Sunnyvale, CA, DUI Lawyer Traffic Stop Tips:
We'd all love to drive without any risk of being pulled over, but even if you've done nothing wrong, you need to know how to navigate the situation. Below are four tips from a Sunnyvale, 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. If police see you fumbling as you try to gather these documents, they could think that you've been drinking. By keeping these documents on hand, you stop yourself from appearing inebriated.
Tip #2: Be Silent When 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. Protect yourself by keeping quiet until your lawyer arrives.
Tip #3: Refuse Voluntary 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, 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: Be Polite and Don't Argue
Arguing with the officer won't improve your case — it can end up making your case harder to defend. You should be respectful for more than its own sake, though; it also aids your defense: If you try to talk back or argue with the officer, you are giving the police more evidence, which may come back up later in court.
What Happens After a DUI Arrest in Sunnyvale?
California DUI Law allows an officer to arrest you without a BAC level over the limit, or even if you refuse to be tested at all. This is because the officer can make a subjective judgment about whether you are impaired or not, likely with field sobriety tests, then decide whether or not to arrest you based on that.
If you've been placed under arrest, the CA legal system will proceed with both a license suspension and criminal charges. In most DUI cases, here's how things will progress:
- Suspension: Your license suspension starts right away, when you're arrested – you will be given a 30-day, temporary license, and the police will take away your existing license. While you're proceeding through the system, the police are updating your records with the DMV to account for the arrest, officially suspending your license.
- Arraignment: Before you are released, you will be summoned to a court hearing, and a prosecutor will inform you of the charges against you.
- 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: It's possible to be held in jail before your trial, but that's not very likely in DUI cases. Meanwhile, your Sunnyvale DUI defense attorney will building the framework of your defense and filing motions to suppress evidence, and a "blood split" motion to have an independent lab examine your blood sample.
- Negotiations With the Prosecutor: In the midst of pretrial motions, your DUI defense attorney will speak with the Sunnyvale 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 crafting a strategy now.
- Criminal Trial: Outside of extraordinary circumstances, it's rare for a DUI case to go to trial, but if it reaches that point, we'll have a staunch defense ready for you.
- Sentencing/Sealing: Depending on how you plea or are found, you may face some form of sentence. However, if you are found not guilty or enough time has passed, we may be able to help you clean your record.
Our DUI legal experts can provide guidance for any charge, on both the criminal defense and administrative side. If you're facing a potential conviction, we have the experience to help you move towards a positive outcome!
Sunnyvale DUI: Fighting Criminal Cases vs. DMV Hearings
Sunnyvale, CA, DUI charges are special because of their dual-nature: The criminal case and the administrative case. These are handled separately by the state, but at the Law Offices of David S. Chesley, our DUI defense lawyers will fight both.
Here are things to watch out for with both cases, and how we fight to protect your justice and vehicular rights:
Sunnyvale, CA, DUI Criminal Charges
Allegedly violating DUI laws will result in criminal charges, for which you will need to go through the CA legal system.
The general court process is the same as any other criminal case – arrest, arraignment, pretrial activity, and possibly trial.
At the Law Offices of David S. Chesley, we defend your freedom and discredit the criminal accusations. We'll challenge the legitimacy of the traffic stop, argue against he officer's observations, look for weaknesses in the breathalyzer test, and see if there's anything the police missed that can exonerate you.
We have an extremely strong track record of clients who have avoided jail time in Sunnyvale, CA. Often, 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.
Sunnyvale, CA, DUI License Suspension
Even though the criminal charges may sound like the more serious matter, don't neglect the DMV and your license suspension. This suspension is automatically applied, and if you want to 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 secure a plea deal for a reduced charge, that won't (directly) affect your license suspension. Instead, the hearing is to determine if you were rightfully arrested, if your BAC was at or above 0.08, the legal limit, or, if you refused BAC tests, whether or not you were properly informed of the consequences. These hearings have serious consequences that require an expert Sunnyvale, CA, DUI lawyer to navigate. At the hearing, we'll fight the legitimacy of the stop, the arrest, and the BAC reading.
If the tenth day since the arrest has passed, though, you're out of luck. Outside of rare cases, you don't get any more chances to request that hearing. This is why it's essential to contact a Sunnyvale DUI defense attorney as soon as you can after an arrest.

DUI Defense Tactics in Sunnyvale, CA
Our Sunnyvale, CA, DUI lawyers will examine your case and suggest a defensive strategy that will maximize your chances of a positive outcome. Choosing the correct defense for your particular circumstances is essential in finding the best possible outcome. Below are some of the most effective ones.
Challenge the Legitimacy of the Arrest
If law enforcement made a mistake while conducting their investigation, then the evidence arising from that traffic stop could be invalid. This defense could be used if, for example, the officer did not observe you for the full 15-minute period required before asking you to take a breath test.
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. Our team will look into any potential procedural errors, retest when possible, and find any other mistakes law enforcement made that could exonerate you.
Challenge Field Sobriety Tests
Field sobriety tests, like 'horizontal gaze nystagmus,' are standard practice for police officers to use. But ultimately, these are judgment calls on the part of the officer. An experienced Sunnyvale, CA, DUI attorney will know how to dissect any records and look for expert analysis that will show your performance in a more favorable light.
Explain BAC With Medical Conditions
In most cases, law enforcement will follow proper procedure when testing your blood alcohol level. Let's say that this is true for your stop, and your BAC was .08 or higher. While this is can be difficult to overcome, our lawyers have more defense strategies we can pull from. 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.
