What an F endorsement is and why you might need one
An F endorsement on your Tennessee driver's license allows you to operate a motorized bicycle — sometimes called a moped or motorized pedal cycle — on public roads. The state defines this as a bicycle with an engine of 50 cubic centimeters or less and a top speed not exceeding 30 miles per hour. Without this endorsement, you cannot legally ride one, even if you own the vehicle.
You need an F endorsement before you ride. Tennessee law treats motorized bicycles differently from regular bicycles and from motorcycles, so the rules are specific. The endorsement itself is added to your existing driver's license; you do not get a separate document.
If you already hold a valid Tennessee driver's license in any class, you can add an F endorsement without taking a full written test or road test. The process is simpler than getting a motorcycle endorsement, but you still have to meet certain requirements and pass a knowledge test focused on motorized bicycle rules.
Key Takeaways
- You must hold a valid Tennessee driver's license before you can add an F endorsement.
- You will take a written test at the DMV covering motorized bicycle operation and safety, but not a road test.
- You must be at least 16 years old and provide proof of identity and residency to add the endorsement.
- The fee for adding an F endorsement is typically under $20, though the exact amount may vary by location.
- Once approved, the F endorsement is printed on your renewed or replacement license.
Who can get an F endorsement
To add an F endorsement to your Tennessee license, you must be at least 16 years old and already hold a valid Tennessee driver's license. You cannot get an F endorsement on its own — it is always added to an existing license class.
If you do not yet have a Tennessee driver's license, you will need to obtain one first through the standard process for your age group. Minors under 18 follow different rules than adults, including supervised driving requirements, so check with your local DMV office about the timeline if you are under 18.
There is no vision test or medical examination required specifically for the F endorsement. Your existing license already confirms you meet the basic requirements to drive on Tennessee roads.
Documents you need to bring to the DMV
Bring your current Tennessee driver's license and one form of government-issued photo identification. A passport, military ID, or state ID card all work. You will also need to show proof of Tennessee residency — a utility bill, lease agreement, or bank statement with your current address typically satisfies this requirement.
Some DMV offices may ask for your Social Security number or a copy of your Social Security card. Call your local DMV office before you go to confirm what they need, since requirements can vary slightly between locations.
You do not need to bring the motorized bicycle itself or any registration documents for it. The endorsement is about your license, not about registering the vehicle.
The written test for the F endorsement
The F endorsement test is a written exam administered at your local DMV office. It covers Tennessee laws specific to motorized bicycles, safe operation, and road rules that explore to them. The test is typically 20 to 30 questions, and you usually need to score 80 percent or higher to pass.
Study materials are available from the Tennessee Department of Safety and Homeland Security website. You can read the motorized bicycle section of the Tennessee Driver Handbook, which covers the rules you will be tested on. Topics include speed limits for motorized bicycles, where you can and cannot ride them, helmet requirements, and how to signal turns.
You take the test on a computer at the DMV office. There is no road test or practical demonstration required for the F endorsement, unlike a motorcycle endorsement. If you do not pass on your first attempt, you can retake the test after a waiting period — ask the DMV staff how long you must wait before trying again.
Helmet and safety requirements
Tennessee law requires anyone operating a motorized bicycle to wear a helmet that meets federal safety standards. This is a legal requirement, not just a safety recommendation. You must wear the helmet every time you ride, regardless of distance or speed.
The helmet must be approved by the Department of Transportation (DOT). Most helmets sold at bike shops, motorcycle shops, or online retailers carry this certification. Check the inside of the helmet for a DOT sticker or label.
Even though the helmet requirement is law, the DMV does not check whether you own one before issuing the endorsement. However, riding without a helmet is a violation and can result in a fine. Some insurance companies also offer discounts if you wear a helmet, so it is worth doing regardless of the legal requirement.
Where motorized bicycles can and cannot be ridden
In Tennessee, motorized bicycles are allowed on most public roads, but there are restrictions. You cannot ride on interstate highways, limited-access highways, or roads posted with "no motorized bicycles" signs. Some cities and counties have additional local rules, so check with your city or county before riding in unfamiliar areas.
Motorized bicycles are generally not allowed on sidewalks, pedestrian paths, or bike paths unless local ordinance specifically permits them. Many communities restrict them to roadways only. If you are unsure whether a particular path or road allows motorized bicycles, contact your local city or county transportation department.
Speed limits for motorized bicycles are typically the same as for regular traffic on that road. Even though your motorized bicycle may not be capable of going faster than 30 miles per hour, you still must obey posted speed limits and traffic signals.
Registration and insurance for motorized bicycles
Tennessee does not require motorized bicycles to be registered with the state, unlike motorcycles or cars. You do not need to obtain a title or registration document for the vehicle itself. The F endorsement on your driver's license is what allows you to operate one legally.
Insurance is not legally required for motorized bicycles in Tennessee, though some insurance companies offer optional coverage. If you already have homeowner's or renter's insurance, your motorized bicycle may be covered under that policy. Check with your insurance agent to see what is included and whether you want to add coverage.
Even without a legal requirement, insurance can protect you if you cause damage or injury while riding. The cost is usually low, and it can save you from significant out-of-pocket expenses if an accident occurs.
Frequently Asked Questions
Can I get an F endorsement if I have an out-of-state driver's license?
No. You must have a valid Tennessee driver's license to add an F endorsement. If you hold a license from another state, you will need to transfer it to Tennessee first. Contact your local DMV office for information about the transfer process, which typically requires proof of residency and identity.
What happens if I ride a motorized bicycle without an F endorsement?
Operating a motorized bicycle without the proper endorsement is a violation of Tennessee law. You can be cited and fined. The amount varies, but it is typically a traffic violation. You may also be required to stop riding until you obtain the endorsement.
Is there an age limit for the F endorsement?
You must be at least 16 years old. There is no upper age limit. If you are under 18, you may have additional restrictions on when and where you can ride, depending on your license class and any court-ordered restrictions.
Do I need to renew the F endorsement separately?
No. The F endorsement renews automatically when you renew your driver's license. You do not need to retake the test or pay a separate fee at renewal time. The endorsement will appear on your new license as long as you maintain a valid Tennessee driver's license.
Can I add an F endorsement online or by mail?
No. You must visit a DMV office in person to take the written test and add the endorsement to your license. You cannot complete this process online or through the mail.
