A DUI arrest in San Francisco starts two separate cases at once. A San Francisco DUI lawyer defends the criminal case in San Francisco Superior Court. The same lawyer also handles the DMV administrative case that decides your license. The DMV track carries a short deadline to request a hearing. Missing this deadline may cost your driving privileges. Our firm defends DUI, DUI-drug, and underage DUI charges throughout San Francisco, CA. What you face depends on the facts of your case.
What Counts as a DUI in San Francisco?
California law makes it a crime to drive under the influence of alcohol, drugs, or both. California defines the DUI offense by statute. Prosecutors do not always need a chemical test result. A case may proceed on impairment evidence alone, such as driving pattern and field sobriety test performance.
The blood alcohol limits that apply in San Francisco vary by driver. Most drivers face a 0.08% limit. Commercial drivers face 0.04%. Drivers under 21 face a 0.01% limit. Anyone on DUI probation also faces this lower limit. A small amount of alcohol can trigger underage DUI charges. Drug cases have no per-se limit. DUI-drug charges usually turn on officer testimony and blood test results. California uses the term DUI, not DWI, OWI, or OVI.
DUI Checkpoints and Chemical Testing in San Francisco
Clients often ask about DUI checkpoints San Francisco police run on weekend nights. Departments must announce these checkpoints in advance and hold them at fixed locations. Officers must also follow a neutral stopping formula, such as every third car. When the stopping sequence departs from that formula, the departure can support a motion to suppress.
Chemical testing follows its own rules. Under California's implied consent law, a driver lawfully arrested for DUI is deemed to have consented to a breath or blood test. Refusing may bring a separate license penalty on top of the criminal case.
The roadside breath test before arrest is usually a preliminary screening device. Implied consent covers the evidentiary test given after arrest. An attorney can provide guidance on what occurred during your stop.
Penalties and License Consequences After a San Francisco DUI Arrest
Every case runs on two tracks. The criminal case moves through San Francisco Superior Court at the Hall of Justice. The DMV runs a separate action against your license. You have only a short window after arrest to request that hearing. Requesting it on time is the most time-sensitive step in the case.
A first conviction under the DUI statute may bring county jail exposure. Fines plus substantial court assessments may apply. A license suspension and DUI school are typical. Courts often address the jail exposure through probation. Prior convictions within the past ten years raise that exposure. A second or third offense may mean mandatory jail. A longer suspension may apply. DUI school may last 18 to 30 months. An ignition interlock device may also be required.
What applies in your case depends on your BAC level, your prior record, and the facts of the arrest.

Frequently Asked Questions
Are DUI checkpoints in San Francisco legal, and can I turn around to avoid one?
Yes, checkpoints are legal when police announce them and follow a neutral stopping formula. A driver may generally turn away before entering. But officers may still stop you for an independent traffic violation.
What happens to my license after a DUI arrest in San Francisco?
The DMV moves to suspend your license unless you request an administrative hearing within the short window after arrest. That case runs separately from the criminal charge.
Can I be charged if my BAC was under 0.08%?
Yes, prosecutors may file charges on impairment evidence alone. Lower limits also apply to commercial drivers, drivers under 21, and anyone on DUI probation.
What happens if I refuse a breath or blood test?
Refusing the post-arrest test after a lawful DUI arrest may add a license penalty on top of the criminal case. Consulting with an attorney about your specific stop is advisable.
