What Happens After a DUI Arrest in California: Hour-by-Hour Timeline

Understanding the sequence of events following a DUI arrest can help you make informed decisions and protect your rights during a stressful time.

A DUI arrest in California triggers two separate proceedings: a criminal court case and a DMV administrative action. This guide walks through what happens in the hours and days immediately following an arrest.

The Traffic Stop (Hour 0)

A DUI case typically begins with a traffic stop. California law enforcement may pull you over for any traffic violation—or if they observe driving patterns consistent with impairment such as weaving, erratic speed, or failing to maintain a lane.

What Officers Look For

  • Odor of alcohol
  • Slurred speech
  • Bloodshot or watery eyes
  • Fumbling with documents
  • Admission of drinking
  • Open containers visible

Field Sobriety Tests (Hours 0-1)

If an officer suspects impairment, they will likely request field sobriety tests (FSTs). In California, these pre-arrest tests are voluntary—you can refuse without automatic penalties. However, officers may still arrest you based on other observations.

Standard FSTs include:

1
Horizontal Gaze Nystagmus (HGN)Following a stimulus with your eyes
2
Walk-and-TurnWalking heel-to-toe in a straight line
3
One-Leg StandBalancing on one foot for 30 seconds

Chemical Testing (Hour 1)

After arrest, California's implied consent law requires you to submit to a chemical test—either breath or blood. Unlike pre-arrest FSTs, refusing this post-arrest test triggers automatic penalties including a one-year license suspension.

Breath Test

  • • Results available immediately
  • • Less invasive
  • • Cannot be independently retested
  • • May have margin of error

Blood Test

  • • More accurate results
  • • Sample preserved for retesting
  • • Results take days/weeks
  • • Can detect drugs

Booking and Processing (Hours 1-4)

Following arrest and chemical testing, you'll be transported to a local jail or police station for booking. This process includes:

Personal Information

Recording your name, date of birth, address, and other identifying details

Fingerprinting & Photos

Taking fingerprints and a booking photograph (mugshot)

Property Inventory

Cataloging and storing your personal belongings

Bail Determination

Setting bail amount based on county schedule and circumstances

Release Options (Hours 4-48)

Depending on your situation, you may be released through several methods:

Release TypeRequirementsTypical Wait
Own Recognizance (OR)First offense, ties to community4-12 hours
Cash BailPay full bail amount2-6 hours after payment
Bail BondPay 10% to bondsman2-8 hours
Cite OutMinor offense, no aggravating factors4-8 hours

Critical First 10 Days

After release, a critical deadline begins. You have only 10 days from your arrest date to request a DMV administrative hearing. Missing this deadline results in automatic license suspension.

10-Day DMV Deadline

Contact the DMV Driver Safety Office to request an Administrative Per Se (APS) hearing. This is separate from your criminal case and determines whether your license will be suspended.

The Two Parallel Proceedings

Understanding that a California DUI triggers two separate cases is essential:

Criminal Court Case

  • • Handled by District Attorney
  • • Determines guilt/innocence
  • • Potential jail, fines, probation
  • • Constitutional protections apply

DMV Administrative Action

  • • Handled by DMV
  • • Determines license status
  • • Can result in suspension
  • • Lower burden of proof
