DD stands for Developmentally Disabled, and it's a voluntary notation the DMV can add to your driver's license if you have a documented developmental disability

The DD marking tells law enforcement and emergency responders that you have a developmental disability. It does not change your driving privileges, your testing requirements, or your ability to renew your license. It is purely informational — a way to alert first responders to your condition if you are stopped or involved in an accident.

Whether to request a DD designation is your choice. Some people find it useful because it can prompt officers to communicate more carefully or call for additional support if needed. Others prefer not to have it visible on their ID. There is no penalty either way, and you can request it added or removed when you renew.

Who qualifies for a DD designation

A developmental disability is a condition that began before age 22 and affects your ability to function in everyday life. Common examples include Down syndrome, cerebral palsy, autism spectrum disorder, and intellectual disabilities. The condition must be documented by a medical professional, psychologist, or developmental specialist.

You do not need to have a specific diagnosis to request DD. What matters is that a may have access to professional has assessed you and confirmed that you have a developmental disability. Your doctor, psychiatrist, or a state disability agency can provide this documentation.

How to request DD on your license

Contact your state's DMV and ask about adding a DD notation to your driver's license. Most states allow you to request this during a renewal, but many also let you add it between renewals by visiting in person or submitting a form by mail.

You will need to bring or submit medical documentation that confirms your developmental disability. This is usually a letter from your doctor, a psychological evaluation, or a letter from your state's disability services agency. The DMV will tell you what form of proof they accept when you call or visit.

Some states have a specific form you fill out to request the notation. Others straightforward note it in their system when you provide the documentation. Ask your DMV whether you need to complete a form or whether showing your medical records is enough.

What happens when you renew your license

If your license already has a DD notation, it will carry forward to your new license when you renew — you do not have to request it again. However, some states do require you to provide updated medical documentation at renewal time to confirm the disability is still present.

If you did not have DD on your old license but want it on your new one, you can request it during the renewal process. Bring your medical documentation with you, or submit it ahead of time if your state allows online renewal.

Removing the DD notation

You can request that the DD notation be removed from your license at any time. You do not need a reason, and you do not need new documentation. straightforward contact your DMV and ask to have it removed, or request its removal during your next renewal.

Some people add DD when they first get their license and remove it later, or vice versa. The choice is always yours, and you can change your mind as many times as you need to.

How law enforcement may respond to DD

When an officer sees DD on your license during a traffic stop, they may take extra time to explain what they need from you or ask if you need information. Some departments have training on how to interact with people who have developmental disabilities, and the notation can prompt them to use that training.

In an emergency or accident, the DD notation alerts paramedics and hospital staff that you may need communication support or may respond differently to stress. This can lead to better care and fewer misunderstandings in a crisis.

That said, the notation does not may provide any particular response. It is a tool that may help, but it is not a substitute for telling an officer directly if you need help or have a condition they should know about.

Frequently Asked Questions

Does DD on my license mean I cannot drive?

No. The DD notation is informational only and does not restrict your driving privileges. You took the same written and road tests as any other driver, and you have the same license class and driving rights.

Will having DD on my license affect my insurance rates?

No. Insurance companies do not see the DD notation on your license, and it does not factor into your rates or coverage. Your driving record and claims history are what affect your insurance.

Can I request DD if I have a mental health condition instead of a developmental disability?

DD is specifically for developmental disabilities — conditions that began in childhood and affect overall functioning. Mental health conditions like depression or anxiety are not developmental disabilities. Talk to your DMV about what notations, if any, might explore to your situation.

What if I lost my documentation but still want DD on my license?

Can someone else request DD on my license for me?

No. You must request it yourself or authorize someone in writing to do so on your behalf. If you have a guardian, they may be able to request it, but the DMV will explain their process when you contact them.
