What Idaho DUI Insurance Actually Costs
You received a DUI conviction in Idaho and now face two separate insurance costs: the SR-22 filing fee your carrier charges to notify the Idaho Transportation Department, and the underwriting penalty carriers impose when they see that filing appear on your driving record. Most drivers expect a small filing fee — the actual monthly premium increase runs $150–$280/month depending on which carrier tier will accept you post-conviction.
The SR-22 filing itself adds roughly $15–$25 per month to your premium, paid to the carrier as an administrative fee for maintaining the three-year filing Idaho Code § 18-8005 requires. The real cost driver is the carrier's underwriting response to your DUI flag: you move from standard or preferred tier into non-standard tier, where monthly liability premiums alone start at $130/month before the SR-22 fee layers on top.

$150–$280/mo
Monthly liability premium for Idaho drivers with one DUI conviction requiring SR-22 filing. Non-standard carriers (Dairyland, The General, GAINSCO, Bristol West) occupy the lower half of this range; standard carriers willing to write post-DUI policies (Geico, Progressive, National General) occupy the upper half. Estimates based on available industry data; individual rates vary by driving history, vehicle, coverage selections, and location.

Why the Rate Jumps This High
Idaho carriers treat DUI convictions as high-severity risk events. When your SR-22 filing appears in the Idaho Insurance Verification System, carriers see a state-confirmed violation triggering mandatory filing — this moves your policy from standard underwriting into non-standard tier where loss ratios run 30–50% higher than clean-record drivers.
The premium reflects two separate risk calculations. First, the carrier prices the probability you will file another claim within the three-year SR-22 period — DUI conviction history correlates with claim frequency across the non-standard book. Second, the carrier prices the regulatory cost of maintaining your SR-22 filing: if your policy lapses for non-payment, the carrier must notify Idaho Transportation Department within 30 days, triggering automatic suspension and potential liability exposure for the carrier if you drive uninsured during the lapse window.
Standard-tier carriers (State Farm, Allstate, Liberty Mutual) either decline DUI applicants outright or non-renew existing customers post-conviction. The carriers that remain willing to write — Geico, Progressive, Dairyland, The General, GAINSCO, Bristol West — operate in the non-standard segment where base rates already run 40–60% higher than standard tier before the DUI penalty layers on.
The SR-22 filing fee is $15–$25/month. The carrier's underwriting penalty for your DUI conviction adds $120–$250/month on top of that.
How Carriers Price Your DUI Risk
Carriers calculate your monthly premium by starting with your county's base liability rate (the clean-record premium for minimum state limits: $25,000 bodily injury per person, $50,000 per accident, $15,000 property damage). In Idaho, that clean-record base runs approximately $45–$75/month depending on county and age. The DUI surcharge multiplier ranges from 2.5x to 4x base rate depending on carrier and whether you have prior violations within the preceding five years.
A single DUI conviction with no prior history typically triggers a 2.5x–3x multiplier at non-standard carriers. If your violation history includes prior at-fault accidents, speeding tickets above 15 mph over limit, or a prior DUI within ten years, the multiplier climbs to 3.5x–4x. This explains the $150–$280/month range: a driver in Ada County with one DUI and clean prior history pays roughly $150/month at Dairyland or The General; a driver in the same county with one DUI plus two prior speeding tickets pays $240–$280/month at Geico or Progressive if those carriers accept the application at all.

Ignition Interlock and Premium Impact
Idaho Code § 18-8008 requires ignition interlock device installation for the entire duration of your restricted license period if the court grants you driving privileges during suspension. The IID itself costs $70–$100/month for lease and calibration through approved vendors — this cost is separate from your insurance premium and paid directly to the IID provider.
Some carriers apply a small underwriting credit (5–10% premium reduction) when they verify IID installation because the device mechanically prevents operation above .02 BAC. Geico and Progressive both offer this credit in Idaho; Dairyland and The General do not. The monthly savings rarely exceed $10–$15, and the credit disappears once the IID requirement ends and you transition to unrestricted driving with SR-22 still active.
The combined monthly cost during your restricted license period: $150–$280 insurance premium plus $70–$100 IID lease, totaling $220–$380/month before fuel and maintenance. Once you complete the hard suspension period (30 days minimum for first offense under Idaho Code § 18-8005) and move to unrestricted driving, the IID requirement may drop but the SR-22 filing and carrier surcharge continue for the full three years from conviction date.
Idaho SR-22 Filing Duration
3 years
Idaho requires continuous SR-22 filing for three years following DUI conviction. The period runs from conviction date, not filing date. If your policy lapses at any point during those three years, your carrier notifies Idaho Transportation Department within 30 days and your license suspends immediately until you refile and pay the $25 reinstatement fee.

Which Carriers Write Idaho DUI Policies
Six carriers actively write SR-22 policies for Idaho DUI convictions: Geico, Progressive, Dairyland, The General, GAINSCO, and Bristol West. National General writes some DUI cases but declines applicants with BAC above .15 or prior DUI within seven years. State Farm writes SR-22 for non-DUI triggers (uninsured motorist violations, excessive points) but declines DUI applicants in Idaho.
Dairyland and The General occupy the lowest-cost end of the range ($150–$180/month for minimum liability limits) but require down payments of 25–30% of the six-month premium and offer no payment plan flexibility. Geico and Progressive charge $200–$280/month but allow monthly payment plans with 10–15% down. GAINSCO and Bristol West fall in the middle ($170–$220/month) and are sold exclusively through independent agents, not direct online.
Compare Rates Before You Commit
Premium variation across the six Idaho DUI carriers runs $50–$80/month for identical coverage limits and driver profile. A 35-year-old driver in Boise with one DUI and no prior violations will see quotes from $150/month at The General to $230/month at Progressive for the same $25/$50/$15 liability policy with SR-22 filing. The carrier seeing the lowest risk in your specific violation pattern changes depending on whether you have prior tickets, prior claims, or gaps in prior coverage.
