ProAbout the North Dakota CDL Knowledge Test
To obtain a Commercial Driver's License in North Dakota, you must first pass the CDL general knowledge written test administered by the NDDOT. The general knowledge exam consists of 50 multiple-choice questions covering vehicle inspection, basic control, safe driving, transporting cargo, and federal regulations. A score of 80% or higher (40 correct) is required to pass.
CDL Classes and Endorsements
North Dakota issues three CDL classes. Class A covers combination vehicles over 26,001 lbs GVWR when the towed unit exceeds 10,000 lbs - this is what you need for tractor-trailers and most heavy hauling. Class B covers single vehicles over 26,001 lbs such as straight trucks, large buses, and dump trucks. Class C covers vehicles designed for 16+ passengers or those carrying hazardous materials that don't meet Class A or B criteria.
Beyond the general knowledge test, you may need additional written tests for endorsements: Hazardous Materials (H), Tanker (N), Passenger (P), School Bus (S), Doubles/Triples (T), or the combined HazMat-Tanker (X). Each endorsement requires its own written exam, and HazMat also requires a TSA background check.
Entry-Level Driver Training (ELDT)
Since February 2022, federal law requires Entry-Level Driver Training (ELDT) through an FMCSA-registered training provider before you can take the CDL skills test for a Class A or B CDL. ELDT is also required before adding Hazardous Materials, Passenger, or School Bus endorsements. This applies in North Dakota and every other state.
Where to Take the Test
The CDL knowledge test is taken at any North Dakota DOT driver license office, or remotely via KnowToDrive online testing. Walk-ins are typically accepted, though scheduling ahead is recommended. The test is available in English, Arabic, Spanish, Somali. Results are delivered immediately - results shown on screen after completing the test (both in-person and online).
Preparing for Your CDL Test
The CDL test draws from the North Dakota CDL Manual and the federal Motor Carrier Safety Regulations. Key topics include pre-trip vehicle inspection procedures, air brake systems, coupling and uncoupling, cargo securement, hours-of-service rules, hazard perception, and accident procedures. North Dakota-specific regulations on weight limits, required permits, and designated truck routes may also appear.
Taking practice tests before your appointment is one of the most effective ways to prepare. Focus on understanding road signs and the concepts behind each question rather than memorizing answers - the real test may phrase questions differently than what you studied.
Retake Policy
You cannot retake a failed exam the same day, so the earliest retake is the next day, with 1 attempt per day. Each knowledge-test attempt costs $5, and the road test is a separate $5. NDDOT does not publish a limit on the total number of attempts.
