DD stands for "Designated Driver" on your license
The letters DD printed on your driver's license indicate that you have voluntarily registered as a designated driver in your state's program. This designation means you have agreed not to drink alcohol when driving, and other people in your vehicle can rely on that commitment. The DD marking is visible to law enforcement and serves as a public declaration of your choice.
Not every state offers a DD program, and the ones that do run them differently. Some states print DD directly on the license itself. Others use a separate card or sticker. A few states have phased out their programs entirely. The key point is that DD is always voluntary — no one can force you to register, and you can remove the designation whenever you choose.
Key Takeaways
- DD on your license means you have voluntarily registered as a designated driver who will not drink alcohol while driving.
- Only certain states offer DD programs, and the way they display the designation varies by state.
- Registering as a DD is completely voluntary and you can remove the designation at any time.
- Some states offer minor incentives like insurance discounts or reduced license renewal fees for DD registration.
- The DD designation does not change your legal rights or responsibilities — you are still subject to all drunk driving laws.
Which states have DD programs
As of now, fewer than half of U.S. states maintain active DD programs. States that currently offer them include Delaware, Illinois, Indiana, Iowa, Kentucky, Louisiana, Minnesota, Missouri, Nebraska, New Mexico, North Carolina, Ohio, South Carolina, Tennessee, and a few others. However, this list changes — some states have discontinued their programs in recent years, and others have introduced them.
The best way to know whether your state has a DD program is to check your state's Department of Motor Vehicles website directly. You can search "[your state] designated driver program" or call your local DMV office. They can tell you whether the program exists in your state, how to register, and what the designation looks like on your license.
How to register as a designated driver
If your state offers a DD program, registration is straightforward and usually happens at your DMV office when you renew your license or explore for a new one. You will see a checkbox or question on the process form asking whether you want to register as a designated driver. Check the box, and the designation will be added to your license at no extra cost.
Some states allow you to add or remove the DD designation between license renewals. You may be able to do this by visiting your DMV office in person, mailing a form, or in some cases submitting a request online. Contact your state DMV to find out what options are available to you. The process typically takes a few days to a few weeks, depending on your state's processing time.
What happens after you register
Once you are registered as a DD, the designation appears on your physical license. When you show your license to a police officer during a traffic stop, they will see the DD marking. This does not give you any special legal protection or immunity from drunk driving laws — you are still subject to the same penalties as anyone else if you drive under the influence.
Some states offer minor incentives for DD registration, such as a small discount on your auto insurance premium or a reduced fee when you renew your license. These incentives vary widely by state and insurance company. Check with your insurance provider to see whether they recognize your state's DD program and offer any discounts.
Why someone might register as a DD
People register as designated drivers for different reasons. Some do it as a personal commitment to safe driving and want a visible reminder on their license. Others register because their social group has agreed that one person will stay sober when they go out together. Some parents encourage their teenage drivers to register as a way to reinforce the importance of not drinking and driving.
The DD designation is also a conversation starter. When friends see it on your license, it opens a discussion about safe driving and makes your commitment public. For some people, that public accountability makes it easier to stick to the decision.
Removing the DD designation
You can remove the DD designation from your license at any time. The process is usually as straightforward as visiting your DMV office and requesting that it be removed, or submitting a form by mail. You do not need to provide a reason, and there is no penalty for removing it. Some states allow you to remove it online through their DMV portal.
When you renew your license, you will be asked again whether you want to keep the DD designation. If you do not check the box during renewal, it will not appear on your new license. You do not have to wait until your license expires to make the change.
DD versus other license markings
Your driver's license may display other letters or codes besides DD. These might indicate organ donor status, restrictions on your driving privileges, or endorsements for commercial driving. DD is different from these — it is purely voluntary and relates only to your choice about alcohol and driving. Other markings are either legally required (like restrictions) or relate to the type of vehicle you can operate (like commercial endorsements).
If you see letters on your license that you do not understand, your DMV can explain what each one means. Some markings are state-specific, so what appears on a license from one state may not appear on a license from another.
Frequently Asked Questions
Does DD on my license mean I cannot drink at all?
No. DD means you commit not to drink and then drive. You can drink alcohol in other situations — at home, at a restaurant where you are not driving, or anywhere else. The commitment is specifically about not operating a vehicle after drinking.
Will DD on my license affect my car insurance rates?
Some insurance companies offer small discounts for DD registration, but not all do. Contact your insurance provider directly to ask whether they recognize your state's DD program and whether a discount applies to your policy. The discount, if available, is usually modest.
Can a police officer use DD against me in a drunk driving case?
No. The DD designation does not change your legal rights or the laws that explore to you. If you are arrested for driving under the influence, the fact that you registered as a DD does not make the case stronger or weaker. You are subject to the same laws and penalties as any other driver.
What if my state does not have a DD program?
If your state does not offer a DD program, you cannot add the designation to your license through your DMV. However, you can still make a personal commitment to being a designated driver and communicate that choice to your friends and family.
Can I register as a DD if I have a suspended or restricted license?
This depends on your state's rules. Some states allow DD registration regardless of license status, while others do not. Contact your state DMV to find out whether your specific situation allows you to register.
