Facing the possibility of a driving under the influence (DUI) charge can leave you feeling overwhelmed and unsure of how to proceed. DUI convictions carry heavy sanctions that could affect you for many years. A Rancho Cucamonga DUI lawyer can guide you through the DUI process, gather evidence for your defense, and make sure that your rights have not been violated. A skilled DUI lawyer can also negotiate on your behalf for reduced charges.
When you hire a DUI lawyer, you want someone who thoroughly understands the legal process and how to negotiate and litigate for the most favorable outcome for their client. As a former prosecutor, Attorney Kolacia understands how prosecutors build DUI cases and how plea agreements are used when prosecutors have insufficient evidence to secure a conviction. Our team understands how to use our experience in your favor.
Driving while under the influence of alcohol is one of the leading causes of collisions, injuries, and fatalities in the United States. Many states, like California, have enacted stiff penalties for alcohol-related traffic accidents and drunk driving because of the possibility of severe consequences. In the United States, there were 12,429 alcohol-impaired fatalities from crashes in 2023. These deaths accounted for 30% of all crash-related fatalities.
In California in 2023, there were 1,355 alcohol-involved fatalities. The number of alcohol-involved fatalities has increased 55% in California from 2014 to 2023. In Rancho Cucamonga, also during 2023, there were a total of 66 alcohol-involved crashes that caused injuries or death. Officers arrested 173 drivers under suspicion of DUI.
DUI cases are handled in the San Bernardino County Superior Court system. Both misdemeanor and felony cases for residents of Rancho Cucamonga are heard at the Rancho Cucamonga Courthouse. Hearings for the Department of Motor Vehicles (DMV) to handle driver’s license suspensions are held at the San Bernardino Driver Safety Office in San Bernardino.
During a traffic stop, or following a traffic accident, officers who suspect a driver may be under the influence of alcohol or drugs may engage in field sobriety testing or require chemical testing to check the driver’s blood alcohol concentration (BAC). Illegal BAC limits vary, but include:
California Vehicle Code 23152 outlines which behaviors are considered illegal when a driver is under the influence of alcohol or drugs. Under these guidelines, several different types of DUI charges can be filed against a driver. The different types of DUI include:
Any DUI charge can result in serious penalties, including a criminal record and adverse points on your driving record. In addition to large fines and fees, jail time, probation, and educational classes could be required. Serious offenses could result in long license suspensions or the requirement to install an IID. An experienced Rancho Cucamonga DUI attorney can help you build a defense and achieve a more favorable outcome.
When arrested for a possible DUI, aggravating factors could result in a more serious charge or prevent your defense attorney from successfully negotiating reduced charges or lighter penalties. Even a first offense DUI charge can be elevated if aggravating factors are present. Common aggravating factors include:
The National Highway Transportation Safety Administration (NHTSA) issues police procedures for DUI field sobriety tests (FSTs). California allows refusal of FSTs without fear of penalty. Dozens of FSTs exist, but the NHTSA only recognizes three as valid and reliable for use. These three standardized FSTs are:
In addition to the three standardized FSTs, officers may use non-standardized FSTs when determining if there is probable cause for a DUI arrest. Common non-standardized FSTs include:
The NHTSA considers standardized FSTs as accurate indicators of intoxication, but there are many reasons why someone might fail an FST that are not alcohol or drug-related. Considerations when administering FSTs include:
There are numerous reasons why someone could fail an FST when they are not over the legal BAC limit. These reasons include:
Unlike field sobriety testing, you cannot refuse chemical testing without legal penalties. Implied consent laws state that licensed drivers who drive on public roads have given implied consent to law enforcement to engage in chemical testing if there is probable cause to warrant such a test. The person being tested has the right to choose whether to take a blood or breath test.
Refusing chemical testing can result in fines, jail time, and an automatic one-year license suspension. When a chemical test is required, officers must inform the person being tested of the penalties for refusing. If these penalties are not disclosed, the results of the chemical test could be excluded as evidence. A DUI attorney can help determine if testing was administered legally and correctly.
When you are arrested for a suspected DUI, the DMV is automatically notified. If you don’t take action, your license is automatically suspended 30 days after the initial arrest. To prevent this suspension, you have only 10 days to request a DMV hearing. You should have legal representation during this hearing. The DMV hearing process involves:
The results of the DMV hearing can be used in the criminal DUI case. If you lose your DMV hearing, or do not request one, and your DUI case is dismissed or you are acquitted, your driving privileges may not be automatically reinstated. You may have to petition to have your suspension reversed.
DUI laws can be complex, and they change frequently. A DUI attorney can evaluate your case and determine which defense strategy fits the specific facts of your case. An effective defense strategy could result in the charges being dismissed or in successfully negotiating for reduced charges or lighter penalties. Common defense strategies include:
A: There is no standard cost to hire a DUI lawyer in California, but most follow one of two standard billing methods. Some lawyers charge a flat fee for a specific charge. Straightforward cases typically cost less than more complex cases. Conversely, some lawyers charge based on an hourly rate. The more hours it takes to defend your case, the higher the final cost may be. Some also charge an additional trial fee if the case proceeds to trial.
A: Yes, it is worth it to hire a DUI lawyer in California. DUI penalties can be severe, even if it is your first offense. Hiring a defense lawyer can be expensive, but the high cost of a DUI conviction, coupled with the personal and professional restrictions that can occur, makes it worth the investment. You are more likely to secure a plea agreement that could allow for reduced charges when working with a DUI lawyer.
A: In California, when a DUI arrest is made, the person who was arrested has 10 calendar days to request an administrative hearing with the DMV to challenge the automatic suspension of their driver’s license. If this 10-day rule is not followed, you lose the right to contest the suspension even if the charges are later dismissed or you are acquitted. At the hearing, you can request that the suspension be paused until the outcome of your case.
A: Yes, it is possible to get DUI charges reduced in California. Depending on the BAC level, prior DUI history, and the strength of the prosecution’s evidence, several different reductions could be negotiated. A common reduced charge is a wet reckless, which is a reckless driving charge involving alcohol or drugs. It could also be possible to get the charge reduced to a dry reckless or an exhibition-of-speed charge.

So, I used to live in The San Bernardino Mountains in SoCal about 15-20 years ago. I now live in TN. I had an opportunity to foster my grandson here. In the process of being approved to be a foster parent, I was fingerprinted and had to consent to a background check. I did this willingly believing with all my heart that I would be cleared. Much to my shock, however, it came back that I had an active warrant in CA for failure to appear on driving without a license. Now, the reason that this shocked me was because…

Daniel Kolacia at the Kolacia Law Firm did exactly what he said he would. Other big name companies would give me the run around and tell me that it couldn't be done. He got my Felony reduced to a misdemeanor. He worked with me through all steps and once I got him everything he requested the court date was set.

I have always been skeptical of lawyers until I spoke with Daniel Kolacia. With just his introduction he set me at ease and throughout the whole process made me feel more comfortable than I've ever felt dealing with the law. He never gave up on me, and tells me his commitment comes from a higher place of reverence. I am so happy with the outcome that I not only consider him as my lawyer but I consider him as a friend. Thank you Kolacia law for everything that you have done.
Mr. Kolacia defended my case honestly and better than I thought possible. I truly thought I was going to jail. He always advised me logically and with empathy to my personal situation. Always referring to me, with the choice in direction on how to proceed. Regardless of my decision, he defended me vigorously. The outcome of the case was more than fare. Even after the sentencing he still consults with me. Daniel Kolacia did not sugar coat any bad or good news regarding my case. I hope more people get the same professional help that I received.
