DD stands for "Developmental Disability" on a Texas driver's license

The DD designation on your Texas driver's license indicates that you have a documented developmental disability. The Texas Department of Public Safety (DPS) adds this notation at your request during the license process or renewal process. It is not automatically assigned — you must provide medical documentation and ask for it to be included.

The purpose of the DD marker is practical: it alerts law enforcement and emergency responders that you have a developmental disability before they interact with you. This can change how officers communicate with you during a traffic stop or emergency and may prompt them to call for additional support or a guardian if needed. The notation itself does not restrict your driving privileges or appear on any public record — it is visible only to you, the officer who pulls you over, and DPS staff.

Key Takeaways

  • DD on your Texas license means you have a documented developmental disability and requested the notation during process or renewal.
  • You must provide medical documentation from a physician or psychologist to add the DD marker to your license.
  • The notation is visible only to law enforcement, emergency responders, and DPS — it does not appear on background checks or public records.
  • Adding DD to your license does not change your driving privileges, but it alerts officers to communicate differently during interactions.
  • You can request the DD notation be removed at any time by visiting a DPS office with updated documentation or a written request.

How to request DD on your Texas driver's license

To add the DD notation, you must visit a Texas DPS driver's license office in person. You cannot request it by mail or online. Bring a completed DL-43 form (process for Texas Driver's License or ID Certificate), a valid form of identification, and proof of residency. You will also need medical documentation — a letter from a licensed physician, psychiatrist, or psychologist stating that you have a developmental disability.

The medical documentation does not need to be recent, but it must clearly state the diagnosis. Some offices accept letters dated within the past five years; others may accept older documentation if it is still relevant. Call your local DPS office before you go to confirm what they will accept. The process typically takes 15 to 30 minutes, and you will receive your new license with the DD notation within 7 to 10 business days.

What counts as a developmental disability for the DD marker

Texas defines developmental disability broadly to include intellectual disability, cerebral palsy, autism spectrum disorder, and other neurological conditions that began before age 22 and are expected to continue indefinitely. The condition must substantially limit at least two major life activities — such as self-care, learning, working, or independent living.

The specific diagnosis matters less than the documentation. Your physician or psychologist must state in writing that you have a condition meeting this definition. If you are unsure whether your condition qualifies, contact your local DPS office or ask your healthcare provider whether they would describe your condition as a developmental disability.

What the DD marker does and does not do

The DD notation does alert law enforcement that you have a developmental disability. An officer who runs your license during a traffic stop will see the marker and may adjust how they communicate with you — speaking more slowly, asking yes-or-no questions, or calling for a supervisor or social worker. In an emergency, it signals that you may need additional support or that a guardian should be contacted.

The DD marker does not restrict your driving. It does not limit the type of vehicle you can drive, the hours you can drive, or any other aspect of your license. It does not appear on background checks, employment records, or any document outside of law enforcement and DPS systems. It is not visible to insurance companies, landlords, or the general public.

Removing the DD notation from your license

You can request removal of the DD marker at any time by visiting a DPS office. You do not need a reason, and you do not need new medical documentation — straightforward tell the staff member you want the notation removed. If you prefer, you can submit a written request by mail to your local DPS office, though visiting in person is faster.

Some people add the DD marker for a period of time and then remove it later. Others keep it permanently. The choice is entirely yours, and you can change your mind at any point in the future. There is no penalty for adding or removing the notation.

Where to find your local Texas DPS office

You can locate the nearest driver's license office by visiting the Texas DPS website and using their office locator tool. Search by city or zip code to find hours, address, and phone number. Many offices now use an online appointment system, which can reduce wait times. Call ahead to confirm they have the medical documentation you plan to bring and to ask any questions about the process.

Some smaller towns do not have a dedicated DPS office, so you may need to travel to the nearest city. Rural counties sometimes have a mobile unit that visits on specific days — the DPS website will show the schedule if one serves your area.

Frequently Asked Questions

Will adding DD to my license affect my car insurance rates?

No. Insurance companies do not have access to the DD notation on your license. Your rates depend on your driving record, age, vehicle type, and coverage choices — not on any medical information in the DPS system.

Can I add DD to my license if I have a learner's permit?

Yes. The process is the same whether you hold a learner's permit, regular driver's license, or ID card. Bring the same documentation to your local DPS office and request the notation be added.

What if I do not have a letter from my doctor saying I have a developmental disability?

Contact your physician, psychiatrist, or psychologist and ask them to write a letter stating your diagnosis and that it meets the definition of a developmental disability. If you do not have a current healthcare provider, you may need to schedule an appointment first. Some community health centers offer low-cost evaluations if cost is a barrier.

Does the DD marker show up when I renew my license?

Yes. Once you add the DD notation, it will remain on your license through renewals unless you request it be removed. You do not need to provide medical documentation again at renewal — the notation carries forward automatically.

Can someone else request DD on my license without my permission?

No. Only you or your legal guardian can request the notation. You must be present at the DPS office (or your guardian must be present on your behalf) and sign the process form.
