I am Joel Brand, and I defend DUI cases across California. If you were just arrested and someone mentioned the word "diversion," you are probably wondering what it means, whether you qualify, and whether it is worth pursuing. This post walks through the two programs people ask about most, why only one of them is actually available in a California DUI, and the practical questions you need answered before your arraignment.
What Diversion Actually Means in a DUI Case
Diversion is a court process that allows a defendant to complete certain requirements, such as treatment, classes, or supervision, and then have the charges dismissed without a conviction on their record. It is not a guaranteed right, and it is not available to everyone. But for those who do qualify, it can mean the difference between a clean record and a criminal conviction that follows them for years.
The Two Main Diversion Programs in California DUI Cases
The two programs that come up most often in California DUI cases are military diversion under Penal Code 1001.80 and mental health diversion under Penal Code 1001.36. They share a similar goal, keeping a conviction off your record, but they serve very different populations, and only one of them is available in a DUI case at all. Confusing the two is the most common mistake I see people make when they research this topic on their own.
Military Diversion: Who It Is For
Military diversion under PC 1001.80 is available to current or former members of the United States military who are charged with a misdemeanor and who are suffering from service-related trauma, PTSD, substance abuse, or mental health issues linked to their service. If the court grants military diversion, proceedings are suspended while you complete a treatment program. When you complete it successfully, the charges are dismissed and the arrest may be sealed. This program exists because the legislature recognized that some veterans end up in the criminal justice system as a direct result of what they experienced in uniform. If you served, this is worth exploring immediately, before your first court date.
Mental Health Diversion: Why It Does Not Reach a DUI
PC 1001.36 allows diversion for defendants who have a diagnosed mental health disorder that contributed to the charged offense. It is broader than military diversion in who it covers, and it is the program people most often hope applies to them. In a DUI it does not. Vehicle Code 23640 bars it outright, and the Courts of Appeal settled the question in Tellez v. Superior Court and Moore v. Superior Court, both decided in 2020. In 2025 the Second District went further in People v. Garcia, holding that if a DUI count is in the case, the non-DUI counts from the same incident are barred too. This is not a question that turns on your judge, your county, or the strength of your diagnosis. If you were not in the military, mental health diversion is not the path, and you should be skeptical of anyone who tells you otherwise.
How These Programs Compare Side by Side
Military diversion requires documented military service and a service-related condition. Mental health diversion requires a qualifying DSM-5 diagnosis and a connection between that diagnosis and the conduct. Military diversion is explicitly written to cover misdemeanor DUI, in the words of the statute, notwithstanding Vehicle Code 23640. Mental health diversion has no such language, which is exactly why the courts have held it unavailable here. Military diversion, if completed, results in dismissal of the charges and gives you a path toward having the arrest sealed. Neither program is a plea of guilty, and neither results in the penalties described under California's DUI penalties guide.
What the Prosecution and Court Look At
Judges and prosecutors do not simply hand out diversion. They want to see that you have a genuine, documented condition, that you are engaged in treatment or willing to engage, and that granting diversion serves the interests of public safety. The documentation you gather before your arraignment matters a great deal. Medical records, a letter from a treating provider, evidence of prior treatment, and character letters can all support a diversion request. Walking into court with nothing but a verbal request rarely works.
The Timing Problem Most People Miss
Here is where a lot of people make a costly mistake. They wait until after they have entered a plea or negotiated a deal before asking about diversion. By that point, the window may have already closed. Diversion is typically raised before or at the arraignment, or very shortly after. If you think you might qualify, you need to flag it to your attorney before that first appearance. Waiting costs you leverage and, in some counties, costs you the opportunity entirely. This is one reason the choice between a public defender and a private DUI attorney can matter in terms of how much time and attention is dedicated to evaluating these options before your first court date.
What Happens After You Complete Diversion
If the court grants diversion and you complete the program successfully, the charges are dismissed. You can then pursue sealing the arrest record under PC 851.91. A sealed and dismissed case is treated very differently than a conviction for most purposes. It generally does not appear on background checks, it does not trigger the license consequences of a conviction, and it does not count as a prior DUI offense if you are charged again in the future. That last point alone makes diversion, when available, one of the most valuable outcomes in a DUI case.
What Diversion Does Not Fix
Diversion resolves the criminal court case. It does not automatically resolve the DMV side of things. California creates two separate legal proceedings when you are arrested for DUI: the criminal case and the administrative license action. Even if you obtain diversion in court, the DMV can still suspend your license through its own process. Understanding how the DMV hearing works and how it runs separately from the criminal case is important so you do not assume a diversion grant has solved everything.
Diversion Is Not the Only Tool
If you do not qualify for either diversion program, that does not mean a conviction is inevitable. There are still defenses to explore, potential reductions to a wet reckless or dry reckless, and mitigation strategies that can affect how the case resolves. Diversion is one path, not the only one. The goal is to find the best possible outcome given the specific facts of your arrest and your personal background.
What to Do Right Now
If you served in the military, tell your attorney immediately and ask about diversion under 1001.80. Do not wait to see how the case develops. Gather any VA records, medical records, or treatment history you already have access to. If you did not serve but a mental health condition genuinely contributed to what happened, that evidence still matters. It moves from a diversion request to the negotiation and to sentencing mitigation, and it needs to be documented just as carefully. The sooner you start building the record, the better positioned you will be.
