What the Course Entails and Exam Details

The course curriculum covers a wide array of topics critical to commercial driving safety. Key areas include general knowledge about vehicle control and inspection, advanced safe driving practices, and the regulations surrounding the transport of cargo. Depending on the class of license you are seeking, you will also cover specific endorsements such as Air Brakes, Combination Vehicles, Doubles/Triples, Tankers, Hazardous Materials (HazMat), and Passenger Transport. Mastery of these subjects ensures that you are ready for both the knowledge and the road skills portions of the licensing process.


What to Expect in the Final Exam

The official Mississippi CDL knowledge test is a multiple-choice exam administered on a computer at a Mississippi Department of Public Safety (DPS) location. To pass the exam, you must achieve a score of at least 80%, which usually translates to answering 40 out of 50 questions correctly on the General Knowledge portion. There are typically time limits in place for each section to ensure efficiency, so you should be prepared to answer promptly and accurately. No outside assistance or electronic devices are permitted during the examination.

Engage in consistent practice by taking online practice tests that simulate the real exam experience. Pay close attention to sections covering your desired endorsements and revisit areas where you frequently miss questions. To take the official exam, you must visit a Mississippi DPS Driver Service Bureau. It is advisable to make an appointment in advance as testing centers can be busy. While authorized schools can facilitate training, the knowledge test itself is almost always conducted at a DPS center.
