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.

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.

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.
