We wrote these practice questions from the facts in the Oklahoma Driver Manual (Back page 'Updated 11/24/25'; copyright page 2025; PDF modified 2026-07-01, 74 pages, linked from Service Oklahoma's Driver Education page (https://oklahoma.gov/service/all-pages/driver-education.html), read 2026-11-09. Page numbers cited are the printed page numbers, which equal PDF pages. PDF page 26 (traffic signals) has no extractable text and was read from a rendered image. Where the manual is silent or out of date, Oklahoma Statutes Title 47 (complete title from oklegislature.gov, file updated 2025-12-31, including 2025 session laws) and Service Oklahoma's Written Knowledge Test, Learner Permit and Intermediate License pages (read 2026-11-09) are the source. Conflicts found and how they were handled: (1) speed limits table (p. 41) lists 75 mph controlled-access, 80 turnpike, 65 undivided highway; 47 O.S. 11-801 as amended by Laws 2025, c. 197 (eff. Nov. 1, 2025) leaves highway limits to engineering studies, with 75 and 80 only as limits that may be set, so questions use only county roads 55, state parks 35, school zones outside towns 25 and the 75/80 ceilings, cited to the statute; (2) child restraint text (p. 17) is garbled ('at least four 4 years' for the youngest group), so child seat questions follow 47 O.S. 11-1112; (3) funeral processions: the manual (p. 28) says procession vehicles may follow through an intersection regardless of traffic control, while 47 O.S. 11-315 exempts signal- or police-controlled intersections from the no-cutting-in rule, so only the statute rule is tested and common-row-0022 is excluded; (4) penalties for persons under 18 (p. 67: 6 months, 1 year, 2 years or until 21) differ from 47 O.S. 6-107.1 (6 months first, 1 year subsequent), not tested; (5) learner permit age: manual Table 1 (p. 6) and the Learner Permit page say 15 with driver education, while 47 O.S. 6-105(C) (all three 2024 versions read: SB 2038 version) says 15 and a half, not tested; (6) following distance: pp. 34 and 44 give a three-second rule (four in bad weather) but the safety tip on p. 42 says you are too close if you pass the point before four seconds, so following_seconds is left open; (7) speeding penalty 'up to $654 and 30 days' (p. 40) and the impaired-driving suspension list on p. 65 do not match 47 O.S. 11-801(G) and 6-205.1 and are not tested; DUI and refusal revocation questions use 47 O.S. 753 and 6-205.1 (180 days and IDAP); (8) the manual's 15-foot stop from a blind person (p. 28) was not found in Title 47 and is not tested; (9) the $500 crash threshold for suspending an uninsured driver (p. 16) was not found in Title 47 and is not tested; (10) the manual's first insurance bullet on p. 16 repeats 'two or more persons' for $25,000; p. 72 and 47 O.S. 7-324 give $25,000 for one person, which the questions use. edition) and from official sources on road signs.
