Everyone says you have plenty of time, but actually yes - in Idaho, waiting even one week can damage or sometimes wipe out a claim, depending on which claim you have.

If it was a regular crash claim against another driver - for example, a fog-season wreck near Nampa or on an icy overpass - you usually have 2 years to sue for personal injury under Idaho Code § 5-219(4). For vehicle damage only, the limit is usually 3 years under Idaho Code § 5-218. But the legal deadline is not the real problem in week one. Skid marks disappear, Treasure Valley ice melts, and parking-lot or gas-station video may be erased within days.

If the crash happened while you were working, your deadline gets shorter fast. Idaho workers' compensation requires notice to the employer within 60 days under Idaho Code § 72-701. A boss telling you to "use your own insurance" does not extend that. If you were driving between jobs, hauling materials, or moving equipment, delaying notice gives the employer and surety room to argue it was not work-related. In Nampa, that is how a straightforward work-truck or jobsite road claim turns into a coverage fight.

If a government vehicle or road condition is involved - say a city truck, county vehicle, or a dangerous public-road issue - you may have only 180 days to file a tort claim notice under the Idaho Tort Claims Act. Miss that notice deadline and the case can be barred before any lawsuit starts.

A week also matters financially. By tax season, unpaid bills may already be in collections, and health insurers, Medicare, or Medicaid can start asserting reimbursement rights while the crash evidence is getting weaker.
