How to Pass the North Dakota NDDOT Written Test

Proven study tips, the highest-priority topics, and test-day strategies for the 2026 North Dakota driver knowledge test.

📋 Know the Test Format

The North Dakota Class D knowledge test consists of approximately 25 questions. You need to answer at least 20 correctly (80%) to pass. You may take the test at any NDDOT driver license office (appointment required) or online at nd.knowtodrive.com. Note: if you pass online, you must still visit a NDDOT office to receive your physical permit. If you fail, you cannot retake the test the same day.
