Idaho Auto Insurance
Rates & Coverage Report
Real policy data from our Idaho clients — including Idaho’s unique broad form coverage option. Compare rates across 8 counties from the Panhandle to eastern Idaho, and understand what drives pricing differences across the state.
Idaho Summary
This Idaho report is built from 20 sold policies across 8 Idaho counties during 2024–2025 — from the northern Panhandle (Bonner, Boundary, Kootenai) to eastern Idaho (Bonneville, Jefferson) and the Treasure Valley (Ada, Canyon). Idaho is one of our more geographically diverse single-state datasets, spanning very different market environments.
The average monthly premium across Idaho is $78.50 — one of the lowest averages across all states we serve. This reflects Idaho’s generally favorable insurance environment: lower population density outside the Treasure Valley, fewer fraud claims than coastal states, and a high proportion of broad form and non-owners policies in our dataset which are lower-cost products by nature.
Idaho is one of only a handful of states that offers broad form auto insurance — a named-driver policy that covers you personally regardless of which vehicle you drive, rather than insuring a specific vehicle. Nearly half our Idaho policies (9 of 20) are broad form, which is unique to this state and worth understanding if you’re shopping for Idaho coverage.
Drivers shopping for coverage in Idaho often want to understand the state’s liability requirements, how premiums are calculated, and what factors influence rates such as driving history, ZIP code, vehicle type, and prior claims. For a deeper breakdown of state laws, coverage choices, and pricing factors, review our Idaho auto insurance guide.
🔑 What Is Idaho Broad Form Auto Insurance?
Broad form (also called “named operator”) insurance covers a specific driver — not a specific vehicle — for liability. It’s legal in Idaho and a few other states, and it’s often significantly cheaper than a standard auto policy because it only covers the named driver, not all household members. It satisfies Idaho’s financial responsibility law and is popular among single drivers who own older vehicles or want the most affordable liability compliance. It does not provide collision or comprehensive coverage. We write broad form through Dairyland, one of the top carriers for this product in Idaho.
Idaho drivers often compare liability only, full coverage, and deductible options before choosing a policy. If you want a more complete explanation of Idaho coverage rules, optional protections, and how different policy choices affect pricing, see our Idaho auto insurance guide.
Carrier Distribution
Carriers from our Idaho dataset. Dairyland’s strong presence is directly tied to broad form and non-owners specialty products.
| Insurance Company | Policies | Share |

| ASI | 1 | 5.0% |
| Bristol West | 1 | 5.0% |
Some Idaho drivers relocate, commute, or compare coverage with nearby states in the Northwest and northern Rockies. If you are moving west or comparing regional market differences, it may help to review Oregon insurance. Drivers comparing coverage farther east and north may also want to explore Montana insurance to see how requirements and pricing can differ across neighboring states.
Idaho Snapshot
Key rate benchmarks from our 2024–2025 Idaho policy data.
A 1,335% spread from floor to ceiling — but the $11.75 floor is a renters policy in Ada County, not auto. Auto-only rates run from roughly $34 to $168/month in this dataset. Idaho’s broad form policies, which make up nearly half our book, are among the most affordable products we write anywhere.
Real premiums from sold policies — not estimates. The low average reflects Idaho’s affordable market and our specialty-heavy mix. Standard auto full coverage in Idaho will run higher than what these averages suggest.
- Highest average county premium: Bonneville County ($145.41/mo, Idaho Falls area) — eastern Idaho’s largest market, 4 policies with consistent liability-heavy profiles.
- Lowest average county premium: Ada County ($11.75/mo, Boise area) — single renters policy. Auto rates in Ada/Canyon (Treasure Valley) are higher than this suggests.
- Panhandle counties are affordable: Bonner ($39.72) and Boundary ($38.80) reflect rural northern Idaho — low density, lower risk, mostly broad form policies.
- Jefferson County spread: $44.05 to $99.69 across 3 policies — reflects different coverage levels (broad form vs. standard liability).
- Top county by policy volume: Three-way tie — Bonner, Bonneville, and Kootenai at 4 policies each.
Drivers with tickets, accidents, lapses in coverage, suspended licenses, or other underwriting challenges sometimes need a company that works more comfortably in the non standard market. One option some shoppers review is Dairyland Insurance, which may be relevant for Idaho drivers looking at alternative coverage options.

Idaho Insurance Context
Key things to know about Idaho’s insurance requirements, broad form, and regional pricing dynamics.
Idaho Minimum Liability Requirements
Idaho requires 25/50/15 liability minimums: $25,000 per person bodily injury, $50,000 per accident, and $15,000 for property damage. Idaho does not require PIP or uninsured motorist coverage, which helps keep minimum compliance premiums lower than states with broader mandatory coverage.
Broad Form vs. Standard Auto vs. Non-Owners
- Broad Form: Covers a named driver on any non-owned vehicle. Cheapest liability compliance. Ideal for drivers without a regularly available vehicle or those between cars. Does not cover physical damage to the vehicle.
- Non-Owners: Similar to broad form — liability coverage for the named driver on borrowed/rented vehicles. Slightly different structure but serves a similar purpose. Also used for SR-22 compliance without owning a car.
- Standard Liability: Covers a specific vehicle for liability. Required if you own a registered vehicle in Idaho. More expensive than broad form but necessary for owned vehicles.
SR-22 in Idaho
Idaho requires SR-22 certification for DUI, serious violations, or license suspension situations. We file SR-22 electronically through Dairyland and Progressive, same-day in most cases. Broad form and non-owners SR-22 policies are available for drivers who don’t own a vehicle but need compliance proof.
North Idaho vs. Treasure Valley vs. Eastern Idaho
Idaho’s three major regions have meaningfully different rate environments. The Panhandle (Kootenai, Bonner, Boundary) is rural and lower-risk, with some of the state’s most affordable rates. The Treasure Valley (Ada, Canyon counties — Boise, Nampa, Meridian) is Idaho’s most densely populated area and sees higher rates due to traffic volume and claim frequency. Eastern Idaho (Bonneville, Jefferson, Bingham counties) sits in the middle — mid-sized cities like Idaho Falls with lower density than Boise but more activity than the Panhandle.
