What is DUI Defense in California?
Driving Under the Influence in California is prosecuted under Vehicle Code §23152, which makes it a misdemeanor to drive with a blood-alcohol concentration (BAC) of 0.08% or higher (commercial drivers 0.04%, drivers under 21 0.01%) or to drive while impaired by alcohol or drugs. A DUI conviction triggers both a criminal case and a separate DMV Administrative Per Se (APS) action against your license — the DMV hearing must be requested within 10 days of arrest.
Morris Law PC, A Criminal Defense Firm, represents clients facing these charges across Alameda County and the greater Bay Area. With offices in Oakland and Berkeley, our team brings courtroom-tested defense to every stage of the case — from arrest and arraignment through trial, sentencing, and post-conviction relief.
Charges & Penalties Under California Law
- First-Offense DUI (VC 23152). Up to 6 months county jail, $390–$1,000 fine plus penalty assessments, 6-month license suspension, 3-month or 9-month DUI school, 3–5 years summary probation.
- Second-Offense DUI (within 10 years). 96 hours to 1 year county jail, $390–$1,000 fine, 2-year license suspension, 18-month or 30-month DUI school, mandatory IID.
- Third-Offense DUI. 120 days to 1 year county jail, 3-year license revocation, 30-month DUI school, IID required.
- Felony DUI (VC 23153 — DUI with injury, or 4th DUI in 10 years). 16 months, 2, or 3 years state prison (more with great bodily injury enhancements), 4-year license revocation, designation as a Habitual Traffic Offender.
- Vehicular Manslaughter While Intoxicated (PC 191.5). Up to 10 years state prison for gross vehicular manslaughter; 15 years to life for second offense or with prior DUI history (Watson murder, PC 187).
- Underage DUI (VC 23136 / 23140). Zero-tolerance: any measurable BAC for a driver under 21 results in a 1-year license suspension; 0.05%+ adds criminal penalties.
Defenses Our California Lawyers Use
- Challenge the traffic stop. Under People v. Wells (2006) and the Fourth Amendment, officers need reasonable suspicion to stop you. Weaving within your own lane, briefly touching a line, or a tip from an anonymous caller may not be enough.
- Attack the field sobriety tests (FSTs). Only three FSTs are NHTSA-standardized (HGN, walk-and-turn, one-leg stand). Medical conditions, footwear, road slope, fatigue, and officer instructions all affect results. Non-standardized tests (counting, alphabet) are not scientifically validated.
- Challenge the breath test. Title 17 of the California Code of Regulations requires a 15-minute observation period, two breath samples within 0.02 of each other, and properly maintained equipment. Mouth alcohol (burping, GERD, recent drink) can produce false highs.
- Rising BAC defense. Alcohol absorbs over 30–90 minutes. If you stopped drinking shortly before driving, your BAC may have been below 0.08% while driving but climbed above by the time of testing.
- Title 17 blood draw violations. Blood samples must be drawn by a qualified phlebotomist using non-alcohol-based antiseptic, with proper preservatives, refrigeration, and unbroken chain of custody.
- Medical and dietary defenses. Diabetes (ketones), keto diets, GERD, and certain medications can produce false-positive readings on breath devices.
- DMV-side defense (APS hearing). Even if criminal charges proceed, we can challenge the DMV suspension separately to keep you driving while the case is pending.

Frequently Asked Questions
What is the legal BAC limit in California?
0.08% for drivers 21 and over, 0.04% for commercial drivers, and 0.01% for anyone under 21 (zero-tolerance). Commercial drivers can also be charged at 0.04% in any vehicle. You can be convicted below the limit under Vehicle Code §23152(a) if the prosecution proves impairment.
Do I have to take a breath or blood test in California?
Pre-arrest, the PAS (preliminary alcohol screening) handheld test is voluntary for drivers 21+ unless you are on DUI probation. Post-arrest, California’s implied-consent law (VC §23612) requires a breath or blood test — refusal triggers a 1-year license suspension on a first offense and adds jail time if convicted.
How long do I have to request a DMV hearing after a DUI arrest?
You have 10 calendar days from the arrest date to request the Administrative Per Se (APS) hearing. If you miss this deadline, your license will be automatically suspended 30 days after arrest. We can request the hearing the same day you call us.
Will I lose my license if I am convicted of a first DUI in California?
Yes — a first-offense conviction triggers a 6-month license suspension by the court, but you can typically apply for a restricted license after 30 days if you enroll in DUI school and file an SR-22. Drivers under 21 face a full 1-year suspension.
Can a California DUI be reduced to a wet reckless?
Yes. A ‘wet reckless’ (VC §23103.5) is the most common DUI reduction — it carries no mandatory license suspension from the court, lower fines, and counts as a prior only if you are arrested for another DUI within 10 years. We negotiate wet recklesses where the BAC, driving pattern, and case facts support it.
