Florida CDL Class B Practice Test 2025

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.

Our Florida CDL Class B Practice Test can help you learn commercial driving theory efficiently. It includes an automated assistant, detailed explanations, and several features you can use to customize your testing experience. Once activated, the voice-over function can significantly increase your focus and retention rates. An artificial voice will read the questions and answer choices aloud, making it easier for you to pay attention in distracting environments.

To reflect the latest changes brought by DMV rules or state law, we have recently updated this practice test for October 2025. Because accuracy is important when studying commercial driving theory, you should also check the official Florida DMV website for the most up-to-date information.

You get unlimited attempts to train as often as you wish. After finishing a practice session, you can start another one right away. However, we recommend visiting your personal Challenge Bank™ first, as it includes helpful insight. This section automatically stores the questions you get wrong, so you can practice with them and learn from your mistakes.

Don’t wait for the perfect moment. Start your learning journey now and make each day count. As you practice more, your knowledge will naturally improve over time. With consistent practice, you’ll be ready to take the official general knowledge exam within a few weeks.
