You’re planning to get your Commercial Driver’s License in North Dakota — and you’re looking at one of the most in-demand states for truckers in the country. North Dakota’s Bakken oil formation has made it a powerhouse for commercial driving jobs, with thousands of haulers moving crude oil, fracking materials, and equipment across the western prairie every day. Add in the state’s massive agricultural output — wheat, soybeans, sugar beets, and livestock — and you have an economy that runs on trucks.
But before you can haul a tanker full of crude out of Williston or move grain from Fargo to Minneapolis, you need to pass the North Dakota CDL exam. The North Dakota Department of Transportation (NDDOT) administers the CDL program under federal FMCSA guidelines, and the process is designed to make sure every driver on I-94 or I-29 can handle an 80,000-pound vehicle safely — through blizzards, high winds, and everything else the Northern Plains throws at you.
This guide gives you everything you need to prepare for the North Dakota CDL test: exact test format, ND-specific requirements, what’s different from other states, and free practice tests covering every knowledge exam you’ll face.

North Dakota CDL Requirements: What You Need to Know
North Dakota follows the federal CDL standards established by the FMCSA under 49 CFR Part 383, with some state-specific requirements administered by the North Dakota Department of Transportation (NDDOT). Here’s exactly what North Dakota requires:
Age Requirements in North Dakota
| License Type | Minimum Age | Restrictions |
|---|---|---|
| Intrastate (ND only) | 18 years | Cannot drive across state lines |
| Interstate (all states) | 21 years | No state-line restrictions |
| HazMat Endorsement | 21 years | Federal requirement — no exceptions |
North Dakota CDL Fees
| Fee Type | Amount | Details |
|---|---|---|
| Commercial Learner’s Permit (CLP) | $15 | Valid for 1 year |
| CDL License Issuance | $15 | Class A, B, or C |
| Knowledge Test | $10 per test | Each separate knowledge exam |
| Skills Test | $50 | Three-part driving exam |
| Endorsement | $5 per endorsement | Each endorsement added |
North Dakota has some of the most affordable CDL fees in the nation. A complete Class A CDL with no endorsements costs roughly $105 total — permit, all three core knowledge tests, skills test, and license issuance. Compare that to states charging $100+ for the license alone.
North Dakota ELDT Requirements
Since February 7, 2022, all new CDL applicants in North Dakota must complete Entry-Level Driver Training (ELDT) through an FMCSA-approved training provider. This is a federal requirement — no state can waive it. NDDOT verifies ELDT completion electronically through the FMCSA Training Provider Registry (TPR).
ELDT is required for:
- Original Class A or Class B CDL
- Upgrading from Class B to Class A
- First-time School Bus (S), Passenger (P), or HazMat (H) endorsements
You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before taking the skills test. Your CLP is valid for 1 year in North Dakota — longer than many states — and can be renewed once if you need more time to practice.
North Dakota CDL Test Format: What to Expect
The North Dakota CDL exam has two parts: knowledge tests (written) and a skills test (driving). The knowledge tests are computer-based, multiple-choice, and administered at NDDOT offices across the state — from Fargo to Williston.
Knowledge Tests Overview
| Test | Questions | Pass Score | Required For |
|---|---|---|---|
| General Knowledge | 50 | 80% (40 correct) | All CDL classes |
| Air Brakes | 25 | 80% (20 correct) | Class A & B (if vehicle has air brakes) |
| Combination Vehicles | 20 | 80% (16 correct) | Class A |
| HazMat (H) | 30 | 80% (24 correct) | HazMat endorsement |
| Tanker (N) | 20 | 80% (16 correct) | Tanker endorsement |
| Passenger (P) | 20 | 80% (16 correct) | Passenger endorsement |
| School Bus (S) | 20 | 80% (16 correct) | School bus endorsement |
| Doubles/Triples (T) | 20 | 80% (16 correct) | Double/triple trailers |
All North Dakota CDL knowledge tests follow FMCSA content standards from the North Dakota Commercial Driver License Manual. NDDOT even provides audio versions of the manual — a helpful option if you learn better by listening during long drives across the state. The passing score is 80% on every test, no exceptions.
North Dakota Skills Test: Three Parts
The North Dakota CDL skills test is administered by NDDOT-approved Third-Party Testers. You must provide your own vehicle for the test, and it must be the same class of vehicle you’re applying for.
| Section | What It Tests | Details |
|---|---|---|
| 1. Pre-Trip Inspection | Vehicle safety knowledge | Verbally identify and explain critical components: engine, brakes, tires, lights, coupling systems |
| 2. Basic Vehicle Control | Backing and maneuvering | Straight-line backing, offset backing (right/left), parallel parking, alley dock |
| 3. On-Road Driving | Real-world driving | 45–60 minutes covering urban, rural, and highway driving — turns, lane changes, stops, intersections, railroad crossings |
North Dakota skills test retake policy: If you fail the skills test, you must wait 14 days before retaking it. For knowledge tests, you can retake the next business day — one of the shortest waiting periods in the country. There’s no cap on retake attempts within the 1-year permit period. The skills test costs $50 per attempt.
What Makes North Dakota CDL Different from Other States?
The core CDL exam is federally standardized — the General Knowledge, Air Brakes, and endorsement tests cover the same material in every state. But North Dakota has specific characteristics that make driving here unlike anywhere else:
North Dakota-Specific Driving Conditions
- Bakken Oil Boom: The Williston Basin in northwestern ND is one of the most active oil regions in North America. Tanker and HazMat endorsements are in extreme demand here — driving crude oil, fracking sand, and produced water is a way of life for thousands of CDL holders
- Brutal winters: North Dakota is one of the coldest states in the Lower 48. Blizzards routinely close I-94 and I-29, temperatures drop to -30°F or lower, and black ice on bridges is a constant threat. Diesel fuel gelling, battery failures, and extended warm-up times are everyday realities
- Extreme wind: The open prairie offers no windbreaks. Sustained 30–50 mph winds are common, with gusts exceeding 70 mph. Empty trailers and lightly loaded boxes are at serious risk of tipping — especially on the I-94 corridor between Bismarck and Fargo
- Two critical interstates: I-94 runs east-west connecting Fargo, Bismarck, Jamestown, and Williston. I-29 runs north-south from the Canadian border through Grand Forks and Fargo. Nearly all interstate freight in ND travels these two corridors
- Long distances between services: Western North Dakota is sparsely populated. A breakdown between Belfield and Minot can mean a long wait for help. Route planning and emergency preparedness aren’t optional — they’re survival skills
- Spring load restrictions: During spring thaw, ND enforces seasonal weight restrictions (frost laws) on many roads to prevent pavement damage. The state also has a 129,000-pound Large Truck Network for qualified carriers running heavier loads
- Canadian border crossings: I-29 connects to Canada at the Pembina–Emerson port of entry. Drivers hauling north need to understand international shipping documentation and border procedures
- Agricultural powerhouse: ND is a top producer of wheat, soybeans, canola, and sugar beets. Grain hauling is seasonal but massive — flatbed and hopper-bottom work surges during harvest season from August through October
While the CDL knowledge test itself won’t ask you North Dakota-specific questions beyond what’s in the standard handbook, understanding these conditions will make you a safer driver and help you contextualize the safety rules you’re learning. If you’re heading to the Bakken, winter driving skills and HazMat knowledge aren’t just test topics — they’re what keeps you alive.

How much does a North Dakota CDL cost?

Can I get a North Dakota CDL at 18?
Yes. North Dakota allows you to get a CDL at 18 for intrastate driving only (within North Dakota). You cannot cross state lines until you turn 21. The HazMat endorsement requires you to be at least 21, regardless of your license type.

North Dakota CDL skills tests are administered by NDDOT-approved Third-Party Testers. Testing is available at NDDOT offices in Bismarck, Fargo, Grand Forks, Williston, Minot, Dickinson, Jamestown, and Devils Lake.

Is the North Dakota CDL test the same as other states?
The knowledge tests are based on the same FMCSA standards and cover the same material as in every other state.
