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 for bodily injury, and $15,000 for property damage. Drivers convicted of DUI, caught driving without insurance, or involved in at-fault accidents without coverage must file SR-22 certification with the Idaho Transportation Department. The SR-22 filing proves continuous coverage for the required period, and any lapse restarts the clock. For high-risk drivers, carrying only state minimums leaves significant financial exposure in serious accidents.
How Much Does Car Insurance Cost in Idaho?
High-risk auto insurance rates in Idaho vary widely based on violation type, driver age, location, and coverage level. A first-time DUI typically increases premiums by 80–150%, while drivers with multiple violations or accidents may see increases of 200–300% or require non-standard carriers. Urban areas like Boise and Idaho Falls typically show higher rates than rural counties, but carrier availability matters more than location for high-risk drivers.
