Minimum Coverage Requirements in Idaho
Idaho requires minimum liability coverage of 25/50/15: $25,000 per person for bodily injury, $50,000 per accident, and $15,000 for property damage. Drivers with DUI convictions, license suspensions for violations, at-fault accidents while uninsured, or repeat violations typically must file SR-22 proof of insurance with the Idaho Transportation Department for three years. Once your SR-22 requirement ends, the Idaho Transportation Department stops monitoring your insurance, but the underlying violation remains on your driving record for up to 7 years affecting rates.
How Much Does Car Insurance Cost in Idaho?
Post-SR22 drivers in Idaho typically pay $180–$320/mo for full coverage in the first 12 months after their requirement ends, depending on the underlying violation, vehicle, age, and location. Rates drop significantly in years 2–3 as the violation ages and you demonstrate continuous coverage. By year 5, drivers with no new incidents often return to near-standard rates of $90–$140/mo.
What Affects Your Rate
- Type of violation: DUI penalties persist longer than lapse-related SR-22 in Idaho underwriting models
- Time since SR-22 ended: rates improve 30–50% in year one, another 20–30% in year two
- Continuous coverage: any gap after SR-22 ends signals risk and delays access to standard rates
- Location: Boise and Coeur d'Alene have more carrier competition than rural counties
- Vehicle type: older vehicles with liability-only reduce premium but limit carrier options
- Credit-based insurance score: Idaho allows credit as a rating factor, which can help or hurt post-SR22 shoppers
