How Many Questions Are on the Utah CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — the Utah Driver License Division administers the federal format rather than writing its own.
What Utah actually controls
The federal government owns the question count and 80% threshold. Utah bundles its own $52 CLP fee with all three required written knowledge tests, rather than charging per test — a retake beyond two attempts costs $26 extra per test.
Depending on the class and endorsements pursued, a HAZMAT background check runs an additional $80-110 and takes 30-90 days to clear.
A skills test that bundles issuance
Once you're ready to move from the CLP to the full CDL, the $78 skills test fee already includes CDL issuance — no separate charge once you pass.
Rescheduling that skills test appointment costs an extra $25, worth planning around rather than risking.
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.
