All of our practice material is built from the official North Dakota CDL handbook and federal resources, and curated by professionals with over 10 years of experience in the commercial transportation industry. Studying with practice tests that mirror the real exam format is one of the most effective ways to pass on your first try.

Class B CDL
Single vehicles over 26,001 lbs GVWR. Common for straight trucks, large buses, dump trucks, and box trucks.
Endorsements
HazMat, Tanker, Doubles & Triples, and Passenger are add-ons for specific job requirements. If you're unsure, you don't need them — they can be added later.

Your Path to a Commercial Driver's License
To get a CDL, you must first study for and pass the permit exam at the DMV. After you receive your permit, you can take commercial vehicle driving classes and complete the required training. The final step is passing the official driving exam to earn your CDL. Our practice tests help you prepare for the DMV permit exam with real-style questions, and we also provide extra study materials and helpful resources to guide you through the process.
Official North Dakota CDL Handbook
The official North Dakota CDL Manual covers every topic tested on the state's CDL knowledge exam — but it reads like a dense reference manual, not a structured study guide. A more effective way to prepare is with our General Knowledge practice tests. Our free North Dakota CDL permit practice test mirrors the format and content of the official exam and is fully up to date as of February 2026. Each practice test features 20 questions covering essential topics such as vehicle inspection, safe driving techniques, air brakes, cargo securement, driving emergencies, hazardous conditions, and North Dakota-specific commercial driving regulations. Unlike the official test, every practice question comes with a helpful hint and a detailed explanation of the correct answer — so you actually learn from every question you answer.
- Complete CDL regulations and North Dakota-specific requirements
- Safe driving techniques, vehicle inspection, and cargo handling
- All endorsement categories and testing requirements
Non-Domiciled CDL Information
Important information about non-domiciled commercial driver's licenses in North Dakota.
Federal regulations on non-domiciled CDLs are changing rapidly. The information below reflects the latest known state actions.
North Dakota does issue non-domiciled CDLs and CLPs. The word "Non-Domiciled" must be prominently displayed on the CDL or CLP. The non-domiciled CLP fee is $20 (vs. $15 for residents). North Dakota has not been publicly identified as being under an FMCSA corrective action plan. Under the FMCSA final rule published on February 13, 2026, eligibility for non-domiciled CLPs and CDLs is limited to foreign-domiciled individuals holding specific employment-based nonimmigrant statuses — such as H-2A, H-2B, and E-2 visa holders. Individuals under humanitarian or deferred status categories are no longer eligible. State Driver's Licensing Agencies must verify applicant status through the SAVE database. North Dakota is expected to comply with these federal requirements. Affected drivers should contact NDDOT at 1-855-633-6835 for the most current information.[FMCSA Final Rule]
English Language Proficiency (ELP)
Federal ELP enforcement applies to all CDL holders nationwide.
Federal ELP enforcement applies to all CDL holders nationwide. Here is how it is enforced in North Dakota.
North Dakota does not currently administer a separate state-level English Language Proficiency (ELP) test for CDL applicants. However, all North Dakota CDL holders are subject to federal ELP enforcement, which took effect on June 25, 2025. Under this enforcement, roadside inspectors conduct a two-step assessment: first, a conversational interview in English — no interpreters or translation tools are permitted — to evaluate whether the driver can communicate sufficiently in English; second, the driver must demonstrate the ability to read and interpret standard U.S. traffic signs. Drivers who fail either step of the assessment are placed out of service under CVSA guidelines. North Dakota CDL applicants should be prepared to demonstrate English proficiency during any roadside inspection or compliance review.
