About the Missouri CDL General Knowledge test simulator
The Missouri CDL general knowledge test is the written exam standing between you and a commercial driver's license, and this simulator recreates it faithfully for 2026. Use it as your final commercial drivers license test rehearsal, matching the real CDL knowledge test in length, difficulty, and subject coverage.
How many questions are on the Missouri CDL exam, and what score do you need? The general knowledge test contains 50 questions, and passing requires 80 percent, which works out to 40 correct answers. That threshold comes from federal FMCSA rules, so it is the same across Missouri and the rest of the country.
Every question draws on the Missouri Commercial Driver License Manual, covering vehicle inspection, safe control, space and speed management, and hazard response. Take this CDL knowledge test simulator until you clear 40 out of 50 without hesitation, then book your official exam with confidence.
Every question traces back to the Missouri CDL Manual - skim the right-of-way and signs chapters before your retake.
