Take a free, untimed Louisiana DMV practice test in the real exam format: 40 questions, 32 correct to pass. Fresh random questions every attempt.
The Louisiana knowledge test is a single 40-question exam covering road signs and the rules of the road together. You need 32 correct (80%) to pass.
Answer: The vehicle on the left yields to the vehicle on the right
When two vehicles arrive at the same time at a controlled or 4-way-stop intersection, the driver on the left must yield to the vehicle on the right.
Right-of-Way
Answer: When it is clear to do so, yielding to emergency vehicles and other roadway users as required
A steady green light means you may go through if clear, but you must still yield to emergency vehicles and other roadway users as required by law.
Signals
Answer: Louisiana does not use a numeric point/demerit system — suspension is triggered by specific offenses instead
Unlike many states, Louisiana does not use a numeric point system. Instead, specific offenses (DWI, test refusal, insurance lapse, etc.) directly trigger suspension.
License Suspension Triggers
Answer: Within 18 inches
Louisiana law requires parallel-parked vehicles to have their right wheels within 18 inches of the curb.
Parking Rules
Answer: Until at least age 2
Louisiana requires rear-facing seating in a federally approved car seat from birth until at least age 2.
Child Passenger Safety
Answer: Vehicles on the through road
At a T-intersection, you must yield to vehicles on the through road.
Right-of-Way
Answer: Other drivers making a right turn on red from the other side of the intersection
With a green arrow, oncoming and crossing traffic should yield to you, but you should still watch for others turning right on red from the opposite side.
Signals
Answer: Failure to stop for a school bus loading or unloading children
Failure to stop for a school bus loading or unloading children is one of the specific offenses listed as grounds for suspension.

Questions and exam format researched against Louisiana's official driver handbook and state sources. Last verified 22 August 2026.
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.
