DUI Lawyer San Francisco. If convicted, a DUI can permanently change your life for the worse. Your ability to drive isn't the only thing at risk; you're up against thousand dollar fines, years in jail, and more. In California, you're required to participate in DUI tests if you're driving. Refusal to do so is another crime, and in some cases, refusing can give you even worse penalties. And DUIs involving drugs are treated differently than those involving alcohol.
When you're up against the CA legal system, you shouldn't need to do this without help. Trying to defend yourself against the charges is a battle you need a team behind you for, which is why the Law Offices of David S. Chesley is available to protect you in San Francisco.

San Francisco, CA, DUI Lawyer Traffic Stop Tips:
Most people don't plan to be pulled over, but to successfully get through the situation when it does happen, you need to be prepared. Below are four tips from a San Francisco, CA, DUI Lawyer for you to help you get through any traffic stops unscathed:
Tip #1: Keep Your Documents Together
Your heart might start to pound as soon as the police officer asks for your ID, registration, and insurance. If police see you fumbling as you try to gather these documents, they could think that you've been drinking. When you're already prepared to give them to the officer, you avoid that risk.
Tip #2: Don't Talk If Alcohol Is Smelled
You aren't required to answer any questions if the officer says that they smell alcohol. You have the right to remain silent at all points in the legal process. Call your DUI lawyer and stay quiet until they arrive.
Tip #3: Don't Automatically Consent to Tests
In California, field sobriety tests are voluntary unless you are under the age of 21 or are on probation. This doesn't stop the officer from arresting you, but can decrease your chances of having this happen. However, you can face consequences if you refuse a blood alcohol content test after you've been arrested.
Tip #4: Be Polite and Don't Argue
Acting belligerent and uncooperative won't help — it will likely be something you regret. This isn't just something you're doing out of courtesy, though; it also helps your defense: Any time you open your mouth, whether or not the police asked you a question, you are giving the police more evidence, and depending on what you do, it could make you appear intoxicated.
What Happens After a DUI Arrest in San Francisco?
California DUI Law allows an officer to arrest you regardless of your blood alcohol level, or even if you refuse to be tested at all. Officers are able to arrest you this way because CA allows them to make subjective judgements, generally with field sobriety tests, then make judgements based on your performance.
As soon as you're arrested, the CA legal system will proceed with both a license suspension and criminal charges. After the arrest, be prepared for the following:
- Suspension: Your license suspension starts right away, when you're arrested – when arrested, you will be given a 30-day, temporary license, while the officer will keep your regular license. In the meantime, they are ensuring that the arrest is added to your DMV record, beginning the formal suspension.
- Arraignment: Sometime after arriving at the police station, you will be brought before a judge, and a prosecutor will announce what charges you're up against.
- DMV Hearing: As soon as you're released from jail, you'll need to start fighting for your license right away. This starts with arranging a DMV hearing, which you need to do within 10 days.
- Pretrial Motions: You'll likely be given bail or released on your own recognizance. Meanwhile, your San Francisco DUI defense expert will file pretrial motions, likely including some to suppress unlawfully collected evidence, and a "blood split" motion to reexamine your blood sample.
- Negotiations With the Prosecutor: Alongside pretrial motions, your DUI defense lawyer will communicate with the San Francisco district attorney to try and secure a favorable deal before a trial. But if that doesn't work, your attorney should be creating a defense now.
- Criminal Trial: It's rare that a DUI case will go to trial, but at the Law Offices of David S. Chesley, we're prepared to fight for your freedom in front of a jury, no matter what .
- Sentencing/Sealing: Depending on the result of your case, you may face sanctions. However, if you are found not guilty or enough time has passed, it's possible that your record will be eligible for sealing.
Our DUI legal experts can help you out, no matter where you are in the process, on both the criminal defense and administrative side. Whether you've just been arrested or are on the eve of your trial (or anywhere in-between), give us a call so that we can help!
San Francisco DUI: Fighting Criminal Cases vs. DMV Hearings
San Francisco, CA, DUI charges include two separate fights: The criminal case and the fight for your license. These will never be handled in the same hearing, but both cases can be fought by the same DUI defense lawyer.
Here are some things you need to know about both, and what our attorneys will do for your freedom and right to drive:
San Francisco, CA, DUI Criminal Charges
Allegedly violating DUI laws will result in criminal charges. To fight them, you'll have to go through CA courts.
Your DUI case will typically go through the same process as any other criminal charge – first, you're arrested. Second, you're informed of the charges at an arraignment. Third, you go through pretrial motions and negotiations. And finally, if it comes to it, a trial.
At the Law Offices of David S. Chesley, we defend your freedom and fight against the criminal accusations. We'll debate the legality of the traffic stop, demonstrate any present errors in the police officer's judgement, look for contaminations or errors in blood, breath, or urine tests, and see if there's anything the police missed that can present an alternate narrative.
We have an extremely strong track record of clients who have avoided jail time in San Francisco, CA. Commonly, we'll plea bargain for a reduction of the charges, typically to a wet reckless, exhibition of speed, or reckless driving charge. We'll also work to give you an alternative to jail, in the form of probation.
San Francisco, CA, DUI License Suspension
While your San Francisco criminal charges may be top of mind, don't forget about the DMV and your license suspension. This suspension goes into effect regardless of where you're at in the criminal process, and to effectively fight it, you'll need to request an administrative hearing within ten days of being arrested.
The criminal charges are not always relevant in the DMV hearing. In fact, even if you receive a "not guilty" verdict, you can still lose your license. Instead, the outcome of the DMV hearing hinges on whether or not you were legitimately arrested, if your BAC was at or above 0.08, the legal limit, or, if you refused to participate in tests, whether or not you were properly informed of the consequences. When you work with a San Francisco, CA, DUI lawyer from our firm, we'll fight the legitimacy of the stop, the arrest, and the BAC reading.
If the tenth day since the arrest has passed, though, there probably isn't a way to get your license back immediately. Outside of rare cases, you don't get an extra chance to request that hearing. This is why it's important to contact a San Francisco DUI defense lawyer right away after the traffic stop.
Punishments After a DUI Conviction in San Francisco, CA
San Francisco, CA, DUI criminal penalties can leave a mark on your record for life – while many are considered misdemeanors, you could still end up with a year in jail, or six months for a first offense.
Below, we've listed the different penalties you could be fighting against, depending on what your charges are:
| Formal DUI Charge | Jail/Prison Time | Fine |
|---|---|---|
| First Time DUI | 48 Hours to 6 Months | Up to $1,000 |
| Second Time DUI | 96 Hours to 1 Year | Up to $1,000 |
| Third Time DUI | 120 Days to 1 Year | Up to $1,000 |
| Fourth Time DUI (Felony) | 16 Months to 3 Years | Up to $1,000 |
| DUI Injury (Misdemeanor) | Up to 1 Year | Up to $1,000 |
| DUI Injury (Felony) | Up to 4 Years | Up to $5,000 |
| DUI Manslaughter (Misdemeanor) | Up to 1 Year | Up to $1,000 |
| DUI Manslaughter (Felony) | 4, 6 or 10 Years | Up to $10,000 |
On top of whatever sentence you receive in San Francisco court, you have to endure several collateral consequences, such as more expenses on your insurance and barriers between you and professional licenses.
DUIs and Immigration
DUI immigration consequences can be incredibly serious. The level of impact often depends on how many prior offenses are on your record. First-time alleged DUIs don't typically result in deportation. The bad news is that if certain circumstances apply, like DUIs causing injury or repeat offenses, you can qualify for deportation. What's worse, if H.R.875 passes, any DUI can result in removal from the country. If you are currently applying to become a U.S. citizen, even if you aren't deported, it can indefinitely pause your efforts to become a citizen.
Whether you are an immigrant citizen, are here on a work visa, or are anywhere in between, a San Francisco, CA, immigration lawyer can help you navigate the situation. At the Law Offices of David S. Chesley, we can help you in all aspects of your case: We'll explore diversion programs and plea deals that can keep a DUI off your record, fight against removal proceedings, and offer expert advice as you apply for citizenship.
After the Case: Expungement/Sealing
Whether your case ends in a conviction or an acquittal, you'll want to get back to life as normal, before the charges. However, your arrest and/or criminal record doesn't go away easily. Depending on your case outcome, there's a chance you're eligible to either expunge or seal your records. A San Francisco, CA, DUI defense lawyer from the Law Offices of David S. Chesley can also assist with this process, and give you a chance to clean your record.

DUI Defense Tactics in San Francisco, CA
Whatever type of charge you're facing, our San Francisco, CA, DUI attorneys can help you fight it. When fighting cases, here are some of the possible defenses we'll use.
Challenge the Legality of the Arrest
If law enforcement made a mistake while conducting their investigation, your case could be thrown out on legal grounds. This defense is a good option if, for example, you were not read your Miranda rights before an interrogation, anything you said could be thrown out.
Flaws in Blood, Breath, and/or Urine Tests
Chemical tests that measure the amount of alcohol in your blood, breath, or urine are strong evidence, but are not infallible. We will look into any potential procedural errors, retest when possible, and advocate for you during the discovery process to identify flaws in the state's evidence.
Challenge Field Sobriety Tests
Field sobriety tests, like 'one-leg stand,' are standard practice for police officers to use. But these tests are subjective. We will audit the test records and provide alternate explanations for your performance.
Explain BAC With Medical Conditions
Perhaps the officer properly conducted a breathalyzer test, and your BAC was .08 or higher. Even though this is harder to fight, we won't give up yet. If you have a respiratory ailment, or another medical condition, that could impact how the breathalyzer measures your BAC, we will use that as a part of your defense.
