PRIMARY SOURCE (used for the large majority of this module): Louisiana Office of Motor Vehicles, 'Class D & E Driver's Guide' official PDF, distributed via expresslane.la.gov/omv/resources/driver-manuals/ and hosted at public.powerdms.com/LADPSC/documents/347039 — fetched and read directly (headlights/wipers, low/high-beam dimming distances, turn-on-red/turn-signal rules, all traffic and pedestrian signal meanings, R.S. 32:143 parking-distance list and curb colors, R.S. 32:76.1 three-foot bicycle passing law, R.S. 32:171 railroad-crossing stop distance, stopped-school-bus rules and divided-highway exceptions, move-over law, funeral procession rules, roundabout rules, right-of-way rules including uncontrolled/T-intersections/pedestrians/visually-impaired pedestrians, the full 3-stage Graduated Driver Licensing program with exact ages/hours/day counts, DWI/BAC penalty tiers and Administrative Per Se suspension schedule including the SR-22/$30,000 financial-responsibility requirement, the offense-based 'grounds for suspension' list used for the points/suspension category in place of a point table, the R.S. 32:295 age-based child-restraint framework (rear-facing to 2, forward-facing 2-4, booster 4-9, seatbelt at 9+, rear seat under 13), the all-driver hands-free phone law and all-driver texting/social-media ban, and the total wireless-device ban for drivers 17 or younger) — verified 2026-08-19. SECONDARY SOURCES (used only where the primary guide's Class D/E manual did not cover the fact, since it is silent on some items covered by the state's separate CDL/points literature): IIHS Louisiana law summary and driving-tests.org/dmv.com aggregator pages, cross-checked, used for: seatbelt law being primary enforcement, covering all occupants age 13+, in effect since 1995, with a first-offense fine around $50; the 0.04% commercial-driver BAC limit; the Problem Driver Pointer System note about out-of-state violations; and the handheld-phone ban specifically inside school zones. Known gaps deliberately NOT invented: Louisiana's general liability-insurance minimum coverage dollar amounts (the primary guide only gives the $30,000 SR-22-substitute figure tied to alcohol-suspension reinstatement, not the baseline financial-responsibility minimums); adult motorcycle helmet and lane-splitting rules (not addressed in the Class D/E guide, which defers to a separate motorcycle manual); exact dollar fines for seatbelt, headphone, and most non-DWI moving violations; and prima facie speed figures for specific unposted road classes beyond the statewide 70 mph default and the towing/school-bus/I-49 exceptions the guide states explicitly. Note: an earlier research pass had flagged the child-restraint age brackets as uncertain between two competing frameworks (2/3/4/8 vs. 2/4/9); the primary OMV guide fetched here resolves this in favor of the 2/4/9 framework used above. EXAM FORMAT ADDED 2026-08-22: this note previously said nothing at all about the mock config, making Louisiana the only state whose exam numbers had no stated justification. They are now confirmed correct — expresslane.la.gov/omv/drivers/personal-driver-s-licenses/permits/ states applicants 'pass a 40 question test with a minimum score of 80%', matching ruleCount 40 / rulePassPct 0.8 (ceil(40 x 0.8) = 32). No separate sign section; signs are mixed into the single pool. Re-verify periodically, as OMV guide content, fees, and statutory thresholds change over time.
