Rancho Cucamonga, CA, DUI Lawyer Traffic Stop Tips:
We'd all love to drive without any risk of being pulled over, but knowing what to do if you are in a traffic stop can help you avoid an arrest. Here are four tips from a Rancho Cucamonga, CA, DUI Lawyer for you that will guide you through your next traffic stop:
Tip #1: Be Prepared With Your Documents
After being pulled over, but before the police officer approaches your car, grab your license, vehicle registration, and insurance documentation. With an officer staring you down, asking for documents you may not have had to touch in months, it's easy to get flustered. But if you already have them ready, you avoid that risk.
Tip #2: Don't Talk If Alcohol Is Smelled
If either the officer alleges that they smell alcohol, or you can smell alcohol yourself, don't answer any questions. You have Fifth Amendment protections at all points in the legal process. Call your DUI lawyer and stay quiet until they arrive.
Tip #3: Refuse Voluntary Tests
California does not require the majority of people to participate in field sobriety tests, and in fact, you can often refuse without penalty. The two main exceptions are if you are under the age of 21, and/or if you are on probation. If you haven't been arrested, you can decline to participate. However, if you have been arrested and refuse a blood or breath test, your license will be suspended.
Tip #4: Treat the Officer Respectfully
Resisting the police won't help — it will likely be something you regret. This is about more than just avoiding an arrest in the short term; it also helps your defense: When you resist or act disrespectfully, you are giving the police more evidence, which may help justify an arrest.
What Happens After a DUI Arrest in Rancho Cucamonga?
California DUI Law allows an officer to arrest you even if you BAC is below .08, or even if you don't undergo any tests at all. Officers are able to arrest you this way because CA allows them to make subjective judgements, likely utilizing field sobriety tests, then make arrests based on the results.
If you've been placed under arrest, the CA legal system starts moving towards both a license suspension and criminal charges. You can expect the following steps to play out in your case:
- Suspension: Your license suspension can begin as soon as you're arrested – at that time, you will be given a 30-day, temporary license, while the officer will keep your regular license. While you're processing this, they are informing the DMV about the arrest, beginning the formal suspension.
- Arraignment: At some point when you're in jail, you will attend a hearing, and a prosecutor will read out the allegations that you are formally being charged with.
- DMV Hearing: Independant of the criminal charge process, you'll have 10 days after the arrest to contact the DMV for a hearing.
- Pretrial Motions: It's possible to be held in jail before your trial, but that's not very likely in DUI cases. In the meantime, your Rancho Cucamonga DUI defense attorney will building the framework of your defense and filing motions to suppress evidence, and a "blood split" motion to reexamine your blood sample.
- Negotiations With the Prosecutor: While working through pretrial motions, your DUI defense lawyer will work directly with the Rancho Cucamonga district attorney to avoid a trial with a plea deal that protects you. But if it does go to trial, your attorney should be building a defense now.
- Criminal Trial: Outside of extraordinary circumstances, it's rare for a DUI case to go to trial, but just in case it does, our team always crafts a trial-ready defense.
- Sentencing/Sealing: Depending on how your case turns out, 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 provide you with advice on the best way to move forward, on both the criminal defense and bureaucratic 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!
Rancho Cucamonga DUI Allegations and Criminal Cases vs. DMV Hearings
Rancho Cucamonga, CA, DUI charges are always a two-pronged challenge: The criminal case and the DMV case. These are handled separately by the state, but a leading DUI defense attorney from our offices will fight for you in both cases.
Here are important factors for both case types, and insights into how we protect your freedom and right to drive:
Rancho Cucamonga, CA, DUI Criminal Charges
Allegedly violating DUI laws will result in criminal charges. To fight them, you'll have to go through CA courts.
The general court process is the same as any other criminal case – after an arrest, you're formally charged in an arraignment, go through pretrial motions/negotiations, and can eventually go to trial.
At the Law Offices of David S. Chesley, we craft a staunch defense and dissect the accusations. We'll debate the legality of the traffic stop, argue against he officer's observations, look for contaminations or errors in blood, breath, or urine tests, and hunt for other evidence that can exonerate you.
We know what it takes to keep DUI defense clients out of jail in Rancho Cucamonga, CA. For several cases, we'll negotiate a plea deal to reduce the charges, typically to a wet reckless, exhibition of speed, or reckless driving charge. We'll also argue for probation to maintain your freedom.
Rancho Cucamonga, 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 doesn't wait for your criminal case, and to fight it, you'll need to request an administrative hearing within ten days of your arrest.
When you go through the DMV hearing, your criminal charges may not be a major focus. In fact, you can lose your license regardless of the outcome of the criminal case. Instead, the focus of this hearing is whether or not you were rightfully arrested, if your BAC was at or above 0.08, the legal limit, or, if you refused to blow, whether or not you were properly informed of the consequences. When you hire us, we'll question the legitimacy of the stop, the arrest, and the BAC reading.
After ten days, though, you're out of options. Outside of rare cases, you don't get an extra chance to schedule that hearing. This is why it's important to contact a Rancho Cucamonga DUI defense lawyer without delay after an arrest.

DUI Defense Tactics in Rancho Cucamonga, CA
When you work with the Law Offices of David S. Chesley, your Rancho Cucamonga, CA, DUI attorney will draw from years of experience with effective defense strategies. When fighting cases, here are some of the possible defenses we'll use.
Contest the Legitimacy of the Arrest
If the arresting officer failed to obey the rules for investigating a DUI, we can argue for your case to be dismissed. This defense is effective if, for example, the police officer pulled you over without probable cause, the entire traffic stop could be made invalid.
Flaws in Chemical Tests
If your case is centered on a BAC test that put you over the legal limit, that can sound impossible to overcome. But it isn't. Our team will look into any potential procedural errors, retest in some cases, using a "blood-split" motion, and analyze the state's case to see if there was an error made in how your evidence was processed.
Challenge Field Sobriety Tests
Field sobriety tests, like 'horizontal gaze nystagmus,' are a widely-recognized way of evaluating somebody's level of impairment. But field sobriety tests are not objective measures of whether you're safe to drive or not. An experienced Rancho Cucamonga, CA, DUI attorney will know how to dissect any records and show whether or not you were fairly judged.
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 properly conducted BAC tests are hard to disprove, you do still have viable defense strategies. Medications and health conditions can create false positives – even just over-the-counter cold medicine often contain alcohol, which can linger in your mouth, impacting the test.
