About This Test

This course prepares you for the Tank Vehicle (N) endorsement knowledge test. It is for a driver who will haul liquids or gases in a tank of more than 119 gallons, with 1,000 gallons or more in total. The N endorsement needs a knowledge test only.

North Carolina gives the test at its own driver licensing office, and sets its own fees and required documents, so confirm those with the state before you go.

This course drills 50 questions on the federal rules that apply in every state and DC. A state may add rules of its own on top of the federal minimum.

Questions

Common Questions

Is there an official test, and how is the mock test scored?

80 percent is the federal pass mark for every CDL knowledge test (49 CFR 383.135). No federal rule sets the question count: 49 CFR 383.133 sends the states to AAMVA's test system, which is not public. The count here is the one used by the states that publish theirs, so your state may differ. 20 questions, 16 correct to pass.

How are the questions checked?

Every question is checked before it goes live, and again each time the site is updated.

Where do I take the CDL Tank Vehicle (N) test in North Carolina?

North Carolina gives the test at its own driver licensing office, and sets its own fees and required documents, so confirm those with the state before you go.
