Louisiana CDL Practice Test

Louisiana’s OMV doesn’t publish its test sizes. Our practice tests follow the usual CDL format: General Knowledge 50 questions (40 to pass), Hazmat 30 (24), Air Brakes 25 (20), and Combination, Tank, Doubles/Triples, Passenger and School Bus 20 each (16 to pass).

Class A for combinations of 26,001 pounds or more towing over 10,000 pounds, Class B for single straight vehicles of 26,001 pounds or more, and Class C for smaller vehicles carrying 16 or more people (driver included) or placarded hazardous materials. Commercial vehicles from 10,001 to 26,000 pounds need a Class D chauffeur’s license. Louisiana Commercial Driver License Manual p. i

18 to drive commercially within Louisiana and 21 to drive across state lines. The hazardous materials (H) endorsement is issued only to drivers 21 or older. Louisiana Commercial Driver License Manual p. i to ii

Be 18 or older with a valid Louisiana license, be medically certified, complete the CDL Supplemental Form (DPSMV 2211), prove Louisiana residency and pass the knowledge tests. A CDL holder with the right class and endorsements must sit in the front seat beside you whenever you drive.

Up to 180 days, with one free 180-day extension if you need more training; it can’t run past 360 days from first issue. You can’t take the skills test in the first 14 days after the CLP is issued.

A CDL third-party tester, by appointment: the test covers the pre-trip inspection, basic controls and road driving. After you pass, return to the Office of Motor Vehicles for your CDL. Louisiana Commercial Driver License Manual p. iii

Yes, if you are getting a Class A or B CDL for the first time, upgrading from B to A, or adding a school bus (S), passenger (P) or hazmat (H) endorsement for the first time. Training must come from a provider in FMCSA’s Training Provider Registry.

A document showing your name and Louisiana address, such as a voter registration card, a property tax receipt, a lease or rental agreement, a utility or phone statement, a W-2, a current home, health or car insurance policy, or a letter from your local postmaster confirming you receive mail there.

Yes, if you are attending a driver training school. You can train on a CLP together with your home state's driver's license, but the permit and the license must come from the same state, and you still meet the usual CLP requirements.

Form DPSMV 2211 records the type of commerce you drive in. You complete it when you first apply for a CLP and again whenever your kind of driving changes, for example from Louisiana-only work to trips that cross state lines.

Interstate if any trip, or the cargo's journey, crosses a state or national border; intrastate if everything stays in Louisiana. Then choose excepted or non-excepted. If you drive both ways, certify interstate, and if you mix excepted and non-excepted interstate work, certify non-excepted.

Only for vision. Louisiana's own waiver program covers vision alone, and drivers who stay within the state otherwise follow the federal medical rules Louisiana has adopted. City, municipal and state employees with a CDL are examples of excepted intrastate drivers.

Not for a valid Class A, B or C CDL from another state: no written or skills tests, except that a hazmat endorsement needs its knowledge test passed before the license is issued. Bring your photo license or a driving record from your last state; the old license is surrendered.

Not always. The OMV may let a farmer, a family member or an employee drive a farm vehicle on a Class D or E license when it carries crops, machinery or supplies to or from the farm within 150 miles, not for hire. The driver needs a clean record and a previous license.

No CDL is needed to drive commercial vehicles for military purposes. If your Louisiana CDL expires during your enlistment, it still works as a regular Class E license for non-military driving while you serve full time and for up to 60 days after you leave.

You need 20/40 in at least one eye, a wide enough field of vision, normal red, green and amber recognition, two years of commercial driving in the last five, and a third-party skills test after your diagnosis. With the waiver you drive only in Louisiana, with no paid passengers or placarded hazmat, and reapply at each renewal.

Only passenger (P), school bus (S) and tank (N). With P or S you may not carry passengers other than examiners, inspectors, other trainees and your accompanying CDL holder; with N you may drive only an empty, purged tank vehicle. Louisiana Commercial Driver License Manual p. 1-2 to 1-3

A TSA security threat assessment (fingerprints through TSA’s enrollment provider) and a passed hazmat knowledge test, for every new, renewed or transferred H endorsement. First-time applicants also complete entry-level training before the knowledge test.

Expired or downgraded for at least one year: pass the knowledge tests for your class and endorsements again. For two years or more: the skills test as well, in a vehicle of the same class.

Since November 18, 2024, a driver with a “prohibited” status in FMCSA’s Clearinghouse loses, or is denied, a Louisiana CDL or CLP until the return-to-duty process is complete.

Yes, if your TSA security threat assessment is no more than six months old and can be verified. If it is older, apply for a new one: you can transfer the CDL without the hazmat endorsement first and add it once the new assessment clears.

Proof of identity, your Social Security number, proof of Louisiana residency, a current medical examiner's certificate and, if it applies to you, proof of liability insurance. You also pass a vision test and any tests your license requires, such as the hazmat knowledge test.

Yes, for ten years. A DUI conviction, or refusing a chemical test after a DUI arrest, in any vehicle bars you from driving a school bus for a decade. After five years with no further DUI or refusal, and after finishing an approved alcohol or drug treatment or education program, you can ask to have the S endorsement back.

No. Louisiana gives no hardship license for driving commercial vehicles. A disqualification also stands when a conviction is later set aside or dismissed under the Code of Criminal Procedure, unless that happens on appeal, and being sent to a pretrial diversion program still counts as a conviction.

Usually. Once any suspension from the offense is over, and if your regular driving privileges are valid, you surrender the CDL and get a Class D or E license for as long as the disqualification lasts. When commercial privileges come back, the CDL is returned to you, or you renew it if it expired in the meantime.

It can make you retake the knowledge test, the skills test or both, even without a conviction. You must book the next available test within 30 days of the notice. Miss that deadline, fail or skip the retest, and your commercial privileges are disqualified indefinitely; you then start over as a new applicant.

No. Louisiana issues the T endorsement for doubles and triples, but state law says the endorsement doesn't permit triple-trailer combinations on Louisiana roads. The T endorsement and its knowledge test are still what you need for pulling doubles.
