Missouri CDL Practice Tests - All Endorsements

Two of the country’s biggest freight hubs sit at opposite ends of Missouri. Kansas City and St. Louis move rail and truck cargo on a national scale, the I-70 and I-44 corridors carry loads straight across the state, and grain, livestock, and barge freight off the Mississippi and Missouri rivers keep trucks rolling year round. If you want a seat in that economy, it starts with a commercial license, and the Missouri CDL practice test above points you at the right first exam.

Here is what that exam looks like. The CDL general knowledge test runs 50 questions, and passing takes 80 percent, or 40 right answers. That threshold comes from federal FMCSA rules, so it holds steady from Missouri to any other state. The same written test doubles as the exam for your Commercial Learner’s Permit, which is why a Missouri CDL permit practice test and a general knowledge test cover identical ground. It also does not matter yet whether you are chasing a class A, B, or C license. Every applicant takes this one written test, and the class is settled by your skills test and the truck you drive.

Work through the practice questions above until the core subjects feel routine: inspecting your vehicle before every trip, controlling the rig at low speed, shifting smoothly, keeping safe following distance, reading the road for hazards, and reacting when something goes wrong. Keep the Missouri Commercial Driver License Manual open while you study so each answer connects to a rule you actually understand.

Endorsements are graded as their own knowledge tests, and Missouri’s freight profile hints at which ones pay off. Combination Vehicles and Air Brakes fit the long-haul tractor-trailers on I-70 and I-44, Tanker and HazMat suit the fuel and ag-chemical loads tied to farm country and river terminals, and Doubles/Triples matches the sprawling distribution network around both metros. Passenger and School Bus stay open if transit work appeals to you.

In Missouri the license is issued by the Department of Revenue, while the testing itself is handled by the State Highway Patrol. Once your scores sit comfortably above passing, schedule your CDL skills test with the Missouri Department of Revenue, and go earn it.
