180 days can be the first deadline if a government entity is involved, and 2 years is the usual Idaho deadline for a personal injury lawsuit. If you slipped in Idaho Falls, the smarter move is usually to pursue both first, not guess wrong and let one off the hook.

1. Identify who controlled the ice that day. In Idaho, liability often turns on control and notice. A landlord may be responsible under the lease or property rules, while a snow-removal company may be responsible if it created a dangerous condition or did a careless plow/salt job. In winter around Idaho Falls - parking lots near Sunnyside, Broadway, or the INL commuter routes - black ice can form fast, but that does not automatically excuse either one.

2. Do not let the insurers force you to pick early. Idaho follows comparative fault under Idaho Code § 6-801. Fault can be split among multiple parties, and a defendant usually pays only its share. That means the landlord's insurer may blame the contractor, and the contractor's insurer may blame the landlord. If you pick only one too soon, you can miss the party with real coverage or real fault.

3. Document how this injury worsened your pre-existing condition. You can still recover when a fall aggravates a prior back, knee, or mobility problem. The key is proof: compare your before-and-after function, treatment, imaging, work limits, and mobility changes. If you already used a cane, walker, or wheelchair and now need more help or have more pain, that matters.

4. Check whether any public entity was involved. If the fall happened on property owned by the City of Idaho Falls, Bonneville County, or another public entity, the Idaho Tort Claims Act may require a written notice within 180 days. Private apartment complexes, shopping centers, and contractors do not use that notice rule, but the standard 2-year deadline usually still applies.

5. Preserve the snow-and-ice evidence immediately. Ask for the snow-removal contract, plow logs, salting records, maintenance calls, incident reports, and camera footage. In cold-weather cases, those records often show whether the surface was ignored, over-polished by plowing, or left untreated after refreeze.
