Texas DPS lists N as the endorsement authorizing tank vehicle operation on a CDL or CLP, and its handbook says qualifying liquid or gas cargo does not have to be hazardous. The handbook uses the more-than-119-gallon individual and 1,000-gallon aggregate tank threshold language for many Class A/B tank situations. Federal 49 CFR Part 383 requires tank applicants to know cargo surge, braking when empty/full/partial, baffled versus non-baffled handling, tank construction, product density, grades, curves, emergency systems, and DOT tank marking/retest concepts. Federal CDL knowledge tests require at least 80% correct.

Texas CDL Tanker Endorsement Test Study Tips from Top Performers
Frequently Asked Questions
What endorsement do I need to operate tank vehicles in Texas?
Texas DPS lists endorsement code N as authorizing operation of a tank vehicle on a CDL or CLP. Placarded hazardous materials in tanks require appropriate HazMat authority as well, generally reflected by X when both H and N apply.
What score is required to pass the Texas CDL tanker knowledge test?
Federal CDL testing regulation in 49 CFR §383.135 requires at least 80 percent correct on each knowledge test. Texas CDL testing is administered under those federal CDL standards.
Does the Texas tanker endorsement apply only to hazardous materials?
No. The Texas Commercial Motor Vehicle Drivers Handbook states that the liquid or gas does not have to be hazardous material. Hazardous cargo may add separate H or X requirements.
What tank capacity triggers the Texas tanker endorsement study rule?
The Texas handbook describes the tank endorsement for qualifying Class A or B CDL vehicles hauling liquid or liquid gas in tanks with individual rated capacity over 119 gallons and aggregate rated capacity of 1,000 gallons or more, permanently or temporarily attached to the vehicle or chassis. It also discusses Class C hazardous-material liquid or gas tank situations.
Is ELDT required for the Texas Tank Vehicles (N) endorsement alone?
FMCSA and Texas DPS ELDT guidance applies to first-time Class A/B CDL, certain upgrades, and first-time HazMat, passenger, or school bus endorsements. N alone is not listed as an ELDT endorsement trigger, although HazMat tank operations can require HazMat ELDT and TSA clearance.
What should I study for the Texas CDL tanker endorsement?
Study the Texas CMV Drivers Handbook Tank Vehicles section plus federal 49 CFR 383.119 topics: surge, braking when empty/full/partial, baffled versus non-baffled handling, tank construction, product density, grades and curves, emergency systems, marking/retest concepts, and safe operating procedures.
