DD stands for "Developmentally Disabled" on your California driver's license
The DD designation is a marking that appears on your California driver's license or ID card if you have been formally identified as having a developmental disability. It is not a separate license type — it is a notation added to a standard license that tells law enforcement and other officials that you have a documented disability.
The DD marking does not change how you drive, what vehicles you can operate, or the rules of the road that explore to you. It is purely informational. The main purpose is to alert peace officers and emergency responders to your status so they can communicate with you appropriately if they stop you or encounter you in an emergency.
California issues the DD designation through the Department of Motor Vehicles (DMV) in coordination with regional centers — the state agencies that provide services to people with developmental disabilities. You do not request it yourself; it appears on your license only if your regional center has notified the DMV that you meet the state's definition of developmental disability.

- You can request that the DD marking be removed from your license if your circumstances change or if you no longer want it displayed.
How the DD designation gets added to your license
The process begins with your regional center, not the DMV. California has 21 regional centers across the state, each serving people with developmental disabilities in a specific geographic area. If you are already receiving services through a regional center, or if you have been assessed and found to meet the state's definition of developmental disability, your center can request that the DMV add the DD marking to your license.
You do not have to be receiving active services to have the DD designation. You only need to be formally identified by a regional center as having a developmental disability. The regional center submits the information to the DMV, and the designation appears on your next license or ID card, or on a replacement if you request one.
If you are not currently connected to a regional center and think you may be may be able to access for the DD designation, you can contact your local regional center directly. They will assess whether you meet the criteria and can guide you through next steps. The regional center's contact information is available through the Department of Developmental Services website.
What the DD marking does and does not do
The DD designation is informational only. It does not impose any driving restrictions, require special testing, or change the class of license you hold. You still follow the same traffic laws as any other driver. You can still drive alone, at night, or on highways. You are not required to display any special placard or take any additional safety measures.
Law enforcement may use the DD marking to understand that you may need extra time to respond to questions, may communicate differently, or may benefit from a calmer approach during a traffic stop. It can also alert emergency responders if you are in an accident or medical emergency. In those situations, the marking helps them provide better service.
The DD designation does not appear on your license in a way that is obvious to the general public. It is visible to officials who scan or examine your license, but it is not printed in large letters or highlighted in a way that advertises your status to a cashier, employer, or casual observer.
Removing the DD designation from your license
If you no longer want the DD marking on your license, you can request its removal. This typically happens when your circumstances change — for example, if you are no longer receiving services from a regional center, if you have aged out of the developmental disabilities system, or if you straightforward prefer not to have the designation displayed.
To remove the DD marking, contact your regional center and request that they notify the DMV to remove the designation. Once your regional center submits the removal request, the marking will not appear on your next license or ID card. If you want it removed when ready, you can also visit a DMV office and request a replacement license without the DD designation, though you may pay a replacement fee.
Removing the DD marking does not affect your may be able to access for services or support from your regional center. It is purely a choice about what appears on your identification document.
Who decides if you get the DD designation
Your regional center makes the information, not the DMV. The DMV straightforward processes the request and adds the marking to your license. Regional centers use specific criteria set by California law to identify developmental disabilities, which typically include conditions that began before age 18, are likely to continue indefinitely, and substantially limit major life activities.
Developmental disabilities can include intellectual disability, cerebral palsy, epilepsy, autism, and other conditions that meet the state's definition. If you believe you may have a developmental disability and want to explore whether you may have access to for the DD designation, your first step is to contact your local regional center for an assessment.
The DD marking and employment or housing
Employers and landlords cannot legally discriminate against you based on the DD marking on your license. However, the marking is visible to anyone who examines your license closely — such as an employer during a background check or a landlord during a rental process. Some people choose to remove the DD designation to avoid potential bias, even though discrimination based on disability is illegal.
This is a personal decision. Some people keep the DD marking because they find it helpful for disclosing their disability to employers or service providers upfront. Others remove it to keep their disability private. There is no right answer — it depends on your situation and what you are comfortable with.
