San Francisco, CA, DUI Lawyer Traffic Stop Tips:
You may be a careful driver who doesn't violate any traffic laws, but knowing how to handle the situation is important for all San Francisco, CA, residents. Below are four tips from a San Francisco, CA, DUI Lawyer for you to help you get through any traffic stops unscathed:
Tip #1: Have Your Documents Ready
Keep your license, insurance card, and vehicle registration together and easily accessible. Dropping them or failing to find them could just be a result of stress, but it can give the impression that you're impaired. But if you don't need to search for them, you stop yourself from appearing inebriated.
Tip #2: Don't Talk If Alcohol Is Smelled
You never need to answer a question that might incriminate you. You have the right to remain silent during any form of questioning. Trying to explain away the smell of alcohol will probably just get you in more trouble.
Tip #3: Refuse Voluntary Tests
In California, field sobriety tests are voluntary unless you are under the age of 21 or are on probation. You can still be arrested if the officer believes you've broken the law, but you're giving them less evidence this way. However, this isn't the case for every test; if you're already in custody and are asked to perform a breath or blood based test, California law does require you to participate.
Tip #4: Respect the Law Enforcement Officer
Resisting the police won't help — it will come back to bite you. This doesn't just help you get through the traffic stop; it also benefits your defense: By acting out or arguing, you are giving the police more evidence, which could contribute to their probable cause to arrest you.
What Happens After a DUI Arrest in San Francisco?
California DUI Law allows an officer to arrest you even if you blow below the legal limit, or even if you aren't tested at all. Officers are able to arrest you this way because CA allows them to make subjective judgements, likely via field sobriety tests, then make judgements based on how you do.
As soon as you're arrested, the CA legal system automatically begins the process for both a license suspension and criminal charges. In most DUI cases, here's how things will progress:
- Suspension: Your license suspension effective immediately after your arrest – at that time, you will be given a 30-day, temporary license, and your actual license will be taken. In the meantime, they are ensuring that the arrest is added to your DMV record, at which point, you're officially facing a license suspension.
- Arraignment: After your arrest and before your release, you will be brought before a judge, and a prosecutor will list out the laws you're accused of breaking.
- DMV Hearing: While all of the criminal proceedings are going on, you'll want to set up a DMV hearing within 10 days to protect your license.
- Pretrial Motions: In most DUI cases, you'll be released in some capacity pending a trial. In the meantime, your San Francisco DUI defense lawyer will building the framework of your defense and filing motions to review the arrest footage, and a "blood split" motion to reexamine your blood sample.
- Negotiations With the Prosecutor: Alongside pretrial motions, your DUI defense attorney will speak with the San Francisco district attorney to find a positive outcome for you that avoids a trial through a plea deal. But if you end up on trial in front of a judge, your attorney should be creating a defense now.
- Criminal Trial: It's unlikely that your DUI case will go to trial, but we don't count on that possibility and will be ready if it does.
- Sentencing/Sealing: Depending on the result of your case, you may face consequences. However, if you are found not guilty or enough time has passed, you may be eligible to have your record sealed.
Our DUI legal experts can help you out, no matter where you are in the process, on both the criminal defense and license side. If you need help today, our team has the knowledge to guide you forward!
San Francisco, CA, DUI Differences: Criminal Cases vs. DMV Hearings
San Francisco, CA, DUI charges are special because of their dual-nature: The criminal case and the driver's case. Different CA organizations cover each of these aspects, but both cases can be fought by the same DUI defense lawyer.
Here are some things you need to know about both, and ways we defend your justice and license:
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.
If you're familiar with the process of other criminal charges, DUI cases follow the same format – 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 build your defense and fight against the accusations. We'll challenge the legitimacy of the traffic stop, argue against he officer's observations, look for weaknesses in the breathalyzer test, and hunt for other evidence that can tell a different story.
The vast majority of our DUI clients in San Francisco do not receive any jail sentence. Frequently, we'll work out a plea for reduced charges, typically to a wet reckless, exhibition of speed, or reckless driving charge. We'll also avoid jail time with a probation sentence.
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 automatically, and to effectively fight it, you'll need to request an administrative hearing within ten days of being arrested.
It's typical for the criminal case to be, by and large, separate from 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 rightfully arrested, if your BAC was at or above 0.08, the legal limit, or, if you refused alcohol tests, whether or not you were properly informed of the consequences. When you work with us, we'll challenge the legitimacy of the stop, the arrest, and the BAC reading.
After ten days, though, you'll likely have to endure the suspension. Outside of rare cases, you don't get a second chance to set up that hearing. This is why it's critical to contact a San Francisco DUI defense attorney as soon as you can after the traffic stop.

DUI Defense Strategies in San Francisco, CA
If you want to craft an effective defense strategy, our San Francisco, CA, DUI lawyers are here to help. Choosing the correct defense for your particular circumstances is essential in finding the best possible outcome. Below are some of the most effective ones.
Contest the Legitimacy of the Traffic Stop
If the police did not follow proper procedure while stopping and examining you, we can argue for your case to be dismissed. This defense is a good option if, for example, the officer did not observe you for the full 15-minute period required before asking you to take a breath test.
Show Issues With Chemical 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 in some cases, using a "blood-split" motion, and look for any issues in how the evidence was handled.
Challenge Field Sobriety Tests
Field sobriety tests, like 'one-leg stand,' are a normal part of the process when police are evaluating if someone is driving intoxicated or not. But you can still challenge them – they are not ironclad proof of guilt. We will examine the evidence and look for expert analysis that will show your performance in a more favorable light.
Explain BAC With Medical Conditions
Perhaps the officer properly conducted a breathalyzer test, and your BAC was over the legal limit. While this is can be difficult to overcome, it's not the end of your case. If you have certain medical conditions, those can cause false positives. For example, some inhalers can artificially raise the amount of alcohol in your breath, depending on how they are used.
