Louisiana's permit test is 40 questions — you need 32 correct to pass and the fee is $17.50. Study contraflow rules, flood laws, and pass first try.
Louisiana's knowledge test is 40 multiple-choice questions, you need 32 correct (80%) to pass, and the fee is $17.50.
You must be at least 15 to apply. Louisiana's test is longer than most states' and includes questions on laws that don't exist anywhere else — contraflow driving during emergencies, right-of-way at flooded intersections, and hurricane evacuation routes. If you fail, you'll wait 30 days before you can try again, one of the longest retake waits in the country. Here's everything you need to know.
Key Takeaways

The Louisiana Office of Motor Vehicles (OMV) knowledge test is a 40-question multiple-choice exam covering traffic laws, road signs, and safe driving practices. It's required to obtain a Louisiana learner's permit. You must answer at least 32 questions correctly — 80% — to pass.
The test is computer-based and taken at a Louisiana OMV office. Questions cover standard traffic controls and right-of-way rules, but Louisiana's test goes further than most states with questions on emergency driving laws specific to this state.
At 40 questions, Louisiana's test is significantly longer than the national average. The 80% threshold means you can miss no more than 8 questions, so preparing thoroughly isn't optional.
Getting a Louisiana learner's permit follows a defined sequence. Here are the six steps:
Confirm your eligibility. You must be at least 15 years old. Applicants between 15 and 17 need a parent or guardian present to sign the application.
Gather your documents. You'll need proof of identity (birth certificate or passport), your Social Security card, and two proofs of Louisiana residency. Louisiana participates in the REAL ID program, so acceptable documents are strictly defined.
Study the Louisiana Driver's Guide. Every test question comes from this guide. Read it fully, and pay close attention to the sections on emergency driving, hurricane evacuation procedures, and contraflow lane laws — these are Louisiana-specific topics that catch most out-of-state study materials unprepared.
Practice with Louisiana-specific questions. Wheelingo's free practice tests include contraflow driving scenarios, flooded intersection rules, and evacuation route procedures. You can start in under 30 seconds with no account required.
Visit a Louisiana OMV office. Pay the $17.50 fee and take the 40-question knowledge test. You're allowed only one retake within a 30-day period.
Hold your permit for 180 days. If you're under 17, Louisiana requires you to hold a learner's permit for at least 180 days before taking the road test. You'll also need to complete a state-approved driver education course.
Three areas generate the most failures on the Louisiana written test. These are Louisiana-specific — generic study materials won't cover them adequately.
Contraflow is a traffic management system where one or more lanes of a highway are reversed to handle a sudden surge of outbound traffic — typically during hurricane evacuations. Louisiana uses contraflow regularly, and the OMV tests on it directly.
When contraflow is activated, normal lane direction reverses. You'll enter the highway on what's normally the exit ramp, travel in the oncoming lane, and exit where you normally wouldn't. The rules: follow posted signs and law enforcement instructions immediately, maintain consistent speed to avoid rear-end collisions, and do not attempt to turn around in a contraflow zone. Violations during declared emergencies carry enhanced penalties.
Louisiana's geography makes flooded intersections a real hazard, not just a test question. When traffic signals are out due to flooding, the intersection is treated as a four-way stop. You must come to a complete stop, yield to vehicles that arrived before you, and proceed only when it's safe.
The test also covers when not to attempt a flooded road. Louisiana law and common safety guidance follow the "turn around, don't drown" principle — if you can't see the road surface, you don't have enough information to cross safely. Vehicles can be swept off roads in as little as 12 inches of moving water. Knowing this rule cold is essential for both the test and for actual driving in Louisiana.
Louisiana's 30-day retake period after a failed knowledge test is one of the longest in the country, and only one retake is allowed within that 30-day window. This makes first-attempt preparation more important here than in most other states. Understanding the stakes motivates more thorough studying — don't treat this lightly.
Generic practice tests are the biggest problem for Louisiana applicants. Most national DMV prep apps don't include contraflow, flooded intersection rules, or hurricane evacuation procedures. If your study material doesn't cover these topics explicitly, you're underprepared.
Rushing through the road signs section is another pattern. Louisiana's test includes all standard regulatory, warning, and informational signs, and the sheer number of questions (40 total) means signs make up a significant portion. Treat every sign question as a chance to bank a correct answer.
Underestimating the length of the test is a third mistake. Forty questions take longer to complete than a 25-question test, and mental fatigue can cause careless errors on questions you actually know. Practice with full-length tests to build stamina before your appointment.
Passing the knowledge test gets you a learner's permit. If you're under 17, you'll need to hold that permit for at least 180 days before you can test for a license.
During the permit period, you must drive with a licensed adult who's at least 18 and seated in the front seat. Louisiana's graduated license law also restricts your driving hours and passengers during the early license phase that follows your permit.
If you're 17 or older and complete an approved driver education course, you may be eligible for an expedited permit period. Check with your local OMV office for current requirements, as course completion can affect your timeline.
How many questions are on the Louisiana OMV permit test? The test has 40 multiple-choice questions. You need to answer at least 32 correctly (80%) to pass.
What's the passing score for the Louisiana permit test? You need 32 out of 40 correct — an 80% passing score. Missing more than 8 questions means a failing grade.
What happens if I fail the Louisiana permit test? You must wait 30 days before retaking the test. Only one retake is allowed within that 30-day window. Each attempt requires the $17.50 fee.
What is contraflow and why does it appear on the Louisiana test? Contraflow is a lane-reversal system used during hurricane evacuations to move large volumes of outbound traffic. Louisiana uses contraflow more than any other state, so the OMV tests applicants on the rules — including how to enter and exit a contraflow zone and what to do when directed by law enforcement.
How long do I have to hold my permit before taking the road test? If you're under 17, Louisiana requires a minimum 180-day permit-holding period. You'll also need to complete an approved driver education course before becoming eligible for the road test.

You get full access to Louisiana-specific practice questions — including contraflow, flooded intersection rules, and evacuation procedures — with real driving animations the moment you open the app. 94% of users who prep with Wheelingo pass on their first attempt.
Can I take the Louisiana OMV test in another language? Louisiana offers the knowledge test in several languages. Contact your local OMV office to confirm which languages are currently available and whether you need to request an alternative-language test in advance.
The 30-day retake wait makes first-attempt preparation more important in Louisiana than in almost any other state. One failed attempt costs you a month — and that's motivation enough to study properly.
Read the Louisiana Driver's Guide start to finish, not just the road signs section. Focus hard on the state-specific material: contraflow procedures, flooded intersection right-of-way, and hurricane evacuation route laws.
