not know what their own policy does.
Uninsured Motorist Cover
The main route. In most states a hit and run driver counts as an uninsured driver, so uninsured motorist bodily injury cover responds to your injuries. Whether it covers the damage to the car depends on the state and the policy, and some require physical contact between the vehicles.
Collision Cover
Pays to repair your car whoever was at fault, subject to the deductible. Where the other driver is never identified, that deductible usually stays with you.
Medical Payments or Personal Injury Protection
Pays medical costs regardless of fault, up to the limit, and is the quickest money available because it does not wait for anyone to be identified.
The practical point: check whether you carry uninsured motorist cover before you need it. It is optional in many states and it is the single most useful cover a driver can hold.
How Drivers Get Identified
More often than people expect, and rarely through dramatic detective work.
- Paint transfer and debris. A broken mirror housing or a piece of trim carries a part number that narrows the vehicle to a model and year.
- Body shops. Several states require repairers to report damage consistent with a collision where no claim exists.
- Cameras. Doorbell cameras have changed these cases completely in residential streets.
- Witnesses with partial plates. Three characters and a colour is often enough to produce a short list.
- The driver reporting it themselves a day later, having thought about it, which is common and is treated far more leniently than being traced.
The Civil Claim Runs Separately
A prosecution punishes. It does not compensate you, beyond any restitution the court orders.
The civil claim for your injuries and your vehicle is a separate matter with a separate deadline, and it can succeed where a prosecution never happens. It also uses a lower standard of proof, so a driver who is identified but not charged can still be held liable.
Where the driver is never found, the civil claim becomes a claim against your own insurer under uninsured motorist cover, which is a negotiation like any other and not simply a form to fill in.
The Deadlines That Matter
Three separate clocks start at the moment of the crash, and they have nothing to do with one another.
Reporting to the Police
The shortest. Many states require a report within 24 hours, or within a few days where the crash is reportable at all. Miss it and you may lose the police report that your insurer then asks for.
Telling Your Insurer
Policies require prompt notice, and hit and run claims frequently carry a specific and short window, sometimes 24 hours, precisely because the insurer wants the incident investigated while evidence exists. A late notice is a reason to decline the claim.
The Civil Claim
The longest, commonly two or three years for injury. It feels distant on the day of the crash, which is why people let the first two deadlines slip while thinking they have plenty of time.
If a public vehicle was involved, a bus or a council truck, add a notice of claim deadline that can be as short as 60 days.
What the Evidence Looks Like Afterwards
These cases are won on physical detail rather than on testimony, because the person who could contradict you has gone.
Paint transfer is the strongest single item. When two vehicles touch, each leaves material on the other, and the colour and layer structure can be matched to a manufacturer and a paint code. Do not wash the car or have it repaired before it has been photographed and, where the case is serious, examined.
Broken parts matter for the same reason. A mirror cap, a fragment of indicator lens or a piece of bumper trim left on the road usually carries a moulded part number, and that number points to a model range and often a production period.
Camera footage is the most perishable. Domestic systems commonly keep between three and fourteen days, and shops often less. Asking on day one is a different exercise from asking on day ten, so knock on the doors nearby before the police get round to it.
Frequently Asked Questions
What is a hit and run?
Leaving the scene of a collision without stopping to identify yourself, exchange details and provide any assistance needed. It applies to crashes with other vehicles, with parked cars and with property.
Is a hit and run a felony?
It depends on the harm. Property damage only is usually a misdemeanour. Leaving after an injury is a felony in most states, and leaving after a serious injury or death is a felony everywhere.
Does it count if the crash was not my fault?
Yes. The duty to stop does not depend on who caused the collision. Being blameless for the crash is no defence to leaving it.
What if I hit a parked car and nobody is around?
Make a reasonable effort to find the owner, and if you cannot, leave a note with your name and contact details in a secure place. Most states also require you to report it to the police.
What should I do if someone hits me and drives off?
Do not chase them. Call the police and get a report number, write down the plate and vehicle description immediately, photograph the damage including any paint transfer, find witnesses, and check for nearby cameras the same day.
Who pays if the other driver is never found?
Usually your own insurer. Uninsured motorist cover treats a hit and run driver as uninsured and responds to injuries. Collision cover pays for the vehicle subject to your deductible, and medical payments or personal injury protection pays treatment costs regardless of fault.
Does my insurance go up after a hit and run I did not cause?
It can, depending on the state and the insurer, because the claim is paid without anyone to recover from. Several states restrict increases where the policyholder was not at fault.
How long do the police have to charge someone?
It varies by state and by whether the offence is a misdemeanour or a felony, commonly one to three years for a misdemeanour and longer for a felony. Some states run the clock from when the driver is identified.
Should I go back if I left the scene?
Reporting it yourself promptly is treated far more leniently than being traced, and it is the single best thing a driver in that position can do. Speak to a lawyer first if you can, and do not repair the vehicle in the meantime.
Can I still claim compensation if nobody is prosecuted?
Yes. The civil claim is separate, uses a lower standard of proof and has its own deadline. Where the driver is never found, that claim is made under your own uninsured motorist cover.
The practical summary is short. Stop, whatever happened and whoever caused it. If you were the one left behind, call the police the same day and check whether your policy carries uninsured motorist cover, because that is what decides who pays.
