Drivers from other states might expect Florida’s nice weather and relatively flat terrain to make driving easy and safe. But residents of the state know that’s not always true. Rapid growth has increased traffic congestion on numerous roads, and heavy rainstorms can be treacherous. Here are a few examples: Congestion combined with a lack of barriers between lanes has given Interstate 4 the state’s highest traffic death rate per mile. Interstate 75 also has heavy traffic congestion. Also, fog or heavy rains can sharply limit visibility, and those rainstorms can increase the chance of hydroplaning. U.S. Route 1 has sharp curves, some narrow stretches, a lack of barriers, and flooding during storms.

Before facing such challenging driving conditions, you want to be sure your vehicle is up to the job. For this reason alone, you should conduct a pre-trip inspection of your commercial motor vehicle (CMV) before you drive it on Florida’s public roads.

Passing the official General Knowledge test is one of the key requirements to obtain a Commercial Learner’s Permit (CLP). You must obtain a CLP before you can become eligible for a Commercial Driver’s License (CDL). Your General Knowledge test will likely include some questions on pre-trip inspections, including identifying defects or faults in a vehicle’s components and systems. All questions on the General Knowledge test are based on the official Florida CDL manual (Florida CDL Handbook 2025). You should study the manual, but you should do more to be sure of passing the General Knowledge Test. Namely, you should reinforce your knowledge with our practice tests.

This CDL practice test is the first of our Florida CDL Pre-Trip Inspection Practice Tests. It’s a great way to prepare to answer the questions on pre-trip inspections in the General Knowledge test.

Like the official General Knowledge test, this practice test is multiple choice. Each question comes with several answer options. You must choose the best or most complete answer. As you try each question, our AI assistant can help you learn by supplying hints and answering your own questions about commercial driving theory. If you still miss a question, the AI assistant will immediately let you know and provide an explanation of the correct answer.

After you get your CDL, conduct a thorough pre-trip inspection of your CMV before driving it. Federal regulation 49 CFR § 392.7 requires you to be satisfied that all these vehicle components and systems are in good working order before you drive it: brakes, coupling devices (if so equipped), emergency equipment, horn, lights and reflectors, mirrors, steering gear, tires, wheels and rims, and windshield wipers.
