Drunk driving cases in Santa Rosa, California, are governed primarily by California state law and enforced by local agencies such as the Santa Rosa Police Department and the California Highway Patrol. A driving-under-the-influence matter can involve both criminal court proceedings and administrative actions by the California Department of Motor Vehicles. Criminal charges focus on violations of criminal statutes, possible jail time, fines, probation, and criminal records. Administrative proceedings at the DMV can lead to a license suspension independent of the criminal case. This guide explains the basics, common issues, and practical next steps for people facing drunk driving concerns in Santa Rosa, California, United States.
Facing a drunk driving allegation can have immediate and long-term consequences. You may need a lawyer if any of the following apply:
- You were arrested on suspicion of driving under the influence, even for a first-time offense. An attorney can advise on both the criminal case and the DMV administrative process.
- You registered a high blood alcohol concentration, for example .15% or higher, or you refused a chemical test. High BAC levels and refusals often lead to enhanced penalties.
- You were involved in an accident that caused injury or property damage. Cases involving injury or death can become felony matters with far more severe penalties.
- You are a commercial driver or hold a professional license. Lower BAC limits and career-impacting consequences can apply.
- A minor was in the vehicle or you face child endangerment allegations. Special enhancements and mandatory penalties often apply.
- You want to challenge the DMV administrative license suspension and need help requesting and preparing for the DMV hearing within tight deadlines.
- You are concerned about immigration consequences, employment impact, or record sealing after conviction. Specialized advice can protect collateral interests.
Key aspects of Santa Rosa and California drunk driving law to understand include:
- Legal Blood Alcohol Concentration - For most drivers, a 0.08% blood alcohol concentration or greater is the legal threshold for DUI. For commercial drivers the limit is 0.04% and for drivers under 21 there is a zero-tolerance approach where any detectable alcohol can result in penalties.
- Criminal vs Administrative Proceedings - An arrest can lead to two separate processes. Criminal charges proceed in Sonoma County Superior Court. Separately, the California DMV handles administrative license actions that can suspend driving privileges unless you timely request a hearing.
- Implied Consent and Chemical Tests - California has an implied consent law that requires drivers lawfully arrested for DUI to submit to chemical testing of breath or blood. Refusal can lead to an automatic administrative suspension and separate criminal penalties.
- Field Sobriety Tests and Preliminary Screening - Officers commonly use standardized field sobriety tests and preliminary breath screening devices at the scene. Results can be used as evidence, but they can also be challenged for accuracy and officer conduct.
- Penalties by Offense Type - A first-time misdemeanor DUI can include fines, probation, mandatory alcohol education, possible jail up to six months, and a license suspension. Enhanced penalties apply for high BAC, prior DUI convictions, causing injury or death, and having a child passenger under 14. Repeat or serious cases may be charged as felonies.
- DMV Timelines - After arrest, you typically have 10 calendar days from the date of arrest to request a DMV administrative per se hearing to contest the license suspension. Missing this deadline usually results in automatic suspension.
- Ignition Interlock Devices and Reinstatement - Courts or DMV may require an ignition interlock device as a condition for restricted driving privileges or license reinstatement in certain cases. Requirements depend on the offense and prior history.
Stay calm and cooperate with lawful instructions at the scene. You have the right to remain silent about details beyond identity information. Ask for an attorney as soon as you can. Note the arrest date and request a DMV hearing within 10 days if you wish to challenge the administrative license action. Do not discuss the facts on social media or with anyone other than your attorney.
After an arrest for DUI, the officer may take your license and issue a temporary license for 30 days. The DMV will notify you of an intended suspension. You must request an administrative per se hearing within 10 days of the arrest to contest the suspension. A lawyer can help request the hearing, gather evidence, and prepare legal arguments to challenge probable cause for the stop or the accuracy of chemical tests.
Refusing a chemical test after a lawful DUI arrest can trigger an automatic administrative suspension and additional criminal penalties for refusal. In serious cases, police may seek a warrant to obtain a blood sample. Refusal is a serious matter and often makes defending both the DMV case and criminal charges harder, so consult a lawyer quickly.
Penalties for a first misdemeanor DUI may include fines, possible jail time up to six months, probation, mandatory alcohol education programs of several months, and a license suspension. Actual penalties depend on BAC level, presence of minors, property damage or injury, and criminal history. Judges and prosecutors may offer alternative sentences such as diversion programs in appropriate cases.
If the DUI incident caused injury or death, the charges can be far more serious and can include felony counts. Penal consequences increase substantially and can involve longer jail or prison terms, larger fines, restitution to victims, and long-term collateral effects. You should retain experienced counsel immediately if injuries are alleged.
Yes. California DUI laws cover impairment by alcohol, illegal drugs, prescription medication, and some over-the-counter medications. Prosecutors may use field sobriety tests, officer observations, toxicology results, and expert testimony to show impairment. If you take prescription medication, you should preserve medical records and consult a lawyer about defenses.
Possibly. A DUI can affect employment, especially for occupations that require driving, public safety roles, or professional licensing. Commercial drivers face stricter BAC rules and mandatory reporting in many professions. If you have a professional license, notify and get advice from an attorney about mandatory disclosures and potential administrative consequences.
Drivers under 21 are subject to California's zero-tolerance rules. Any detectable alcohol can lead to license suspension, fines, and mandatory education. Criminal charges are possible if the underage driver is found to be impaired. Penalties for underage drivers can also affect insurance and future driving privileges.
In many cases, a misdemeanor DUI conviction may be eligible for expungement under California Penal Code 17(b) once probation is successfully completed. Expungement can set aside the conviction for most purposes, but it does not always restore rights automatically or remove administrative consequences. Felony DUI convictions and certain severe outcomes may be ineligible. Consult a qualified attorney about eligibility and procedure.
Attorney fees vary widely based on experience, case complexity, and whether the matter goes to trial. Fees could range from a few thousand dollars for straightforward representation to much more for complex or felony cases. Choose a lawyer who focuses on DUI defense, understands Sonoma County courts, has trial experience, and provides a clear fee agreement and communication plan. Many attorneys offer an initial consultation to review the case.

Step 6 - Prepare for both processes: Expect both a criminal case and a DMV administrative matter. Your attorney can coordinate defenses across both processes and pursue diversion, plea negotiations, or trial as appropriate.
