How Many Questions Are on the Arkansas CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — Arkansas's OMV administers the federal format rather than writing its own.
A fee structure most states don't split this way
The federal government owns the question count and 80% threshold. Arkansas's own twist: the CLP itself carries no fee at all, but taking the knowledge test to qualify for one costs $50.
Depending on the class and endorsements pursued, additional tests — like Air Brakes or Combination Vehicles — may also apply on top of the General Knowledge test.
A six-month CLP window
Once issued, an Arkansas CLP stays valid for six months.
Once you pass the skills test, the commercial driver's license itself carries a separate $42 fee — bringing a complete CDL to roughly $92 total.
How our practice tests are structured
Our practice tests break results down by topic immediately, so a weak spot doesn't stay hidden inside an otherwise decent overall score.
Each question includes an explanation and a source reference, so you learn why an answer is correct instead of just memorizing a letter.
