ND CDL Tanker Vehicles Endorsement Practice Test 2025
- Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
- Based on 2025 ND commercial driver's license manual
- Triple-checked for accuracy
- Updated for August 2025
Tanker drivers provide essential transportation services, delivering many products that support community infrastructures. Are your driving opportunities in Grand Forks leaving you stuck in a muck of unsatisfactory pay and unreasonable working conditions? Consider adding a tanker endorsement to your North Dakota DOT Commercial Driver’s License (CDL). There is no shortage of employers needing tanker drivers, and you can qualify for the attractive benefits they’re offering. However, you must first get the training to best train you in tanker operations.
Our North Dakota DOT CDL tanker endorsement practice test is expertly designed to stimulate your thought processes while learning about tanker operations. You must meet a few requirements to get a tanker endorsement, including passing an official knowledge test. The practice test is presented in a simulated testing environment that mimics the actual testing experience. Unlike the official knowledge test, the practice test is untimed to let you work at your own pace under stress-free conditions. You must correctly answer 80% of the 20 questions on the official knowledge test to receive a passing score. The practice test uses 20 questions to assess your current proficiency level and identify your most challenging topics. It establishes a clear starting point for enhancing your skill level.
This North Dakota DOT CDL endorsement practice test supports your skill development with reliable and authoritative information. The practice test is based on the most recent North Dakota DOT CDL manual (North Dakota CDL Handbook 2025) and is up to date as of August 2025. If you submit an incorrect answer, the practice test provides a detailed explanation of the correct one. The practice test fully equips you to meet the challenges of the official knowledge test by showing you how to apply this information to various driving scenarios. You need to learn this information because it will be used in your daily driving practices. Depending on other on-line resources, such as study guides, to provide this instruction is not a practical approach. Study guides train you to memorize the answers to the questions. Your learning is limited to surface knowledge and doesn’t fully prepare you to exhibit the skills required to operate a tanker. You are more likely to become stalled in your progress and frustrated in your inability to overcome your learning obstacles. Using the practice test, you will be thoroughly prepared to pass the official knowledge test on your first try.
In addition to the tanker endorsement, a Hazardous Materials (HazMat) endorsement will further expand your driving opportunities. Our HazMat endorsement practice test is at https://driving-tests.org/north-dakota/nd-cdl-hazmat-practice-test/. It will help you learn the rules and regulations for transporting hazardous materials, such as flammable liquids and explosives.
