You can leave an accident scene after exchanging information only when four things are all true at once: no one is injured or complaining of pain, the property damage looks minor, your vehicle is drivable and not blocking traffic, and no law enforcement officer has told you to stay. Miss any one of those, and driving away can turn a fender bender into a hit-and-run charge, even though you did the paperwork part correctly.
What Counts as a Complete Information Exchange
Every state requires drivers in a collision to stop and share identifying details with the other party. At a minimum, that means your full name, current address, and driver’s license number, plus your vehicle registration number and proof of insurance including the insurer’s name and policy number. The other driver owes you exactly the same.
Write it down or photograph it. A verbal exchange with nothing recorded is worth almost nothing weeks later if the other driver disputes what was said, or worse, claims you never stopped at all. Snapping a photo of their license, insurance card, and license plate takes seconds and gives you a dated record that you were there.
When You Can Actually Drive Off
Once the exchange is done, run through the four conditions honestly. No injuries and no complaints of pain, even mild ones. Damage that looks cosmetic. A car that starts, steers, and isn’t sitting in a live lane. No officer on scene telling you to wait. When those all hold, your on-scene duties are finished and you can go.
The tricky one is damage. A cracked bumper cover can hide thousands of dollars in structural repair underneath, and “minor” is easier to misjudge than most drivers realize. When in doubt, call the non-emergency police line and ask whether an officer should come out. If dispatch says no, that itself becomes useful evidence that the crash was treated as minor.
When You Have to Stay Until Police Arrive
Four situations override the exchange-and-leave option. In any of them, driving away is a criminal offense even if you handed over every piece of required information:
- Anyone is hurt or killed. A complaint of neck pain, dizziness, or a headache counts. You cannot diagnose injuries at the roadside, and any reported symptom triggers the duty to stay.
- Damage exceeds your state’s reporting threshold. Most states set this somewhere between $500 and $2,500, with outliers as low as $50 and as high as $3,000. If damage looks anywhere near the line, treat it as over.
- Your vehicle is disabled or blocking traffic. A stopped car in a travel lane creates a serious risk of a secondary crash, and police need to manage the scene.
- An officer tells you to wait. Once law enforcement is involved, you stay until you’re cleared to go, no matter how minor the accident looks.
If someone is visibly hurt or says they are, staying is only part of it. You also have to take reasonable steps to get them medical help, which in practice means calling 911. You are not expected to perform first aid you haven’t been trained in, and you should not move someone with a possible spinal injury. Calling for professional help and staying with the person until it arrives satisfies the duty in almost every case.
Staying Doesn’t Mean Sitting in the Road
A growing number of states now require drivers to move drivable vehicles out of travel lanes after a property-damage-only crash. Washington’s statute is typical: drivers must move off main lanes, shoulders, and medians to the nearest safe location, such as an exit ramp shoulder or a cross street. These “move it” laws exist because a stopped car on a highway is itself a hazard.
Moving your car does not change who was at fault. Before you pull forward, take a few quick photos of both vehicles in their original positions so the physical evidence is preserved. Then finish the exchange from a safer spot.
Parked Cars, Mailboxes, and Other Unattended Property
The rules shift when there is no other driver to exchange information with. If you hit a parked car, clip a mailbox, or knock over a fence, you cannot just leave because nobody saw it. Every state requires a reasonable effort to find the owner. If you cannot, you have to leave a written note in a visible spot with your name, address, phone number, and a short description of what happened, and notify local police.
A surprising number of hit-and-run charges start here. Drivers assume that a low-speed bump in a parking lot doesn’t count or that a scraped fender won’t be noticed. Lots often have cameras, and witnesses are more common than people expect. A note and a call to police take five minutes and eliminate the criminal exposure.
What You Still Owe After You Drive Home
Leaving the scene lawfully doesn’t close the file. Most states require drivers to file a written accident report with a state agency, often the DMV or department of public safety, when a crash involves injury, death, or damage above a set threshold. Thresholds run from as low as $50 in Tennessee to $3,000 in Hawaii and Vermont, with most states landing at $500 or $1,000.
Deadlines vary just as widely. Some states demand an immediate report; others give up to 30 days, and a large number use a 10-day window. This report is separate from any police report filed at the scene, and you have to submit it regardless of fault or whether police responded. Missing the deadline can trigger a license suspension.
Your insurance policy almost certainly also requires you to report accidents “as soon as practicable.” That is a contractual duty, independent of state law. Delayed reporting gives your insurer grounds to deny the claim or refuse to defend you if the other driver sues, which could leave you personally responsible for the other party’s injuries and repairs. A same-day call to your insurer, even for a crash that seems trivial, protects your coverage.
Before You Pull Away
A few minutes of documentation at the scene will matter more than you expect if the claim is disputed later. Photograph both vehicles from several angles, the wider scene showing lane markings and traffic signals, close-ups of damage and paint transfer, and both license plates. Note anything about the road: skid marks, debris, weather, construction. Look around for businesses or traffic cameras that might have caught the collision, so you or your insurer can request footage before it’s overwritten. If anyone saw what happened, get their name and phone number; witness memory fades fast.
Say as little as possible about how it happened. You are required to share identifying and insurance details. You are not required to discuss fault, and doing so almost always works against you. A reflexive “I’m sorry” or “I didn’t see you” can be treated as an admission by the other driver’s insurer or attorney. Stick to the required facts. If the other driver wants to hash out the details, “I think we should let the insurance companies sort that out” is a safe response.
What Happens If You Leave When You Shouldn’t Have
Driving away without meeting your legal duties is a hit-and-run, and the penalties scale with the severity of the crash. For property-damage-only cases, it is typically charged as a misdemeanor, with fines up to $1,000, jail time up to six months to a year, and a license suspension depending on the state. When someone is injured or killed, many states elevate the offense to a felony carrying substantially longer prison sentences, larger fines, and in some places mandatory license revocation.
These are not paper penalties. Prosecutors pursue hit-and-run cases aggressively because juries view fleeing as a separate wrong on top of whatever caused the crash. That same impression follows you into any civil lawsuit, where a jury weighing damages will hear that you drove away from someone you injured. If the four conditions at the top of this page aren’t all clearly met, the safer move is always to stay.
