North Dakota CDL Practice Tests - All Endorsements

The tests listed above cover the same written exam every commercial driver in the country has to pass, so a little context helps before you dive in. The CDL general knowledge test is 50 questions, and you need 80 percent, meaning 40 correct, to pass. That standard comes from the federal FMCSA and it is the same in every state. This is also the written exam for your Commercial Learner’s Permit, so a North Dakota CDL permit practice test and a general knowledge practice test are one and the same thing.

Whether you are going for Class A, B, or C, you take that identical written test. What separates the classes is your skills test and the vehicle you actually drive, not the questions on the screen. So start with any general knowledge test above, work through it a few times, then layer in the endorsements your route demands.

In North Dakota, those endorsements often decide your paycheck. The Bakken keeps rigs, water haulers, and chemical trucks moving day and night, which puts Tanker and HazMat drivers in constant demand for crude, produced water, and the fluids that keep wells running. Add the fall grain rush, when wheat, soybeans, and sugar beets flood the elevators, and you can see why serious drivers here treat those separate knowledge tests as core skills rather than nice-to-haves. Each endorsement, whether Air Brakes, Combination Vehicles, Doubles/Triples, Passenger, or School Bus, has its own exam and its own section to master.

Give real attention to the topics that keep you upright on I-94 in January. Pre-trip vehicle inspection, basic control, shifting a loaded rig, managing space and speed, and reading hazards early all matter more when crosswinds are howling and black ice hides on the overpasses. Emergency response, from brake failure to skid recovery, deserves slow, repeated study, not a quick skim.

Pull open the North Dakota Commercial Driver License Manual from NDDOT alongside your practice runs. Read a chapter, take a sample CDL exam, then go back to whatever tripped you up. The free CDL practice tests here need no login, so you can drill as often as you want. When your scores hold steady in the 90s, schedule your CDL skills test with the NDDOT, Driver License Division, and go earn the classification your job calls for.
