Start with the Missouri CDL manual
FMCSA directs drivers to use their own state's CDL manual for knowledge testing. Federal H-endorsement rules define the shared scope, while states administer the program and publish the current test process.
The federal minimum score is 80%. Question count, time limit, state fee, retake wait, and renewal cycle remain unlisted here until a dated Missouri primary source verifies each one.
First-time H applicants must complete ELDT theory with a registered provider before the state knowledge test. VoltExam does not provide ELDT credit.

Missouri CDL Hazmat questions
How many questions are on the Missouri CDL Hazmat test?
Missouri Department of Revenue (licensing); Missouri State Highway Patrol (testing) controls the current test format. Check its current CDL manual or testing page for the question count and time limit. FMCSA sets a minimum score of 80% for knowledge and endorsement tests, but that does not establish one nationwide question count.
Which manual should I use for the Missouri Hazmat test?
Use the current Missouri CDL manual linked by the state licensing agency. VoltExam is supplemental federal-scope practice; it does not replace the state manual or state-specific instructions.
What do the Missouri endorsement and TSA assessment cost?
Confirm current state fees with Missouri Department of Revenue (licensing); Missouri State Highway Patrol (testing) and current federal enrollment fees with TSA before paying. VoltExam does not publish an exact fee without a dated primary source.
Do first-time Hazmat applicants need ELDT?
Yes. FMCSA requires first-time H-endorsement applicants to complete the Hazmat theory portion of Entry-Level Driver Training through a registered provider before the state knowledge test. VoltExam is supplemental practice and is not an ELDT provider.
What happens if I fail or need to renew in Missouri?
Retake waits, fees, and renewal steps are state-administered and can change. Confirm the current policy with Missouri Department of Revenue (licensing); Missouri State Highway Patrol (testing); this page intentionally does not infer those details from another state.
