Wyoming Car Accident Laws

Wyoming's four-year deadline is genuinely generous, and its constitutional protection against damage caps puts it in the same small category as Arizona — most states leave this door open for the legislature; Wyoming and Arizona have closed it.

The Wyoming Constitution doesn't just fail to cap damages — it explicitly forbids the legislature from doing so, a protection most states don't have.

Statute of limitations: 4 years

Under Wyo. Stat. §1-3-105, you generally have four years from the date of the accident to file a personal injury or property damage lawsuit — notably longer than the two-year deadline common in most states. Wrongful death claims carry a shorter, two-year deadline.

Fault rule: modified comparative negligence, 51% bar

Under Wyo. Stat. §1-1-109, you can recover damages if you're found 50% at fault or less, reduced by your percentage. At 51% or more, you recover nothing.

Insurance and Wyoming's constitutional protection

Wyoming is an at-fault state. Minimum liability limits are 25/50/20: $25,000 per person and $50,000 per accident for bodily injury, plus $20,000 for property damage. Notably, the Wyoming Constitution (Art. 10, §4(a)) prohibits the legislature from capping personal injury damages — a genuine protection most states don't share. Claims against the government are still capped, at $250,000 per person / $500,000 in aggregate.

How this plays out in a real claim

Take an intersection collision where fault is genuinely disputed. If an insurer or court assigns you 40% of the blame, Wyoming's rule still lets you recover 60% of your damages, and even at exactly 50% you still recover half. But at 51% or more, the claim is barred entirely — not reduced, eliminated. That one-point difference between 50% and 51% is exactly why insurers have a real incentive to push a borderline case just over the line rather than simply discount what they pay.

A mistake worth avoiding in Wyoming

Because a single percentage point at the 51% threshold can be the entire difference between a reduced payout and nothing at all, careless statements at the scene or to an adjuster carry more weight here than in a pure comparative state. Avoid speculating about fault, even casually, until the full picture — police report, witnesses, any available footage — is in front of you.

If a government vehicle or agency was involved

Wyoming requires written notice of claim within two years under the Governmental Claims Act (Wyo. Stat. §1-39-113) — the same as the general window — but once that notice is filed, suit must follow within one year of it (§1-39-114), effectively layering a second, tighter deadline on top of the first.

If the crash resulted in a death

Wyoming's wrongful death deadline is two years, measured from the date of death (Wyo. Stat. §1-38-102) rather than from the date of the underlying accident — shorter than the four-year window for an ordinary injury claim in this state.

Beyond the deadline and the fault rule

The statute of limitations and the fault rule above decide whether you have a claim and how much of it survives — they don't decide what the claim is actually worth, or whether it's worth handling yourself. For that, see our guides on what affects a settlement, who pays your medical bills while a claim is pending, and whether Wyoming law makes a lawyer worth it for your specific situation.

When it's worth talking to someone

With a hard cutoff at 51% and no cap on what a jury could award, how fault gets assigned in Wyoming carries real weight. A free, no-obligation conversation is worth having if fault is disputed.
