When the Clock Starts
In Wyoming, the limitations period for car accident lawsuits generally begins on the date of the accident. Wyoming recognizes a discovery rule for this claim type: Wyoming courts apply a discovery rule under which a tort cause of action accrues when the plaintiff knows or has reason to know of the existence of the injury and its cause.

Exceptions That Can Extend the Deadline
- Minors: the clock is generally paused while the injured person is under 18.
- Fraudulent concealment: if the defendant actively hid the wrongdoing, the deadline may be extended until it was or should have been uncovered.
- Defendant leaves the state: absence can pause the clock in many circumstances.
- Government-claim trap: To sue a Wyoming governmental entity, an itemized written claim must be presented within two years of the accident under the Wyoming Governmental Claims Act (Wyo. Stat. § 1-39-113), and recovery is subject to the damage limits in Wyo. Stat. § 1-39-118.
Wyoming's 4-year catch-all limit in § 1-3-105(a)(iv)(C) is among the longest in the nation, and the Wyoming Constitution (Art. 10, § 4) bars any statutory cap on damages in ordinary personal-injury or wrongful-death suits.

What to Do Before the Deadline Runs
- Pin down your accrual date — the day the clock started — and calendar the deadline conservatively.
- Preserve evidence now: photos, records, witness contacts, bills. Evidence decays faster than deadlines.
- Send preservation/notice letters where required (especially for Wyoming government defendants).
- If the deadline is inside 6 months, treat it as urgent — filing suit is the only reliable way to stop the clock.

Frequently Asked Questions
How long do I have to file a car accident lawsuit in Wyoming?
You have 4 years from the date of the accident, under Wyo. Stat. § 1-3-105(a)(iv)(C).
Can I still sue after 4 years in Wyoming?
Usually no — courts dismiss claims filed after the statute of limitations expires. Narrow exceptions (the discovery rule, tolling for minors, fraudulent concealment) can extend the deadline; whether one applies depends on your facts.
Does the discovery rule apply to car accident lawsuits in Wyoming?
Yes. Wyoming courts apply a discovery rule under which a tort cause of action accrues when the plaintiff knows or has reason to know of the existence of the injury and its cause.
What if the victim was a minor?
Wyoming generally pauses ("tolls") the deadline while the injured person is under 18, giving them time to file after reaching adulthood. Special limits can still apply, so check the statute.
Is the deadline different for claims against the government?
To sue a Wyoming governmental entity, an itemized written claim must be presented within two years of the accident under the Wyoming Governmental Claims Act (Wyo. Stat. § 1-39-113), and recovery is subject to the damage limits in Wyo. Stat. § 1-39-118.
