Florida CDL Handbook

Florida issues the Tank Vehicles (N) endorsement to CDL drivers who pass the required written test and will drive tank vehicles. The Florida CDL handbook says the tank endorsement applies to qualifying Class A or B CDL vehicles carrying liquid or gas in tanks over 119 gallons each and 1,000 gallons aggregate, whether permanently or temporarily attached; Class C hazmat liquid/gas tank situations can also require it. Federal rules require at least 80% on CDL knowledge tests and 49 CFR 383.119 defines tanker knowledge areas. FLHSMV lists a $7 endorsement fee, $10 knowledge retest fee, and $75 original/renewal CDL fee.

About the FL CDL Tanker Exam

The Florida CDL Tanker Vehicles Endorsement Test is the written knowledge test for drivers seeking the Tank Vehicles (N) endorsement on a Florida commercial driver license. It is based on FLHSMV CDL requirements, Florida CDL handbook Section 8, FMCSA tank-vehicle guidance, and 49 CFR Part 383. The tested knowledge includes tank inspection, manhole covers, vents, valves, special equipment, liquid surge, outage, baffles, bulkheads, smooth bore tanks, high center of gravity, braking, curves, grades, emergency systems, DOT tank marking/retest concepts, and Florida endorsement context.

Assessment

Florida administers the Tank Vehicles (N) written CDL endorsement knowledge test. Official FLHSMV pages reviewed do not publish a separate public item count for the Florida tanker test; 20 is used here as a common endorsement practice format while logistics identify the official-source limitation.

Time Limit

Set by FLHSMV testing administration; no separate public tanker time limit found in official sources reviewed

FL CDL Tanker Study Tips from Top Performers

1Memorize the Florida endorsement context: N is Tank Vehicles, H is Placarded Hazmat, and X combines hazmat and tanker authority.
2Use Florida CDL handbook Section 8 as the primary content outline: inspection, driving tank vehicles, and safe driving rules.
3Know the capacity threshold language: tanks over 119 gallons each and 1,000 gallons aggregate for qualifying Class A/B operations, including temporarily attached tanks.
4Treat partial loads as high risk because they allow liquid surge; slow early, brake smoothly, and leave extra following distance.
5Separate baffles from bulkheads: baffles have holes and reduce forward/back surge; bulkheads divide compartments and make weight distribution critical.
6Never forget outage: liquids expand as they warm, and different liquids expand by different amounts.
7For inspection questions, think containment first: manhole covers, gaskets, vents, valves, leaks, hoses, emergency shut-offs, and required equipment.

Frequently Asked Questions

What endorsement do I need to drive tank vehicles in Florida?

FLHSMV lists Tank Vehicles as the N endorsement. It is issued to drivers who pass the required written test and will drive tank vehicles. Placarded Hazmat and Tank Vehicles together are reflected by the X endorsement when the driver qualifies for both H and N.

What score do I need to pass the Florida CDL tanker knowledge test?

Federal CDL testing regulation in 49 CFR 383.135 requires at least 80 percent correct on each CDL knowledge test. Florida CDL testing must meet that federal minimum standard.

How much does the Florida tanker endorsement cost?

FLHSMV lists endorsements at $7.00, knowledge retests at $10.00, and an original or renewal Commercial Driver License at $75.00. A tax collector service fee may apply to some credential transactions.

What should I study for the Florida CDL Tanker test?

Study Florida CDL handbook Section 8, Tank Vehicles. Focus on inspection, special equipment, surge, outage, baffles, bulkheads, smooth bore tanks, weight distribution, braking, curves, grades, and emergency systems. Also review FLHSMV CDL endorsement rules and 49 CFR 383.119.

Does the tanker endorsement apply only to hazardous materials?

No. The Florida CDL handbook states the liquid or gas does not have to be hazardous material for the tank endorsement requirement to apply. Hazardous materials may require a separate Hazmat endorsement and, for placarded hazmat tank vehicles, X endorsement authority.

What is liquid surge?

Liquid surge is the movement of liquid cargo inside the tank. It is strongest with partial loads and can push the truck during braking or shift weight sideways in turns, increasing stopping distance and rollover risk.

What is outage or ullage?

Outage, also called ullage, is the empty space left in a cargo tank for liquid expansion. The Florida CDL handbook says never to load a cargo tank totally full because liquids expand as they warm.
