Deer Collision Liability Laws in Wyoming: Who Pays, Who Reports, and Who Can Be Sued
November 6, 2026
Drivers are involved in more than 6,000 wildlife collisions on Wyoming roadways each year, and 80 to 85 percent of them involve mule deer. Wyoming Game and Fish also says its numbers undercount the real total, because most people only report a crash if the vehicle is badly damaged or the deer died on impact.
Deer collision liability laws in Wyoming are simpler than most drivers expect, but the details trip people up. There is no deer owner to sue, your insurance policy decides who pays, and a few reporting and salvage rules carry real penalties if you ignore them.
This article walks through each question you are likely to face after a crash, from fault and coverage to reporting, salvage, and filing deadlines. It is general education, not legal advice for your situation.
Who Is Liable When You Hit a Deer in Wyoming
In most cases, nobody is legally liable. A mule deer (Odocoileus hemionus) is a wild animal with no owner, so there is no one to bill for the damage to your vehicle. You absorb the loss, and your own insurance is usually the only source of repayment.
Elk (Cervus canadensis) and moose (Alces alces) work the same way. Wyoming also uses a fault-based system. Under that system, the party responsible for causing a car accident is also responsible for the resulting harm. A deer is not a party you can hold responsible, but another driver can be.
| Scenario | Who Usually Bears the Loss |
|---|---|
| You hit a deer that ran into the road | You, through your own comprehensive coverage if you carry it |
| A tailgating driver rear-ends you after you brake for a deer | The tailgating driver and their liability insurer |
| Another motorist hits the deer, which then strikes your car | Usually you, through comprehensive coverage, unless the other driver was negligent |
| The animal you hit is someone’s livestock | Depends on fencing and range status; see the open range laws |
Livestock is a different story from wildlife. If the animal wore a brand or came through a broken fence, ownership and fencing duties can shift the blame. Our breakdown of cattle trespass rules covers who owes what when a neighbor’s animals wander onto the road.
Does Car Insurance Cover Deer Collisions in Wyoming
Only if you carry the right coverage. Wildlife collisions are covered under comprehensive coverage, not collision coverage, and Wyoming law does not require comprehensive. A driver with liability-only insurance is paying for the repairs out of pocket.
The stakes are real. According to Insuranceyo’s 2026 Wyoming auto guide, a wildlife collision claim averages $4,000 to $8,000. The same guide says comprehensive coverage often adds only $15 to $25 a month to a typical Wyoming vehicle’s premium. Your own quote will differ, so treat those figures as a benchmark, not a promise.
| Coverage Type | Role After a Deer Collision |
|---|---|
| Comprehensive | Pays for damage from striking the animal, minus your deductible |
| Collision | Pays if you swerve and hit a tree, guardrail, or another vehicle |
| Medical Payments | Covers medical bills for you and your passengers regardless of fault |
| Liability only | Pays nothing for your own vehicle or injuries in a deer strike |
Pro Tip: Photograph the vehicle damage, the carcass, and the road before you leave the scene. Insurers often ask for proof that an animal strike caused the damage, and a police or highway patrol report helps your claim.
Who Is at Fault If You Swerve to Avoid a Deer in Wyoming
If you swerve and hit another vehicle, you can end up at fault even though the deer started the chain of events. Courts look at whether a reasonable driver would have acted the same way in that emergency, and swerving across a centerline is hard to defend. If you leave your lane and strike a tree or guardrail, you are the only party involved, and collision coverage is the policy that responds.
Fault also affects what you can recover. Wyoming follows a modified comparative fault model under Wyo. Stat. § 1-1-109. A plaintiff is barred from recovery unless they are 50% or less responsible. Any award shrinks by your share of the blame.
Braking firmly in your own lane is usually the safer choice, both for your body and for a later fault dispute. Game and Fish points to speed as the biggest factor, noting that drivers often do not see deer before a collision, so slowing down during dawn and dusk avoids many crashes.
Important Note: Sources describe Wyoming’s fault cutoff in slightly different words, with some saying “less than 50%” and others saying “50% or less.” Ask a Wyoming attorney how the statute applies to your facts if the exact percentage matters.
Is It Illegal to Hit a Deer and Drive Off in Wyoming
Driving away is not automatically a crime, but it can become one if the crash triggers a reporting duty. Wyoming requires a driver to report a collision involving injury or death, or apparent property damage of $1,000 or more. A deer strike that breaks a headlight and crumples a hood can clear $1,000 quickly.
I did not find a Wyoming statute that makes leaving the scene after hitting a deer an offense on its own. Hit-and-run rules are written around people, vehicles, and property. If your crash involves a passenger injury, a second vehicle, or damage to a fence or road sign, you cannot just drive off.
There is also a practical reason to stay. Many deer look fine but later die off the road from broken bones. Reporting the animal’s location lets responders deal with it humanely and clear it from the road.
Deer Collision Reporting Requirements in Wyoming
The legal trigger is damage or injury. Wyoming law does not require reporting a wildlife collision unless property damage exceeds $1,000 or someone is hurt, but reporting is advisable for insurance purposes. In practice, nearly every deer collision that damages your vehicle should be reported.
- Move to a safe spot and turn on your hazard lights. Do not try to move a dead animal from the roadway, because it can be extremely dangerous.
- Call for help. Game and Fish encourages drivers to report wildlife crashes to Wyoming Highway Patrol dispatch at 1-800-442-9090. Call 911 for injuries.
- Tell the dispatcher whether the animal is still in the road. The Wyoming Department of Transportation advises remaining buckled in if possible, in case another vehicle causes a secondary crash.
- Collect names, photos, and the responding officer’s report number.
- Notify your insurer promptly and ask whether your policy sets its own reporting window.
The state’s wildlife data depends on these calls. A report also protects you if the damage turns out to be larger than it first looked.
Can You Keep or Salvage a Deer You Hit in Wyoming
Yes, but only with advance authorization. Collecting roadkill from select Wyoming roadways became legal in January 2022, and people can request authorization to salvage deer, elk, antelope, moose, wild bison, or wild turkey from unintentional collisions. The rule applies to accidents, not to animals you hit on purpose.
As of November 2025, Game and Fish requires approval through the Wyoming 511 app before collection, and the app works even without cellular service. The department’s road-killed wildlife notice lists these safety conditions:
- Take the animal only from sunrise until sunset.
- Park off the road, use emergency flashers, and do not field dress the animal on the roadway.
- Take the whole animal and dispose of inedible portions in an approved landfill.
- Interstates 25, 80, and 90 are off limits, along with active construction zones and national parks.
The regulation also covers what happens afterward. According to the Game and Fish road-killed wildlife rule, the head and all portions of the spinal column must go to an approved landfill or incinerator in Wyoming. That rule exists mainly to limit the spread of chronic wasting disease.

Can You Sue the State or Local Government Over a Deer Collision in Wyoming
You can try, but these claims are hard to win. Wyoming’s Governmental Claims Act protects state and local governments from most lawsuits and allows them only in limited situations. The presence of wildlife near a road, by itself, is not usually enough.
A stronger claim points to something specific the government did or failed to do, such as a road defect or a hazard it created. Researchers who studied the issue for the state noted that they evaluated the location of wildlife warning signs in relation to areas with high collision rates. Signage debates like that show up in policy discussions, but they rarely turn into winning lawsuits for individual drivers. The WYDOT-commissioned federal report also estimated $11,600 in injury and property damage costs per reported collision, based on 2008 to 2013 data.
Timing is the biggest trap. A claim against the government has a two-year limit, and a formal written notice of intent to file must be provided within that time. If you suspect a road condition contributed to your crash, talk to an attorney well before that window closes.
If the problem is a nuisance animal population rather than a road defect, the remedies are different. Our overview of nuisance wildlife laws in Wyoming explains what landowners and agencies can actually do.
Time Limits for Deer Collision Injury Claims in Wyoming
For most claims against a private party, you have four years. Wyoming’s statute of limitations for most personal injury claims is four years from the date of injury, covering car accidents and other negligence-related cases. That applies, for example, if a negligent driver caused your injuries while you reacted to a deer.
| Type of Claim | Deadline |
|---|---|
| Personal injury against a private party | 4 years from the injury |
| Vehicle or property damage from negligence | 4 years |
| Wrongful death | 2 years from the date of death |
| Claim against a government entity | 2 years, with written notice |
| Insurance claim on your own policy | Set by your policy; report as soon as possible |
The four-year period for property damage comes from Wyoming Statute § 1-3-105(a)(iv). The shorter wrongful death window is confirmed by the Fitzgerald Law Firm, which says it runs two years from the decedent’s death.
Exceptions can extend or pause the clock. Tolling can apply for minors, legal disabilities, delayed discovery, or when a defendant flees the state. These exceptions depend heavily on the facts, so do not count on them.
Important Note: This article is general legal information, not legal advice. Deadlines, statutes, and Game and Fish rules can change. For a specific crash, confirm the current rules with a licensed Wyoming attorney or the relevant agency.
Your own insurance deadline is usually the one that arrives first, so call your insurer the same day. Then call Highway Patrol if the damage tops $1,000 or anyone is hurt, and photograph everything. Wyoming’s deer collision liability laws mostly leave the cost with the driver, which makes the right comprehensive coverage and quick, careful reporting your best protection.
