Do you have to call the police if someone hits your car? Yes, any time someone is injured, and yes when property damage crosses the reporting threshold your state has set. Beyond those legal triggers, calling is still usually the right move, because a police report is often the single most useful document you can hand your insurance company.
When the Law Requires You to Call
If anyone involved in the collision is hurt or killed, you must contact law enforcement. That rule holds in all 50 states with no exceptions, and it covers injuries that seem minor at the scene. If the other driver, a passenger, or a pedestrian says they feel any pain at all, treat that as your cue to call.
Property damage triggers a mandatory report too, but the dollar threshold varies widely by state. Some states require a report for any visible damage; others set the bar at $2,500 or $3,000. Body-shop estimates routinely come in higher than people expect, so a dent that looks like a couple hundred dollars of damage can easily cross a reporting threshold once a mechanic actually inspects it. When you’re unsure, call. No one has ever been penalized for filing a report they didn’t technically need.
Collisions involving government vehicles, or damage to public property like guardrails, traffic signals, or utility poles, almost always require a report regardless of cost. The same is generally true when a commercial vehicle is involved.
If Your Car Was Parked
People often ask this question after walking out to find a dent, a cracked bumper, or worse. If the other driver left a note with contact and insurance information, you’re in a better spot than most, but still file a police report. The report creates an official record that protects you if the information on the note turns out to be fake or if the other driver’s insurer disputes the claim.
No note and no driver in sight means you’re dealing with a hit-and-run. Call the police. A report is almost certainly required by your state’s hit-and-run statute, and your insurance company will need one before processing the claim. Check nearby businesses for security cameras and ask anyone in the area whether they saw anything. Even a partial plate number or a vehicle description helps.
A driver who hits a parked car has a legal duty in every state to make a reasonable effort to find the owner. When the owner can’t be found, the driver must leave a written note with name, contact information, and insurance details, and in most jurisdictions must also notify police. Driving away without doing either is a hit-and-run, even when the damage is minor.
Why Calling Helps Even When It Isn’t Required
A police report is an independent, third-party account of what happened. It typically includes the date, time, and location of the crash, road and weather conditions, statements from both drivers, a diagram of how the collision occurred, and contact information for witnesses. Insurance adjusters rely on these reports when deciding fault, because the information was gathered at the scene by someone with no stake in the outcome.
Without a report, fault comes down to your word against the other driver’s. That’s a problem when the other driver changes their story, which happens more often than you’d expect. Someone who admitted fault at the scene can deny everything a week later after talking to their own insurer. A police report pins the details down before memories shift.
The report also speeds up the claims process. An adjuster who has a report number can pull the document directly and start working the claim, instead of chasing documentation from both parties.
Hit-and-Run and Uninsured Motorist Claims
If the driver who hit you fled, a police report isn’t just helpful; it’s practically required. Most policies won’t pay a hit-and-run claim under uninsured motorist coverage unless you reported the incident to police. From the insurer’s perspective, without a report there’s no independent verification that a hit-and-run actually happened rather than, say, the insured backing into a pole and inventing another vehicle.
File as soon as possible after discovering the damage. The longer you wait, the harder it becomes to argue the claim is legitimate.
What to Do at the Scene
Whether or not police respond, gather thorough information before you leave. From the other driver, get their full name, address, and phone number; their insurance company and policy number; their driver’s license number and license plate; and the make, model, year, and color of their vehicle.
Photograph the damage to both vehicles from several angles, and photograph the wider scene as well: road conditions, traffic signs, skid marks, and the positions of the cars before anything is moved. If there are witnesses, ask for their names and phone numbers. Adjusters value witness statements because they break the tie when two drivers tell different stories.
Be polite, but don’t apologize or say “it was my fault.” That kind of statement can resurface later in a claim dispute or a lawsuit, often stripped of context.
Filing a Report If Police Didn’t Come
Police don’t always respond to minor property-damage crashes, especially when nobody is hurt and the cars are drivable. When that happens, you can usually file the report yourself. Most state motor vehicle agencies accept a self-reported form, sometimes called a driver’s crash report or collision report, and the form is typically available for download on the state DMV or department of transportation website.
Deadlines vary. Most fall in the range of five to ten days after the accident. Miss the deadline and you can face administrative penalties, and in some states, failing to file a required accident report can lead to license suspension until you comply.
You can also walk into the local police station in the jurisdiction where the crash happened and ask to file a report there. Officers may not always take one for a minor property-damage accident from several days ago, but they’re more likely to help if you explain that your insurer requires it or that the damage turned out to be worse than it first looked.
If Injuries Show Up Later
Adrenaline masks pain. Whiplash, soft-tissue injuries, and concussions commonly appear hours or even days after a collision. If you declined medical attention at the scene and symptoms emerge later, see a doctor immediately and make sure the medical records explicitly tie the injury to the accident.
Notify your insurance company about the new symptoms as soon as they appear. Many policies set short windows for reporting injuries, and delays give insurers an easy reason to question whether the injury is truly accident-related. If you didn’t file a police report at the time, this is a good reason to file one now. A late report combined with a delayed injury claim can raise red flags with adjusters, so document everything as soon as you can.
Penalties for Leaving or Failing to Report
Consequences depend on how serious the collision was and whether you left the scene.
Leaving the scene of a crash that caused only property damage is typically a misdemeanor. Penalties generally include fines, points on your license, and possible short jail sentences. When someone is hurt or killed, fleeing the scene becomes a felony in virtually every state. Prison sentences can run from one to ten years or more, and your license will be revoked, often for years.
Even if you stayed at the scene and exchanged information, not filing the required accident report with your state’s motor vehicle agency can result in license suspension until the report is submitted.
The financial consequences matter too. Your insurer may deny a claim you file weeks later if you never reported the accident when it happened. And if the other driver files a claim first and you have no report on record, you’ve given them control of the narrative. The few minutes it takes to call police or fill out a form is cheap protection against all of that.
