What an F Endorsement Covers and Why You Need It

An F endorsement on a commercial driver's license authorizes you to operate a bus designed to carry 16 or more passengers, including the driver. This is the passenger endorsement specific to buses — not to be confused with the P endorsement, which covers small buses and vans carrying 16 or more people but with a lower GVWR threshold. If you drive a full-size transit bus, school bus, or motorcoach for a carrier, you need the F endorsement.

The F endorsement requires passing a written knowledge test and a skills test (road test) in addition to holding a valid CDL. You must also pass a medical examination and meet federal and state background requirements. The process typically takes several weeks from start to finish, depending on how quickly your state's DMV schedules your tests.

Some states bundle the F endorsement with other passenger endorsements or require you to hold a P endorsement first; check your state's specific rules before you begin. The cost varies by state but typically ranges from $10 to $50 for the endorsement itself, plus test fees.

Key Takeaways

  • You must hold a valid CDL in your state before you can add an F endorsement; you cannot test for the F endorsement alone.
  • The F endorsement requires passing a written knowledge test covering passenger safety, emergency procedures, and vehicle operation, plus a separate skills test in an actual bus.
  • You must pass a Department of Transportation (DOT) medical examination and obtain a valid medical certificate before you can be issued the endorsement.
  • Some states require you to hold a P endorsement (small bus) before testing for an F endorsement, so verify your state's sequence before scheduling tests.
  • The entire process — from medical exam to final endorsement — usually takes 4 to 8 weeks depending on test availability and processing time.

Step-by-Step Process to Add an F Endorsement

Step 1: Verify you hold a valid CDL. You must already have a commercial driver's license in your state. If you do not, you will need to obtain your CDL first by passing the general knowledge test, air brake test (if applicable), and combination vehicle test, plus a skills test. The F endorsement is an addition to an existing CDL, not a standalone license.

Step 2: Schedule and pass a DOT medical examination. Contact a certified medical examiner on your state's FMCSA (Federal Motor Carrier Safety Administration) registry. You will need to complete the Medical Examination Report (Form MCSA-5875) and provide proof of vision, hearing, and general health. The examiner will issue you a Medical Certificate valid for 24 months. You must have this certificate before you can test for the F endorsement. Bring the original certificate to your DMV appointment.

Step 3: Study for the F endorsement knowledge test. Obtain your state's CDL manual or the FMCSA's Commercial Driver's License Manual. Focus on the passenger transport section, which covers boarding and disembarking procedures, emergency equipment, passenger communication, and vehicle safety checks specific to buses. Many states offer practice tests online through their DMV website.

Step 4: Schedule and pass the written knowledge test. Visit your state's DMV website or call your local office to book a test appointment. The test typically has 20 to 30 questions and covers passenger safety, emergency procedures, and bus operation. You must score at least 80% to pass. Bring your valid CDL, medical certificate, and state-issued ID.

Step 5: Schedule and pass the skills test. After passing the written test, you will need to schedule a road test in an actual bus. The examiner will evaluate your pre-trip inspection, basic control skills, and on-road driving. You must demonstrate safe passenger handling, proper mirror checks, and smooth acceleration and braking. The test usually takes 45 minutes to an hour.

Step 6: Submit your paperwork and receive your endorsement. Once you pass both tests, return to the DMV with your passing test scores, medical certificate, and any required state forms. Pay the endorsement fee (typically $10 to $50) and your F endorsement will be added to your CDL. Your new license will be mailed to you or issued on the spot, depending on your state.

Medical Certificate Requirements and Timeline

The DOT medical examination is a hard requirement and cannot be skipped. You must complete it before you sit for the F endorsement knowledge test in most states. The examination covers vision (at least 20/40 in each eye, corrected or uncorrected), hearing, blood pressure, and a general health history. If you have certain medical conditions — such as diabetes, heart disease, or sleep apnea — you may need additional documentation or specialist clearance.

The medical certificate is valid for 24 months from the date of issue. If your certificate expires before you complete your F endorsement tests, you will need to renew it before you can finish the process. Plan your medical exam at least 6 to 8 weeks before you want to test, to allow time for any follow-up appointments if the examiner flags a concern.

Finding a certified medical examiner can take time. Use the FMCSA National Registry of Certified Medical Examiners (available at fmcsa.dot.gov) to search by state and zip code. Call ahead to confirm availability and ask about wait times; some examiners book weeks in advance. The exam itself costs between $75 and $150, depending on the examiner and your location.

State-Specific Differences in F Endorsement Rules

Not all states handle the F endorsement the same way. Some states require you to hold a P endorsement (small bus) before you can test for an F endorsement. Others allow you to test for the F endorsement directly if you already hold a CDL. A few states combine the P and F endorsements into a single passenger endorsement. Check your state's CDL manual or contact your DMV before you schedule any tests.

Test fees, medical certificate requirements, and the number of questions on the written test also vary. Some states charge a flat fee for all endorsements; others charge per endorsement. A few states allow you to take the written test online, while most require an in-person visit to a DMV office. Call your state's CDL program office or visit the DMV website to confirm the exact process, fees, and required documents for your state.

Processing time for the final endorsement also differs. Some states issue the endorsement when ready after you pass both tests; others mail it within 1 to 2 weeks. If you need the endorsement quickly for a job start date, ask your DMV whether expedited processing is available and what it costs.

Common Mistakes to Avoid When Testing for an F Endorsement

Mistake 1: Not obtaining the medical certificate first. Many people schedule their knowledge test before they have a valid medical certificate. Even if you pass the written test, you cannot receive the endorsement without the certificate. Get the medical exam done first, then schedule your tests.

Mistake 2: Confusing the F endorsement with the P endorsement. The P endorsement covers buses with a GVWR of 10,001 pounds or more but designed to carry 16 or more passengers. The F endorsement covers full-size buses. If you are unsure which one you need, ask your employer or check the vehicle's registration and manufacturer specifications.

Mistake 3: Not studying the passenger-specific material. The F endorsement test focuses heavily on passenger safety, emergency procedures, and communication. Generic CDL study materials may not cover these topics in enough detail. Use the passenger section of your state's CDL manual and take practice tests that focus on the F endorsement specifically.

Mistake 4: Failing the pre-trip inspection during the skills test. Examiners expect you to perform a thorough pre-trip inspection of the bus, including checking mirrors, lights, brakes, emergency equipment, and passenger seating. Skipping or rushing this part is a common reason for test failure. Practice the inspection routine before your test date.

Mistake 5: Not confirming your state's sequence of endorsements. If your state requires the P endorsement before the F endorsement, attempting to test for the F endorsement first will result in rejection. Call your DMV to confirm the correct order.

What Happens After You Receive Your F Endorsement

Once your F endorsement is issued, it appears on your CDL alongside any other endorsements you hold. You are now legally authorized to operate a bus designed to carry 16 or more passengers. Your employer may require additional training or orientation specific to their fleet, but the F endorsement itself is the legal requirement.

Your F endorsement remains valid as long as your CDL is valid and your medical certificate does not expire. You must renew your medical certificate every 24 months; if it lapses, your F endorsement becomes invalid until you obtain a new certificate. Some states allow you to renew your medical certificate up to 90 days before it expires, so plan ahead.

If you move to another state, your F endorsement transfers with your CDL, but you may need to obtain a new medical certificate from a certified examiner in your new state if your current one is about to expire or if your new state has different medical standards. Check with your new state's DMV to confirm the process.

Frequently Asked Questions

Do I need a P endorsement before I can get an F endorsement?

It depends on your state. Some states require the P endorsement first; others allow you to test for the F endorsement directly if you hold a valid CDL. Check your state's CDL manual or call your DMV to confirm the sequence. If your state requires the P endorsement first, you will need to pass that test before scheduling your F endorsement test.

Can I take the F endorsement knowledge test online?

Most states require you to take the written test in person at a DMV office, but a few allow online testing. Contact your state's CDL program office or check the DMV website to confirm whether online testing is available in your state. Even if the written test is online, the skills test must be taken in person in an actual bus.

What if I fail the F endorsement skills test?

You can retake the skills test after a waiting period, which varies by state (typically 7 to 14 days). You do not need to retake the written test unless your state requires it. Review the areas where you struggled — usually pre-trip inspection, mirror checks, or passenger safety procedures — and practice before your next attempt.

How long is the F endorsement valid?

The F endorsement itself is valid as long as your CDL is valid. However, your medical certificate must be renewed every 24 months. If your medical certificate expires, your F endorsement becomes invalid until you obtain a new certificate. Plan to renew your medical certificate before it expires to avoid a lapse in your authorization to drive.

Can I add an F endorsement if I have a suspended or revoked license?

No. You must hold a valid, unrestricted CDL to add an F endorsement. If your license is suspended or revoked, you must resolve that issue first. Once your license is restored and valid, you can then test for the F endorsement.
