In Colorado, most vehicle-injury claims expire after 3 years; in Wyoming, you usually have 4 years. For a private crash claim in Casper, that means you may still have time if the wreck happened less than 4 years ago.

Wyoming's general deadline for personal-injury claims is 4 years under Wyo. Stat. § 1-3-105(a)(iv)(C). That covers many crashes involving another driver, including a contractor vehicle, landscaping truck, or trailer collision.

The major exception is a road-defect or government case. If the crash involved a collapsed roadway, missing guardrail, or poor maintenance by the City of Casper, Natrona County, or WYDOT, Wyoming's Governmental Claims Act usually requires a formal written claim within 2 years. If that deadline passed, a sinkhole or road-condition claim may already be barred even though a normal crash claim would still be open.

If your case is still timely, Wyoming law allows recovery for long-term losses, not just the first hospital bills. That can include:

• Future medical treatment
• Medicare-covered accident care that Medicare paid conditionally
• Reduced earning capacity, even after partial retirement
• Permanent impairment evidence from your doctors
• Pain, mobility loss, and household help you now need

If you already signed a settlement release months or years ago, that usually ends the claim completely. A later surgery, worsening back pain, or a new disability finding from Social Security does not reopen a settled liability case.

For someone in Casper on Medicare and fixed income, timing matters because unpaid accident bills, Medicare reimbursement claims, and collection pressure often surface during tax season. If no lawsuit was filed and no settlement was signed, the key question is simple: Was it a private-party crash within 4 years, or a government-related claim that needed notice within 2 years?
