What Happens If You Don’t Call the Police After a Car Accident?
Two drivers agree it was minor, exchange numbers, and go home. A week later one of them has neck pain, the other has stopped answering, and there is no official record that the crash ever happened. That sequence plays out constantly, and it turns a straightforward claim into a fight over whether the collision occurred the way you say it did. Skipping the call also has a legal consequence in Colorado that most drivers do not know about. Our Denver car accident lawyers at Boesen Law can tell you what to do next, whether the crash was yesterday or last month.
Colorado Law Requires You to Report the Crash
This is not a matter of etiquette. Under C.R.S. § 42-4-1606, a driver involved in a traffic accident resulting in injury, serious bodily injury, death, or any property damage must give immediate notice of the location of the accident to the nearest office of the police authority. If the police direct you to do so, you must return to the scene and stay until officers arrive and finish investigating.
The threshold is worth reading twice, because it is not limited to serious crashes. Any property damage triggers the reporting duty, and the Colorado State Patrol runs an online crash reporting system for exactly the collisions no trooper came out to see. And the statute has teeth: a person who violates the section commits a class 2 misdemeanor traffic offense. Separate and more serious penalties apply to leaving the scene entirely.
So the honest answer to whether you were required to call is almost always yes. The duty to call police after a Colorado crash reaches far more collisions than most drivers assume it does.

When an Officer Can Decline to Write a Report
Calling does not guarantee a report, and this surprises people who did everything right. The same statute allows a law enforcement officer to skip the investigation and the written report when there is a reasonable basis to believe property damage to any one person does not exceed one thousand dollars and nobody was injured.
There are two exceptions built into that provision, and both are useful to know while you are standing at the roadside. The officer must complete an investigation and file a report if a participant specifically requests it, or if any participant cannot show proof of insurance. That second exception matters more than it sounds, because an uninsured driver is exactly the person you will later need a record of, and the same gap drives most hit-and-run claims.
If an officer suggests that the damage looks minor and no report is needed, you are entitled to ask for one anyway, and you should. Without the officer’s measurements and diagram, proving how the collision happened later falls to accident reconstruction, which is more work and more expense than a request at the scene would have cost.
What You Lose Without a Police Report
A police report is not the case, but it anchors it. You still have to prove the same elements of a negligence claim either way, and without a report several of them get harder at once.
- Fault becomes a contest of memories. An officer’s diagram, measurements, and statements taken while everyone is still at the scene are close to impossible to replicate later. Insurers weigh them heavily.
- The other driver’s story can change. Admissions made at the scene evaporate when they are not written down by someone neutral, and drivers who apologized on the roadside often deny fault once an adjuster is involved.
- Your injuries look less credible. Adjusters treat an unreported crash as a signal that nothing much happened, and delayed symptoms are already the hardest thing to prove. Whiplash is the classic example, since the pain often arrives the following morning.
- You may not have the other driver’s real information. Names, phone numbers, and insurance details exchanged informally are sometimes wrong, and occasionally deliberately so.
- Citations never issue. A ticket for following too closely or failing to yield is strong evidence of fault in the civil claim, and it only exists if an officer responded.
The Uninsured Motorist Problem
The absence of a report is most damaging when the other driver turns out to have no insurance or when they flee. Uninsured and underinsured motorist coverage is designed for exactly those situations, and it is available on most Colorado policies. But carriers routinely require prompt reporting of the crash to law enforcement as a condition of paying an uninsured motorist claim, particularly in phantom vehicle cases where proving a hit-and-run already depends on evidence gathered in the first days.
An injured driver who skipped the call can find that their own insurer has a documented reason to deny the claim, which is a harsh outcome for someone who did nothing wrong except believe the other driver would be reasonable. If you carry uninsured motorist coverage, protecting your ability to use it is another argument for making the report at the scene.
What to Do If You Already Left Without Calling
The situation is recoverable more often than people assume, and acting quickly matters more than acting perfectly. Much of what a car accident lawyer does in this position is rebuild the record somebody else would ordinarily have created.
- Report the crash now. File a report with the law enforcement agency for the location where it happened, even days later. A late report is meaningfully better than none.
- See a doctor and describe the crash. Medical records that reference the collision and its date create the documentation the police report would have supplied. Head symptoms deserve same-day attention, because a traumatic brain injury can look like ordinary grogginess for the first day or two.
- Write down everything while it is fresh. Time, location, weather, direction of travel, what each driver said, and where the vehicles ended up.
- Photograph both vehicles before repairs. Damage patterns establish the mechanism of the collision and can substitute for measurements you never took.
- Track down witnesses and cameras fast. Nearby businesses and doorbell systems overwrite footage within days.
- Notify your own insurer promptly. Policy notice requirements run on their own schedule, separate from any legal deadline.
The Filing Deadline Has Not Moved
Whatever happened at the scene, the legal clock runs the same way. Colorado gives most motor vehicle injury claims a three-year filing window measured from the collision, set by C.R.S. § 13-80-101, and your policy’s own notice provisions are usually far shorter than that.
Claims built without a police report can still succeed when the rest of the file is strong. Boesen Law has recovered $1,025,000 for a client rear-ended in a four-car crash whose prior spinal injuries were made worse, and $275,000 for a client hurt in a high-speed rear-end collision who developed concussion symptoms and continuing neck pain with numbness in the hands. Our case results reflect what disciplined documentation produces.

FAQs About Not Calling the Police After a Colorado Crash
Is it illegal not to call the police after a car accident in Colorado?
Generally, yes. C.R.S. § 42-4-1606 requires a driver involved in an accident causing injury, death, or any property damage to give immediate notice to the nearest police authority, and violating that section is a class 2 misdemeanor traffic offense. The property damage threshold is what catches people, since it applies even to collisions that look trivial. Leaving the scene without meeting your other duties is a separate and more serious matter.
Can I still file an insurance claim without a police report?
Yes. A police report is powerful evidence, not a prerequisite for a claim, and it has no bearing on the categories of damages you can recover. What replaces it is everything else: photographs of both vehicles, medical records that document the injury and its timing, witness statements, nearby video, repair estimates, and a consistent account from you. Expect the insurer to lean on the missing report to question whether the crash happened as described, which is why the rest of the documentation has to be thorough.
Can I report a Colorado car accident days later?
You can, and you should if you have not already. The statute contemplates immediate notice, so a late report does not erase the earlier violation, but it does create an official record of the collision and its location. Reporting late also does nothing to the separate personal injury time limits, which continue running from the date of the crash. Contact the agency with jurisdiction over the crash site. Officers may take a delayed report or direct you to file a counter report at the station. Being straightforward about why the report is late is better than reconstructing a version that fits the deadline.
What if the other driver asked me not to call the police?
Treat that request as a warning sign. Drivers who ask to keep police out of it are frequently uninsured, driving on a suspended license, impaired, or in a vehicle that is not theirs. The informal arrangement almost always breaks down: the promised payment does not come, the phone number stops working, or the driver denies the crash entirely once your injuries appear. Reporting protects you, and in Colorado it is what the law requires of you anyway.
