01 · Why this page exists
A skill that states Missouri law without a citation teaches the model to state Missouri law without a citation — the exact habit this site warns against. It also cannot be maintained: when a breath-testing rule or a statute is amended, nothing in a citation-free skill flags that anything needs updating. So every proposition is pinned to a primary source and a date, or it is marked ⛔ OPEN and withheld.
02 · The rules
- Statutory text comes from the Missouri Revisor (revisor.mo.gov); regulations from the Secretary of State 19 CSR rules PDF — always the version that is operative on the answer date. The Revisor sometimes displays a version that is not yet in force (for example, a § 557.011 version effective January 1, 2028); future text is never merged into a current-law answer.
- Every case is verified through CourtListener for existence and reporter citation before it enters a skill.
- Check appellate history before citing. A missing reporter cite on a Court of Appeals opinion can mean transfer, not a database gap. Worked example: the Ross disposition at WD69900 was superseded on transfer — the citable authority is Ross v. Director of Revenue, 311 S.W.3d 732 (Mo. banc 2010). Citing WD69900 as final means citing a superseded opinion.
- Pin cite to the subsection, never the bare section. § 577.041.3, not § 577.041. § 302.530, not "the hearing statute." § 577.010.6, not "the DWI penalty statute." The subsection is where the errors live.
- Date-stamp the authority file. The breath-testing rules carry amendment dates — 19 CSR 25-30.031/.041/.050/.051/.060 effective March 30, 2020; .021 effective June 30, 2023 — and statutes carry effective dates and pending amendments. mo-dwi-authority.md records each.
- A repealed section is not authority. § 577.026 was repealed effective January 1, 2017; the current PBT exemption is §§ 577.019 and 577.020. Citing a repealed section is a silent error that only a text pull catches.
- Where a proposition cannot be verified, it is marked ⛔ OPEN and does not ship. mo-dwi-authority.md names each open item. The promise is that the skills refuse to invent facts; that promise binds the authority file first.
- The model doesn't decide. The skills give legal information and count dates from the facts you give. You confirm every date with the DOR, the court, or a Missouri attorney before relying on it.
03 · Real corrections this verification pass caught
Pulling the primary text — not reading the draft — surfaced each of these:
- The administrative 15-day hearing deadline is § 302.530, not § 302.525. A draft had the wrong section; the Revisor listing settles it ("within fifteen days of receipt of the notice").
- § 577.023 is procedure only — pleading, proof, and findings of repeat-offender status. The definitions are § 577.001; the classifications are §§ 577.010/.012; the ranges are §§ 558.011/.002. Attributing the offender ladder or a penalty range to § 577.023 is wrong.
- § 577.021 exempts a pre-arrest PBT from §§ 577.019 and 577.020, not from the repealed § 577.026. The old proposition survives in pre-2017 cases only.
- IID eligibility and duration live in Chapter 302 (§§ 302.440/.525/.060), not §§ 577.600–.614 (which create related offenses). A Limited Driving Privilege (§ 302.309) is not the same as a Restricted Driving Privilege (§ 302.010(20), § 302.525).
04 · Corrections from the October 2026 re-check (v2.1.0)
Re-pulling the statutes and the DOR's own rule on 2026-10-01 caught these:
- The license notice is Form 2385 (revised 08-2026). An earlier draft named a different form.
- How a DOR hearing request is counted comes from 12 CSR 10-24.030(1): 15 days after the notice is issued if it was handed to you, 18 days from mailing if the DOR mailed it; a mailed request counts as filed on its postmark date; a deadline on a weekend or state holiday moves to the next business day.
- A refusal has no 15-day court deadline. § 302.574.4 states no filing period. The general statute for appealing a DOR revocation, § 302.311, allows 30 days after notice, and the Missouri Supreme Court applied that limit to refusal revocations in Romans v. Director of Revenue, 783 S.W.2d 894 (Mo. banc 1990), construing the predecessor statute. A late petition can't be heard. The 15-day temporary permit (§ 302.574.1) is how long you can drive, not a filing deadline.
- The five-year window applies only to the "prior offender" tier (§ 577.001(20)). The higher tiers' definitions contain no time window.
- § 577.010 was amended effective August 28, 2026, and the skills now use the current text. § 302.441 covers only an interlock employment exemption, so it is no longer cited for interlock requirements generally.
05 · What is watched or still open
mo-dwi-authority.md marks every unverified or contingent item. Currently open, among others: whether a past SIS counts as a prior offense; whether an SIS protects a commercial driver's license; the current terms of § 302.440 (amended August 28, 2026, not yet re-verified); and the DOR mailing address (the rule and the DOR website list different ones). No fixed SATOP hour count exists in statute — it is assessment-driven, so none is asserted. Cases carrying only a docket number are confirmed to a reporter citation through CourtListener before they are relied on.
Nothing on this page is legal advice, and these skills are not a lawyer. They organize, explain, and count deadlines from the dates you give. Treat every AI answer as a starting point, not the final word — and confirm every date before you rely on it.
