Oklahoma Driver Manual (Service Oklahoma), official PDF fetched directly from https://oklahoma.gov/content/dam/service-oklahoma/Documents/OklahomaDriverManual.pdf — linked from Service Oklahoma's "Oklahoma Written Knowledge Test" page at https://oklahoma.gov/service/popular-services/written-test.html, with the driver study hub at https://oklahoma.gov/service/all-pages/driver-study-hub.html as the study-materials landing page. Researched and verified 2026-08-19; citation gap closed 2026-08-20 by re-fetching both the written-test page and the 35MB manual PDF (downloaded via curl — it exceeds the fetch tool's 10MB cap — and text-extracted with pdftotext, not a scan). Edition CONFIRMED from the extracted text: "Copyright 2025 Service Oklahoma, State of Oklahoma" with a trailing "Updated 11/24/25" stamp. Exam format is fully confirmed, not estimated: the Service Oklahoma written-test page states verbatim "To pass, you must correctly answer 15 out of 20 questions" (75%), as one combined pool with signs included rather than a separate sign-recognition section, hence signCount: 0/signPassCount: 0 with ruleCount: 20 and rulePassPct: 0.75. Note the manual PDF itself does NOT restate that count — the written-test page is the sole official source for it, so re-check that page specifically if the figure is ever disputed. The same page also links an older https://oklahoma.gov/content/dam/service-oklahoma/Documents/OklahomaDriverManual2023.pdf for the in-person test path; the undated OklahomaDriverManual.pdf above is the newer of the two and is what this module was verified against. Service Oklahoma is the current (2022+) state licensing authority — it replaced the Department of Public Safety (DPS) for driver licensing functions, which is why this module's dmvName references Service Oklahoma rather than DPS. Known gaps deliberately NOT invented or asserted, per source guidance: no general statewide ban on adult drivers making handheld phone calls (only commercial/public-transit drivers are confirmed banned from handheld calls); no textual legal definition of reckless driving beyond its confirmed 4-point value; no 'headlights required when wipers are running' rule (unconfirmed/likely absent from OK law, unlike some other states); and no universal 'must log N supervised hours' figure for the standard GDL track — the only confirmed hour figures (30 classroom / 55 behind-the-wheel) apply specifically to the Parent-Taught Driver Education curriculum, not a general mandate for all permit holders. Re-verify periodically, as manual content, fees, and thresholds change over time.
