DD stands for Developmental Disability, and it appears on your license as a notation that you have disclosed a developmental disability to your state's DMV
The DD marking is optional. You are not required to have it on your license, and requesting it does not change your driving privileges or legal rights. The purpose is to alert law enforcement and emergency responders that you may need additional communication support or patience during a traffic stop or roadside emergency. Some states call it DD; others use different codes like "DDA" or straightforward note it in the remarks section.
The marking itself carries no legal weight in court, does not restrict where you can drive, and does not affect insurance rates. It is purely informational for first responders. Whether to request it is your choice, and you can add it, remove it, or leave it off when you renew your license.

- Each state has different procedures for requesting the notation, and some states do not offer it at all.
- The DD marking has no effect on your insurance, your ability to drive, or how a court would treat you in a traffic case.
How to Request DD on Your License
The process varies by state. In most states that offer the option, you request it when you explore for a new license or renew an existing one. You will typically need to bring documentation of your disability diagnosis — this might be a letter from your physician, a copy of your Individualized Education Program (IEP) if you are school-age, or documentation from a disability services agency in your state.
Some states allow you to request DD by mail with your renewal process; others require you to appear in person at a DMV office. A few states let you request it over the phone or through an online portal. Contact your state's DMV directly to learn the exact procedure, because the rules differ significantly. You can usually find this information on your state DMV website under "special designations" or "medical conditions."
If you already have a license without the DD marking and want to add it, you do not have to wait for renewal. Most states allow you to request a replacement license with the new notation at any time, though there may be a small fee (typically $5 to $25 depending on the state).
What Documentation You Will Need
States do not have a single standard for what counts as proof of developmental disability. Common documents include a letter from a physician or psychiatrist stating your diagnosis, documentation from your state's developmental disabilities agency, school records showing an IEP or 504 plan, or a letter from a disability services provider. Some states accept only certain types of documentation; others are more flexible.
Before you gather documents, call your DMV or check their website to see what they will accept. Bringing the wrong paperwork means a wasted trip. If you are unsure whether your documentation qualifies, ask the DMV staff when you arrive — they can often tell you on the spot whether a letter or record meets their standard.
States That Offer DD and States That Do Not
Not all states offer a DD designation on the driver's license. States that do include California, Colorado, Florida, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nevada, New Mexico, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Texas, Virginia, Washington, and Wisconsin. However, this list changes, and some states may have added or removed the option since this was written.
If your state does not offer DD, you may be able to request a note in the "remarks" or "special conditions" section of your license, though this is not standardized. Your best option is to contact your state DMV directly and ask what options exist for documenting a disability on your license.
If you move to a state that does not offer DD, you will not be able to transfer the notation to your new license. You would need to request it again under that state's rules, if they offer it at all.
How Law Enforcement Uses the DD Marking
When an officer runs your license during a traffic stop, they will see the DD notation in their system. The intent is to give them context that you may communicate differently, may need more time to respond, or may become anxious during the interaction. This can help prevent misunderstandings and reduce tension.
The marking does not excuse you from traffic laws or give you special treatment in a legal sense. You can still receive a ticket, and you can still be arrested if you break the law. However, an officer who sees DD may be more patient, may speak more slowly, or may call for a supervisor or social worker if the situation becomes complicated. In an emergency, the notation alerts paramedics or hospital staff that you may need communication support.
The effectiveness of the DD marking depends on the officer and the situation. Some departments train their staff to recognize and respond appropriately to the notation; others do not. It is not a may provide of better treatment, but it is a tool that may help.
Removing DD From Your License
If you no longer want the DD marking on your license, you can request its removal at any time. You do not need new documentation or a reason. straightforward contact your DMV, request a replacement license without the notation, and follow your state's standard replacement process. There is usually a fee, the same as for any license replacement.
You can also straightforward leave it off when you renew your license. The DMV will not automatically carry over the DD marking to a new license — you have to request it each time. If you do not mention it during renewal, it will not appear on your new license.
Privacy and Disclosure Concerns
Some people choose not to request DD because they are concerned about privacy or worry that the marking could lead to discrimination. This is a valid concern. The notation is visible to any law enforcement officer who runs your license, and it becomes part of your driving record. If you are uncomfortable with that level of disclosure, you do not have to request it.
Others find that the potential benefit — better communication with first responders during a stressful situation — outweighs the privacy concern. The choice is entirely yours. There is no penalty for declining the DD marking, and you can change your mind later.
Frequently Asked Questions
Does DD on my license mean I cannot drive?
No. DD is a notation only; it does not restrict your driving privileges or change the rules of the road for you. You must still follow all traffic laws and pass the same driving test as anyone else. The marking is informational for law enforcement and emergency responders.
Will DD affect my car insurance rates?
No. Insurance companies do not have access to the DD notation on your license, and it does not factor into your rates. Your driving record, age, vehicle type, and claims history determine your premiums.
Can I request DD if I have a mental health condition instead of a developmental disability?
Most states that offer DD limit it to developmental disabilities — conditions present from birth or early childhood that affect intellectual functioning or adaptive behavior. Mental health conditions like depression or anxiety typically do not may have access to. Some states may have separate notations for other disabilities; contact your DMV to ask what options are available.
What happens if I move to another state — does my DD marking transfer?
No. When you get a license in a new state, you start fresh. If the new state offers DD and you want it, you will need to request it and provide documentation again under that state's rules.
Can I add DD to my license without telling anyone?
Yes. Requesting DD is between you and the DMV. You do not have to disclose it to your employer, your school, or anyone else. It appears only on your license and in law enforcement databases.
