Fault system (no-fault vs at-fault) in Wyoming

Wyoming runs on a pure at-fault system. There is no no-fault law here and no personal injury protection (PIP) coverage sold in the state, so after a crash the driver who caused it, and that driver's liability insurer, pays for the harm. You don't turn to your own policy first the way drivers do in Florida or Michigan. You build a claim against the person at fault, and the money follows the blame.

That makes one question decide almost everything about your case: who was at fault, and by how much.

How Wyoming decides who pays

Wyoming uses modified comparative fault with a 50 percent bar. Under Wyo. Stat. 1-1-109, your own share of the blame does not wipe out your claim as long as it is "not more than fifty percent (50%) of the total fault of all actors."¹ If a jury puts you at 50 percent or less, you still recover, but your award drops by your percentage. At 30 percent fault on a $100,000 claim, you collect $70,000.¹

Cross that line and everything changes. A driver found 51 percent or more at fault takes nothing.¹ Because so much rides on a single number, fault fights in Wyoming are rarely about whether you can recover at all. They turn on shaving your percentage down and pushing the other driver's up.

This is also why insurers press comparative fault hard. Every point of blame they pin on you cuts what they owe, so expect an adjuster to look for anything you did that contributed, from your speed to your following distance to whether you were on your phone.

No PIP, so whose insurance pays your medical bills

Because Wyoming has no no-fault system, there is no PIP and no first-party medical benefit that automatically kicks in after a wreck. You have no PIP claim to file and no PIP deadline to miss, because the product does not exist here.

The at-fault driver's bodily injury liability coverage is the primary source of payment. Wyoming sets those minimums at $25,000 for injury or death of one person, $50,000 per accident for two or more people, and $20,000 for property damage, the 25/50/20 limits in Wyo. Stat. 31-9-405(b)(ii).² Those are floors, and they run out fast in a serious crash.

The one first-party coverage that does exist is optional Medical Payments Coverage (MedPay, or MPC). The Wyoming Department of Insurance describes it as coverage that pays medical or funeral costs for you and your passengers regardless of who caused the crash.³ If you bought it, it can cover bills while the fault claim is still being fought, but no law makes you carry it.

When the at-fault driver has too little coverage

Plenty of Wyoming drivers carry only the state minimum, so uninsured and underinsured motorist coverage matters. Wyoming treats the two differently.

Uninsured motorist (UM) coverage is effectively mandatory. Under Wyo. Stat. 31-10-101, no auto liability policy can be issued in the state unless it includes UM protection against bodily injury, sickness, disease, or death caused by an uninsured driver, and the only way out is for the named insured to reject it in writing.⁴ Underinsured motorist (UIM) coverage, which fills the gap when the at-fault driver has some insurance but not enough, is not required at all, and it is not even a mandatory offer. It is a purely optional add-on.⁴ If a driver carrying the $25,000 minimum hits you and your injuries are worth far more, UIM you chose to buy may be the only place the extra money comes from.

What Wyoming lets you collect

Wyoming is unusually protective of injured plaintiffs on one point: it does not cap damages. Article 10, Section 4(a) of the Wyoming Constitution flatly bars the legislature from enacting any law "limiting the amount of damages to be recovered for causing the injury or death of any person."⁵ There is no ceiling on your medical costs, lost wages, or pain and suffering in an ordinary car-crash case. Wyoming voters were asked in 2004 to amend the constitution to allow caps on noneconomic damages in medical-malpractice suits, and that measure failed. The amendment that did pass only lets lawmakers require medical review panels, not damage limits.⁵

Punitive damages are also on the table when the other driver's conduct was bad enough. In Danculovich v. Brown, the Wyoming Supreme Court upheld punitive damages against a driver who was drunk and speeding, holding that willful and wanton misconduct can support such an award while ordinary or even gross negligence cannot.⁶ Drunk driving is the classic fact pattern, and because the constitution bars caps, a punitive award is not limited either.

One thing Wyoming does not give you is a broad claim against the bar or host who served the drunk driver. Wyo. Stat. 12-8-301 immunizes anyone who legally furnishes alcohol from liability for what an intoxicated person later does, and that immunity falls away only when the alcohol was served in violation of Title 12, for example to someone underage.⁷ In most drunk-driving crashes, your claim is against the driver, not the establishment.

The deadline you cannot miss

Wyoming gives you four years to sue over a crash injury. The limit comes from Wyo. Stat. 1-3-105(a)(iv)(C), which sets a four-year clock on "an injury to the rights of the plaintiff, not arising on contract and not herein enumerated," the catch-all that covers negligence injury claims.⁸ Damage to your vehicle and other property runs on the same four-year track under Wyo. Stat. 1-3-105(a)(iv)(B).⁸ Four years feels like a lot right after a wreck, but evidence and witnesses fade, and insurers rarely make their best offer while the clock still favors you.

If you need the official crash report to document fault, request it through the Wyoming crash report page. If your car lost market value even after a solid repair, that is a separate diminished value claim you press against the at-fault driver.

Fault and Wyoming roads

Wyoming winters give the comparative-fault rule real teeth. Cheyenne averages roughly 56 inches of snow a year and Casper more than 76, and I-80 and I-25 ice over and close for wind and whiteouts.⁹ Driving too fast for those conditions can put a slice of the blame on you even when another driver set off the collision, and under the 50 percent rule that slice comes straight out of your recovery.¹

Two-wheel cases carry their own fault wrinkles. Wyoming requires a helmet only for riders under 18, so an adult riding bareheaded has broken no law, though the insurer may still argue a helmet would have reduced the injury.¹⁰ Lane-splitting and filtering between lanes or rows of vehicles are illegal, although two motorcycles may share a single lane side by side by mutual consent.¹⁰ Wyoming's handheld ban reaches only text-based messaging: Wyo. Stat. 31-5-237 makes it a misdemeanor, with a fine of up to $75, to write, send, or read a text on a handheld device while driving, while dialing a number and hands-free use are exempt.¹¹ Proof that the other driver was texting is strong evidence of fault.

If your crash was serious or fault is contested, this is worth handling with a lawyer who tries Wyoming injury cases. You can find one through the legal directory.
