The F endorsement test checks whether you can safely operate a school bus or other passenger vehicle carrying 16 or more people
The F endorsement is a classification added to your driver's license that permits you to drive vehicles designed to carry 16 or more passengers, including school buses. The test itself has two parts: a written knowledge exam and a behind-the-wheel driving test. Both are administered by your state's Department of Motor Vehicles or equivalent agency.
The written exam covers passenger safety procedures, vehicle inspection, emergency protocols, and the specific handling characteristics of large buses. The driving test takes place in an actual bus or similar vehicle and evaluates your ability to perform basic maneuvers, manage the vehicle's size and weight, and respond to simulated hazards. You must pass both components to receive the endorsement.
Requirements and test content vary by state, but all states follow federal guidelines set by the Commercial Driver's License (CDL) program. Some states require you to hold a commercial driver's license (CDL) before adding an F endorsement; others allow you to add it to a standard license. Check your state's DMV website for the specific rules in your jurisdiction.
Key Takeaways
- The F endorsement permits you to legally operate buses and large passenger vehicles carrying 16 or more people.
- The test includes a written knowledge section covering safety, inspection, and emergency procedures, plus a practical driving component in an actual bus.
- Both parts must be passed; passing only the written exam does not grant the endorsement.
- Requirements and test procedures differ by state, so you should review your state DMV's specific rules before scheduling.
- Many states require a CDL before you can add an F endorsement, while others allow it on a standard license.
What the Written Knowledge Test Covers
The written portion typically includes 50 to 70 multiple-choice questions drawn from a study manual provided by your state's DMV. Topics include passenger loading and unloading procedures, wheelchair securement, emergency evacuation routes, and how to inspect the bus before operation.
You will also be tested on how to handle specific scenarios: what to do if a passenger becomes ill, how to respond to a mechanical failure while driving, and how to manage aggressive or disruptive passengers. The exam emphasizes safety over technical knowledge—the goal is to confirm you understand the unique responsibilities of carrying many people at once.
Most states require a score of 80 percent or higher to pass. You are usually allowed to retake the test if you do not pass on your first attempt, though some states impose a waiting period between attempts. Study materials are free and available through your state DMV's website or office.
The Behind-the-Wheel Driving Test
The practical test is conducted in a full-size bus or, in some states, a vehicle that simulates bus dimensions and handling. An examiner rides with you and scores your performance on a standardized rubric. The test typically lasts 30 to 45 minutes and includes both off-road maneuvers and on-road driving.
Off-road portions usually involve backing in a straight line, backing into a space, and performing a lane-change maneuver. These test your ability to judge the vehicle's size and position. On-road portions involve normal driving on public streets, including turns, stops, and responses to traffic signals and other vehicles.
The examiner is looking for smooth steering inputs, proper mirror checks, safe speed management, and correct use of signals and brakes. Common reasons for failing include hitting cones or barriers during maneuvers, failing to check mirrors, unsafe lane changes, and improper responses to traffic. You must demonstrate that you can operate the vehicle safely and predictably.
State Variations in Testing Requirements
While all states follow federal CDL guidelines, the specific structure of the F endorsement test varies. Some states require you to hold a CDL Class B (bus) license before adding an F endorsement; others allow you to add it to a standard Class D license. A few states do not use the F designation at all and instead classify passenger vehicles under different rules.
Testing fees range from roughly $50 to $150 for the written exam and $100 to $300 for the driving test, depending on your state. Some states bundle these into a single fee; others charge separately. A handful of states offer the written test online, while most require you to take it in person at an office.
The study materials and testing locations are listed on your state's DMV website. Before you schedule, confirm whether your state requires a CDL first, what the current fee structure is, and whether you need to bring any documents (such as proof of residency or your current license).
Preparing for the Written Exam
Your state DMV provides a free study guide that covers all topics on the written test. This guide is the primary resource you should use; questions on the actual exam are drawn directly from it. Most guides are available as PDFs on the DMV website or as printed copies at any DMV office.
The study guide typically includes sample questions with explanations, diagrams of bus components, and step-by-step procedures for common tasks like pre-trip inspection and passenger loading. Reading through it once takes two to four hours. Many people find it helpful to read it twice and take practice tests online if your state offers them.
Common weak areas include the specific steps for wheelchair securement, the proper sequence for a pre-trip inspection, and the rules for passenger conduct and emergency evacuation. If you have professional bus driving experience, you may find the material familiar, but even experienced drivers should review the study guide because test questions focus on specific procedures and terminology.
Preparing for the Driving Test
The best preparation is hands-on practice in a bus or similar large vehicle. If you are already employed as a bus driver or have access to a bus through your employer, ask your supervisor or training department whether you can practice the specific maneuvers tested. Many school districts and transit agencies offer practice sessions for employees preparing for the F endorsement.
If you do not have access to a bus, some private driving schools offer F endorsement preparation courses that include classroom instruction and practice time in a bus. These courses typically cost $300 to $800 and last one to three days. They are optional but can be valuable if you have limited driving experience or are nervous about the test.
Focus your practice on the maneuvers that will be tested: straight-line backing, backing into a space, and lane changes. These require judgment about the vehicle's size and position, which is different from driving a car. Practice checking mirrors frequently, making smooth steering inputs, and maintaining control at low speeds.
What Happens After You Pass
Once you pass both the written and driving tests, your state DMV will add the F endorsement to your license. This usually happens within one to two weeks. Your new license will be mailed to you, or you may be able to pick it up at a DMV office depending on your state's procedures.
The F endorsement does not expire on a different schedule than your regular license; it renews at the same time. Some states require you to pass a medical examination (similar to a CDL medical certificate) before adding an F endorsement, and you may need to renew that certificate periodically. Check your state's rules about medical requirements.
Once you have the endorsement, you are legally permitted to operate any bus or passenger vehicle designed for 16 or more people. Your employer may have additional training or certification requirements beyond the state test, so confirm what your specific job requires before you start driving.
Frequently Asked Questions
Do I need a commercial driver's license to get an F endorsement?
It depends on your state. Some states require a CDL Class B before you can add an F endorsement; others allow you to add it to a standard license. A few states have different classifications entirely. Check your state DMV website to confirm the requirement in your jurisdiction.
How many times can I retake the written test if I fail?
Most states allow unlimited retakes, but some impose a waiting period (usually 7 to 14 days) between attempts. A few states limit the number of retakes within a certain time frame. Your state DMV can tell you the specific rules when you register for the test.
Can I use my personal vehicle for the driving test?
No. The driving test must be conducted in a bus or vehicle that meets the size and weight specifications for the endorsement. Your testing location will provide the vehicle or tell you where to bring one if you are supplying it yourself.
What if I fail the driving test?
You can retake it after a waiting period set by your state, usually 7 to 14 days. There is typically a fee for each attempt. Most people pass on the second or third try after additional practice. Your examiner will provide feedback on what you need to improve.
Does the F endorsement allow me to drive any large vehicle?
No. The F endorsement is specifically for vehicles designed to carry 16 or more passengers. It does not permit you to drive large trucks, RVs, or other commercial vehicles. Those require different endorsements (such as the A, B, or C endorsements on a CDL).
