Wyoming Car Accident Laws: Fault, Insurance, and Your Claim

Wyoming is an at-fault (tort) state that follows modified comparative negligence with a 51% bar, meaning the driver responsible for a crash pays and your recovery is reduced by your share of fault, but you are completely barred from recovery if you are 51% or more at fault.

Is Wyoming a no-fault or at-fault state?

Wyoming is a traditional at-fault (tort) state. There is no personal injury protection (PIP) requirement and no no-fault statutory framework of any kind. Title 31, Chapter 9 of the Wyoming Statutes is the Motor Vehicle Safety-Responsibility Act (W.S. 31-9-101 et seq.), a fault-based financial-responsibility system: the driver who caused the crash, and that driver's liability insurer, pays for the other party's injuries and property damage.

Because Wyoming is not one of the twelve traditional no-fault states (Florida, Michigan, Minnesota, New York, North Dakota, Hawaii, Kansas, Kentucky, Massachusetts, New Jersey, Pennsylvania, and Utah), injured drivers do not file against their own policy first. Instead, you pursue a claim directly against the at-fault driver's liability insurer. There is no verbal or monetary injury threshold to clear before suing for pain and suffering, and you do not need to exhaust any first-party coverage before bringing a tort claim.

This system is straightforward in one sense: whoever caused the accident is financially responsible. In practice, however, liability is often disputed, and the at-fault driver's insurer has every incentive to minimize your payout. Understanding how Wyoming's comparative-fault rule works is critical before you accept any settlement offer.

How fault is shared: Wyoming's negligence rule

Wyoming follows modified comparative negligence with a 51% bar, codified at W.S. 1-1-109. Under this rule, your damages are reduced in proportion to your own share of fault, but you lose your right to recover entirely if a fact-finder determines you were 51% or more responsible for the accident.

For example, if you suffered $100,000 in damages but were found 30% at fault, you recover $70,000. If you were found 51% at fault, you recover nothing. This is a meaningful distinction from states that use a 50% bar: in Wyoming you can be equally at fault (50%) and still recover, but tipping to 51% wipes out your claim.

Because the at-fault driver's insurer will try to push your fault share above 50%, the evidence you preserve immediately after a crash (photos, witness statements, police reports) directly affects how much you can recover. An attorney can help you challenge inflated fault attributions before they become part of a settlement agreement.

Minimum car insurance in Wyoming

Wyoming law requires every motor vehicle registered in the state to be covered by liability insurance meeting the 25/50/20 minimums set in W.S. 31-9-102(a)(xi) and enforced under the Motor Vehicle Safety-Responsibility Act (W.S. 31-9-401 to 31-9-415). Those minimums are: $25,000 for bodily injury or death of one person per accident, $50,000 for bodily injury or death of two or more persons per accident, and $20,000 for property damage per accident.

Note that Wyoming's property-damage minimum is $20,000, which is lower than the $25,000 minimum found in many other states. If your vehicle or other property is worth more than $20,000, the at-fault driver's policy may not fully cover your loss even if the driver carries the minimum required coverage.

Every liability policy issued in Wyoming must also include uninsured-motorist (UM) bodily-injury coverage at the same 25/50 limits, unless the named insured rejects the coverage in writing (W.S. 31-10-101). UM also covers you when the at-fault driver's insurer is insolvent (W.S. 31-10-102). Underinsured-motorist (UIM) coverage is not separately mandated and is typically offered as an optional add-on. Wyoming does not require PIP, and MedPay coverage (which pays your own medical bills regardless of fault) is entirely optional.

How long you have to file: the statute of limitations

Wyoming's general personal-injury statute of limitations is 4 years from the date of the crash. This deadline is set by W.S. 1-3-105(a)(iv), which covers actions for injury to the rights of a plaintiff not arising on contract and not otherwise enumerated. Both bodily-injury and property-damage claims from a negligence-based auto accident fall within this 4-year window.

There are important exceptions. Wrongful-death claims arising from a fatal crash carry a separate 2-year statute of limitations under W.S. 1-38-102(d). If any defendant is a government entity (a city, county, or state agency), the Wyoming Governmental Claims Act imposes much shorter notice and filing requirements. Missing a government-claim notice deadline typically bars the claim entirely, regardless of the general civil statute of limitations.

Missing the applicable deadline almost always bars your claim permanently. If you are unsure whether a government entity is involved, or if a loved one died in the crash, consult a Wyoming attorney well before the 2-year mark.

What a Wyoming car accident claim is worth

The value of a Wyoming car accident claim depends on your economic damages (medical bills, lost wages, future care costs, vehicle repair or replacement) and non-economic damages (pain and suffering, emotional distress, loss of enjoyment of life). Wyoming does not cap non-economic damages in personal-injury cases, so serious injuries can support substantial non-economic awards.

Your recovery is then reduced by your share of comparative fault under W.S. 1-1-109. A 20% fault finding on a $200,000 claim reduces your net recovery to $160,000. The final amount you actually receive is also constrained by the at-fault driver's policy limits: if that driver carries only the 25/50/20 minimums and your damages exceed $25,000, you may need to look to your own UM/UIM coverage (if you purchased it) or pursue the driver's personal assets.

What to do after a car accident in Wyoming

Taking the right steps immediately after a crash protects both your health and your legal claim.

First, make sure everyone is safe and call 911 if there are injuries. Wyoming law requires you to report any accident involving injury, death, or property damage above a certain threshold to law enforcement, and the police report is an important piece of evidence.

Document everything at the scene. Photograph all vehicles, damage, skid marks, road conditions, traffic controls, and any visible injuries. Get the names, contact information, and insurance details of everyone involved, and note the names and contact information of any witnesses. Do not discuss fault at the scene.

Seek medical attention as soon as possible, even if you feel fine. Adrenaline masks pain, and some serious injuries (including concussions and soft-tissue damage) may not present symptoms for hours or days. A gap in treatment is one of the most common arguments insurers use to minimize injury claims.

Notify your own insurer that the accident occurred, but be cautious about giving recorded statements to the at-fault driver's insurer before speaking with an attorney. Insurers will use your words to raise your comparative-fault share above the 51% bar. A Wyoming personal-injury attorney can help you present your claim in the strongest possible light before you accept any settlement offer.
