DD stands for "Developmental Disability" on a Texas driver's license
The DD designation on your Texas driver's license is a notation that tells law enforcement and other officials you have a documented developmental disability. It appears in the "Designation" field on the front of your license, usually in the lower left area. This marking does not change how you drive or what you are legally allowed to do on the road — it is purely informational.
The DD code exists so that if you are pulled over or involved in an accident, officers when ready know you may need different communication approaches or accommodations. It can also help in emergency situations, where first responders benefit from knowing about a disability upfront. The designation is optional: you can request it when you renew or replace your license, but you do not have to have it.
Key Takeaways
- DD on your Texas license means you have a documented developmental disability and have chosen to disclose it on your driver's license.
- The marking is visible to law enforcement during traffic stops and is used to alert officers that you may need accommodations in communication or interaction.
- You can request the DD designation when you renew your license, get a replacement, or visit a Texas Department of Public Safety office — it is not automatic.
- Having DD on your license does not restrict your driving privileges or change the rules of the road for you.
- You will need documentation of your developmental disability from a physician or may have access to professional to add the designation to your license.
How to request DD on your Texas driver's license
To add the DD designation to your license, you must visit a Texas Department of Public Safety (DPS) office in person. You cannot request it online or by mail. Bring your current driver's license or ID, proof of residency (such as a utility bill or lease), and medical documentation of your developmental disability from a licensed physician, psychiatrist, psychologist, or other may have access to healthcare provider.
The medical documentation does not need to be a formal letter — it can be a page from your medical records that states your diagnosis and confirms you have a developmental disability. The DPS office will review your documents and, if everything is in order, add the DD code to your license on the spot or issue you a new one with the designation included. There is no additional fee for adding this designation.
What counts as a developmental disability for the DD code
Texas defines a developmental disability as a substantial limitation in three or more areas of major life activity, with onset before age 22. These areas include self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, and economic self-sufficiency. Conditions that commonly may have access to include intellectual disability, cerebral palsy, autism spectrum disorder, and Down syndrome.
The specific diagnosis matters less than whether your condition meets the state's definition of substantial limitation. Your healthcare provider can tell you whether your diagnosis qualifies. If you are unsure, you can contact your local DPS office and ask what documentation they need to evaluate your situation.
Why you might want the DD designation on your license
The main reason to request DD on your license is to alert law enforcement during a traffic stop. Officers trained in disability awareness will recognize the code and may adjust how they communicate with you, ask you to step out of the vehicle, or conduct a sobriety test. This can prevent misunderstandings that might otherwise escalate a routine stop.
The designation can also help in medical emergencies. If you are in an accident or need emergency services, paramedics and hospital staff will see the notation and may take it into account when treating you or communicating with you. Some people also find it useful when interacting with other government agencies or in situations where disclosing a disability upfront prevents confusion later.
Why you might choose not to request DD on your license
Some people prefer not to have the DD designation visible on their license because it is a form of disclosure. Your driver's license is shown frequently — at traffic stops, when cashing checks, or when entering age-restricted venues — and the marking is visible to anyone who sees it. If you value privacy around your disability, you may decide the benefits of the notation do not outweigh the visibility.
There is no penalty for declining the DD designation, and you can change your mind at any time. If you have it on your current license and want it removed, you can visit a DPS office and request a new license without the code. The choice is entirely yours.
Renewing or replacing your license with DD
If you already have DD on your license and you renew it — whether online, by mail, or in person — the designation will carry over to your new license automatically. You do not need to provide the medical documentation again unless DPS specifically requests it.
If you lose your license and need a replacement, the DD code will still appear on your replacement license. If you want to add DD for the first time during a renewal or replacement, you will need to bring your medical documentation to a DPS office in person, since online and mail renewals do not allow you to add new designations.
Other designations you might see on a Texas driver's license
DD is one of several designations that can appear on a Texas license. Organ donor status appears as a heart symbol. Veteran status shows if you served in the military. Some licenses also carry Hazmat endorsements if you drive commercial vehicles carrying hazardous materials. Each designation serves a specific informational purpose and is requested separately.
If you have questions about any designation on your license or want to add or remove one, your local DPS office can walk you through the process. You can find office locations and hours on the Texas DPS website.
Frequently Asked Questions
Does DD on my license mean I cannot drive?
No. The DD designation does not restrict your driving privileges or change the rules of the road. You must still meet all the same requirements to hold a valid license, pass vision and written tests, and follow traffic laws. The code is informational only.
Can I request DD online or by mail?
No, you must visit a Texas DPS office in person to add the DD designation for the first time. Bring your current ID, proof of residency, and medical documentation of your developmental disability. Once it is on your license, it will carry over during future renewals.
What if my healthcare provider will not give me written documentation?
Contact your local DPS office and ask what forms of documentation they accept. Some offices will work with you if you have medical records on file elsewhere, or they may have a specific form your provider can complete. Do not assume a letter is required — ask first.
Can I remove DD from my license later?
Yes. Visit a DPS office and request a new license without the DD designation. There is no fee, and you do not need to provide any reason. You can add it back at any time if you change your mind.
Will having DD on my license affect my insurance or driving record?
No. Insurance companies and driving records do not reference the DD designation. It is visible only on the physical license itself and does not appear in any database that affects your rates or record.
