Example cost stack (illustrative, not advice)
The chart below uses round illustrative figures to show the composition of a typical post-DUI cost stack with IID + 3-year SR-22. Every component is flagged as illustrative; your actual case uses the decoder values pinned to your state DMV primary source.
- State DMV reinstatement fee (illustrative)$125
- IID monthly lease (illustrative)$1,020 over 12 mo
- SR-22 premium differential (illustrative monthly)$4,320 over 36 mo
- DUI school course (illustrative one-time)$350
- Substance-abuse evaluation (illustrative)$250
These are illustrative numbers, not state-DMV-verified values. Use the decoder for your specific verdict.
The five components
- State DMV reinstatement fee. Fixed amount set by state statute or DMV schedule. Tabular figure on the decoder. The only component that is a single fixed value.
- Ignition Interlock Device (IID), if required.One-time installation + monthly lease × duration months + removal fee. Paid to an approved provider (LifeSafer / Smart Start / Intoxalock / state-approved alternates). See IID explained.
- SR-22 insurance differential, if required. The filing fee itself is small (commonly under $50, one-time). The cost driver is the premium differential: drivers with an SR-22 trigger pay materially more for liability coverage during the filing period. Differential varies by state, driver history, and carrier. See SR-22 explained.
- DUI / impaired-driving education course, if required. Paid to a state-court-approved provider (Improv, AAA online, American Safety Council, or state alternates). Cost is provider- and length-dependent.
- Substance-abuse evaluation / treatment, if required. Wide variance. Some states require only a one-time evaluation; others require ongoing treatment for the duration of the IID or beyond. Insurance coverage varies; many drivers pay out of pocket.
How the decoder presents the cost stack
The decoder builds a row for each component that applies to your case, marks each row's source URL, and surfaces a range total. Components we have not yet verified to primary or carrier-disclosed source ship asPLACEHOLDER rather than a fabricated number. The reinstatement fee is typically the only component with a single fixed dollar amount; the rest are ranges, and we mark ranges as ranges.
What the decoder will not do
- It will not quote you an SR-22 premium. Carrier-quoting varies by underwriting and is not a procedural data point.
- It will not estimate treatment cost beyond a documented state range. Treatment cost is case-dependent and provider-dependent.
- It will not promise that your final total will fall within the displayed range. We pin the source for each row so you can verify the input we used.
Payment-plan options
Some states allow payment plans on the reinstatement fee or on related fines, particularly for court-debt-driven suspensions. The court-debt-suspension area of the law saw significant 2023–2025 state-level reform; the decoder flags any state where this applies and points to the state-statute primary source. Plans typically come from the state DMV or from the issuing court, not from a third-party payment broker.
