Free FL CDL Tanker Vehicles Practice Test 2025

  • Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements
  • Based on 2025 FL commercial driver's license manual
  • Triple-checked for accuracy
  • Updated for August 2025

Florida relies heavily on tanker trucks to transport essential commodities such as fuel, chemicals, and liquid food products from major ports like Miami and Everglades. Its road network is extensive, with major highways such as Interstate 95 and Interstate 75 playing a crucial role in freight movement. Commercial drivers often carry hazardous materials like gasoline and liquid chemicals on these roads, which can be an extremely dangerous but necessary endeavor during hurricane seasons.

The demand for commercial drivers with a Tanker (N) endorsement is quite high in the Sunshine State. A career in this field can be rewarding, but you must fully master this subject. It includes specific details unique to tankers, such as managing liquid surge, loading and unloading procedures and even emergency responses to leaks and spills.

To obtain a tanker endorsement on your Commercial Driver’s License (CDL), you must pass a written knowledge test that evaluates your understanding of safely operating tankers. If you haven’t yet done so for your CDL, you must also pass a skills test where you’ll prove your ability to safely handle a commercial vehicle of the license class you are applying for.

The Florida Department of Highway Safety and Motor Vehicles (FLHSMV) publishes the official 2025 CDL Manual (Florida CDL Handbook 2025). While this manual offers essential information on various aspects of commercial driving, it is only a piece of the puzzle that completes the big picture you’re looking for. Changing your perspective lets you develop a smarter approach while you are still in the learning phase. Students often encounter difficulties in studying the complex material presented in this manual, but there are more convenient alternatives available online.

Designed to closely resemble the official written exam, our Florida DMV CDL Tanker Endorsement practice tests have helped countless students obtain a passing score on their first attempt. Consisting of 20 questions on the Tanker endorsement, these practice tests can also be used as an educational tool. The lack of a timer allows you to take notes, search through the CDL manual and even ask our automated assistant for hints before you select an answer.
