A DUI arrest in Pasadena can turn an ordinary evening into one of the most stressful experiences of your life. Whether it happened on the 210 Freeway, along Colorado Boulevard, or somewhere in Old Town, the moments after an arrest set the tone for everything that follows. Understanding the process ahead of you matters, and it matters quickly.

California’s DUI laws are strict, the deadlines are tight, and the consequences extend well beyond a fine or a night in jail. Here is what you need to know about what happens after a DUI arrest in Pasadena.

What Happens Immediately After a DUI Arrest?

After a DUI arrest in California, you will be booked, your license will be confiscated, and you face two separate legal processes.

When Pasadena police or a California Highway Patrol officer arrests you for DUI, the officer will typically confiscate your California driver’s license on the spot and issue a pink temporary license. That document serves as your driving permit for the next 30 days, but only if you act fast.

You will then be booked, processed, and either held until bail is posted or released on your own recognizance. The arresting officer submits a report to the Pasadena Courthouse, which is located at 300 E. Walnut Street and handles DUI cases for this area of Los Angeles County.

From that moment, two completely separate proceedings begin: one with the California Department of Motor Vehicles and one in criminal court.

The DMV Hearing: Your 10-Day Window

You have only 10 days from your DUI arrest to request a DMV hearing, or your license will be automatically suspended after 30 days.

This is the deadline most people miss, and missing it is costly. Under California Vehicle Code Section 13353.2, the DMV will automatically suspend your license on the 31st day after your arrest if you do not request an Administrative Per Se (APS) hearing within 10 calendar days.

Requesting the hearing does two important things: it delays the automatic suspension and gives you the opportunity to challenge the suspension itself. The hearing is conducted by the DMV’s Driver Safety Office, not a court, and the standard of proof is lower than in criminal proceedings. That said, it is still a formal legal process with real consequences.

If you are under 21 or were driving a commercial vehicle, the rules and thresholds differ under California law, so the specifics of your situation will shape your options.

Criminal Court Proceedings in Los Angeles County

DUI charges in Pasadena are prosecuted in the Los Angeles County Superior Court system, with cases typically heard at the Pasadena Courthouse.

After the arrest, the Los Angeles County District Attorney’s Office reviews the police report and decides whether to file charges. A first-offense misdemeanor DUI under California Vehicle Code Section 23152 carries penalties that can include up to six months in county jail, fines reaching $1,000 before penalty assessments (which can multiply the total significantly), probation for three to five years, a DUI program, and a license suspension.

Your arraignment is the first court appearance, where you enter a plea. From there, the case moves through pretrial motions, potential negotiations with the prosecutor, and, if no resolution is reached, a trial.

Several defenses may apply to your case, including challenges to the legality of the traffic stop, the reliability of the breathalyzer or blood test results, or the officer’s administration of field sobriety tests. California courts have well-developed case law on each of these issues, and the strength of any defense depends heavily on the specific facts of your arrest.

What Are the Penalties for a First DUI in California?

A first DUI conviction in California can result in jail time, fines, license suspension, mandatory DUI school, and years of probation.

Under California Vehicle Code Section 23538, first-time offenders placed on probation are typically required to complete a three-month DUI education program. If your blood alcohol content was 0.15% or higher, the court may order a longer program.

Beyond the formal penalties, a DUI conviction in California triggers a significant increase in auto insurance rates and creates a criminal record that appears in background checks. For professional license holders, the consequences can extend into career and licensing issues as well.

If the arrest involved an injury, a minor in the vehicle, or a BAC of 0.16% or higher, prosecutors may seek enhanced penalties under California law.

Felony DUI: When the Stakes Are Higher

A DUI becomes a felony in California if it caused injury or death, involved a minor, or if you have three or more prior DUI convictions within 10 years.

California Vehicle Code Section 23153 covers DUI causing injury, and a conviction under that section carries far more severe consequences, including potential state prison time. If you are facing felony DUI charges, the urgency of building a strong legal defense cannot be overstated.
