How Many Questions Are on North Dakota's CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — North Dakota administers the federal format through its Department of Transportation rather than writing its own.
A fee structure with a residency split
The federal government owns the question count and 80% threshold. North Dakota's own fees run $5 per knowledge test attempt, $3 per additional endorsement, and $5 per skills test attempt.
The CLP itself costs $15 for a resident, but $20 for a non-domiciled applicant — a genuine two-tier fee based on residency.
Extra training for a first-timer
A first-time Class A or Class B applicant must also complete entry-level driver training (ELDT) through an authorized provider, on top of the knowledge and skills tests.
Original documents or certified copies are required for every supporting document; a photocopy isn't accepted.
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.
