After an arrest, almost everyone wants to know the same thing: how long is this going to take? I am Joel Brand, and I defend DUI cases across California. The honest answer is that it depends, but the ranges are predictable, and understanding the timeline helps you make better decisions. The most important thing to know up front is that a DUI runs on two separate clocks at the same time, and they do not move at the same speed.
Two clocks start the moment you are arrested
Your DUI sets off a criminal court case and a separate Department of Motor Vehicles action at the same time. I explain why this matters in detail in your DUI creates two separate cases, but for timing purposes the key point is that the DMV side moves fast at the very beginning, while the court side tends to unfold over months. Missing the fast one can cost you your license before the slow one is anywhere near finished.
The DMV clock: 10 days, then a hearing
The DMV clock is the urgent one. You generally have only 10 days from the date of arrest to request a hearing to contest the automatic license suspension. If you miss that window, the suspension takes effect on its own. If you request the hearing in time, it postpones the suspension and buys time to challenge it. The hearing itself is usually scheduled weeks later, and a decision can take additional time. You can check your own deadline with the DMV hearing deadline calculator, and learn how the process works in understanding the DMV hearing. The very first steps are laid out in the first 10 days after a DUI.
The court clock starts with filing
On the criminal side, getting arrested is not the same as being charged. The prosecutor decides whether and when to file, and that can happen quickly or take weeks, especially if the case is waiting on blood test results from a crime lab, which routinely take several weeks to come back. There is also an outer limit. The state cannot wait forever to file, a subject I cover in the DUI statute of limitations. For a typical misdemeanor, expect the case to be filed within a few weeks to a couple of months of the arrest.
Arraignment: your first court date
Once charges are filed, the case begins with the arraignment, which is your first court appearance and where you enter a plea. For most misdemeanors this happens within a few weeks of filing, and in many cases your attorney can appear for you so you do not have to take the day off work. What actually happens that day is covered in what to expect at a DUI arraignment. Pleading not guilty at the arraignment is normal. It simply keeps your options open while your lawyer gets the evidence.
The pretrial phase is usually the longest
The heart of a DUI case is the pretrial phase, and it is where most of the time goes. Your attorney requests and reviews discovery, which means the police reports, the breath or blood records, the calibration and maintenance logs, and any body-camera and dash-camera footage. There are often several pretrial conferences where your lawyer and the prosecutor discuss the strengths and weaknesses of the case and explore a resolution. This back and forth is normal and it is where good outcomes are built. The full sequence is mapped out in the DUI court process step by step. For a first offense, this phase commonly runs a couple of months. A contested case with motions can run longer.
Motions and hearings add time, often for good reason
If there is a legal problem with the stop, the testing, or the way evidence was gathered, your lawyer may file motions, such as a motion to suppress evidence. Litigating a motion adds court dates and time to the calendar, but it can also be exactly what wins or shrinks the case. A short delay that produces a suppressed breath test or a dismissed charge is time well spent. In other words, fast is not always better.
Trial is rare, but it has its own timeline
Most DUI cases resolve without a trial, through a dismissal, a reduction, or a negotiated plea. When a case does go to trial, that adds months, because trials have to be scheduled around the court's calendar. You have a right to a speedy trial, which sets outer limits on how long the state can take, and that right can be used strategically. Sometimes asserting it pressures the prosecution, a tactic I describe in the strategic use of Penal Code 1382. Other times waiving it gives your defense more time to develop, which I cover in waiving your speedy trial right.
What makes a case take longer
Several things stretch the timeline. Waiting on blood results, a backed-up court calendar, complex facts, an accident or injury, prior offenses, and contested motions all add time. Continuances, which are postponements of a court date, are common and often used deliberately by the defense to gather evidence or improve the negotiating position. There is a real strategy to them, which I explain in leveraging continuances in DUI cases. The point is that a longer case is frequently a sign that your lawyer is working the case, not that something has gone wrong.
Realistic ranges
With all of that said, here is a rough guide. A straightforward first-offense misdemeanor often resolves within about two to five months from the arraignment. A case that is actively contested, with motions or trial preparation, can run six months to a year. A felony DUI, or one involving injury, generally takes longer because of the additional steps like a preliminary hearing. Your case may fall outside these ranges, and that is fine. The numbers are a frame, not a promise.
What you can do now
The single most time-sensitive thing is the 10-day DMV deadline, so handle that first. Beyond that, patience usually serves you well, because rushing to resolve a DUI is how people accept worse outcomes than they had to.
