What a Florida CDL is and who needs one
A Commercial Driver's License (CDL) in Florida is a special driving credential that allows you to operate certain large or hazardous vehicles for pay or as part of your job. You need a CDL to drive a truck weighing more than 26,001 pounds, a bus carrying 16 or more passengers, or any vehicle carrying hazardous materials — even if the vehicle itself is smaller.
Florida issues CDLs through the Department of Highway Safety and Motor Vehicles (DHSMV). The license comes in different classes (A, B, and C) depending on the vehicle weight and type, and you can add endorsements for specific cargo or driving situations, such as hazmat (H), tanker (N), or passenger (P) endorsements.
If you drive a regular passenger car or light truck for personal use, you do not need a CDL — your standard driver's license is sufficient. But if your job involves operating a commercial vehicle, Florida law requires you to hold a valid CDL before you get behind the wheel.
Key Takeaways
- Florida CDLs are issued by the DHSMV and required for driving trucks over 26,001 pounds, buses with 16+ passengers, or vehicles carrying hazardous materials.
- You must pass a written knowledge test, a skills test, and a medical examination before you can obtain a CDL for the first time.
- CDL renewals in Florida happen every four years and can be done in person at a DHSMV office or by mail if you meet certain conditions.
- Endorsements like hazmat (H), tanker (N), and passenger (P) require additional testing and background checks beyond the standard CDL.
- Failing the written or skills test means you must wait before retesting, and the waiting period depends on how many times you have already failed.
Getting your first Florida CDL: the three-step process
Obtaining a CDL in Florida involves three separate tests: a written knowledge test, a skills test, and a medical examination. You cannot skip any of them, and you must pass all three before the DHSMV will issue your license.
Start by scheduling an appointment at your local DHSMV office. Bring your current Florida driver's license, proof of Florida residency (such as a utility bill or lease), and your Social Security card or passport. You will also need to complete a Medical Examiner's Certificate (Form MCSA-5875) from a certified medical examiner; this certificate confirms you are physically fit to operate a commercial vehicle and is valid for 24 months.
At your appointment, you will take the written knowledge test first. The test covers traffic laws, vehicle inspection, safe driving practices, and any endorsements you are pursuing. You must score at least 80 percent to pass. If you fail, you can retake the test, but you must wait one day before your second attempt and seven days before any attempt after that.
Once you pass the written test, you schedule a separate appointment for the skills test. This test has three parts: a pre-trip vehicle inspection (where you walk around the truck and point out safety features), a basic control skills test (backing, turning, and parking), and a road test (driving on public roads). You must bring the commercial vehicle you will be driving during the test, and it must be properly registered and insured.
Medical certification and what disqualifies you
The medical examination is not optional — you cannot obtain or renew a CDL without a current Medical Examiner's Certificate. The exam checks your vision, hearing, blood pressure, and overall health. A certified medical examiner (not your regular doctor) must perform it, and you can find a list of approved examiners on the DHSMV website.
Certain medical conditions can disqualify you from holding a CDL. These include uncontrolled diabetes, heart disease, severe sleep apnea, epilepsy, and some psychiatric conditions. If you have a condition that might affect your ability to drive safely, the medical examiner will determine whether you can be certified. Some conditions allow certification with restrictions or a shorter certificate validity period.
Your Medical Examiner's Certificate is valid for 24 months. When it expires, you must obtain a new one before your CDL expires, or your license will no longer be valid for commercial driving. The DHSMV will send you a reminder, but it is your responsibility to schedule the exam in time.
CDL renewal in Florida: timing and your options
Florida CDLs expire every four years on your birthday. You will receive a renewal notice in the mail about 90 days before your license expires. Unlike standard driver's licenses, you cannot renew a CDL online — you must renew in person at a DHSMV office or by mail.
To renew in person, bring your current CDL, proof of residency, your Social Security card or passport, and a current Medical Examiner's Certificate. You will not retake the written or skills tests during renewal unless your CDL was suspended, revoked, or expired for more than one year. The in-person renewal takes about 30 minutes, and you can usually get your new license the same day.
If you cannot visit a DHSMV office, you may renew by mail if you meet these conditions: your CDL has not been suspended or revoked, it has not been expired for more than one year, you have not had any violations in the past two years, and you have a current Medical Examiner's Certificate. Mail renewal takes longer — typically two to three weeks — so plan ahead if your license is approaching expiration.
Adding endorsements to your CDL
An endorsement is an add-on to your CDL that allows you to drive certain types of vehicles or carry specific cargo. Florida offers several endorsements, each with its own requirements and testing.
The Hazmat (H) endorsement allows you to transport hazardous materials. To obtain it, you must pass a written test on hazmat regulations, pass a Transportation Security Administration (TSA) background check, and pay an additional fee. The TSA background check includes fingerprinting and a criminal history review. The hazmat endorsement is valid for five years, shorter than the standard CDL.
The Tanker (N) endorsement is required if you drive a vehicle with a tank larger than 119 gallons, even if it is not carrying hazardous materials. You must pass a written test on tanker-specific safety rules. The Passenger (P) endorsement is required if you drive a bus or van carrying 16 or more passengers. You must pass a written test and a skills test that includes passenger safety procedures.
Other endorsements include Double/Triple Trailers (T), Tank Vehicles (N), and School Bus (S). Each has its own written test and, in some cases, a skills component. You can add endorsements when you first obtain your CDL or at any time during the validity of your license.
Costs, documents, and what to bring to the DHSMV
The cost of a Florida CDL varies depending on whether you are obtaining it for the first time or renewing. A first-time CDL costs around $75 to $100, though the exact amount depends on the class and endorsements you are pursuing. Endorsements add extra fees — hazmat endorsements, for example, cost more because of the TSA background check. Renewal costs less than a first-time license, typically $50 to $75.
Medical Examiner's Certificates are not issued by the DHSMV; you pay the medical examiner directly, and costs vary by provider but usually range from $50 to $150. This fee is separate from your CDL fee.
For a first-time CDL, bring your current Florida driver's license, proof of Florida residency (utility bill, lease, or mortgage statement), your Social Security card or passport, and your completed Medical Examiner's Certificate. For renewal, bring your current CDL, proof of residency, your Social Security card or passport, and your current Medical Examiner's Certificate. If you are adding an endorsement, you may need to bring additional documents depending on the endorsement type.
What happens if you fail the written or skills test
If you fail the written knowledge test, you must wait one day before you can retake it. If you fail a second time, you must wait seven days before a third attempt. After three failures on the same test, you must wait two weeks before trying again. Each failure costs you another test fee.
If you fail the skills test, the waiting period is longer. You must wait two weeks before your first retest, and if you fail again, you must wait two weeks before each subsequent attempt. The skills test is more expensive than the written test because it requires an examiner and a commercial vehicle, so budget for multiple fees if you do not pass on your first try.
If you accumulate too many violations or convictions while holding a CDL, the DHSMV may suspend or revoke your license. A suspension is temporary; a revocation is permanent and requires you to reapply from the beginning, including retaking all tests.
Frequently Asked Questions
Can I get a Florida CDL if I have an out-of-state commercial license?
Yes, you can transfer an out-of-state CDL to Florida without retaking the written and skills tests, as long as your out-of-state license is valid and you pass Florida's knowledge test on state-specific rules. You must still obtain a Florida Medical Examiner's Certificate and bring your out-of-state CDL to the DHSMV office.
How long does it take to get a Florida CDL from start to finish?
The timeline depends on how quickly you schedule appointments and pass the tests. The written test can happen at your first appointment, but the skills test is scheduled separately and may take weeks to book. Most people complete the process in four to eight weeks, but it can take longer if you fail a test and must wait before retesting.
What if my Medical Examiner's Certificate expires before my CDL does?
Your CDL becomes invalid for commercial driving once your Medical Examiner's Certificate expires, even if your CDL itself has not expired yet. You must obtain a new certificate before you can legally operate a commercial vehicle. Schedule your medical exam before your current certificate expires to avoid a gap in your driving privileges.
Do I need a CDL to drive a pickup truck for work?
Not unless the truck weighs more than 26,001 pounds. Most pickup trucks weigh less than that, so a standard driver's license is sufficient. Check your vehicle's Gross Vehicle Weight Rating (GVWR) on the door jamb or registration to be sure.
Can I renew my Florida CDL online?
No, CDL renewals must be done in person at a DHSMV office or by mail. Online renewal is not available for commercial licenses. If you renew by mail, allow two to three weeks for processing.
