Requirements before you test
West Virginia CDL test requirements
Commercial licensing is largely federal. Any figure above credited to a 49 CFR section applies in every state — see 49 CFR 383.135(a)(1) and 49 CFR 383.25(e). A figure credited to West Virginia Division of Motor Vehicles is West Virginia’s own, and may be stricter than the federal floor. Test length, fees, and scheduling are set by West Virginia Division of Motor Vehicles (official source).
Entry-Level Driver Training comes first
Since February 7, 2022, a new Class A or Class B CDL, a class upgrade, or a first passenger, school bus, or hazardous materials endorsement requires training from a provider on the FMCSA Training Provider Registry (49 CFR 380.600). Practice questions are study material and do not satisfy that requirement.
FMCSA Training Provider RegistryYou need a West Virginia licence first
A commercial learner’s permit only counts if you already hold an ordinary licence from the same state (49 CFR 383.25(a)(2)). The West Virginia non-commercial knowledge test runs 25 questions and needs 19 correct, with permits issued from age 15.

5 West Virginia CDL practice questions
Try these West Virginia sample questions now — each shows the correct answer with a plain-language explanation and a source section. The full 600-question bank is in the practice run.
1. If a vehicle lacks racks for Class 2 cylinders, the cargo floor must be flat and cylinders must be:
- ATied by their valve wheels only
- BLoose so they can roll to vents
- Held upright in racks or boxes that prevent tipping (unless designed for horizontal loading)
- DStacked on the sleeper bunk
Answer: Held upright in racks or boxes that prevent tipping (unless designed for horizontal loading). Horizontal loading is allowed only for cylinders designed so the relief valve stays in the vapor space.

2. Segregation rules exist so that:
- ADrivers can skip papers
- BPlacards become unnecessary
- CAll hazmat rides in the cab
- Incompatible materials are not loaded together where they could react dangerously
Answer: Incompatible materials are not loaded together where they could react dangerously. Before loading mixed products, check whether they may travel in the same vehicle—ask your employer if unsure.

3. Cargo tanks and other bulk packaging often display the material’s identification number on:
- AThe fuel receipt only
- BMirror housings
- CThe driver’s license
- Placards or orange panels
Answer: Placards or orange panels. Four-digit UN/NA numbers help responders look up the product in the Emergency Response Guidebook.

4. A placarded vehicle must normally display identical placards on:
- AThe driver’s door only
- BThe rear only
- Front, rear, and both sides
- DThe roof only

5. Hazard labels on packages are generally:
- Diamond-shaped, about four inches on a side
- BOnly black-and-white rectangles
- COptional if placards are used
- DRound green stickers
Answer: Diamond-shaped, about four inches on a side. Nine hazard-class label designs warn handlers of package risks; placards warn about the vehicle.
