Cheapest insurance after second DUI: state-by-state rates

A second DUI within your state's lookback window triggers underwriting tier reclassification, not just violation surcharging. Standard carriers apply surcharges to existing rates. High-risk and assigned-risk carriers reprice your entire policy using administrative formulas that ignore competitive market pressures. Most states use 5- to 10-year lookback windows for repeat DUI offenses, meaning your second conviction surfaces in carrier underwriting systems regardless of whether your first offense already aged off your public MVR. California uses 10 years. Florida uses 5 years from conviction date. Texas uses your lifetime conviction count with no statutory ceiling. The rate difference isn't linear. A first DUI typically increases premiums 70-90% through violation surcharging. A second DUI moves you into a different pricing tier entirely, with monthly premiums ranging from $210/mo in states with competitive non-standard markets to $425/mo in states that mandate assigned-risk pool enrollment after two major violations within the lookback period.

Nine states require carriers to assign second DUI offenders to state-run assigned-risk pools: Massachusetts, North Carolina, Maryland, New Jersey, Hawaii, New Hampshire, South Carolina, New Mexico, and West Virginia. In these states, your rate is set by state administrative formula, not carrier competition. Monthly premiums typically range $310-$425/mo for minimum liability coverage. States without mandatory pool assignment allow non-standard carriers to compete for second DUI business. These include Progressive, The General, Acceptance Insurance, Dairyland, and Bristol West. Rates in competitive markets range $180-$290/mo for identical coverage because carriers price violation severity differently. Competitive markets create pricing variation based on time since conviction. A second DUI that occurred 36 months ago prices 25-40% lower than one from 6 months ago in non-pool states. Assigned-risk pool states apply flat administrative pricing regardless of how long ago your conviction occurred, as long as it remains within the state lookback window.

Ohio allows non-standard carrier competition and uses a 5-year lookback for underwriting purposes. Average rates for state minimum liability after a second DUI: $165-$240/mo. Progressive and Dairyland compete actively in this market. Idaho has low base rates and permits competitive high-risk underwriting. Second DUI rates average $150-$210/mo for minimum coverage. The state uses a 5-year lookback and does not mandate SR-22 filing beyond 3 years from license reinstatement. Virginia operates a competitive non-standard market with lower median base rates. Second DUI premiums range $175-$255/mo. The state requires SR-22 but allows carriers to tier violation pricing independently, creating significant rate spread between non-standard insurers. Estimates based on available industry data; individual rates vary by age, vehicle, coverage selections, and specific conviction dates.

Michigan combines no-fault PIP requirements with assigned-risk pool mandates for two or more major violations within 7 years. Monthly premiums for minimum coverage after a second DUI: $380-$520/mo, the highest in the country. Louisiana uses a 10-year lookback for DUI convictions and requires high liability minimums ($15,000/$30,000/$25,000). Second DUI rates average $340-$465/mo even in competitive markets because few non-standard carriers operate in-state. Florida requires both SR-22 filing and elevated liability limits after a second DUI. Average monthly premiums: $290-$410/mo. The state's 5-year lookback and high uninsured motorist rate drive non-standard carrier pricing above national medians. Rates in these states remain elevated even after license reinstatement because carriers apply conviction-count multipliers independently of point-based surcharging, meaning your rate reflects both the violation severity and the repeat-offense tier assignment.

Carriers apply lookback windows at two separate checkpoints: initial underwriting at quote time, and periodic re-underwriting at renewal. If your second DUI falls outside your state's statutory lookback period, standard carriers may still see both convictions during underwriting and apply repeat-offender pricing. California's 10-year lookback means a second DUI conviction from 2015 still triggers high-risk tier assignment in 2025, even though your first conviction from 2012 no longer appears on your public MVR. Carriers access conviction history through state DMV databases that retain records beyond public disclosure timelines. Texas has no statutory lookback ceiling for DUI convictions. Carriers can apply lifetime conviction-count pricing, meaning a second DUI from 15 years ago may still prevent access to standard-market rates if the carrier's underwriting guidelines include lifetime major-violation caps. States with shorter lookback windows create earlier re-entry opportunities. Virginia's 5-year lookback allows drivers with a second DUI from 2019 to re-enter standard markets by 2024 if no additional violations occurred and SR-22 filing obligations have been satisfied.

Progressive writes second DUI policies in 47 states through its standard and non-standard divisions. Rates vary significantly by state tier assignment, ranging $195-$385/mo depending on whether the state permits competitive high-risk underwriting. The General operates in 46 states and specializes in high-risk driver segments. Monthly premiums for second DUI coverage: $210-$340/mo. The carrier applies flat violation-count pricing in assigned-risk states and tiered pricing in competitive markets. Dairyland Auto Insurance writes policies in 45 states and offers violation forgiveness programs that reduce rates after 24-36 months without additional infractions. Second DUI rates start at $175/mo in low-cost states and reach $310/mo in high-cost markets. Acceptance Insurance and Bristol West operate regionally, primarily in the South and Midwest. Both carriers tier second DUI pricing based on time since conviction, with rates decreasing 15-25% at the 12-month and 36-month renewal checkpoints if no new violations surface during re-underwriting.

Request an SR-22 or FR-44 filing from your current carrier within 10 days of conviction if your state requires proof-of-insurance certification. Missing this deadline triggers license suspension in most states, adding administrative reinstatement fees of $150-$350. Get quotes from three non-standard carriers before your current policy renews. Standard carriers typically non-renew after discovering a second DUI during the next underwriting cycle, leaving you 30-60 days to secure replacement coverage before your policy lapses. If your state offers defensive driving or DUI remediation programs that reduce points or satisfy court-ordered requirements, complete them before your first post-conviction renewal. Carriers re-underwrite at renewal using updated MVR data, and program completion can prevent tier reclassification in states that apply violation-count pricing rather than flat administrative rates. Confirm your state's lookback window and conviction date used for underwriting purposes. Some states measure from arrest date, others from conviction date. A 30-day difference can determine whether your second offense falls inside or outside the lookback period at your next renewal, potentially saving $60-$140/mo if the older conviction ages out before re-underwriting occurs.
