Checked against official Delaware sources on Oct 8, 2026
Delaware CDL practice test
Every state needs at least 80% on each CDL written test, and Delaware follows the same federal rule. Below are the fees, ages and rules we checked against the official Delaware 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.
