Louisiana CDL Practice Test
Free practice questions for the Louisiana commercial driver license written exams — general knowledge, air brakes, combination vehicles, and every endorsement.
Louisiana's Office of Motor Vehicles (OMV), a division of the Louisiana Department of Public Safety, oversees driver licensing and vehicle registration throughout the state. Unlike some states that administer written tests directly through government offices, Louisiana's knowledge tests and road tests are conducted through licensed private driving schools, giving applicants flexibility in scheduling and testing locations. The state's learner's permit program begins as early as age 15 with the Temporary Instructional Permit (TIP), allowing young drivers to gain supervised driving experience. Louisiana offers testing in multiple languages including Spanish, Vietnamese, and Chinese, making the licensing process more accessible to non-English speakers. The state's approach emphasizes partnering with professional driving schools to ensure quality instruction and testing. Whether you're a teenager pursuing your first license or a new resident, Louisiana provides a structured path through its private school network to achieve your driving credentials.
About this section of the Louisiana test
Louisiana's commercial driver license program requires passing a 50-question written knowledge test with a minimum score of 80%. Applicants must be at least 18 years old, though drivers under 21 cannot transport hazmat or operate out-of-state. You must first obtain a Commercial Learner's Permit (CLP) and hold it for at least 14 days before taking the driving skills test. All CDL applicants must pass a DOT medical examination and complete Entry-Level Driver Training (ELDT). Louisiana offers various CDL endorsements for specialized vehicle types and cargo.
