Shared fault
Wyo. Stat. § 1-1-109(b)
Contributory fault shall not bar a recovery in an action by any claimant or the claimant’s legal representative to recover damages for wrongful death or injury to person or property, if the contributory fault of the claimant is not more than fifty percent (50%) of the total fault of all actors.

This is modified comparative fault, often called the 51% bar. An injured person who is 50% or less at fault can recover damages reduced by their share; one who is more at fault than the parties the statute compares them to cannot recover.
Auto insurance requirements
Wyo. Stat. § 31-9-102 sets financial responsibility at “twenty-five thousand dollars ($25,000.00) because of bodily injury to or death of one (1) person in any one (1) accident, and subject to the limit for one (1) person, in the amount of fifty thousand dollars ($50,000.00) because of bodily injury to or death of two (2) or more persons,” with a property damage amount in the same section.[4] Wyoming is not one of the no-fault states.[5]
