DUI in California
DUI is prosecuted seriously under California law. The act poses serious risks for the impaired driver and anyone who crosses their path, not to mention the potential for significant property damage. In 2024 alone, 11,904 people across the nation died in preventable alcohol-related traffic accidents. The five counties in California with the most alcohol-related fatality cases are:
- Los Angeles County
- Riverside County
- San Bernardino County
- San Diego County
- Orange County
A DUI arrest will likely be overwhelming and chaotic. It’s helpful to hire a DUI lawyer who has experience navigating cases like yours. Your legal team can help you understand California DUI penalties based on the facts of your case and other important factors like your criminal history.
Can You Refuse a Breathalyzer in California? Understanding CA DUI Laws
If you’re arrested for DUI and asked to submit to a blood or breath test, you generally cannot refuse to take the test without legal repercussions. Every driver in California agrees to the state’s implied consent laws when they receive their driver’s license. This means that you must submit to chemical testing when prompted by law enforcement.
However, you can refuse a Preliminary Alcohol Screening (PAS) breathalyzer prior to your arrest as long as you’re not a minor. It also may be possible to request an alternative chemical test in lieu of a breathalyzer, such as a blood test, depending on the details of the case. Urine tests may also be offered, but typically only if the other two testing methods are unavailable.
It’s wise to contact a DUI attorney as soon as possible to help you navigate a DUI arrest without further implicating yourself.
