A DUI arrest triggers two separate processes that run on different timelines. One happens in criminal court. The other involves the DMV. Many people focus entirely on the criminal case and miss a deadline that costs them their license. Understanding both tracks helps you protect yourself on all fronts.
The Two Cases You’re Actually Facing
When an officer arrests you for DUI, two things happen simultaneously. The district attorney’s office reviews the case for potential criminal charges. And the DMV initiates an administrative action to suspend your driving privileges. Our friends at Seyb Law Group regularly remind clients that these are completely independent proceedings with different rules, different burdens of proof, and different consequences.
The criminal case determines whether you’re guilty of a crime and what sentence you’ll face. The DMV case determines whether you keep your license. You can win one and lose the other.
The DMV Hearing and the 10 Day Deadline
This is where people make their first mistake. When the officer takes your license, they hand you a pink temporary license. That document also serves as notice that your license will be automatically suspended in 30 days unless you request a hearing.
You have exactly 10 days from your arrest to request a DMV hearing. Miss that deadline and you waive your right to challenge the suspension.
A DUI lawyer can request this hearing on your behalf and represent you at the proceeding. The hearing focuses on three questions:
- Did the officer have reasonable cause to believe you were driving under the influence
- Were you lawfully arrested
- Was your blood alcohol level 0.08% or higher at the time of driving
If the DMV rules against you, your license gets suspended. The length depends on your record and whether you refused chemical testing.
The Criminal Court Process
The criminal case begins with an arraignment, usually within a few weeks of arrest. At arraignment, you hear the formal charges and enter a plea. Most people plead not guilty at this stage to preserve their options.
DUIs are prosecuted under Vehicle Code Section 23152, which contains multiple subsections. Prosecutors typically charge both 23152(a), driving under the influence, and 23152(b), driving with a BAC of 0.08% or higher. These are separate offenses, though they arise from the same conduct.
After the arraignment, your attorney reviews the discovery, including police reports, breath or blood test results, calibration records, and any body camera or dashcam footage. Weaknesses in the evidence create opportunities for negotiation or dismissal.
Potential Penalties for a First DUI
A first-offense DUI is typically charged as a misdemeanor. Under California Vehicle Code Section 23536, penalties can include:
- Base fines of $390 to $1,000, plus penalty assessments that typically bring total costs to $1,500 or more
- License suspension
- Possible jail time of 48 hours to six months, though often avoided or minimized on first offenses when probation is granted
Aggravating factors change the calculus. A BAC significantly above 0.08%, an accident with injuries, excessive speed, or having a minor in the vehicle can all increase penalties substantially.
A lawyer who handles these cases regularly understands how local prosecutors and judges typically approach first offenses versus aggravated cases.
Prior DUIs Make Everything Worse
Most states look back 10 years when counting prior DUI convictions. A second offense within that window means mandatory jail time, longer license suspension, and an 18-month education program. A third offense can be charged as a felony.
Fourth and subsequent offenses are always felonies, carrying potential state prison time.
Taking Action
Attorneys understand how much a DUI charge threatens your license, your job, and your future. The 10-day DMV deadline doesn’t wait, and neither should you. If you’ve been arrested for DUI, reach out to a lawyer to discuss your case and learn what options may be available.
