DUI defense in Modesto and Stanislaus County
A DUI arrest sets two cases in motion: a criminal case in Stanislaus County Superior Court, and a separate action against your license at the DMV. Each runs on its own track and its own timeline.
A former prosecutor's read on a DUI case
Matthew Begoun was a Deputy District Attorney in Stanislaus County before opening this practice. DUIs are a substantial part of any local DA office's caseload. From the prosecution side, he saw which cases get filed at the standard DUI count, which ones get reduced to wet-reckless at filing, which ones the office writes up as felonies, and which ones get rejected for proof problems before they ever reach a courtroom.
Knowing where a case sits in that filing logic — before negotiations begin — is part of how DUI cases get resolved efficiently.
The 10-day rule
You have 10 calendar days from the date of your arrest to request an Administrative Per Se (APS) hearing with the DMV. Miss the deadline and the suspension takes effect automatically — usually 30 days after arrest. Request the hearing in time and the suspension is stayed until the hearing is decided.
This is the single most time-sensitive thing on a DUI case, and it has nothing to do with whether you're guilty.
What we handle
- First-time DUI — Vehicle Code 23152(a) and (b). Most are misdemeanors. Penalties typically include fines, license suspension, DUI school, and probation.
- Second and third DUI — Priors stack. A second within 10 years carries a longer suspension and minimum jail. A third within 10 years carries up to one year in county jail and a three-year suspension.
- Felony DUI — A fourth DUI within 10 years, or any DUI causing injury (VC 23153), or any DUI with a prior felony DUI conviction. State prison is on the table.
- Refusal cases — Refusing the post-arrest chemical test triggers a longer DMV suspension regardless of the criminal outcome. The "refusal" finding has its own elements; not every refusal is actually a refusal under the statute.
- Underage and commercial DUIs — Different BAC thresholds, different consequences for your license and your CDL.
- DUI with drugs — Cannabis, prescription medications, and controlled substances. There's no per-se threshold for most drugs in California, which makes these cases very different from alcohol cases.
What I look at first
Before talking about pleas, I read the case the way the DA reads it.
- The stop. Was there reasonable suspicion to pull you over, or was it a hunch? A bad stop suppresses everything that follows.
- The investigation. Field sobriety tests are scored, and the officer either followed the NHTSA standards or didn't. Body-cam usually shows whether they did.
- The breath test. The Title 17 regulations for breath testing — the 15-minute observation period, two breath samples, calibration logs — are real and routinely violated.
- The blood test. Chain of custody, drawing protocol, and the right to an independent re-test.
- Rising-alcohol issues. Alcohol absorbed during driving but not yet in your blood is a real defense, especially when the test was hours after the stop.
DMV vs. court
— DMV (APS) — Criminal court
What's at stake — Your license — Jail, fine, probation, license restriction
Standard of proof — Preponderance of the evidence — Beyond a reasonable doubt
Deadline to act — 10 calendar days from arrest — First court date is on the citation
Where it happens — Driver Safety Office (Stockton) — usually telephonic — Stanislaus County Superior Court, 801 10th St, Modesto
You can win a DMV hearing and lose the criminal case, or vice versa. Both matter.
Restricted licenses and IIDs
Most DUI suspensions in California can be converted to a restricted license — sometimes immediately with an Ignition Interlock Device (IID), sometimes after a short hard suspension. The right path depends on prior history, whether it's a refusal, and whether there was an injury.
What this might cost you, beyond the case
For some clients, the criminal sentence isn't the worst consequence.
- Employment. Drivers, nurses, teachers, contractors, military, and security-cleared workers all face professional license or background-check issues that go well past the criminal court.
- Immigration. A DUI is not always a deportable offense, but it can trigger problems with naturalization, conditional status, and DACA. Don't plead to anything without an immigration analysis.
- Insurance. Most carriers raise rates for years after a DUI. An SR-22 filing is required for license reinstatement.
- Housing and custody. DUIs come up in family-court custody disputes more often than people expect.
What to do today
- Call before you talk to anyone else about the case — including officers asking follow-up questions.
- Note the date of arrest. Day 1 is the day after arrest. Day 10 is the deadline to request the DMV hearing.
- Don't post about it.
