A DUI arrest in San Diego starts two separate cases at once: a criminal case in court and a license case with the DMV. The DMV side moves fast, you have only 10 days to protect your license, and most people miss it. A San Diego DUI attorney’s first job is to keep both from running away from you.
This guide explains what to do after a DUI arrest, the penalties California law allows, the 10-day DMV deadline, and how a defense attorney can change the outcome.
What should you do after a DUI arrest in San Diego?
Request your DMV hearing within 10 days and speak to a DUI attorney before you talk to anyone else about the case. Those two steps protect your license and your defense while the details are still fresh.
- Request the DMV hearing within 10 days of the arrest, or your license is automatically suspended.
- Write down everything you remember: the stop, the tests, what was said.
- Do not discuss the case with anyone but your attorney.
- Keep every document the officer gave you, including the pink temporary license.
Why does the 10-day DMV deadline matter so much?
Because a DUI arrest triggers an automatic license suspension unless you request a DMV hearing within 10 days. This administrative case is separate from court, and missing the window forfeits your best chance to keep driving. The California DMV explains this Administrative Per Se process.
The DMV hearing is winnable. It is a chance to challenge the stop and the evidence, and a successful hearing can save your license even while the court case continues. This is one of the biggest reasons to call an attorney immediately, not after the deadline passes.
What is the difference between the DMV hearing and the criminal court case?
They are two separate cases with two separate outcomes: the DMV hearing decides your driving privilege, and the criminal court case decides the DUI charge, penalties, and your record. They run on different timelines, and you can win one and lose the other, which is why both need attention from the start.
| DMV hearing | Criminal court case | |
|---|---|---|
| Decides | Your driver’s license | Criminal penalties and your record |
| Deadline | Request within 10 days of arrest | Court date set after the arrest |
| Possible outcome | License saved or suspended | Dismissal, reduction, or conviction |
| Who decides | A DMV hearing officer | A judge or jury |
People often assume that beating one case ends the other. It does not. A dismissal in court does not automatically restore your license, and a favorable DMV hearing does not erase the criminal charge. Handling both together, on their separate clocks, is a core part of what a DUI attorney does.
What is the legal blood alcohol limit in California?
The legal limit is 0.08% blood alcohol concentration for most drivers, but lower limits apply to some. Under California Vehicle Code § 23152, it is unlawful to drive with a BAC at or above these thresholds.
| Driver | BAC limit |
|---|---|
| Most drivers (21 and over) | 0.08% |
| Commercial drivers | 0.04% |
| Drivers under 21 | 0.01% (zero tolerance) |
You can also be charged even below 0.08% if an officer believes alcohol or drugs impaired your driving, which is why the specific facts of the stop matter so much.
Can you refuse a breath or blood test in California?
You can refuse, but California’s implied consent law makes refusal expensive. By driving in the state you have already agreed to chemical testing if you are lawfully arrested for DUI, under California Vehicle Code § 23612.
Refusing the required post-arrest breath or blood test usually triggers a longer license suspension and can be used against you in court, on top of the DUI charge itself. There is an important distinction, though: if you are 21 or older and not on DUI probation, you can generally decline the preliminary roadside breath test (the handheld device before arrest) without that penalty. The mandatory test is the one after a lawful arrest. Because the rules change before and after arrest, this is exactly the kind of detail a DUI attorney untangles when reviewing your stop.
What are the penalties for a DUI in California?
A first-offense DUI is usually a misdemeanor, and penalties can include fines, license suspension, DUI school, probation, and up to six months in county jail under the California Vehicle Code. Penalties rise sharply with prior offenses, a high BAC, an accident, or injuries.
- Fines and court fees, which add up well beyond the base fine.
- License suspension, with possible restricted-license options.
- DUI education program (often three to nine months).
- Probation, typically three to five years.
- Jail, up to six months for a first misdemeanor offense, more for repeat or aggravated cases.
A DUI causing injury can be charged as a felony, with far more serious consequences. The exact exposure depends on your record and the facts, so get them reviewed early. Two people charged with the same offense can end up in very different places depending on how their case is handled, which is why the details are worth taking seriously from day one. A quick guilty plea often costs far more, in license time and long-term consequences, than it seems to save.
How do prior DUIs change the penalties?
California counts prior DUIs within a 10-year window, and each prior sharply raises what you face. A current charge is always measured against your record, so two people arrested the same night can face very different outcomes.
- Second DUI within 10 years: longer license suspension, mandatory jail time, and a longer DUI program.
- Third DUI within 10 years: still heavier penalties, a longer program, and a longer suspension.
- Fourth DUI within 10 years, or any DUI causing injury: can be charged as a felony.
- Ignition interlock device (IID) is required in many repeat cases before you can drive again.
Because the look-back period and the counting of priors are technical, an accurate review of your history is one of the first things a defense attorney does. Sometimes a prior can be challenged, which changes everything about the current case.
How can a San Diego DUI attorney help your case?
A San Diego DUI attorney can challenge the traffic stop, the field sobriety and breath tests, and the handling of your blood sample, then use those weaknesses to reduce or dismiss charges. Many DUI cases turn on procedure, not just the BAC number.
- The stop. Did the officer have a lawful reason to pull you over?
- The testing. Were breath and field sobriety tests done correctly?
- The blood sample. Was it drawn, stored, and analyzed properly?
- The negotiation. Can the charge be reduced, or resolved without the worst penalties?
Beyond the courtroom, a DUI attorney manages the pieces most people never see: filing the DMV hearing request on time, gathering the police report and lab records, enrolling you in the right DUI program, and making sure no quiet deadline slips past. That organized, early handling is often what separates a manageable outcome from a costly one.
Even when the evidence is strong, an experienced attorney often reduces the penalties, protects your license, and keeps a first mistake from defining your record. You can review the court process on the California Courts self-help site.
How do you get help after a San Diego DUI?
Move quickly, because the 10-day DMV clock is already running. An early call protects your license and gives your defense the most room to work. The first days after an arrest are when evidence is easiest to preserve and when the most options are still open, from the DMV hearing to how the charge itself is approached. Waiting rarely helps, and it can quietly close doors you did not know were there.
Do not face a DUI charge alone or wait until the deadline passes. Call The Law Firm of Howard Williams at (619) 558-5444 to book a consultation, or schedule an appointment online. You can also contact our San Diego office right away.

You have 10 days from the date of arrest to request a DMV hearing. Miss it and your license is suspended automatically, separate from anything that happens in court.

A first DUI is usually a misdemeanor. It can become a felony if it involved injury to another person or if you have certain prior convictions.
Can a DUI charge be reduced or dismissed?
Yes, it happens. Depending on the facts, charges can be reduced or dismissed when the stop, the testing, or the evidence handling had problems. An attorney reviews those details for defenses.
Will I lose my license after a DUI in San Diego?
Not necessarily. Requesting a DMV hearing within 10 days can protect your license, and restricted-license options may let you keep driving to work and DUI school in many cases.
Do I really need a lawyer for a first DUI?
A first DUI carries lasting consequences for your license, record, and finances. A DUI attorney can protect your license, challenge the evidence, and often reduce the penalties, which is hard to do on your own.
