DUI Accidents at California Intersections: What’s Being Done and How to Defend Against Charges
Intersections are among the most dangerous places on California roadways, and when an impaired driver enters the mix, the results are frequently catastrophic. Multiple lines of travel, left-turn conflicts, pedestrians, and split-second signal timing already make intersections high-risk locations. Add alcohol or drug impairment to that equation, and reaction time, judgment, and hazard perception all suffer at exactly the moment drivers need them most. For anyone facing a DUI charge stemming from an intersection collision in Orange County or elsewhere in California, understanding both the safety landscape and the available legal defenses is essential.
The Scope of the Problem
California has consistently ranked among the states with the highest number of alcohol-related crashes nationwide. State data shows more than 1,300 people die each year in impaired-driving collisions statewide, accounting for roughly a third of all traffic fatalities in the state, and DUI arrests have topped 120,000 annually in recent years. Intersections play an outsized role in this picture because they concentrate the conflict points where vehicles cross, merge, and turn across each other’s paths. Impaired drivers who misjudge a signal change, roll through a stop sign, or fail to yield at a green arrow create exactly the kind of T-bone and left-turn collisions that tend to produce serious injuries.
Field Sobriety Tests in California: How They Work, Why Drivers Comply, and Your Legal Rights
If you have ever been pulled over on suspicion of DUI in Orange County, you likely encountered a series of on-the-spot physical and cognitive exercises before an arrest was made. These are known as Field Sobriety Tests (FSTs), and they play a central role in most California DUI investigations. Understanding how these tests are administered, why so many drivers cooperate even when they don’t have to, and what legal defenses can arise from flawed testing is critical if you’re facing a DUI charge.
What Are Field Sobriety Tests?
Field sobriety tests are a set of physical and mental exercises officers use to estimate whether a driver is impaired by alcohol or drugs. The National Highway Traffic Safety Administration (NHTSA) has validated three “standardized” tests that most California law enforcement agencies use:
A DUI Can Cost You Your California Nursing License — How can you Protect It?
A DUI arrest is stressful enough on its own, but for registered nurses, LVNs, and nursing students in California, it carries a second layer of risk most people never have to consider: losing the professional license that supports their entire career. The Board of Registered Nursing (BRN) treats a DUI conviction as unprofessional conduct, separate from whatever happens in criminal court, and has full authority to investigate, discipline, suspend, or revoke a nursing license as a result.
If you’re a nurse facing DUI charges in Orange County, understanding how criminal court and professional licensing intersect is the first step toward protecting both your freedom and your livelihood. At the Law Offices of William M. Weinberg, we represent nurses and other licensed professionals throughout California, building defense strategies that account for both sides of the problem from day one.

California’s New Bail Decision: What In re Kowalczyk Means for Defendants, Families, and the Future of Bail in California California Supreme Court Issues Landmark Bail Decision
The California Supreme Court’s recent decision in In re Kowalczyk is one of the most significant developments in California criminal law and pretrial release procedures in years. Building upon the Court’s earlier ruling in In re Humphrey, the new decision further limits the ability of courts to rely upon unaffordable money bail as a means of keeping defendants in custody while their cases are pending.
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.

First DUI Arrest in California? Here’s What Happens Next
If you were just arrested for DUI in California for the first time, you’re probably scared, confused, and wondering what comes next. That’s completely understandable. A DUI arrest does not automatically mean a conviction, and there are steps you can take right now to protect yourself.
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.
California DUI Law Update 2026: Recent Court Decisions Every Driver Should Know
A DUI arrest in California triggers two separate legal proceedings: the criminal court case and the Department of Motor Vehicles (DMV) administrative action. While most drivers focus on the criminal DUI charges and potential court penalties, recent California appellate decisions show that DMV hearings remain one of the most important battlegrounds in DUI defense.
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
Can I lose my children if I’m arrested for a DUI while they are in the car?
A DUI arrest involving children in the car can spill into family court very quickly, even if the criminal case is still pending. In many jurisdictions, police are required to notify child protective authorities when a young child is allegedly placed at risk. A four-year-old passenger especially increases the chance of a referral.
That does not automatically mean someone loses custody. But it can trigger investigations, emergency hearings, temporary restrictions, or court-ordered supervision.
Common family court consequences may include:
ATTACKING BREATH TEST RESULTS IN A CALIFORNIA DUI CASE
A DUI arrest in California does not automatically mean a conviction. One of the most powerful — and frequently successful — defense strategies is challenging the validity of the breath test. Breath testing technology, while widely accepted, is riddled with potential errors that an experienced DUI defense attorney can exploit. Understanding these vulnerabilities is critical for anyone facing charges under California Vehicle Code Sections 23152 or 23153.
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.
