For anyone arrested in California, including those facing DUI charges, drug crimes, theft offenses, domestic violence allegations, or other criminal charges, the Kowalczyk decision may have a substantial impact on whether they remain in jail or are released while awaiting trial.

Understanding Bail in California

Quick Answer: What Happens After a First DUI Arrest in California?

After a first-time DUI arrest in California, two separate processes begin at the same time: a criminal court case and a DMV administrative hearing. You have only 10 days from the date of your arrest to request a DMV hearing, or your driver’s license will be automatically suspended. On the criminal side, you will face charges under Vehicle Code 23152, with possible penalties including fines, probation, DUI school, and jail time. An experienced DUI lawyer can challenge the evidence and potentially get your charges reduced or dismissed.

Several significant cases decided in 2025 and 2026 have clarified the rights of drivers facing license suspensions and have highlighted important procedural issues that can determine whether a suspension stands or falls.

The DMV Hearing Still Matters

That does not automatically mean someone loses custody. But it can trigger investigations, emergency hearings, temporary restrictions, or court-ordered supervision.

How Breath Tests Work — and Where They Fail

California law enforcement primarily uses two devices: the Draeger Alcotest and the Intoxilyzer 8000. Both rely on infrared spectroscopy to estimate blood alcohol concentration (BAC) from a breath sample. The device measures ethanol molecules in deep lung air (alveolar air) and extrapolates a BAC using a partition ratio — the assumed ratio of alcohol in blood to alcohol in breath. California courts use a standardized partition ratio of 2,100:1, meaning 2,100 milliliters of breath contains the same alcohol as 1 milliliter of blood. The problem? This ratio varies significantly from person to person and even within the same individual depending on body temperature, lung capacity, and other physiological factors. A person with a higher-than-average partition ratio may produce a falsely elevated BAC reading.

Driving under the influence cases in California tend to follow recognizable patterns. If you understand the most common DUI scenarios, you can spot where the prosecution’s case is weak—and where a defense attorney can create leverage. Below is a practical, real-world breakdown of typical DUI situations and the defenses that actually work.

How Often Do People Drive Impaired Before Being Caught?

There’s no way to know precisely how many times every individual driver has operated a vehicle while intoxicated before an arrest. Law enforcement and researchers don’t have access to hidden behavior that goes unreported or undetected. However, multiple studies and expert estimates provide a broad picture:

A DUI arrest is always serious. When a child is in the vehicle, the consequences become far more severe—and far more personal. In Orange County, prosecutors aggressively pursue these cases, and they often involve mandatory jail time, child endangerment allegations, and Child Protective Services (CPS) investigations.

If you were arrested for DUI with a child passenger in Anaheim, Santa Ana, Irvine, Huntington Beach, Garden Grove, Fullerton, or anywhere else in Orange County, it is critical to understand what you are facing and how early legal intervention can protect both your freedom and your family.
