What You Need to Become a CDL Driver in Florida

A Commercial Driver's License (CDL) in Florida requires you to hold a valid regular driver's license first, pass a written knowledge test specific to the type of vehicle you'll operate, and pass a skills test that includes a pre-trip inspection, basic control, and an on-road driving exam. You must be at least 18 years old to drive a commercial vehicle within Florida, or 21 if you plan to drive across state lines. The Florida Department of Highway Safety and Motor Vehicles (DHSMV) administers all CDL testing and licensing.

The process takes several weeks from start to finish because you cannot take the skills test on the same day as your knowledge test. Most people spend 4 to 8 weeks preparing, testing, and waiting for their license to arrive by mail.

Key Takeaways

  • You must hold a valid Florida driver's license before you can test for a CDL, and you must be at least 18 years old (21 for interstate driving).
  • The knowledge test covers general CDL rules, air brakes, combination vehicles, or hazmat depending on the endorsement you need — you study the CDL manual and take the test at any DHSMV office.
  • The skills test happens at a separate appointment weeks later and includes a vehicle walk-around, basic control maneuvers, and a 45-minute road test with an examiner.
  • You must pass a medical examination by a certified Medical Examiner and provide the results to DHSMV before your CDL is issued.
  • Florida recognizes out-of-state CDLs for 30 days, but you must obtain a Florida CDL if you become a resident or work in the state.

CDL Classes and Endorsements in Florida

Florida issues three classes of CDL based on the vehicle's Gross Vehicle Weight Rating (GVWR) and cargo type. Class A covers combination vehicles (tractor-trailers) with a GVWR over 26,001 pounds where the towed unit exceeds 10,000 pounds. Class B covers single vehicles over 26,001 pounds GVWR or any vehicle towing a unit under 10,000 pounds. Class C covers vehicles under 26,001 pounds GVWR but requires an endorsement to carry passengers or hazardous materials.

Endorsements add to your CDL and allow you to operate specific vehicle types or carry certain cargo. The most common are Hazmat (H) for hazardous materials, Passenger (P) for buses or vans carrying 16 or more people, Tanker (N) for tank vehicles, and Double/Triple Trailers (T). You take a separate knowledge test for each endorsement you want, but the skills test covers only the vehicle class you're testing in.

Knowledge Test Requirements and Study Materials

The CDL knowledge test is written, multiple-choice, and taken at any DHSMV office. The general test has 50 questions and you must score at least 80 percent to pass. If you're testing for endorsements, you take additional tests — Hazmat has 30 questions, Passenger has 20 questions, and so on. You can take all your knowledge tests on the same day if you want multiple endorsements.

Florida provides the CDL Manual free on the DHSMV website. The manual covers vehicle inspection, safe driving practices, air brake systems, combination vehicles, hazmat regulations, and passenger transport rules depending on what you're studying for. You can also pick up a printed copy at any DHSMV office. Many people study for 2 to 4 weeks before testing, though the time varies based on your experience and how many endorsements you need.

You must bring a valid Florida driver's license and proof of Social Security number to the knowledge test. Bring your original Social Security card, a W-2, or a tax return as proof. You cannot use a cell phone or any reference materials during the test.

Skills Test: Vehicle Inspection, Control, and Road Exam

The skills test has three parts and must happen at least one day after you pass your knowledge test. You schedule it separately through DHSMV, and wait times vary by location — some offices have openings within 2 weeks, others take 6 to 8 weeks.

The pre-trip inspection requires you to walk around and point out critical components of the vehicle — lights, brakes, tires, mirrors, coupling devices, and safety equipment. You don't have to touch anything; you explain what you're checking and why. This portion lasts about 15 minutes.

The basic control test takes place in a closed course or lot and measures your ability to maneuver the vehicle. You perform tasks like backing in a straight line, backing into an offset alley, and parking between two lines. The examiner watches for smooth steering, proper mirror use, and control of the vehicle at low speed.

The on-road test lasts about 45 minutes and covers city driving, highway driving, and various traffic situations. The examiner sits beside you and scores your ability to control the vehicle, obey traffic laws, use mirrors, maintain safe speed, and respond to hazards. You must demonstrate smooth acceleration and braking, proper lane changes, and safe merging.

Medical Certification and DHSMV Requirements

Before DHSMV issues your CDL, you must pass a medical examination by a certified Medical Examiner listed on the National Registry of Certified Medical Examiners. The exam checks your vision, hearing, blood pressure, and general health to confirm you can safely operate a commercial vehicle. The cost ranges from $75 to $150 depending on the examiner.

You schedule the medical exam on your own and bring the completed form (MCSA-5875) to DHSMV when you submit your CDL paperwork. The medical certificate is valid for 24 months. If you fail the medical exam, you cannot proceed with your CDL until you address the medical issue and pass a new exam.

You must also disclose any traffic violations, accidents, or criminal convictions on your CDL process. Certain felonies and traffic offenses can disqualify you or delay your license. DHSMV conducts a background check as part of the process.

Fees, Timeline, and License Renewal

The CDL knowledge test costs $10 per test (so $10 for the general test, plus $10 for each endorsement). The skills test costs $30. The CDL license itself costs $48 for a four-year license or $72 for an eight-year license. Medical certification is separate and costs $75 to $150. Total out-of-pocket is roughly $150 to $250 depending on how many endorsements you pursue and which medical examiner you choose.

Your CDL is valid for four or eight years depending on which you choose at issuance. You renew by visiting a DHSMV office, passing a new medical exam, and paying the renewal fee. You do not retake the knowledge or skills test unless your license was suspended or revoked, or unless you want to add a new endorsement.

If you hold an out-of-state CDL and move to Florida or take a job in Florida, you have 30 days to obtain a Florida CDL. After 30 days, driving with an out-of-state license is illegal. To convert an out-of-state CDL, you take the Florida knowledge test and skills test just as a new applicant would.

Disqualifications and Restrictions

Certain convictions permanently disqualify you from holding a CDL. These include felonies involving controlled substances, crimes of violence, human trafficking, and sexual abuse. Other offenses like DUI, reckless driving, or leaving the scene of an accident trigger a one-year or three-year disqualification depending on the offense and whether it was your first violation.

If you accumulate too many traffic violations within a certain time period, your CDL can be suspended. Two serious violations within three years results in a 60-day suspension. Three serious violations within three years results in a 120-day suspension. A serious violation includes speeding 15 mph or more over the limit, improper lane changes, or following too closely.

You cannot hold a CDL if you have an active warrant, owe child support, or have unpaid traffic fines in Florida or any other state. DHSMV checks these records before issuing your license.

Frequently Asked Questions

Can I take the CDL knowledge test online or by mail?

No. The knowledge test must be taken in person at a DHSMV office. You cannot take it online, by mail, or at a third-party testing center. Walk in during office hours or schedule an appointment online through the DHSMV website to reduce wait times.

What happens if I fail the knowledge test or skills test?

If you fail the knowledge test, you can retake it the next day. If you fail the skills test, you must wait at least one week before scheduling another attempt. There is no limit to how many times you can retake either test, but you pay the fee each time.

Do I need a CDL to drive a pickup truck or small commercial vehicle?

Not always. If the vehicle's GVWR is 26,001 pounds or less and you're not carrying hazardous materials or passengers for hire, you do not need a CDL. Check your vehicle's registration or door placard for the GVWR. If you're unsure, contact DHSMV or your employer.

Can I get a CDL if I have a suspended or revoked driver's license?

No. Your regular Florida driver's license must be valid and in good standing. If your license is suspended or revoked, you must resolve the suspension first before you can test for a CDL.

How long does it take to receive my CDL in the mail after I pass the skills test?

DHSMV typically mails your CDL within 7 to 10 business days after you pass the skills test and submit all required documents, including your medical certification. You can drive with a temporary permit while you wait for the physical license to arrive.
