What the Course Entails and Exam Details

Preparing for the North Dakota CDL Tanker Endorsement involves mastering the specific safety protocols and operational techniques unique to tanker vehicles.

The core topics covered in your study materials and the official knowledge test include:

• Understanding Liquid Surge: Learning how the movement of liquid inside the tank affects braking and handling, and how to manage these forces.

• Safe Driving Rules: Adjusting speed for curves, maintaining proper following distance, and understanding the increased risk of rollovers.

• Bulkheads and Baffled Tanks: Identifying the different types of tanks and understanding how internal compartments affect liquid movement.

• Proper Inspection Procedures: Specifically checking for leaks, verifying the integrity of valves, hoses, and manhole covers before and after trips.

• Emergency Maneuvers: Techniques for safely responding to hazards and avoiding skids or rollovers when baffled or unbaffled.

What to Expect in the Final Exam

The North Dakota CDL Tanker Endorsement exam is a computerized knowledge test, not a skills test.

You can expect the following format at the North Dakota Department of Transportation (NDDOT) testing center:

• Format: Multiple-choice questions based entirely on the Tanker section of the North Dakota CDL Manual.

• Number of Questions: Typically consists of approximately 20 to 30 questions.

• Passing Score: You must achieve a score of at least 80% to pass (e.g., answering at least 16 out of 20 questions correctly).

• Time Limit: While usually not strictly timed, drivers are expected to complete the test within a reasonable timeframe.

• Prerequisites: You must already hold a valid North Dakota CDL or be in the process of obtaining one (passing the general knowledge test first).
