About the Tennessee CDL General Knowledge test simulator
How many questions does the Tennessee CDL general knowledge test have? Fifty, and you need 40 correct, an 80 percent score, to pass, a rule set by federal FMCSA and applied the same way nationwide. This Tennessee CDL general knowledge test practice page mirrors that exact structure.
This commercial drivers license test drill pulls from every chapter of the Tennessee CDL Manual, giving a realistic spread rather than a narrow focus, matching the mix of recall and scenario questions used on the real cdl knowledge test.
Candidates chasing Class A, Class B, or Class C all take this identical written exam. Sit through the full set, score yourself honestly, and treat anything under 80 percent as a signal for another pass through the manual.
Every question traces back to the Tennessee CDL Manual - skim the right-of-way and signs chapters before your retake.
