DD stands for "Developmental Disability" and appears on your driver's license as a designation code
The letters DD on your driver's license indicate that you have disclosed a developmental disability to your state's Department of Motor Vehicles. This is not a diagnosis printed on your license — it is an internal code that appears in the DMV database and on your physical card in some states. The code alerts law enforcement, medical personnel, and other officials that you may need additional support or communication information during a traffic stop or emergency.
The DD designation is entirely voluntary. You choose whether to request it when you explore for or renew your license. Some states print it visibly on the front or back of the card; others record it only in their system. The specific placement and visibility depend on your state's DMV policies and the type of license you hold.

- You do not need a formal diagnosis or court order to request DD; most states require only a signed statement or form completed by you or your guardian.
- Removing the DD code is possible at any time by visiting your local DMV office or submitting a request form, depending on your state.
How DD appears on your license and what officers see
The way DD displays varies significantly by state. In some states — including California, Colorado, and New York — the code appears on the front or back of the physical card where anyone handling your license can see it. In other states, DD is recorded only in the DMV's internal database and does not print on the card itself. An officer running your license during a traffic stop will see the notation on their computer screen, but a person looking at your card in person will not.
When an officer pulls you over or responds to an incident involving you, the DD code appears in their dispatch system or on the screen they use to check your license status. This alerts them that you may have a developmental disability and may benefit from slower communication, more time to respond, or information from a caregiver or advocate. The code does not tell the officer what your specific disability is — only that one exists.
Who can request DD and what documentation you need
Most states do not require a formal medical diagnosis or court order to request DD on your license. Instead, you or your legal guardian can request it by completing a form at your local DMV office or submitting one by mail. Some states ask you to sign a statement confirming that you have a developmental disability; others ask your guardian or a healthcare provider to sign. A few states ask for documentation such as a letter from a doctor, school district, or disability services agency, but this is less common.
If you are a minor, your parent or legal guardian typically makes the request on your behalf. If you are an adult, you can request it yourself unless you have a court-appointed guardian, in which case your guardian may need to sign the form. Contact your state's DMV directly to learn what form to use and whether documentation is required in your state — requirements differ significantly.
States that display DD visibly versus those that keep it private
Whether DD appears on your physical card or stays in the DMV database only depends on your state's policy. Some states have chosen to print DD visibly on the front or back of the license card, while others keep it visible only to law enforcement through their computer systems. This distinction matters if you are concerned about privacy — a visible code means anyone who sees your license will know about the designation, while a database-only code is seen only by officers during official checks.

This table reflects general state practices as of the most recent update, but policies change and some states are transitioning between systems. Contact your state DMV to confirm whether DD will appear on your physical card or remain in the database only.
Why someone might request DD and what it does and does not do
People request DD for several reasons. During a traffic stop, the code alerts the officer that you may need extra time to understand instructions, may communicate differently, or may become anxious during the interaction. This can prevent misunderstandings and reduce the risk of escalation. In an emergency, paramedics or hospital staff can see the code and understand that you may need communication support or may have difficulty following standard procedures.
DD does not affect your driving privileges, your insurance rates, or your ability to renew your license. It does not appear on background checks for employment or housing. It is not a medical record and does not give the DMV authority over your healthcare decisions. It is purely an alert system for law enforcement and emergency responders. Some people choose not to request DD because they prefer privacy or because they do not want the code visible on their card. This is a personal choice, and there is no penalty for declining it. You can also request DD later if you change your mind — you do not have to decide at the time of your initial process.
How to request DD when explore for or renewing your license
The process depends on your state, but the general steps are:
- Contact your state DMV office or visit their website to find the form for requesting DD (often called a "Developmental Disability Designation Request" or similar).
- Complete the form yourself or have your guardian complete it, depending on your state's rules.
- Gather any required documentation — this varies by state but may include a letter from a doctor, school, or disability services provider.
- Submit the form in person at your local DMV office, by mail, or online if your state offers that option.
- If you are explore for a new license at the same time, you can often submit the DD request form together with your license process.
- If you already have a license, you can request DD at your next renewal or submit the form separately without renewing.
Processing times vary. Some states add the code to your record when ready; others take one to two weeks. If you are renewing your license and requesting DD at the same time, the new card with the code will arrive with your renewed license.
Removing or changing DD on your license
You can remove the DD code at any time by visiting your DMV office in person or submitting a written request, depending on your state. If you are a minor, your guardian can request removal. If you are an adult with a court-appointed guardian, your guardian may need to sign the removal request.
Removal is straightforward and does not require documentation or a reason. You straightforward tell the DMV you want the code removed, and they update your record. If DD is printed on your physical card, you will need to renew your license to receive a new card without the code, or some states allow you to request a replacement card when ready. If your circumstances change — for example, if you no longer have a developmental disability or no longer want the code for privacy reasons — contact your local DMV office to learn the removal process in your state.
