Imagine driving a heavy truck on Florida’s roads. You could be transporting pallets of bottled water from Jacksonville to Tampa, supplying stores ahead of hurricane season. The journey takes you across Interstate 10 and down Interstate 75, passing through busy traffic and crossing major highway interchanges. Managing the weight of your load, maintaining safe speeds, and staying alert to sudden weather changes would all be part of the job. Commercial driving involves great responsibility, and you must always drive responsibly.

Before you can get a Commercial Driver’s License (CDL), you must master the various aspects of commercial driving theory. This subject is thoroughly described in the official Florida Commercial Driver License Manual (Florida CDL Handbook 2025). You should read its contents at least once during your learning phase. A 50-question general knowledge test will evaluate your knowledge of this subject. You must score 80% or higher to pass, leaving little room for error.

Passed tests very easily.
I passed hree tests for the CDL: the general knowledge, air brakes, and combination vehicles. It took me 35 minutes to pass all three tests. It took me two days to read the manual and do all the practice tests that I bought from you guys. So, if you follow the instructions on driving-tests.org, it will be very easy to pass.

Did the general knowledge test and four endorsements.
I did the general knowledge test and four endorsements, and thanks to you guys, I passed them all with flying colors. Three of the tests I got zero wrong, and the other two, I got one wrong on the one and two wrong on the other, but other than that, pointers for those taking that test: make sure you read questions correctly—they're a little bit tricky there. But thanks for the good information you provide with your testing program.

The best study guide program I’ve ever used!
Even the FAA test prep programs I used to become a pilot weren’t as good as this. Very well structured you will definitely be ready after completing the program!

Just to let you know that I passed.
I passed just today all three parts of the CDL/Class A exam (General Knowledge, Brakes & Combinations/FDMV), having it taken me less than 40 minutes to complete. I have to say that your system is just excellent. When I sat in today, it was just a piece of cake, once I started taking the General Knowledge test, my confidence just started building. The personal at the Fdmv were surprised as well, for they told me that they had people taking the General Knowledge Part for months without passing it.

I passed.
I passed my CDL permit test in Florida using this subscription. Appreciate you guys. I will still subscribe to this site to teach myself the Pre trip inspection.

I passed 5 exams on the 1st try.
I had zero errors on 4 of the exams. So, I already have my CLP. I don't plan to do anymore work on the CDL until January because I am working for UPS delivering packages during their busy season. The problem I am having now is finding a place in Florida to take the driving part of the CDL. The state delegates that function to the CDL schools. I already know how to drive because I had a CDL until 4 years ago when I retired. But, everyone wants to charge me about,000 to take the driving test. The CDL training laws change on Feb 7th, but it does not effect me because I already have my CLP. The schools act like people have to get their CDL by Feb 7th but they really only need too get their CLP by then.

Excellent product.
It absolutely prepares you for taking the Florida CDL test. I took 4 of them, the basic, air, doubles and triples and tankers, I passed all on first try. DMV allows retaking for a small fee, but didn't need it. The different tests are setup perfectly, so if you miss a question, it'll come back at the end. Thank you!
