Missouri CDL General Knowledge Practice Test 3 2026

This Missouri CDL practice test works whether you are aiming for a Class A or a Class B commercial license, because the written general knowledge exam is identical for both. Drivers hunting for a CDL A practice test or a CDL Class B practice test get the same core questions here, since your class is decided later by your skills test and vehicle.

These test questions for CDL applicants cover the fundamentals every Missouri trucker must know: inspection, control, space, speed, and reacting to hazards. The exam runs 50 questions with an 80 percent passing score, meaning 40 right answers, under the federal standard that applies statewide in 2026.

Once the written material feels solid, the Class A or Class B distinction comes down to the equipment you train on. Keep the Missouri Commercial Driver License Manual close, run this practice test until the answers come quickly, and you will walk into the Missouri exam ready for either class.
