How Many Questions Are on the Kansas CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — Kansas's Division of Vehicles administers the federal format rather than writing its own.
A permit fee split into two small pieces
The federal government owns the question count and 80% threshold. Kansas's own twist: the CLP itself runs $5, plus an $8 photo fee, for about $13 total.
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 longer CLP window than many states allow
Once issued, a Kansas CLP stays valid for 12 months — longer than the six-month window several neighboring states use.
You still need to hold that CLP at least 14 days before scheduling the CDL skills test, even with a full year to work with.
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.
