In California, driving under the influence is primarily governed by Vehicle Code Sections 23152(a) and 23152(b). Under these statutes, it is illegal to operate a motor vehicle while under the influence of alcohol or drugs, or with a blood alcohol concentration (BAC) of 0.08% or higher. According to the California Office of Traffic Safety[1], DUI arrests remain a significant public safety concern throughout the state, with thousands of arrests occurring annually in Los Angeles County alone.
For most first-time offenders and those with no aggravating circumstances, DUI charges are filed as misdemeanors rather than felonies. However, even a misdemeanor DUI is a serious criminal offense with significant consequences. Understanding the specific charges you face is the first step in building an effective defense.
Vehicle Code Section 23152(a) makes it unlawful for any person who is under the influence of any alcoholic beverage to drive a vehicle. This statute focuses on your actual impairment rather than a specific BAC level. The prosecution must prove that alcohol affected your ability to drive with the caution and care of a sober person under similar circumstances.
This means you can be convicted of DUI under 23152(a) even if your BAC was below 0.08%, if the prosecution can demonstrate that you were impaired by alcohol. Conversely, even with a BAC above 0.08%, you may be acquitted under this section if the evidence shows you were not actually impaired.
Vehicle Code Section 23152(b) creates what is known as a “per se” DUI offense, making it unlawful to drive with a BAC of 0.08% or higher, regardless of whether you were actually impaired. This means that if chemical testing shows your BAC was at or above the legal limit, you can be convicted even if you were driving perfectly and showed no signs of impairment.
Many DUI arrests in Pomona result in charges under both 23152(a) and 23152(b), giving prosecutors two different theories under which to pursue a conviction. However, you can only be convicted and punished under one of these sections, not both.
California law recognizes enhanced penalties for drivers with particularly high BAC levels. If your BAC was 0.15% or higher, you may face enhanced penalties including longer license suspensions, extended DUI school requirements, and potentially increased jail time. According to data from the National Highway Traffic Safety Administration[2], drivers with BAC levels of 0.15% or higher are significantly more likely to be involved in fatal crashes.
California Vehicle Code Section 23152(f) and 23152(g) address driving under the influence of drugs, including prescription medications, over-the-counter drugs, and illegal substances. Unlike alcohol DUI, there is no specific numerical threshold for drug impairment, making these cases more complex and often more defensible.
Pomona, located in eastern Los Angeles County with a population of approximately 151,713 according to the U.S. Census Bureau[3], is a vibrant and diverse city that serves as a major commercial and cultural hub for the surrounding region. The city’s location at the intersection of several major freeways, including Interstate 10, State Route 60, and State Route 71, makes it a high-traffic area where DUI enforcement is a priority for local law enforcement.
The Pomona Police Department, along with the California Highway Patrol, conducts regular DUI checkpoints and saturation patrols throughout the city, particularly on weekends, holidays, and during special events at venues like the Fairplex, which hosts the Los Angeles County Fair and numerous other large events throughout the year that attract thousands of visitors.
According to the California Department of Motor Vehicles[4], DUI arrests can result in both criminal penalties through the court system and administrative penalties through the DMV, including driver’s license suspension. Understanding both aspects of a DUI case is crucial for protecting your driving privileges and your freedom.
The penalties for a misdemeanor DUI conviction in California depend on several factors, including whether this is your first offense, your BAC level, whether anyone was injured, and whether there are any aggravating circumstances. California has mandatory minimum penalties for DUI convictions, meaning judges have limited discretion to impose lesser sentences in many cases.
For a first-time DUI offense with no aggravating factors, you face the following potential penalties:
A second DUI offense within ten years carries enhanced penalties:
A third DUI offense within ten years results in even more severe consequences:
In addition to the criminal court case, a DUI arrest triggers an administrative action by the California Department of Motor Vehicles that can result in the suspension of your driver’s license independent of any criminal conviction. Understanding and properly handling the DMV proceedings is crucial for protecting your driving privileges.
When you are arrested for DUI in Pomona, the arresting officer will typically confiscate your physical driver’s license and issue you a pink temporary license that is valid for 30 days. During these 30 days, you have the right to request an Administrative Per Se (APS) hearing to challenge the license suspension.
It is absolutely critical that you request this hearing within 10 days of your arrest. Failure to request a hearing within this timeframe will result in an automatic license suspension after the 30-day temporary license expires. At Tu Defensor Criminalista, we handle the DMV hearing request immediately upon being retained, ensuring that your driving privileges are protected while we fight your case.
The APS hearing is an administrative proceeding separate from your criminal court case. At this hearing, a DMV hearing officer will consider evidence related to:
The burden of proof at a DMV hearing is lower than in criminal court—the DMV only needs to establish facts by a “preponderance of the evidence” rather than “beyond a reasonable doubt.” However, with effective representation, we can challenge the evidence, cross-examine witnesses, and present arguments that may result in the hearing officer setting aside the suspension.
If we win your DMV hearing, your license will not be suspended based on the DUI arrest. If the suspension is upheld, you may still be eligible for a restricted license with an ignition interlock device, allowing you to continue driving to work, school, and DUI classes.
Understanding how DUI arrests typically occur in Pomona can help you recognize potential weaknesses in the prosecution’s case against you. Most DUI arrests in Pomona follow a predictable pattern, and any deviation from proper procedures can provide grounds for challenging the charges.
Most DUI investigations begin with a traffic stop. According to the U.S. Constitution’s Fourth Amendment[6], law enforcement officers must have reasonable suspicion that you have violated a traffic law or reasonable cause to believe criminal activity is occurring before they can legally stop your vehicle.
Common reasons for traffic stops that lead to DUI arrests in Pomona include:
During the initial contact, officers will observe your behavior, speech, and physical appearance looking for signs of intoxication such as bloodshot or watery eyes, slurred speech, odor of alcohol, fumbling with documents, or admission of drinking.
If the officer suspects you are under the influence, they will typically ask you to perform field sobriety tests. It’s important to understand that field sobriety tests are voluntary and you have the right to refuse them without legal penalty. However, many people are unaware of this right and submit to these tests, often to their detriment.
The most commonly administered field sobriety tests in Pomona are the three standardized tests recognized by the National Highway Traffic Safety Administration:
Officers will often ask you to take a preliminary alcohol screening (PAS) test using a portable breathalyzer device at the scene. For drivers over 21, this test is voluntary and you can refuse without penalty (unless you are already on DUI probation). However, officers rarely inform drivers of their right to refuse.
The PAS device is less accurate than the evidential breath testing machines used at the police station, and results can be affected by mouth alcohol, radio frequency interference, improper calibration, and operator error.
If the officer believes they have probable cause that you are under the influence, you will be arrested and taken to the Pomona Police Department or a nearby facility for chemical testing. Under California’s implied consent law (Vehicle Code Section 23612), by driving in California, you have impliedly consented to chemical testing of your breath or blood if lawfully arrested for DUI.
At this point, you must choose between a breath test or a blood test (unless you are incapable of completing a breath test, in which case blood will be required). Both have advantages and disadvantages from a defense perspective:
At Tu Defensor Criminalista, we employ a comprehensive approach to DUI defense, examining every aspect of your case to identify weaknesses in the prosecution’s evidence and develop the strongest possible defense strategy. No two DUI cases are exactly alike, and the most effective defense depends on the unique facts and circumstances of your arrest.
If the officer did not have reasonable suspicion to stop your vehicle, any evidence obtained as a result of the illegal stop may be suppressed and excluded from evidence. We carefully review the officer’s report, dash cam footage, and other evidence to determine whether the stop was justified. If we can demonstrate that the stop violated your Fourth Amendment rights, the entire case may be dismissed.
Field sobriety tests are highly subjective and susceptible to numerous sources of error. We examine:
Many factors unrelated to alcohol intoxication can affect FST performance, and we work to demonstrate that poor performance was not indicative of impairment.
Breath testing devices are complex machines that are subject to various sources of error and interference. We investigate:
While blood testing is generally more accurate than breath testing, blood test results can still be challenged based on:
Your blood alcohol concentration continues to rise for 30 minutes to two hours after you stop drinking. This means your BAC at the time of testing (which can be an hour or more after you were driving) may have been higher than your BAC at the time you were actually driving.
If you had recently consumed alcohol before driving, we may be able to demonstrate that your BAC was below 0.08% while you were driving, even though it measured above that level during testing. This requires expert analysis and calculation based on when you drank, what you drank, your metabolism, and the time elapsed between driving and testing.
In some cases, officers do not actually observe you driving. This can occur when:
If the prosecution cannot prove beyond a reasonable doubt that you were actually driving, they cannot sustain a DUI conviction. We carefully examine the evidence to determine whether the prosecution can establish the driving element.
Various medical conditions can produce symptoms that mimic alcohol intoxication or affect chemical test results:
We thoroughly investigate your medical history and consult with medical experts when appropriate to identify alternative explanations for the observations and test results.
Understanding the criminal court process helps you know what to expect and how to prepare for each stage of your case. Misdemeanor DUI cases in Pomona are prosecuted in the Pomona Branch of the Los Angeles County Superior Court, located at 400 Civic Center Plaza.
Your first court appearance is the arraignment, where you will be formally advised of the charges against you, informed of your constitutional rights, and asked to enter a plea. At Tu Defensor Criminalista, we will appear with you at your arraignment to protect your rights and enter the appropriate plea.
At arraignment, the court will also address bail if you are in custody (most first-time DUI defendants are released on their own recognizance), and set future court dates. We typically enter a not guilty plea at arraignment, which preserves all of your rights and allows us time to investigate your case and review the evidence.
After arraignment, your case enters the pretrial phase, during which several important events occur:
If your case does not resolve through negotiation, you have the right to a jury trial where the prosecution must prove every element of the DUI charges beyond a reasonable doubt. DUI trials typically last one to three days and involve:
Our experienced trial attorneys are not afraid to take cases to trial when it is in your best interest, and we have a proven track record of successful DUI trial outcomes.
If you are convicted or enter a guilty or no contest plea, the court will proceed to sentencing. The judge will consider the circumstances of your offense, your criminal history, mitigating and aggravating factors, and recommendations from both the prosecution and defense before imposing sentence.
At sentencing, we advocate for the most lenient sentence possible, presenting mitigating evidence and arguing for alternatives to jail such as work release, electronic monitoring, or community service.
California law provides some opportunities for alternative sentencing in DUI cases, particularly for first-time offenders. While DUI diversion programs are limited compared to some other offenses, certain options may be available depending on your circumstances.
One of the most common favorable resolutions in DUI cases is a plea to “wet reckless” under Vehicle Code Section 23103.5. This is a reckless driving charge that involves alcohol, and while it is still a priorable offense (meaning it counts as a prior DUI for purposes of future DUI charges), it carries less severe penalties than a DUI conviction:
A wet reckless plea is not available in all cases and typically requires weak prosecution evidence or significant mitigating factors, but it can be an excellent outcome when achievable.
In some cases with particularly weak evidence, we may be able to negotiate a plea to “dry reckless” under Vehicle Code Section 23103, which is reckless driving without the alcohol allegation. This is not a priorable offense, carries even less severe penalties, and has minimal impact on insurance rates.
For clients who must serve jail time, Los Angeles County offers various alternative custody programs that may allow you to serve your sentence through:
These alternatives allow you to maintain employment and family obligations while completing your sentence.
Beyond the immediate criminal penalties, a DUI conviction can have far-reaching consequences that affect many aspects of your life. Understanding these collateral consequences underscores the importance of fighting your charges with an experienced attorney.
A DUI conviction creates a permanent criminal record that can affect employment in numerous ways:
A DUI conviction will result in dramatically increased auto insurance rates or potential policy cancellation. California law requires DUI offenders to file an SR-22 certificate, which is proof of financial responsibility insurance. According to the California Department of Insurance[9], DUI convictions typically result in insurance rate increases of 50% to 200% or more, lasting for several years.
For non-U.S. citizens, a DUI conviction can have serious immigration consequences. While a simple first-time misdemeanor DUI is generally not considered a deportable offense or crime involving moral turpitude, multiple DUI convictions or DUI convictions involving aggravating factors can affect your immigration status.
According to U.S. Citizenship and Immigration Services[10], any criminal conviction can potentially affect naturalization applications, green card renewals, or visa applications. It is crucial to consult with an immigration attorney in addition to your DUI attorney if you are not a U.S. citizen.
Given that approximately 40.8% of Pomona’s population is foreign-born according to the U.S. Census Bureau[3], these immigration considerations are particularly relevant to many members of our community.
Students convicted of DUI may face consequences from their educational institutions, including:
The social stigma of a DUI conviction can strain personal relationships, damage your reputation in the community, and create stress and embarrassment that affects your mental health and quality of life.

Understanding Pomona’s unique characteristics helps contextualize DUI enforcement in the city and identify opportunities for effective defense.
Pomona is a diverse city with a rich history, serving as a major commercial and cultural center for the eastern San Gabriel Valley and Pomona Valley regions. According to the U.S. Census Bureau[3], approximately 71.3% of Pomona’s population is Hispanic or Latino, making it one of the most diverse cities in Los Angeles County.
DUI enforcement in Pomona focuses on several key areas:
The Pomona Police Department regularly conducts DUI checkpoints, also known as sobriety checkpoints, particularly during holiday periods and special events. While DUI checkpoints are legal in California (unlike some other states), they must be conducted according to strict constitutional guidelines.
Checkpoints must be:
If you were arrested at a DUI checkpoint that did not comply with these requirements, we may be able to challenge the legality of the checkpoint and have evidence suppressed.
After a DUI arrest, your immediate priorities should be to request a DMV hearing within 10 days to protect your license, refrain from discussing your case with anyone except your attorney and contact an experienced DUI defense lawyer as soon as possible. At Tu Defensor Criminalista, we can guide you through every step and begin building your defense immediately.
Yes, if you are over 21 and not on DUI probation, field sobriety tests and the preliminary alcohol screening (PAS) roadside breath test are voluntary, and you can refuse them without penalty. However, once you are arrested, you must submit to chemical testing (breath or blood) or face enhanced penalties for refusal.
For a first-time DUI, the DMV would suspend your license for six months if you took a chemical test, or one year if you refused testing. However, you may be eligible for a restricted license with an ignition interlock device that allows you to drive to work, school, and DUI classes.
Yes, DUI cases can be dismissed when there are constitutional violations, insufficient evidence, errors in testing procedures, or other legal defenses. Every case is different, and we thoroughly investigate all aspects of your case to identify grounds for dismissal.
An ignition interlock device (IID) is a breath testing device connected to your vehicle’s ignition that requires you to provide a breath sample before the car will start. If alcohol is detected, the vehicle will not start. All California DUI offenders are now required to install an IID.
While a first-time DUI carries up to six months in county jail, many first-time offenders receive probation without actual jail time, particularly when represented by an experienced attorney. However, circumstances such as high BAC, accidents, or other aggravating factors can increase the likelihood of custody time.
The total cost of a DUI conviction includes fines and penalty assessments ($2,000+), DUI school ($500-$1,800), license reissuance fees, increased insurance premiums (thousands of dollars over several years), ignition interlock device costs ($70-$150/month), and attorney fees. The total cost can easily exceed $10,000 to $15,000.
Yes, a DUI conviction can affect employment through background checks, professional license issues, inability to drive to work during suspension, and potential termination depending on your employment contract and company policies. Certain professions are particularly affected, including commercial drivers, healthcare professionals, and teachers.
The DMV Administrative Per Se (APS) hearing is a separate proceeding from your criminal case where a hearing officer determines whether your license should be suspended based on the DUI arrest. We represent you at this hearing, cross-examine witnesses, present evidence, and argue for reinstatement of your license.
A DUI conviction remains on your criminal record permanently unless you obtain an expungement under Penal Code Section 1203.4. A DUI also remains on your DMV driving record for 10 years for purposes of counting as a prior offense if you receive another DUI.
If you have been arrested for DUI in Pomona or anywhere in Los Angeles County, do not face the criminal justice system alone. The consequences of a DUI conviction are too severe to risk inadequate representation, and the sooner you engage an experienced DUI defense attorney, the better we can protect your rights and fight for the best possible outcome.
