Free FL CDL Double/Triple Trailers 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 March 2025
Did you know that in Florida, you cannot tow more than one trailer or vehicle unless it’s for commercial purposes and you have obtained the Double/Triple Trailers endorsement? In fact, even if you obtain the Florida Double/Triple Trailers Endorsement, triple trailers are not allowed on Florida’s public roads. But make no mistake! Your marketability as a driver is greatly enhanced in the state of Florida when you can transport larger double trailer payloads, particularly in the agriculture, logistics, and freight industries.
If you’re in the market for this endorsement on your FloridaCDL, the key requirement is passing a 20-question multiple-choice knowledge test. The test requires a score of 80% (or 16 correct answers) to pass. Once you’ve achieved this certification, you receive the valuable “T” endorsement on your CDL, which authorizes you to pull two or three trailers (where such laws allow) and operate combination vehicles that require this added skill and knowledge (Florida CDL Handbook 2025).
You may be saying to yourself, “That sounds great! But how can I best prepare for this test?”
What you need is a systematic and focused approach. That’s where our online free Florida CDL Double/Triple Trailers practice test comes in. It is up to date as of March 2025 and includes 20 multiple-choice questions that resemble what you will face at the DMV on your actual test day!
As you take our online practice test, you’ll receive immediate, detailed feedback on each answer. If you select an incorrect response, we instantly show you why a different choice is correct, helping reinforce your understanding in real time. This way, you can absorb the material as you progress, rather than being bombarded with corrections at the end of the assessment.
The state of Florida only requires the passing of this knowledge test in order to add the “T” endorsement to your already existing Class A or Class B CDL. Once you have prepared, passed our free practice tests, and feel ready to go, you simply apply at the DMV, provide the required documentation, and pay the required fee prior to taking the official test.
