Requirements before you test
Arkansas 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 Arkansas Driver Services is Arkansas’s own, and may be stricter than the federal floor. Test length, fees, and scheduling are set by Arkansas Driver Services (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 Arkansas 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 Arkansas non-commercial knowledge test runs 25 questions and needs 20 correct, with permits issued from age 14.

5 Arkansas CDL practice questions
Try these Arkansas 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. Before loading, unloading, or moving a tanker, intake/discharge/cut-off valves must be:
- AWired fully open always
- BLeft randomly open
- In the correct position for the operation
- DRemoved
Answer: In the correct position for the operation. Wrong valve positions cause spills. Also check pipes, hoses, joints, manhole covers, and vents.

2. When a school bus is equipped with ABS, hard braking is helped because ABS can:
- AAllow higher speeds into loading zones
- BGuarantee a shorter stop every time
- Reduce wheel lock so you can steer and keep control
- DReplace the need for mirror checks
Answer: Reduce wheel lock so you can steer and keep control. Brake normally. ABS adds to ordinary brakes and is not permission to drive faster.

3. A converter dolly typically connects to the front trailer with a:
- ALanding-gear foot only
- BGlad-hand electrical plug
- CFifth wheel only on the tractor
- Pintle hook and safety chains or cables as required
Answer: Pintle hook and safety chains or cables as required. Inspect the pintle, hitch, and safety devices carefully before coupling the second trailer.

4. If you suspect a fire in the cargo area of a sealed van trailer, you should:
- AContinue driving to the next terminal
- BSpray water through the door seals
- COpen the doors immediately to see the fire
- Keep the doors shut and wait for firefighters
Answer: Keep the doors shut and wait for firefighters. Opening the doors feeds the fire oxygen and can cause it to flare violently. Park away from others and call for help.

5. A few light taps on the brake pedal are used mainly to:
- Flash the brake lights and warn drivers behind that you will slow
- BTest ABS
- CDrain air tanks
- DCool the brakes
Answer: Flash the brake lights and warn drivers behind that you will slow. Light taps flash the brake lights without a hard stop, giving following drivers time to react.
