Deer Collision Liability Laws in Colorado: Fault, Insurance, and Reporting Rules
October 31, 2026
In most crashes, someone is legally at fault. In a typical Colorado deer collision, nobody is. When wildlife causes the damage, usually no one is at fault, because no owner can be held responsible for nature. That doesn’t mean the bill disappears.
Deer collision liability laws in Colorado come down to a few questions. Who pays for repairs? What happens if you swerve and hit something else? Do you have to call the police? Can you take the deer home? This article answers each one so you know where you stand before it happens on I-70, Highway 82, or a back road at dusk.
The risk is real. A Colorado law firm citing Colorado Department of Transportation (CDOT) data reports about 3,300 wildlife hits per year on average over a ten-year span. That figure comes from an older summary, so treat it as a rough scale rather than a current count.
Who Is Liable When You Hit a Deer in Colorado
As a driver, you are almost always responsible for your own vehicle damage and injuries after hitting a deer. Responsibility for vehicle damage or injuries from hitting an animal typically falls on the driver and their insurance. A wild mule deer (Odocoileus hemionus) has no owner, so there is no one to bill.
The law also doesn’t treat a deer as a predictable hazard. Drivers must leave enough following distance to stop for things ahead, but animals that dart into traffic are not predictable obstructions drivers can avoid. A Colorado auto accident law firm notes that hitting an animal can still count as an at-fault accident in some circumstances.
Fault can shift to another person in a few situations. A negligent owner can be liable for domesticated animals, and your own speeding can count against you. If a negligent owner let an animal roam freely, that person may be held liable, and a speeding driver may share the blame.
| Scenario | Who Usually Bears the Loss |
|---|---|
| Deer runs into your path and you hit it | You, through your own insurance |
| You swerve and hit another car, cyclist, or pedestrian | You may be found at fault for that second collision |
| You rear-end a driver who braked for a deer | Usually you, as the following driver |
| Livestock owner let animals onto a roadway | The owner may share fault, depending on the facts |
Livestock is the main exception. Colorado follows comparative negligence rules, so a livestock owner and a driver can share fault for a crash. If the animal you hit was a cow or horse rather than a deer, read our guide to open range laws in Colorado.
Does Car Insurance Cover Deer Collisions in Colorado
It does, but only if you carry the right coverage. Full coverage pays for a deer collision only when it includes comprehensive insurance. According to the Insurance Information Institute, comprehensive coverage usually pays for animal damage in Colorado.
Liability-only policies leave you with the repair bill. Liability insurance applies to other drivers when you are responsible for an accident, and it does not cover collisions with deer or other animals. Medical bills are a separate question, and your health insurance or medical payments coverage usually handles them.
- Comprehensive: Covers damage to your car from a deer strike, minus your deductible.
- Collision: Covers crashes with other vehicles or objects, and may come into play if you swerve into a guardrail or tree, depending on your insurer.
- Liability: Pays for other people’s injuries and property damage, not your own car.
Premiums are another worry. Many insurers don’t raise rates after comprehensive claims because deer accidents are seen as unavoidable. Whether yours does depends on the insurer and state law, so ask before you file.
Pro Tip: Call your agent and ask how your policy classifies a crash where you swerve and hit a fixed object. Some insurers treat it as a comprehensive animal claim and others treat it as a collision claim, which can change your deductible and your rates.
Who Is at Fault If You Swerve to Avoid a Deer in Colorado
Swerving is where deer collisions turn into fault disputes. If you swerve to avoid wildlife and hit another car, cyclist, or pedestrian, you may be found at fault for that accident. The deer didn’t hit anyone. Your steering input did.
Hitting a fixed object is usually a single-vehicle crash with no other party to blame. You would still pay through your own collision or comprehensive coverage. In a serious case, an officer could cite you for careless driving if the swerve put others at risk.
Swerving can also be the wrong call physically. Local reporting on Colorado deer crashes advises drivers not to swerve if a deer runs out in front of them. Braking hard in your lane is generally safer than a sudden turn into oncoming traffic or a ditch.
Colorado courts weigh a driver’s reaction to a sudden emergency, so a reasonable split-second choice carries some protection. It isn’t a guarantee. If you hit another vehicle, expect that driver’s insurer to look hard at whether you had a safer option.
What To Do After a Swerve Crash
- Check yourself and your passengers for injuries and call 911 if anyone is hurt.
- Move to a safe spot if the car is drivable, and turn on your hazard lights.
- Exchange insurance and contact details with any other driver involved.
- Photograph the road, the vehicles, skid marks, and the deer if it is safe to do so.
- Get a police report number before leaving the scene.
Is It Illegal to Hit a Deer and Drive Off in Colorado
Hitting a deer is not a crime. Leaving the scene of a reportable crash can be. A Denver personal injury firm notes that hitting a deer isn’t a criminal act, but leaving without calling could create unexpected issues. Failing to report an accident and leaving the scene can lead to fines or even a criminal charge.
The key detail is that a wildlife strike counts as a crash. Even if the animal runs off, a wildlife collision is legally a crash in Colorado. If your car is damaged or anyone is hurt, you should stay and report it rather than drive away.
There is one narrow point where driving off is fine. If you hit a deer and your car is undamaged and nobody is hurt, you don’t need to call Colorado Parks and Wildlife (CPW) about the animal. Someone who hits a deer and doesn’t want the carcass isn’t required to call CPW.
Common Mistake: Assuming a car that “seems fine” means you can skip the report. Hidden damage often shows up later, and an insurer may question a claim with no police record behind it.
Deer Collision Reporting Requirements in Colorado
Colorado’s accident reporting law applies to deer crashes the same way it applies to any other. One Colorado news outlet cites C.R.S. §42-4-1606 as the statute requiring the driver to report. Colorado requires drivers to report any crash that results in injury, death, or property damage.
Even when the damage is minor, a report helps you. A report creates an official incident record, and your insurer may review the police report to process your claim. Prompt reporting also lets authorities deal with an animal that is still a danger to other drivers.
Several agencies may respond. Colorado Parks and Wildlife, Colorado State Patrol, and CDOT are generally the three agencies involved in roadkill response. State Patrol is often first on scene, and CDOT handles disposal of carcasses. For the full picture on handling animals found on roads, see our roadkill laws in Colorado article.
Steps to Take After the Crash
- Pull over safely, turn on your hazard lights, and check that passengers are okay.
- Don’t approach the animal, because Colorado Parks and Wildlife warns it may kick or bolt.
- Call local law enforcement or Colorado State Patrol and ask for an incident number.
- Photograph the scene, look for witnesses, and save the responding officer’s case number and contact information.
- Contact your insurer to open a claim.
Can You Keep or Salvage a Deer You Hit in Colorado
Yes, with a free permit. CPW sets the rules for roadkill in Colorado, and a driver who strikes and kills an animal can get a permit to legally take the carcass home. The permits are free.
The rules depend on the animal. Deer, elk, and antelope can be kept, but Parks and Wildlife must be notified. Small animals like squirrels, skunks, raccoons, and rabbits can be collected without reporting. Elk (Cervus canadensis) fall under the same large-game permit rules as deer.
| Animal Type | Permit Needed? | Notes |
|---|---|---|
| Deer, elk, moose, antelope | Yes, free from CPW | Contact CPW promptly; antlers stay with the state |
| Squirrels, skunks, raccoons, rabbits | No | No report required |
How fast you must call is where sources disagree. One report says CPW should be called within 48 hours of the strike. A Grand Junction newspaper quoting CPW staff says someone has five days to contact the agency.
Important Note: Published timelines for Colorado salvage permits range from 48 hours to five days. Treat 48 hours as the safe deadline and call CPW or local law enforcement as soon as you can.
You can also get permission on the spot. Some state patrol officers and county sheriff’s offices may issue permits depending on where the incident happens. You will need to give the location, plus the sex and type of animal, and an officer may check that it was actually hit rather than poached.
Antlers don’t come with the meat. A CPW officer explained that the permit doesn’t cover antlers, which remain state property to discourage people from using permits to take only the antlers. If you don’t want the carcass, CPW in some areas keeps a donation list and calls the first person on it to collect the animal.

Can You Sue the State or Local Government Over a Deer Collision in Colorado
Almost never. Wild deer belong to no one, and Colorado public entities are protected by the Colorado Governmental Immunity Act. Governments can be sued only where the statute waives that immunity, such as certain dangerous conditions of a public road.
A deer crossing a highway is not normally a dangerous road condition. A claim might have a chance if poor road maintenance, missing signage, or a defect made the crash worse. A deer strike alone, on a road that is otherwise sound, rarely meets that standard.
If you do pursue a claim, the notice rules are strict. Colorado generally requires written notice to the public entity within 182 days of discovering the injury, and damages against public entities are capped by statute. Missing the notice window can end a claim before it starts.
- Document road conditions, signs, and any visible defects with photos.
- Note whether a wildlife crossing sign or fencing was present or damaged.
- Keep repair estimates and medical records together.
- Speak to a Colorado personal injury attorney before the notice deadline passes.
Colorado manages wildlife through CPW rather than treating deer as anyone’s property. Our guide to nuisance wildlife laws in Colorado explains what that means for property owners and agencies.
Time Limits for Deer Collision Injury Claims in Colorado
Deadlines depend on who you are claiming against. For most motor vehicle injury lawsuits in Colorado, the statute of limitations is generally three years from the date of the crash. Other tort claims can have a shorter two-year limit, so don’t assume.
| Type of Claim | General Deadline |
|---|---|
| Injury lawsuit from a motor vehicle crash | Three years from the crash |
| Notice of claim to a public entity | 182 days from discovering the injury |
| Insurance claim under your own policy | Set by your policy; report promptly |
Your insurance policy has its own clock. Most policies require prompt notice, and a late report can give the insurer grounds to dispute a claim. File within days, not months.
Suits in deer cases are rare because there is usually no defendant. They tend to arise when a swerve injures another person, or when a negligent owner is involved. Colorado’s modified comparative negligence rule also applies: if you are found 50 percent or more at fault, you can’t recover damages.
Treat these deadlines as general guidance, not legal advice. A Colorado attorney can confirm which limit applies to your facts, especially if a government entity is involved.
Important Note: This article is general legal information, not legal advice. Colorado statutes and deadlines can change, and your case may turn on specific facts. Consult a licensed Colorado attorney or your insurer before relying on any deadline or coverage detail here.
If you hit a deer in Colorado, call law enforcement, document the scene, and contact your insurer within a day. Check that your policy includes comprehensive coverage before deer season, when collision risk peaks.
