NJ MVC lists the N endorsement for operators of vehicles transporting liquids or gas in bulk, and the NJ CDL Manual lists the tanker test as a 20-question endorsement test. MVC publishes an 80% passing score for CDL knowledge tests, a $125 CDL test fee, a seven-day wait after a failed knowledge test, and a 180-day Test Receipt renewal point. The tank endorsement can apply even when the liquid or gas is not hazardous, once the CDL class and tank-capacity thresholds are met. Federal Part 383 requires a tank vehicle knowledge test and defines the required tanker knowledge areas.

About the NJ CDL Tanker Exam
The New Jersey CDL Tanker Vehicles Endorsement Test is the NJ MVC knowledge test for drivers who need the N endorsement to operate qualifying tank vehicles transporting liquids or gases in bulk. The NJ CDL Manual covers the tank endorsement threshold, tank inspection, leak checks, valves, piping, hoses, manhole covers, vents, special equipment, high center of gravity, liquid surge, bulkheads, baffles, smooth bore tanks, outage, loading limits, curves, stopping distance, skids, and safe driving rules. Federal CDL rules in 49 CFR Part 383 require a tank vehicle knowledge test and specify knowledge areas including cargo surge, braking with empty/full/partially full tanks, baffled and non-baffled handling, tank construction, product density, grades, curves, emergency systems, and DOT specification tank retest/marking requirements.

Frequently Asked Questions
How many questions are on the New Jersey CDL tanker endorsement test?
The New Jersey CDL Manual lists the tanker test for hauling liquids or gases in bulk as 20 questions.
What score do I need to pass the New Jersey CDL tanker test?
NJ MVC states CDL knowledge tests require at least 80% correct. Federal CDL rules in 49 CFR 383.135 also use an 80% minimum for knowledge tests.
What does the N endorsement cover in New Jersey?
NJ MVC lists N as the Tank Vehicle endorsement, needed for operators of vehicles that transport liquids or gas in bulk.
Does tanker cargo have to be hazardous to require the N endorsement?
No. The NJ CDL Manual states the liquid or gas does not have to be hazardous when the tank vehicle endorsement threshold applies.
Is ELDT required just to add the N tanker endorsement?
FMCSA endorsement-specific ELDT requirements apply to first-time H, P, and S endorsements, not N alone. ELDT may still apply to a first-time Class A or Class B CDL applicant before the skills test.
What is the biggest handling topic on the tanker test?
Liquid surge is central: partially filled tanks can push the truck during braking or shift side-to-side in curves, increasing stopping-distance and rollover risk.
