How Many Questions Are on Montana's CDL General Knowledge Test?
50 questions. That count is fixed by 49 CFR Part 383, the same across every state — Montana administers the federal format at its Motor Vehicle Division offices rather than writing its own.
A fee structure worth double-checking before you assume
The federal government owns the question count and 80% threshold. Montana's own license fees are $56.25 for a Class A, $61.50 for a Class B, and $41.25 for a Class C — notably, Class B actually costs more than Class A, even though Class A generally covers larger combination vehicles.
The knowledge test itself is given at a Motor Vehicle Division office, not online or by mail.
Original documents, not photocopies
Every supporting document a Montana CDL applicant brings in must be an original or a certified copy — a photocopy isn't accepted, so it's worth confirming exact requirements with the MVD before your appointment.
Federal rule also requires entry-level driver training (ELDT) through an authorized provider before your first CDL, regardless of your license class.
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.
