What is the Louisiana CDL knowledge test?

The Louisiana CDL knowledge examination tests your understanding of commercial operating regulations. You must pass to get a Commercial Learner's Permit (CLP) which you need before taking the skills test for a full CDL. The test covers commercial motor vehicle operation, safety regulations, traffic laws and safe operating procedures.

You'll take it on a computer at Office of Motor Vehicles (OMV) locations throughout Louisiana. The questions include federal regulations and Louisiana specific rules so you can safely operate commercial motor vehicles in Louisiana and out of state. For more information, visit the Louisiana OMV website.

Who needs to take the CDL knowledge test in Louisiana?

You need this test if you're getting your first CLP or adding a new endorsement. You'll also need it if you're upgrading your CDL class (like moving from Class B to Class A) or reinstating an expired CDL (over one year). You'll also need it if you're transferring a CDL from another state with new endorsements.

All applicants must take the general knowledge test plus additional tests for specific endorsements like Passenger (P), School Bus (S), Tank Vehicles (N), Hazmat (H), or Doubles/Triples (T). Each endorsement has its own test for that specific vehicle or cargo type.

Why is the CDL knowledge test important?

The knowledge test ensures commercial drivers have the knowledge to safely operate commercial motor vehicles. It verifies your understanding of regulations, safety practices, technical aspects and emergency procedures. This verification helps maintain safety standards and reduces accident risks on public roads.

Remember commercial motor vehicles can cause significant damage in accidents because of their size and weight. So proper knowledge and training is essential before operating these vehicles. This is your first step in proving you're ready for commercial operating responsibilities.

How does the Louisiana test match federal requirements?

The test follows Federal Motor Carrier Safety Administration standards along with Louisiana specific regulations. This combination ensures national consistency in commercial driver qualifications while addressing state specific requirements.

Be aware that topics covered include general operating skills, air brake operations, combination vehicles and specific endorsements. As a CDL applicant your Louisiana CDL will be recognized throughout the United States so you can operate commercial motor vehicles across state lines if you meet age and other requirements for interstate commerce.

How many questions are on the Louisiana CDL knowledge test?

  • General Knowledge test: 50 questions
  • Air Brakes: 25 questions
  • Combination Vehicles: 20 questions
  • Passenger Endorsement: 20 questions
  • School Bus Endorsement: 20 questions
  • Hazmat Endorsement: 30 questions

What score do I need to pass?

You must answer 80% of questions correctly on each examination:

  • General Knowledge: 40 out of 50 questions correct
  • Air Brakes: 20 out of 25 correct
  • Combination Vehicles: 16 out of 20 correct

Each examination is scored separately. So if you fail one but pass others you'll only need to retake the one you failed.

What languages can I take the test in?

The test is only offered in English. Federal regulations require commercial drivers to read and speak English well enough to understand traffic signs, communicate with officials, complete records and understand shipping documents.

This English requirement ensures all commercial drivers can safely navigate roadways, communicate with law enforcement and emergency services and properly handle documentation. There are no exceptions to this language requirement in Louisiana CDL examinations.

Can I use study aids during the test?

You cannot use notes, electronic devices, reference materials or calculators during the examination. Testing areas are monitored and using prohibited materials will result in examination failure. All personal items must be stored in a designated area during testing. This includes:

  • Cell phones and electronic devices
  • Notes or cheat sheets
  • Commercial Driver License manuals
  • Reference materials of any kind
  • Calculators (unless specifically authorized for certain questions)

Using prohibited materials during testing could result in immediate disqualification and may affect your ability to retest in the future.

How long do I have to complete the test?

There's no time limit to complete the examinations. Most applicants finish the general knowledge test in 60-90 minutes. Endorsement tests typically take 30-45 minutes each. Plan your visit accordingly if taking multiple tests in one day. The OMV provides sufficient time to complete the tests without rushing. If you have documented learning disabilities or other special needs, accommodations may be available with proper documentation.

What types of knowledge tests are available?

The tests available are:

  • General Knowledge (required for all CDLs)
  • Air Brakes (for vehicles with air brakes)

  • Passenger (P) Endorsement (for buses)
  • School Bus (S) Endorsement
  • Doubles/Triples (T) Endorsement
  • Tank Vehicle (N) Endorsement
  • Hazmat (H) Endorsement

Each test covers specific knowledge for that class of vehicle or type of operation. As a CDL applicant you only need to take the tests for the type of commercial operating you plan to do.

How do I prepare for the Louisiana CDL knowledge test?

  • Study all relevant sections of the Louisiana CDL Manual for your license class and endorsements
  • Take our free practice tests online to test your knowledge
  • Create a study schedule over several weeks rather than cramming at the last minute
  • Make flashcards for difficult concepts and technical terms to help memorization
  • Focus extra time on air brakes and hazmat regulations
  • Review the pre-trip inspection procedures thoroughly as they are a major part
  • Pay attention to Louisiana specific regulations and prerequisites that may be different from other states
  • Study vehicle systems and components until you understand how they work
  • Familiarize yourself with all required documentation and procedures before your test day

The key to success is consistent study over time rather than last-minute cramming. Many applicants underestimate the technical knowledge required, especially for specialized endorsements.

Are practice tests available?

Yes! Our free practice tests are available online. These practice tests will help you:

  • Identify knowledge gaps in your understanding of CDL material
  • Build confidence through repeated practice in a low pressure environment
  • Simulate the actual test environment and format to reduce test anxiety
  • Track your progress as you improve your scores
  • Understand explanations for both correct and incorrect answers
  • Get familiar with the types of questions asked on the actual test

Practice tests cover all CDL test categories and are updated regularly to reflect current testing standards. Using practice tests has been shown to significantly increase first-attempt pass rates.

How do I pass the CDL knowledge test?

  • Start studying at least 2-3 weeks before your test date to avoid last minute cramming
  • Understand concepts rather than just memorizing answers for better long term retention
  • Take practice tests to identify and focus on weak areas in your knowledge
  • Get enough rest the night before your test to be mentally clear
  • Eat a good meal before testing to stay focused throughout the test
  • Read questions completely before selecting answers to avoid careless mistakes
  • Look for keywords like "always", "never" or "except" that can change the meaning of a question
  • Choose safety oriented answers when unsure as safety is emphasized in CDL regulations
  • Review all answers before submitting if the testing system allows
  • Stay calm and focused throughout the test

Sample question: When managing your space on the road you should:

  • Only worry about space in front of your vehicle
  • Keep a space cushion on all sides of your vehicle
  • Focus mainly on space to the sides in city driving
  • Reduce following distance in good weather conditions

Answer: B. Keep a space cushion on all sides of your vehicle

How are practice tests like the actual test?

Practice tests cover the same topics and format as the actual test, though specific questions will differ. Good practice tests mirror the style, difficulty and content of the actual Louisiana CDL knowledge test. These practice tests help you become familiar with:

  • Question formats and wording styles you'll see on the actual test
  • Content depth and breadth covered in the examination
  • Time management skills needed during testing
  • Critical thinking skills required for test success

Understanding concepts is more important than memorizing specific answers, as the actual test draws from a large question bank and each examination is unique. The Louisiana OMV regularly updates its question bank, so focus on understanding the principles behind each topic rather than trying to memorize exact questions and answers.

Where do I take the CDL test?

The CDL test is administered at Louisiana Office of Motor Vehicles (OMV) locations that offer commercial licensing services. Not all OMV offices offer CDL testing, so check the Louisiana OMV website or call ahead to confirm. Testing locations have special equipment and staff for CDL testing. Major testing locations are in Baton Rouge, New Orleans, Shreveport, Lafayette and other cities throughout Louisiana. Call the location for hours and any special instructions before you go.

Do I need an appointment?

Appointments are highly recommended for CDL testing in Louisiana. Contact your local OMV office or visit the Louisiana OMV online services to find out their scheduling process. Some locations may accept walk-ins for CDL testing but wait times can be long. Be aware that without an appointment you may not be able to test that day if capacity is reached. Scheduling an appointment ensures you'll be tested at your preferred time and location. Plan ahead especially during peak periods.

Can I take the test online?

All CDL tests must be taken in person at OMV offices. This in-person requirement is for security, identity verification and examination integrity. Remember this is a federal requirement that applies to all states not just Louisiana. In-person testing prevents cheating and ensures the person receiving the CDL is the one who demonstrated the knowledge. Online testing is not available for any CDL tests due to security reasons.

What do I need to bring to the test?

  • Valid picture driver's license as primary ID
  • Completed Supplemental Application Form (DPSMV 2211) with all sections filled out
  • Current DOT Medical Certificate (Form MCSA-5876) showing you're physically qualified
  • Proof of liability insurance on personally owned vehicles
  • Proof of your Social Security number for ID purposes
  • Proof of Louisiana residency showing your current address
  • Payment for applicable fees
  • For Hazardous Materials endorsements: additional ID documents for the security threat assessment
  • Reading glasses if you need them
  • Appointment confirmation if you scheduled one

Be aware that all documents must be original or certified copies. Photocopies are not accepted. For complete, up-to-date documentation requirements, visit the Louisiana OMV CDL page.

How early should I arrive?

Get there 15-20 minutes early to allow time for:

  • Document verification
  • Application processing
  • Fee payment
  • Getting settled before the test

If you're late you may have to reschedule and lose your appointment. First-time applicants should arrive 30 minutes early to allow extra time for initial paperwork processing. Traffic and parking at OMV offices can be unpredictable so plan accordingly with extra time. Being early reduces stress and helps you perform better on the test.

What if I pass?

After passing the required knowledge tests you'll get a Commercial Learner's Permit (CLP) valid for 180 days. This permit comes with conditions:

  • You must wait at least 14 days before taking the skills test
  • You can only operate a commercial motor vehicle with a qualified CDL holder in the passenger seat
  • No passengers are allowed except supervisors, trainees or examiners
  • You cannot transport hazardous materials
  • Other restrictions may apply based on vehicle type and endorsements

The endorsements you passed tests for will be on your CLP showing what type of vehicles or cargo you're preparing to operate.

What can I do with my CLP?

With your Commercial Learner's Permit you can practice operating commercial motor vehicles with a qualified CDL holder. This practice time is crucial for developing the skills needed to pass the behind-the-wheel test. You can practice:

  • Vehicle inspection procedures
  • Basic control skills
  • On-road operating techniques
  • Backing and parking maneuvers
  • Route planning
  • Pre-trip and post-trip procedures

Remember you must always have a CDL holder with you in the passenger seat. Use this time to get familiar with the specific vehicle you'll use for the skills test. The more practice you get during this period, the better prepared you'll be for the skills test.

How long are test scores valid?

Your test scores are valid for 180 days, the same as your CLP. If your CLP expires before you take the skills test, you'll have to retake all knowledge tests. There are no extensions on score validity, so plan to take the skills test within the 180-day window. This time limit ensures your knowledge is current when you get your full CDL. So schedule your skills test well before your CLP expiration date to allow time for rescheduling or retests if needed.

What if I fail?

If you fail any part of the knowledge test you must wait until the next business day to retest. You only have to retake the sections you failed, not the entire test. To improve your chances of passing on your next attempt:

  • Use our practice tests to focus on areas where you struggled
  • Review incorrect answers carefully to understand why they were wrong before retesting
  • Try different study methods if you're having trouble with certain topics
  • Review the relevant sections of the Louisiana CDL Manual more thoroughly

There's no limit to how many times you can retest, but repeated failures means you may need more preparation before trying again. Take the time to study properly before going back for another attempt.

How do I schedule the skills test after passing?

After 14 days of holding your CLP you can schedule your skills test:

  • Visit the Louisiana OMV online services or contact your local OMV office
  • Make an appointment with a CDL Third Party Examiner at an authorized testing location
  • Make sure your CLP is still valid and your medical certificate is current before scheduling
  • Arrange for an examination vehicle that matches your CDL class
  • Pay the skills test fee to the examiner when you schedule
  • Choose a date and time from the examiner's available slots that fits your schedule

Remember the skills test consists of three parts: pre-trip inspection, basic control and on-road operating demonstration. Make sure you're prepared for all three before scheduling.
