DD stands for "Developmental Disability" on your California driver's license
The letters DD printed on your California driver's license indicate that you have disclosed a developmental disability to the Department of Motor Vehicles. This is a voluntary designation — you do not have to request it, and the DMV will not add it without your consent. The code appears in the same area where other designations like organ donor status or veteran status are marked.
The purpose of DD is to alert law enforcement and emergency responders that you may need different communication or information during a traffic stop or emergency. It is not a medical diagnosis, a restriction on your driving privileges, or a public record. The designation stays between you, the DMV, and anyone who checks your license during an official interaction.

Why someone might request DD on their license
People request DD for different reasons. Some have an intellectual disability, autism spectrum disorder, cerebral palsy, or another condition that affects how they communicate or process information. Others have a developmental disability that does not affect driving ability but might matter in a high-stress situation like a traffic stop.
The main reason to request it is to give law enforcement a heads-up before they approach your car. An officer who sees DD may speak more slowly, give clearer instructions, or call for a supervisor or social worker if the interaction becomes complicated. This can reduce misunderstandings and keep everyone safer.
Some people choose not to request DD even if they have a developmental disability. That choice is entirely personal. There is no benefit or penalty to having it or not having it — it is about whether you think the notification would help you in an emergency.

DD versus other DMV designations

Corrective lens restrictions show that you must wear glasses or contacts to drive. These are all separate from DD.
