About the West Virginia Hazardous Materials test
The questions come from the West Virginia CDL manual, they are multiple choice, and you need 80% to pass, the same standard as every other CDL knowledge test. West Virginia Division of Motor Vehicles gives it, and you sit it on top of the General Knowledge test rather than instead of it.
The H endorsement lets you haul hazardous materials in quantities that require placarding. It is the one endorsement with a federal security step attached: a TSA security threat assessment including fingerprinting, which is a separate application and a separate fee, and it has to be renewed along with the endorsement.
It is not the same in every state
The questions come from the same federal pool wherever you sit the test, but the rules around it are set by each state. Three real examples of what differs:
- Arizona: A Class C CLP must carry the Passenger endorsement and cannot carry HazMat.
- California: A CLP can only carry Tank, Passenger, and School Bus endorsements; HazMat is added to the CDL after the TSA check.
- Colorado: The CDL knowledge test is offered in English and Spanish, but the HazMat test is English only.
Quoted from each agency's own published guidance. Check West Virginia Division of Motor Vehicles for the rules that apply to you.

Common questions
How long is the HazMat test?
Your state sets the number of questions. Federal rules require each knowledge test to draw from an approved pool but do not fix a count per endorsement, so ask West Virginia Division of Motor Vehicles for its test length. The pass mark is 80%.
Is a background check required for the H endorsement?
Yes. HazMat is the one endorsement with a federal security step: a TSA security threat assessment that includes fingerprinting. It is a separate application with its own fee, it takes time to come back, and it has to be redone when the endorsement is renewed. Start it early rather than after you pass the test.
What is the X endorsement?
X is what you hold when you carry both H (hazardous materials) and N (tank vehicles). It is not a seventh subject or a separate test, just the combination, and it is the normal case for hauling placarded liquid loads.
What does the HazMat test cover?
The hazardous materials section of the CDL manual and the rules behind it in 49 CFR: the hazard classes, the shipping papers and who is responsible for them, placarding, marking and labelling, loading and segregation rules, and what to do when there is a leak or an incident.
