Why Full Coverage SR-22 Quotes Vary $2,800 Per Year in Idaho
You called three carriers after your Idaho DUI conviction. One quoted you $185/month for SR-22 liability-only. Another quoted $310/month for full coverage. A third quoted $420/month for full coverage with the same limits. You're trying to figure out which quote is real and which carrier is padding the SR-22 fee, but the actual difference has nothing to do with the SR-22 filing itself — it's how each carrier prices your conviction date against their underwriting tier.
Idaho requires SR-22 filing for 3 years after a DUI conviction, measured from the conviction date. The $25 SR-22 filing fee is identical across all carriers licensed in Idaho. The premium difference you're seeing is collision and comprehensive coverage priced against a DUI conviction that's either 6 months old or 2 years old, and carriers price that risk gap differently depending on whether they write standard, non-standard, or high-risk policies. The cheapest quote today may not stay cheapest across your 3-year filing window.

$25
Every carrier licensed in Idaho charges the same $25 SR-22 filing fee to submit your proof-of-insurance certificate to the Idaho Transportation Department. The premium variation you're comparing has nothing to do with this fee — it reflects how carriers price collision and comprehensive coverage for DUI-convicted drivers.

What Full Coverage Actually Adds to Your SR-22 Premium
Full coverage is liability plus collision plus comprehensive. Idaho's minimum liability requirement is $25,000 bodily injury per person, $50,000 per accident, and $15,000 property damage. That liability-only SR-22 quote you received covers those minimums and nothing else. Full coverage adds collision (pays for damage to your vehicle in an accident regardless of fault) and comprehensive (pays for theft, vandalism, weather damage, and non-collision events).
After a DUI conviction, carriers price collision coverage as if you're statistically more likely to file a claim. Standard-tier carriers like State Farm and Allstate typically add $95–$140/month for collision and comprehensive on top of liability premiums. Non-standard carriers like Bristol West and Dairyland add $60–$95/month for the same collision and comprehensive limits because they price DUI risk into their base liability premium already, making the collision add-on proportionally smaller.
If your vehicle is financed or leased, your lender requires full coverage regardless of cost. If you own your vehicle outright and its market value is under $4,000, the collision premium may exceed what you'd recover from a total-loss claim, making liability-only the financially rational choice. If your vehicle is worth $8,000 or more and you cannot afford to replace it out-of-pocket, full coverage justifies its cost even at post-DUI rates.
The carrier quoting you the lowest rate today may not be the cheapest carrier 18 months into your SR-22 filing period — DUI surcharges decay on different schedules by carrier tier.
How Conviction Recency Changes Your Full Coverage Quote
Standard-tier carriers like State Farm, Geico, and Progressive price DUI convictions with a surcharge that decays gradually over 3 to 5 years. At 6 months post-conviction, expect full coverage premiums of $380–$490/month. At 24 months post-conviction, the same carrier may quote $260–$340/month for identical limits. The surcharge drops by roughly 15–25% per year as the conviction ages, but it never fully disappears until the conviction falls outside the carrier's lookback window — typically 5 years in Idaho.
Non-standard carriers like Bristol West, Dairyland, GAINSCO, and The General price DUI risk into their base tier, so conviction recency matters less. A 6-month-old DUI may quote $290–$360/month for full coverage; a 24-month-old DUI may quote $260–$310/month. The spread is narrower because these carriers assume elevated risk for all drivers in their book. If your conviction is recent, non-standard carriers often quote 20–30% lower than standard-tier carriers. If your conviction is 30+ months old and your driving record has been clean since, standard-tier carriers may re-quote lower than non-standard.

Comparing Quotes Across Your 3-Year SR-22 Window
Idaho requires continuous SR-22 filing for 3 years from your conviction date. If your SR-22 lapses for any reason — you cancel your policy, you miss a payment, your carrier drops you — the Idaho Transportation Department suspends your license immediately and restarts your 3-year filing clock from the date you refile. This means the premium you're comparing today is not just one year's cost; it's the total cost of maintaining coverage across 36 months.
A carrier quoting you $310/month today may increase that premium to $340/month at your first renewal if your conviction stays recent in their underwriting model. Another carrier quoting $290/month today may hold that rate flat or drop it to $270/month after 12 months if their surcharge decay schedule is faster. You cannot predict renewal pricing with certainty, but you can ask each carrier whether their DUI surcharge decreases at renewal and on what schedule.
The cheapest 3-year total cost comes from the carrier whose surcharge decays fastest relative to your conviction date, not the carrier quoting the lowest month-one premium. If you're 8 months post-conviction and comparing a $290/month non-standard quote against a $380/month standard-tier quote, the standard-tier quote may cost less over 36 months if its surcharge drops by 20% per year while the non-standard carrier holds rates flat. Run the math on total cost, not monthly cost.
Idaho SR-22 Filing Period
3 years
Idaho Code § 18-8005 requires SR-22 filing for 3 years after a DUI conviction, measured from the conviction date. If your filing lapses at any point during those 3 years, the Idaho Transportation Department suspends your license and restarts the 3-year clock from the date you refile, meaning a single lapse can extend your total filing obligation to 4 or 5 years.

Which Idaho Carriers Write Full Coverage SR-22 After DUI
Not all carriers licensed in Idaho write SR-22 policies, and fewer write full coverage for DUI-convicted drivers. Standard-tier carriers like State Farm, Geico, and Progressive write SR-22 filings in Idaho and offer full coverage, but they price DUI risk with the highest surcharges — expect quotes of $360–$490/month for full coverage in the first 12 months post-conviction. These carriers are often cheapest for drivers whose DUI conviction is 30+ months old and whose record has been clean since.
Non-standard carriers like Bristol West, Dairyland, GAINSCO, The General, and National General specialize in high-risk drivers and write SR-22 policies with full coverage in Idaho. Expect quotes of $260–$360/month for drivers with recent DUI convictions. These carriers typically do not reduce premiums as aggressively as standard-tier carriers when your conviction ages, but they start lower and hold steadier across the 3-year window. If your DUI is recent and your budget is tight, start with non-standard carriers.
Get Quotes That Reflect Your Actual SR-22 Timeline
You need quotes from at least three carriers writing SR-22 policies in Idaho, and you need to compare them across your full 3-year filing period, not just the first month's premium. Start with non-standard carriers if your conviction is less than 18 months old. Add standard-tier carriers to your comparison if your conviction is 24+ months old or if you've completed your restricted license period without violations. Ask each carrier whether their DUI surcharge decreases at renewal and request a 3-year total-cost estimate if they offer one. The carrier quoting the lowest month-one rate may not be the cheapest option by year two, and switching carriers mid-filing risks a coverage gap that restarts your SR-22 clock. Compare the full window before you commit.
