Checked against official Missouri sources on Oct 7, 2026
Missouri CDL practice test
Every state needs at least 80% on each CDL written test, and Missouri follows the same federal rule. Below are the fees, ages and rules we checked against the official Missouri source, and a free practice test.
FirstTry CDL is not affiliated with any DMV, FMCSA or government agency. Practice questions are exam-style questions built from the official CDL manual, not actual test questions.
