What you need to know before you start

A Commercial Driver's License (CDL) in Florida is issued by the Florida Department of Highway Safety and Motor Vehicles (DHSMV). It allows you to operate certain large or hazardous vehicles for pay. You cannot straightforward renew a regular driver's license and add a commercial endorsement — you must pass a separate written test, a skills test, and a medical examination. The entire process typically takes several weeks to a few months, depending on how quickly you schedule your tests and whether you need training first.

Florida recognizes three classes of CDL: Class A (tractor-trailers and other combinations over 26,001 pounds), Class B (single vehicles over 26,001 pounds), and Class C (smaller vehicles carrying hazardous materials or 16 or more passengers). Most people pursuing a CDL in Florida start with Class A or B. You will also need to decide which endorsements you want — such as Hazmat (hazardous materials), Tanker, or Passenger — because each one requires its own test.

Key Takeaways

  • You must hold a valid Florida driver's license before you can obtain a CDL, and you must pass a medical examination by a DHSMV-certified medical examiner.
  • The written test covers general knowledge, air brakes, and combination vehicles (for Class A), and you can take it at any DHSMV office without prior training.
  • The skills test — which includes a pre-trip inspection, basic control, and road test — is often easier to pass after attending a CDL training school, though it is not required by law.
  • You will pay separate fees for the written test, the skills test, and the license itself, totaling roughly $200 to $300 depending on which class and endorsements you choose.
  • Once you pass both tests, you can pick up your CDL at a DHSMV office, though some offices allow you to receive it by mail.

Medical certification and the first requirement

Before you take any test, you must obtain a medical certificate from a DHSMV-certified medical examiner. This is not your regular doctor — it must be someone on the DHSMV's list of approved examiners. The examiner checks your vision, hearing, blood pressure, and general health to may support you can safely operate a commercial vehicle. The certificate is valid for two years and must be in your possession when you take the written test.

You can find certified medical examiners on the DHSMV website or by calling your local DHSMV office. The exam typically costs $75 to $150 out of pocket. If you have a medical condition — such as diabetes, heart disease, or sleep apnea — the examiner may require additional documentation from your doctor, which can delay the process. Some conditions may disqualify you, so it is worth confirming with an examiner before paying for the full exam.

The written test: what to study and where to take it

The written test is administered at any DHSMV office and covers the rules and safety practices for commercial driving. For a Class A CDL, you will answer questions on three topics: general knowledge (50 questions), air brakes (25 questions), and combination vehicles (20 questions). For Class B, you take general knowledge and air brakes. Each section has a passing score of 80 percent. You can take the test without attending a training school, though many people study a CDL manual or take practice tests online to prepare.

The DHSMV publishes a free CDL handbook on its website that covers all test topics. You can read it, study it on your own, and schedule your test at any DHSMV office. The written test fee is typically $10 to $15 per test section. If you fail a section, you can retake it, but you must wait at least one day before trying again. Many people pass the written test on their first attempt if they study the handbook thoroughly.

The skills test and the role of training schools

After you pass the written test, you must pass a skills test administered by an DHSMV examiner or a third-party testing service. The skills test has three parts: a pre-trip inspection (you walk around the vehicle and point out safety features), basic control (you maneuver the vehicle in a controlled area), and a road test (you drive on public roads). The entire test takes about an hour and a half. You must bring a vehicle that matches the class of license you are testing for — you cannot borrow a friend's truck if it does not meet the requirements.

Many people attend a CDL training school before taking the skills test. These schools teach you how to operate the vehicle, how to pass the pre-trip inspection, and how to handle the road test. Training typically costs $3,000 to $7,000 and lasts two to eight weeks, depending on the school and whether you attend full-time or part-time. Training is not legally required, but it significantly increases your chances of passing the skills test on your first attempt. Some training schools also help you find a job after you pass.

If you choose not to attend a training school, you can still take the skills test, but you must have access to a suitable vehicle and someone who can supervise your practice. The skills test fee is typically $100 to $200, depending on whether you use an DHSMV examiner or a third-party tester.

Endorsements and additional tests

Once you have your Class A or B CDL, you can add endorsements that allow you to carry specific types of cargo or passengers. The most common endorsements are Hazmat (hazardous materials), Tanker (liquid cargo), Doubles/Triples (multiple trailers), and Passenger (16 or more people). Each endorsement requires a separate written test, and some require a skills test as well. Hazmat endorsement also requires a federal background check and fingerprinting through the Transportation Security Administration (TSA).

You can take endorsement tests at any DHSMV office. Each written test costs roughly $10 to $15. If you are pursuing Hazmat, budget an additional $85 to $100 for the TSA background check and fingerprinting, which is done at an approved location. Many people add endorsements after they have been driving commercially for a while, rather than all at once.

Timeline and fees at a glance

The timeline for obtaining a CDL in Florida depends on whether you attend training school. If you study on your own and already have a suitable vehicle, you can complete the written test within a few weeks. The skills test can often be scheduled within a month or two, depending on examiner availability in your area. If you attend a training school, add two to eight weeks to the timeline.

Here is a rough breakdown of costs: medical certificate ($75–$150), written test fees ($30–$45 for all sections), skills test ($100–$200), and the CDL license itself ($75–$100). If you attend training school, add $3,000 to $7,000. If you pursue Hazmat endorsement, add $85–$100. Total out-of-pocket cost without training ranges from $280 to $495; with training, expect $3,500 to $7,500 or more.

Frequently Asked Questions

Do I need a regular driver's license first?

Yes. You must hold a valid Florida driver's license before you can obtain a CDL. Your CDL will replace your regular license, not add to it, so make sure your regular license is current and in good standing.

Can I take the written test without attending a training school?

Yes. The written test is open to anyone with a valid driver's license and a medical certificate. You can study the free CDL handbook from the DHSMV website and take the test at any DHSMV office. Many people pass without formal training.

What happens if I fail the skills test?

You can retake the skills test, but you must wait at least one day. You pay the test fee again each time you retake it. Many people who fail the first time attend a training school or practice more before trying again.

How long is a CDL valid in Florida?

A CDL is valid for eight years, the same as a regular driver's license. Your medical certificate must be renewed every two years, so you will need to visit a certified medical examiner before your certificate expires, even if your CDL is still valid.

Can I get a CDL if I have a criminal record?

Most criminal records do not automatically disqualify you, but certain convictions — particularly felonies involving drugs or violence — may prevent you from obtaining a CDL or certain endorsements like Hazmat. Contact the DHSMV directly to discuss your specific situation.
