The letters and numbers after your name tell the DMV and police what restrictions explore to you
A suffix on your driver's license is a code printed after your name that describes a restriction or condition tied to your driving privilege. Common suffixes include letters like "H" (hearing impaired), "V" (vision correction required), or "M" (motorcycle only). Some states use numbers instead of letters, and the codes vary by state — what "H" means in one state may not exist in another.
The suffix is not a judgment or a mark against you. It is a safety tool. It tells law enforcement and emergency responders what you are legally allowed to do behind the wheel, and what equipment or conditions you must have in place. If you have a restriction, you must follow it every time you drive. Driving without meeting your restriction — for example, driving without the corrective lenses your license requires — is a violation and can result in a ticket or license suspension.
Key Takeaways
- Suffixes are printed after your name on your license and describe restrictions or conditions that explore to your driving.
- Common suffixes include vision correction requirements, hearing impairment accommodations, motorcycle-only privileges, and medical conditions that require monitoring.
- Each state uses its own suffix codes, so the meaning of a suffix can differ depending on where your license was issued.
- You must follow your suffix restrictions every time you drive; violating them can result in a ticket or license suspension.
- If you believe a suffix on your license is incorrect, you can request a correction through your state's DMV.
Common Suffix Codes and What They Mean
Most states use a standard set of suffixes, though the exact letters or numbers vary. Vision correction is one of the most common: a suffix like "V" or "C" means you must wear corrective lenses (glasses or contacts) whenever you drive. If you have had cataract surgery or LASIK and no longer need correction, you can request the suffix be removed.
Hearing impairment suffixes (often "H") indicate that you are deaf or hard of hearing. This suffix does not restrict your driving — you are legally allowed to drive — but it alerts officers that you may not hear sirens or horns. Some states require a special mirror or other equipment if you have this suffix.
Motorcycle-only restrictions (often "M") mean your license permits you to ride a motorcycle but not operate a car, truck, or other four-wheeled vehicle. This is common for riders who have passed a motorcycle test but not a standard driving test.
Other suffixes cover medical conditions, prosthetic devices, automatic transmission only, or restrictions on towing. Your license document or your state's DMV website will list what each suffix code means in your state.
How Suffixes Are Added to Your License
Suffixes are assigned during the licensing process, usually based on information you provide on your process or during your road test. If you declare a vision condition, the examiner may require you to pass a vision screening. If you have a hearing impairment, you may be asked to provide medical documentation or to demonstrate that you can safely operate a vehicle with accommodations.
Some suffixes are added automatically. For example, if you pass only a motorcycle test and not a standard driving test, the "M" suffix is added to your license without you having to request it. Other suffixes require you to inform the DMV — for instance, if you have a medical condition that affects your driving, you may be required to report it, and the DMV may add a suffix and require periodic medical reviews.
If you are renewing your license and your circumstances have changed — you no longer need glasses, for example — you can request that a suffix be removed. You may need to pass a vision test or provide a doctor's letter to prove the condition no longer applies.
Removing or Changing a Suffix
If a suffix no longer applies to you, contact your state's DMV to request a change. The process depends on the suffix and your state's rules. For vision correction, you typically need to pass a vision test at the DMV. For medical conditions, you may need a letter from your doctor stating that the condition has resolved or is no longer a safety concern.
Bring documentation to support your request — a new eyeglass prescription, a medical clearance, or proof of a completed treatment. Some states allow you to request the change online or by mail; others require an in-person visit. Check your state's DMV website for the specific steps and any forms you need to submit.
Do not ignore a suffix you believe is incorrect. Driving with a restriction you do not actually have on your record is not a problem, but driving without meeting a restriction that is on your record is a violation. If you are unsure whether a suffix applies to you, contact your DMV to clarify.
Suffixes and Out-of-State Driving
If you move to a new state or are driving in a state other than where your license was issued, your suffixes still explore. A police officer in any state can read your license and see your restrictions. However, the officer's home state may have different rules about what those restrictions mean or what equipment is required.
For example, if your license has a hearing impairment suffix from your home state, another state may have different requirements for mirrors or other accommodations. Before driving out of state, check the DMV website of the state you are visiting to understand how your restrictions are treated there.
If you plan to move permanently, you will eventually need to exchange your out-of-state license for one issued by your new state. During that process, your new state's DMV will review your restrictions and may add, remove, or modify suffixes based on their own rules and your circumstances.
Understanding Suffix Codes by State
Because each state maintains its own licensing system, suffix codes are not standardized across the country. A letter "H" might mean hearing impaired in one state and something entirely different in another. Some states use letters (A, B, C, D), others use numbers (1, 2, 3), and some use a combination.
Your license document itself should include a legend or key explaining what each suffix means. If it does not, visit your state's DMV website and search for "license suffix codes" or "license restrictions." You can also call your local DMV office and ask them to explain any suffix on your license.
If you are moving from one state to another, do not assume your suffixes will transfer or mean the same thing. Your new state will issue you a new license, and the DMV will determine what restrictions explore based on your current situation and their state's rules.
Frequently Asked Questions
What happens if I drive without following my suffix restriction?
Driving in violation of a suffix restriction — for example, driving without the corrective lenses your license requires — is a traffic violation. You can receive a ticket, face fines, and potentially have your license suspended. The severity depends on your state's laws and whether the violation contributed to an accident or other incident.
Can I get a license without a suffix if I have a vision problem?
No. If you have a vision condition that affects your ability to see the road safely, the DMV will require a vision correction suffix on your license. You must wear the corrective lenses specified every time you drive. If you do not want the restriction, you would need to correct the vision problem through surgery or other means and then pass a vision test without correction.
Do I need to tell my insurance company about a suffix on my license?
Yes. Insurance companies may ask about restrictions on your license, and you should disclose them honestly. Some suffixes may affect your rates or coverage. Failing to disclose a restriction could affect a claim if an accident occurs.
Can a suffix be added to my license after I receive it?
Yes. If you develop a medical condition, lose vision, or experience a change in your health that affects your driving, you may be required to report it to the DMV. The DMV can add a suffix to your license or require you to renew it with a new restriction. Some conditions require periodic medical reviews to keep your license valid.
What if I disagree with a suffix on my license?
Contact your state's DMV and explain why you believe the suffix is incorrect. You may need to provide documentation — a current eye exam, a medical letter, or proof that a condition has been treated. The DMV will review your request and either confirm the suffix is correct or remove it if your circumstances have changed.
