Overview
If you're facing a third DUI, you already know the drill, and you also know the stakes have climbed. California treats a third DUI within the 10-year washout period seriously, with mandatory jail, a long license revocation, and the label of a habitual traffic offender. It's a heavy situation. But heavy is not hopeless, and a third-offense charge still has to be proven. There is meaningful defense work to do here, and doing it early gives you the best shot at a better outcome.
A third DUI within 10 years is generally charged as a misdemeanor under Vehicle Code 23152(a) and 23152(b), though the penalties are far tougher than a first or second. Exposure typically includes a mandatory minimum jail term measured in months rather than days, an extended DUI education program that commonly runs 30 months, substantial fines and fees, a multi-year revocation of your driving privilege, and designation as a habitual traffic offender. Informal probation of 3 to 5 years is standard, with strict terms. Depending on the facts, and particularly if there was an injury, the prosecutor may have the option to charge a DUI as a felony, which raises everything further. Our felony DUI page covers that scenario.
The washout period is central again. California counts prior DUIs within 10 years of the current offense when deciding how to enhance penalties. Two qualifying priors inside that window make the new case a third. If one of the priors is older than 10 years, or if a prior can be challenged, your exposure can change substantially. This is one of the first things worth examining. Our second DUI page explains how the washout math works on repeat cases.
And the case is still two cases. There's the criminal matter in San Diego County Superior Court and the DMV administrative action over your license, which on a third offense means a lengthy revocation rather than a short suspension. The 10-day rule still governs the DMV side: you generally have only 10 days from arrest to request a hearing. Given how long a third-offense revocation lasts, protecting that deadline is critical. The DMV hearings process is its own fight.
Joe's Approach
A third DUI is not a case to hand off to whoever is available. It needs an attorney who will actually work it, and that's how Joe Crudo practices. When you hire Crudo Law, Joe is the lawyer on your file from the first call through the last court date. Direct attorney access, thorough investigation, and a defense built around the specific facts of your case.
Joe understands what a third offense means for a person's life. The mandatory jail, the long revocation, the habitual offender label, and the fear that a job or a family situation can't survive it. He takes that seriously, and he takes the defense just as seriously. He doesn't treat a third DUI as a foregone conclusion, because the state still has to prove the current charge and still has to rely on priors that may not be as solid as they look.
His method is methodical. Go through the current arrest for every weakness in the stop, the field testing, and the chemical evidence. Then scrutinize each prior conviction, because on a third offense the priors are doing a huge amount of the sentencing work, and if one can be knocked out or shown to be outside the washout window, the whole calculus shifts. Joe would rather find the real leverage than push you toward the quickest plea. You can learn more about his philosophy on the about page.
Defense Strategies
Defending a third DUI means fighting on two fronts at once: the current case and the priors that are driving the enhanced penalties.
Challenge the stop. The traffic stop needs a lawful basis. If the officer had no reasonable suspicion or other valid reason, the evidence that came after may be suppressed, which can weaken or unravel the case no matter how many priors you have.
Attack the chemical evidence. Breath instruments must be calibrated and maintained, and the testing procedure, including the observation period, has to be done right. Blood samples must be properly drawn, stored, and analyzed, and a portion can often be independently retested. Mouth alcohol, medical issues, and timing can all skew results. Our BAC defense page covers these challenges in detail.
Use the rising blood alcohol timeline. Alcohol absorbs over time, so your BAC while driving may have been below the level recorded later at the station. In a close case, that timing can matter.
Question field sobriety testing. These tests are affected by nerves, fatigue, injuries, footwear, and roadside conditions, and how they were given and scored is open to challenge.
Attack the priors. This is where a third-offense defense often lives or dies. A prior only enhances your current sentence if it's valid and within the 10-year washout period. If a prior conviction was constitutionally defective, or if it falls outside the window, its use against you can be contested. Removing even one prior can change a third-offense case into something far less severe.
The purpose of all of this is leverage, whether the goal is a dismissal, a reduction, or a negotiated resolution that keeps the consequences as contained as the facts allow. Nobody can promise an outcome, but a fully investigated case is worth far more than an unexamined one.
Potential Outcomes
Every third-DUI case turns on its own facts, so there's no guaranteed result. Here's the honest range of where these cases can go.
Dismissal. If the stop was unlawful or the chemical evidence is fatally flawed, the charges may be dismissed. That depends on the specific facts and the law, and it isn't guaranteed.
Reduction or reclassification. Depending on the strength of the current case and the status of the priors, there may be room to reduce the charge or to challenge the priors so the case is scored as something less than a third. Getting a prior thrown out or washed out can meaningfully lower the mandatory minimums in play.
Negotiated resolution within the mandatory framework. A third DUI carries mandatory minimum jail, but how that time is served can sometimes be negotiated, and in some cases there are custody alternatives worth pursuing depending on the county and the facts. The probation terms and program requirements are also areas where an experienced negotiator can make a difference.
On the DMV side, a third offense generally means a multi-year revocation of your driving privilege rather than a short suspension, and reinstatement usually requires an ignition interlock device along with other conditions. The path back to legal driving is longer, which is all the more reason to fight the DMV case and protect that 10-day deadline. See our license suspension page and ignition interlock page for how those pieces work.
