How Many Questions Are on the Minnesota CDL General Knowledge Test?
50 questions. That number comes from 49 CFR Part 383, a federal regulation applied identically in Minnesota and every other state — the DVS doesn't get to change it.
Federal test, state-run process
The General Knowledge test's question count and passing threshold are fixed nationwide. What Minnesota's Driver and Vehicle Services actually controls is everything around the test itself: the $26.75 CLP fee, the requirement to already hold a Class D license, and the 14-day minimum hold before the skills test.
Depending on the class and endorsements you're pursuing, additional tests — like Air Brakes or Combination Vehicles — may also apply on top of the General Knowledge test.
Since February 2022: ELDT
Federal entry-level driver training (ELDT) through an FMCSA-registered provider has been mandatory for new CDL applicants since February 7, 2022 — a genuinely recent requirement layered on top of the knowledge and skills tests.
Skipping ELDT means the skills test can't be scheduled at all, regardless of how well you scored on the knowledge test.
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.
