The Florida CDL knowledge test is a commercial driving regulations assessment. You must pass this test to get a Commercial Learner's Permit (CLP) which is required before you can take the skills test for a full CDL. The test covers CMV operation, safety regulations, traffic laws and safe operating procedures. It's taken electronically at FLHSMV offices throughout Florida. Questions cover both federal regulations and Florida specific rules, so you'll have the knowledge to operate commercial motor vehicles in Florida and across state lines if applicable.

You need to take the test if you're:

• Getting your first CLP
• Adding a new endorsement
• Upgrading your CDL class (from Class B to Class A for example)
• Reinstating an expired CDL (over one year)
• Transferring a CDL from another state with new endorsements

All applicants must take the general knowledge test plus additional tests for specific endorsements like Passenger (P), School Bus (S), Tank Vehicles (N), Hazmat (H), or Doubles/Triples (T). Each endorsement has its own test for that vehicle or cargo type.

The test ensures commercial drivers have the necessary knowledge to operate CMVs safely. It verifies understanding of regulations, safety practices, technical knowledge and emergency procedures. This helps maintain safety standards and reduces accident risks on public roads. Commercial motor vehicles can cause significant damage in accidents because of their size and weight, so proper knowledge and training is essential before operating these vehicles. The knowledge test is the first step in making sure you're ready for the responsibility of commercial driving.

The test follows Federal Motor Carrier Safety Administration standards with Florida specific regulations added. This ensures national consistency in commercial driver qualifications while addressing state specific requirements. Topics covered include general operating skills, air brake operations, combination vehicles and specific endorsements. So your Florida CDL will be recognized throughout the United States, you can operate CMVs across state lines (as long as you meet age and other qualifications for interstate commerce).

• General Knowledge: 50 questions
• Air Brakes: 25 questions
• Combination Vehicles: 20 questions
• Passenger Endorsement: 20 questions
• School Bus Endorsement: 20 questions
• Hazmat Endorsement: 30 questions
• Tank Vehicles Endorsement: 20 questions
• Doubles/Triples Endorsement: 20 questions

The questions are multiple choice with 4 possible answers for each question. The tests thoroughly cover safety procedures, regulations and technical aspects of commercial motor vehicles.

Sample question: During your pre-trip inspection you notice a brake hose that appears to be worn. What should you do?

• Continue your trip but have it checked at your next scheduled maintenance
• Note it on your inspection report but continue your trip
• Apply more pressure when using the brakes
• Do not drive the vehicle until the hose is replaced

Answer: D. Do not drive the vehicle until the hose is replaced.

You must answer 80% of questions correctly on each test:

• General Knowledge: 40/50
• Air Brakes: 20/25
• Combination Vehicles: 16/20
• Passenger Endorsement: 16/20
• School Bus Endorsement: 16/20
• Hazmat Endorsement: 24/30
• Tank Vehicles Endorsement: 16/20
• Doubles/Triples Endorsement: 16/20

Each test is scored separately and you must pass each one individually. If you fail one test but pass others, you'll only need to retest the failed test.

The test is only in English. Federal regulations require commercial drivers to read and speak English sufficiently to understand traffic signs, communicate with officials, complete records and understand shipping documents. This ensures all commercial drivers can safely navigate roadways, communicate with law enforcement and emergency services, and properly handle documentation. There are no exceptions to this language requirement for CDL testing in Florida.

No. You cannot use notes, electronic devices, reference materials or calculators during the test. Testing areas are monitored and using prohibited materials will result in test failure. All personal items must be stored in a designated area during testing. This includes:

• Cell phones and electronic devices
• Notes or cheat sheets
• Commercial Driver License manuals
• Reference materials of any kind
• Calculators (unless specifically authorized for certain questions)

Using prohibited materials during testing could result in immediate disqualification and may affect your ability to test again in the future.

There is no time limit, but most applicants complete the general knowledge test in 60-90 minutes. Most endorsement tests take 30-45 minutes each. Plan accordingly if taking multiple tests in one visit. The FLHSMV provides sufficient time to complete the tests without rushing. If you have documented learning disabilities or other special needs, accommodations may be available with proper documentation.

Some locations may accept walk-ins for CDL assessments, but wait times can be very long and you may not be able to test that day if capacity is reached. Scheduling an appointment ensures you'll be evaluated at your preferred time and location.

No. All CDL knowledge assessments must be taken in person at authorized FLHSMV offices to ensure security, identity verification and examination integrity. This is a federal requirement that applies to all states, not just Florida. In-person testing prevents cheating and ensures the person receiving the CDL is the one who demonstrated the knowledge.

Required documents:

• Valid Florida driver's license (Class E)
• Social Security card/number
• Proof of citizenship/legal residency (birth certificate, passport, permanent resident card, etc.)
• Proof of Florida residency (two documents showing your Florida address)
• Current DOT Medical Certificate (Form MCSA-5876)
• Completed CDL application
• Payment for applicable fees (cash, check or credit card)
• For Hazardous Materials: Additional identification documents for security threat assessment

Other:

• Reading glasses if needed
• Appointment confirmation

Arrive 15-20 minutes early to allow time for:

• Document verification
• Application processing
• Fee payment
• Getting settled before the assessment begins

If you arrive late, you may have to reschedule. First-time applicants should arrive 30 minutes early to allow time for paperwork processing. Traffic and parking at FLHSMV offices can be unpredictable, so plan accordingly.

You'll receive a Commercial Learner's Permit (CLP) valid for 12 months with these conditions:

• Must wait at least 14 days before taking the skills assessment
• Can only operate a CMV with a qualified CDL holder in the passenger seat
• No passengers except supervisors, trainees or examiners
• No hazardous materials transport
• Other restrictions based on vehicle type/endorsements

Specific endorsements you passed assessments for will be included on your CLP.

Practice operating commercial motor vehicles while supervised before taking your skills assessment. This practice time is important to develop the skills needed to pass the behind-the-wheel test.

Scores are valid for 12 months, same as your CLP. If your CLP expires before you complete the skills assessment, you'll need to retest all knowledge exams. There are no extensions on score validity, so plan to complete your skills test within the 12-month window to avoid having to retest. This ensures your knowledge is current when you get your full CDL.

If you fail:

• Wait until the next business day to retest
• Only retest the sections you failed
• Use our practice tests to focus on weak areas
• Review incorrect answers to understand why they were wrong
• Consider studying with different methods if you're struggling with particular topics

There's no limit to how many times you can retest, but repeated failures may mean you need more preparation. The retesting fee in Florida is $10 for written exams.

Sample question: If you're involved in an accident while carrying hazardous materials, what should you do first?

• Call your supervisor immediately
• Protect yourself and others from the hazardous materials
• Begin cleaning up any spilled materials
• Try to move your vehicle out of traffic

Answer: B. Protect yourself and others from the hazardous materials.

After holding your CLP for at least 14 days:

• Go to GoRenew.com or call (850) 617-2000
• Make sure your CLP is valid and medical certificate is current
• Arrange for a test vehicle that matches your CDL class
• Pay the skills test fee ($75 for all license classes in Florida)
