California DUI Laws 2026 — Complete Guide

Quick Summary: California DUI under Vehicle Code §23152 carries fines up to $18,000, license suspension, DUI school, and possible jail. You have only 10 days after arrest to request a DMV APS hearing or your license is automatically suspended.

California DUI Law Overview

California Vehicle Code §23152 makes it unlawful to drive under the influence of alcohol and/or drugs. It's one of California's most frequently charged offenses, with San Diego County prosecuting thousands of DUI cases annually.

Unlike some states, California DUI law operates on two tracks simultaneously: the criminal court case (misdemeanor or felony) and the DMV Administrative Per Se (APS) hearing, which can suspend your license independent of the criminal case.

Blood Alcohol Concentration (BAC) Limits

Driver Category	BAC Limit	Legal Basis
Standard adult (21+)	0.08%	Vehicle Code §23152(b)
Commercial drivers	0.04%	Vehicle Code §23152(d)
Drivers under 21	0.01%	Vehicle Code §23136
DUI probation	0.01%	Vehicle Code §23154
Extreme DUI	0.15%+	Vehicle Code §23578 (enhanced penalties)

California also has an "impaired to the slightest degree" standard under §23152(a) — you can be charged with DUI even if your BAC is under 0.08% if the officer observes impairment.

The Critical 10-Day Rule

IMPORTANT: After a DUI arrest in California, you have 10 calendar days to contact the DMV to request an Administrative Per Se (APS) hearing. Missing this deadline results in automatic license suspension — even if you're later found not guilty in criminal court.

When you request the APS hearing, your temporary license remains valid until the hearing decision. A DUI defense attorney can request and handle the APS hearing on your behalf.

Felony DUI Under Vehicle Code §23153

Common DUI Defenses in San Diego

An experienced San Diego DUI defense attorney can challenge:

Unlawful traffic stop — No reasonable suspicion to stop your vehicle
Field sobriety test errors — NHTSA standards not followed
Breathalyzer calibration — Device maintenance records, operator certification
Rising BAC defense — BAC was rising between driving and testing
Medical conditions — GERD, diabetes, or other conditions causing false readings
Blood sample chain of custody — Improper storage or handling
Miranda violations — Statements obtained without proper warnings

Wet Reckless (Vehicle Code §23103.5)

A "wet reckless" is a negotiated reduction from DUI to reckless driving with alcohol noted. Advantages include: lower fines, shorter DUI school (possibly 12 hours vs. 3 months), no mandatory IID. Disadvantage: still counts as prior DUI for 10 years if you're arrested again.

DUI and San Diego County Courts

San Diego has multiple Superior Court divisions handling DUI cases:

Central Division — Downtown San Diego
South County Division — Chula Vista
East County Division — El Cajon
North County Division — Vista

Each division has different prosecutors and judges with varying tendencies on DUI plea offers. A local San Diego DUI defense attorney with experience in the specific courthouse handling your case has a significant advantage.
