Deer Collision Liability Laws in Michigan: Who Pays, Who’s at Fault, and What to Report
October 22, 2026
Hitting a deer in Michigan is rarely anyone’s legal fault, yet it can still cost you thousands of dollars. Deer collision liability laws in Michigan come down to three questions: who is responsible, which insurance coverage pays, and what you must do afterward. According to the Michigan State Police, nearly 58,000 vehicle-deer crashes occurred in 2024, with 80% of them on two-lane roads, mostly around dusk and dawn.
The answers change depending on whether you hit the deer, swerved and hit something else, or injured another driver in the process. This article walks through each scenario in plain terms, so you know where you stand before you call your insurer or an attorney.
Important Note: This article is general legal information, not legal advice. Michigan insurance and tort rules have changed in recent years, so confirm the details of your situation with a licensed Michigan attorney or your insurer.
Who Is Liable When You Hit a Deer in Michigan
In most cases, nobody is. The white-tailed deer (Odocoileus virginianus) is a wild animal with no owner, and Michigan drivers are generally not held legally liable for hitting a deer, because collisions with wildlife are typically viewed as unavoidable accidents. That means you generally cannot be sued for damages simply because a deer ran into your car.
The flip side is that you also have no one to bill. Because no at-fault driver is involved, people injured in deer crashes cannot recover pain and suffering compensation, uninsured or underinsured motorist benefits, or mini tort money for repair costs. Your own policy is the only source of payment.
Your behavior still matters. If a driver is negligent, such as speeding, driving distracted, or driving drunk, that can affect their liability. If a deer strike causes you to hit a second vehicle, a court will ask whether you were driving safely for conditions.
When an Owner Can Be Responsible
The rules change when the animal has an owner. When a motorist hits a domesticated animal or livestock that wanders into the road, the owner who negligently let it loose is clearly liable. Our guide to Michigan livestock fence laws explains what farm owners must do to keep animals off the road. If a loose dog caused your crash, the leash laws in Michigan may help you identify who is responsible.
Does Car Insurance Cover Deer Collisions in Michigan
Yes, but only if you carry the right coverage. Michigan deer crashes are covered by No-Fault insurance for medical treatment and by comprehensive coverage for vehicle damage. The required coverages do not pay for your car on their own.
The three mandatory coverages are rarely enough to pay for damage from a deer strike, so you need optional coverage in place. Those options are optional under Michigan law, but a bank may require them if your vehicle is leased or financed.
| Coverage | What It Pays for in a Deer Crash | Required in Michigan? |
|---|---|---|
| Comprehensive | Repairs to your car after you strike the deer, minus your deductible | No, optional |
| Collision | Damage when you swerve and hit an object or another vehicle | No, optional |
| Personal Injury Protection (PIP) | Medical bills, lost wages, and replacement services for you and passengers | Yes, with limits set by your policy |
| Liability | Injuries and damage you cause to others, which rarely applies to a deer strike alone | Yes |
One detail often surprises drivers. A deer strike is covered even if you skipped collision coverage on an older car, as long as you carry comprehensive. If you carry only the state-required liability coverage, you pay for your own vehicle’s damage out of pocket.
Will a claim raise your premium? A deer strike is not considered an at-fault accident under Michigan law, so it typically will not push premiums up the way a driver-caused collision might. Your insurer’s own rating rules still apply, so ask your agent before you file.
Pro Tip: Check your declarations page for a comprehensive line item before deer season. Comprehensive deductibles are often lower than collision deductibles, so how the claim is classified can change what you pay.
Who Is at Fault If You Swerve to Avoid a Deer in Michigan
Swerving changes everything. If you swerve and hit another vehicle, a guardrail, or a tree, you are no longer in a deer-strike situation. The driver who swerves or loses control is likely held responsible for any property damage or injuries.
Insurers treat it the same way. If you swerve and hit a tree, ditch, fence, or another vehicle without touching the deer, the claim is a collision claim because your car struck an object. Your collision deductible applies, and you may be considered at fault for leaving your lane, which can affect your rates.
What Happens If You Hit Another Car
Michigan’s no-fault system handles most of the cost. If the crash happened in Michigan, the other driver’s no-fault insurance pays for damage to their vehicle and any injuries. You may still be responsible for serious injuries, deaths, or permanent disfigurement, and for damages if the crash involves another state or a vehicle not registered in Michigan.
Fault also affects what you can recover. Michigan uses modified comparative negligence, so you can seek compensation from another driver only if you are less than 50% responsible. Any award is reduced by your percentage of fault.
Common Mistake: Swerving hard at highway speed. Safety guidance warns that swerving can lead to hitting another car or a tree, and advises braking firmly and staying in your lane if a collision is unavoidable.
Is It Illegal to Hit a Deer and Drive Off in Michigan
It depends on what else happened. If you hit only a deer and your car is safe to drive, driving away is not the problem. If the deer runs off, you can leave the scene and report the collision from a safe location.
Another vehicle changes the rules. If you hit or cause a crash with another car, you cannot leave even if you report the deer, and leaving before authorities arrive is a misdemeanor under Michigan law. Section 257.618 of the Michigan Vehicle Code lists penalties of a $100 fine, 90 days in jail, or both. You can read more on the penalties for leaving a deer crash scene from that law firm.
Moral and practical duties apply too. If you hit someone’s pet instead of a deer, stopping matters, and our guide to animal cruelty laws in Michigan covers the duties around injured animals. A badly hurt deer on the shoulder can also endanger the next driver, so calling it in is the safer choice.
Deer Collision Reporting Requirements in Michigan
Sources disagree on whether you must report a deer crash to police. One Michigan law firm states the law does not require a police report after a crash with a deer. An insurance agency, meanwhile, says Michigan law requires reporting a crash involving injury or $1,000 or more in property damage, which almost any deer strike reaches.
Important Note: Because of that conflict, treat a police report as mandatory for practical purposes. Call the police whenever there is an injury, significant damage, or another vehicle involved.
Even if the law is unclear, the paperwork helps you. Your insurer may need a police report number to start your claim, and the report is proof that you have an animal-strike claim rather than a collision claim. A deer left in the road can also threaten other drivers until it is removed.
Steps to Take After the Crash
- Pull over safely, call 911, and do not approach the animal, since deer can be unpredictable and may still be alive.
- Photograph your vehicle, the road, the lighting, and the deer if it is safe to do so.
- Get a police report number.
- Notify your insurance company promptly, but avoid recorded or detailed statements until you understand your coverage.
Photos matter more than most drivers expect. They can help prove whether the crash was a direct impact or a swerve, which decides whether comprehensive or collision coverage applies. A summary from a Michigan injury firm covers these steps in more detail.
Can You Keep or Salvage a Deer You Hit in Michigan
Many drivers assume a deer that hits their car is theirs to take home. In Michigan, wildlife belongs to the state, so you should not load a carcass into your truck without checking the rules first. The process generally involves contacting law enforcement or the Department of Natural Resources and getting permission before you take possession.
Taking a deer without authorization can lead to a wildlife violation, and the meat may not be safe to eat. Our roadkill laws in Michigan page explains who can claim road-killed animals and how the permission process works. Confirm the current steps with the responding officer or the DNR before you act.
Pro Tip: Ask the responding officer about salvage while you wait for your police report number. It is the fastest way to get an answer for the stretch of road where your crash happened, and you can document the permission on the report.
Can You Sue the State or Local Government Over a Deer Collision in Michigan
In nearly every case, no. Michigan’s governmental tort liability law gives state and local agencies broad immunity, with a narrow exception for failing to keep a roadway in reasonable repair. A deer is not a road defect, and neither the state nor a county road commission controls wild deer.
That leaves few realistic claims. A lawsuit might be possible if poor maintenance, such as a missing guardrail or a large pothole, contributed to a crash caused partly by a deer. You would also need to show the agency knew about the defect. These cases are hard to win.
Private owners are a different matter. If the animal that caused your crash was a captive or farmed deer, or a pet or livestock animal, its owner may be liable for negligent containment. For dogs and other pets, see our overview of pet laws in Michigan.
Time Limits for Deer Collision Injury Claims in Michigan
Deadlines depend on which claim you are making. Missing one can end your claim even if the facts are in your favor. The table below summarizes the main Michigan deadlines as generally understood, but have an attorney confirm which apply to you.
| Type of Claim | Typical Deadline | Notes |
|---|---|---|
| No-fault PIP benefits | About one year to notify your insurer | Benefits you can recover may be limited to one year before you file suit |
| Comprehensive vehicle damage | Set by your policy | Report promptly, since policies require timely notice |
| Negligence claim against another driver | Three years for personal injury | Applies if you were hurt in a swerve crash caused by someone else |
| Claim against a government agency | Written notice within 120 days | Applies to road-defect claims under the highway exception |
Injured passengers have options too. An injured passenger’s medical bills are covered under their own No-Fault or health policy, and uninsured passengers may apply to the Michigan Assigned Claims Plan. MACP PIP medical benefits have a coverage limit of $250,000.
If you are unsure which deadline applies, start with a written notice to your insurer and a consult with a Michigan attorney. Most injury lawyers offer free case reviews. For background on how Michigan deer crashes are insured, that firm’s overview is a useful companion read.
Deer season runs hard from fall into winter, so it pays to review your policy and save your insurer’s claim number in your phone now. If a crash happens, stay safe, document everything, and report it. Those three habits protect your claim far more than any argument about fault.
