In California, driving under the influence is governed primarily by Vehicle Code Section 23152[1], which makes it unlawful 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[2], thousands of DUI arrests occur throughout Los Angeles County each year, with a significant portion involving first-time offenders who never imagined they would face criminal charges.
Pomona, a diverse city of approximately 151,713 residents located in eastern Los Angeles County according to the U.S. Census Bureau[3], serves as a major hub for the surrounding communities. The city’s location at the convergence of multiple major freeways—including Interstate 10, State Route 60, and State Route 71—combined with its vibrant downtown entertainment district and the presence of the Fairplex (home to the L.A. County Fair and numerous events), creates numerous opportunities for DUI enforcement by both the Pomona Police Department and the California Highway Patrol.
In California, you are considered a first-time DUI offender if you have no prior DUI convictions within the past 10 years. This 10-year “lookback period” is significant because it determines which penalties apply to your case. Even if you had a DUI arrest or conviction more than 10 years ago, you will typically be treated as a first-time offender for sentencing purposes.
It’s important to understand that prior DUI arrests that did not result in convictions generally do not count against you. Only actual convictions within the 10-year lookback period will enhance your penalties. This is one reason why fighting your first DUI charge is so important—a conviction will follow you for at least 10 years and will result in enhanced penalties if you are ever arrested for DUI again.
Most first-time DUI arrests in Pomona result in charges under two separate code sections:
Most DUI arrests result in being charged with both violations, though you can only be punished under one count. This dual-charging strategy gives prosecutors two different paths to conviction, but it also gives experienced defense attorneys like those at Tu Defensor Criminalista more opportunities to identify weaknesses in the prosecution’s case.
California has mandatory minimum penalties for DUI convictions, even for first-time offenders. However, the actual penalties you face can vary significantly depending on the specific facts of your case, your BAC level, whether there was an accident, and how effectively your attorney negotiates on your behalf.
For a standard first-time DUI with no aggravating factors, you face:
Certain circumstances can result in enhanced penalties even for first-time offenders:
When you are arrested for DUI in Pomona, the arresting officer will confiscate your physical driver’s license and issue you a pink temporary license valid for 30 days. What many first-time offenders don’t realize is that you have only 10 days from the date of your arrest to request a hearing with the California Department of Motor Vehicles to contest the automatic license suspension.
This DMV Administrative Per Se (APS) hearing is separate from your criminal court case and has its own deadlines and procedures. If you fail to request a hearing within 10 days, your license will automatically be suspended when your temporary license expires, and you will lose your opportunity to challenge the suspension.
This is one of the most critical reasons to contact an experienced DUI attorney immediately after your arrest. At Tu Defensor Criminalista, we handle the DMV hearing request as soon as we are retained, ensuring that your driving privileges are protected while we fight your case. According to the California Department of Motor Vehicles[5], the administrative license suspension can often be successfully challenged at a DMV hearing with proper legal representation.
The APS hearing is an administrative proceeding where a DMV hearing officer determines whether your license should be suspended based on your DUI arrest. The hearing officer will consider:
The hearing can be conducted in person or by telephone, and having an experienced attorney represent you can make a significant difference. We can subpoena the arresting officer to testify, cross-examine witnesses, challenge the reliability of chemical tests, and present evidence supporting your case.
If we win your DMV hearing, your license will not be suspended based on the DUI arrest. Even if the hearing officer upholds the suspension, we can often help you obtain a restricted license with an IID, allowing you to continue driving to work, school, and DUI classes during the suspension period.
Understanding how DUI arrests typically occur can help you recognize potential weaknesses in the prosecution’s case. Most DUI arrests in Pomona follow a predictable pattern, and any deviation from proper procedures can provide grounds for challenging the charges.
Most DUI cases begin with a traffic stop. Under the Fourth Amendment to the U.S. Constitution[6], police 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:
However, not all traffic stops are legal. If the officer did not have valid reasonable suspicion or probable cause to stop you, any evidence obtained as a result of the illegal stop may be suppressed, potentially leading to dismissal of your charges.
Once the officer suspects you may be under the influence (typically based on observations like bloodshot eyes, slurred speech, or odor of alcohol), they will usually ask you to perform field sobriety tests (FSTs).
It is crucial to understand that field sobriety tests are voluntary in California. If you are over 21 and not on DUI probation, you have the legal right to politely refuse to perform these tests without penalty. Many people don’t know this and submit to tests that can be extremely difficult to pass even when completely sober.
The three standardized field sobriety tests commonly used by Pomona police officers are:
These tests are highly subjective and can be affected by numerous factors unrelated to alcohol, including:
Even completely sober individuals often have difficulty performing these tests perfectly, especially under the stress of a police encounter. An experienced DUI attorney can challenge the reliability and administration of field sobriety tests.
Officers typically also ask drivers to take a preliminary alcohol screening test using a handheld breathalyzer device at the roadside. Like field sobriety tests, the PAS test is voluntary for drivers over 21 who are not on DUI probation. You can refuse this test without penalty.
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 other factors. Refusing the PAS test deprives the officer of additional evidence that could be used against you.
If the officer believes they have probable cause that you are under the influence, you will be arrested and transported to the Pomona Police Department or another facility for chemical testing. At this point, California’s “implied consent” law under Vehicle Code Section 23612[1] applies.
By driving in California, you have impliedly consented to submit to chemical testing of your breath or blood if lawfully arrested for DUI. After arrest, refusing chemical testing results in mandatory enhanced penalties, including a one-year license suspension with no restricted license option for a first offense.
You will be given a choice between a breath test or a blood test (unless you are unable to complete a breath test, in which case blood will be required). Each has advantages and disadvantages from a legal standpoint:
At Tu Defensor Criminalista, we employ a comprehensive, multi-faceted approach to defending first-time DUI charges. We understand that every case is unique, and we carefully analyze all aspects of your arrest to identify weaknesses in the prosecution’s case and develop the strongest possible defense.
The Fourth Amendment protects you against unreasonable searches and seizures. If the police officer did not have valid reasonable suspicion to stop your vehicle, we can file a motion to suppress all evidence obtained as a result of the illegal stop. Without the evidence from the stop, the prosecution’s case typically collapses.
We thoroughly review:
Even minor inconsistencies between the officer’s testimony and the video evidence can be grounds for challenging the stop.
Field sobriety tests are notoriously unreliable and subjective. We examine:
Many factors completely unrelated to alcohol consumption can affect FST performance, and we work to demonstrate that poor performance does not necessarily indicate impairment.
Both breath and blood testing are complex scientific procedures susceptible to error. We investigate:
For Breath Tests:
For Blood Tests:
According to the National Highway Traffic Safety Administration[7], proper procedures must be followed for chemical test results to be reliable and admissible in court.
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 significantly higher than your BAC at the time you were actually operating the vehicle.
If you consumed alcohol shortly before driving, we may be able to demonstrate through expert testimony that your BAC was below the legal limit while you were driving, even though it measured above 0.08% during later testing.
In some cases, particularly those involving parked vehicles or accidents where no one witnessed you driving, the prosecution may have difficulty proving that you were actually driving. If they cannot prove beyond a reasonable doubt that you were driving, they cannot sustain a DUI conviction.
Various medical conditions can mimic signs of intoxication or affect chemical test results:
We thoroughly investigate your medical history and consult with medical experts when appropriate.
Understanding what to expect during the court process can help reduce anxiety and allow you to prepare effectively. First-time DUI cases in Pomona are handled at the Pomona Courthouse, located at 400 Civic Center Plaza, Pomona, CA 91766.
Your first court appearance is the arraignment, typically scheduled within a few weeks of your arrest. At the arraignment:
At Tu Defensor Criminalista, we appear with you at your arraignment to protect your rights. We typically enter a not guilty plea, which preserves all of your rights and options while we investigate your case and negotiate with prosecutors.
After arraignment, your case enters the pretrial phase, which typically includes:
First-time DUI cases can be resolved in several ways:
Beyond the immediate criminal penalties, a first-time DUI conviction can have lasting effects on many aspects of your life. Understanding these consequences underscores the importance of fighting your charges with experienced legal representation.
A DUI conviction creates a permanent criminal record that will appear on background checks. According to the U.S. Bureau of Labor Statistics[8], most employers conduct criminal background checks, and a DUI conviction can affect:
For first-time offenders who successfully complete probation, California allows for petition for expungement under Penal Code Section 1203.4, which can minimize the long-term employment impact.
A DUI conviction will result in dramatically increased insurance rates or policy cancellation. The California Department of Insurance[9] requires DUI offenders to file an SR-22 certificate proving financial responsibility. Insurance rate increases of 50% to 200% or more are common and typically last for several years.
If you hold a commercial driver’s license, even a first-time DUI in your personal vehicle will result in a one-year CDL suspension. According to the Federal Motor Carrier Safety Administration[10], this can effectively end your career as a commercial driver.
For non-U.S. citizens, even a first-time misdemeanor DUI can potentially affect immigration status, naturalization applications, or visa renewals. According to U.S. Citizenship and Immigration Services[11], any criminal conviction should be evaluated by an immigration attorney.
Given that approximately 40.8% of Pomona’s population is foreign-born according to the U.S. Census Bureau[3], immigration consequences are particularly relevant to many members of our community.
Students may face disciplinary action from their school, loss of scholarships or financial aid, and damage to graduate school applications as a result of a DUI conviction.
Many first-time DUI defendants make the critical mistake of assuming they should simply plead guilty and accept whatever punishment the court imposes. This is almost never the right approach. Here’s why:
Pomona’s unique characteristics create specific contexts for DUI arrests and prosecution that first-time offenders should understand.
Pomona is one of the most diverse cities in California, with approximately 71.3% of the population identifying as Hispanic or Latino according to the U.S. Census Bureau[3]. This diversity means that language barriers, cultural differences, and immigration concerns may play important roles in DUI cases.
At Tu Defensor Criminalista, we offer fully bilingual services in English and Spanish, ensuring that language is never a barrier to understanding your rights and options.
DUI enforcement in Pomona focuses on several key areas:
The Pomona Courthouse handles DUI cases for much of eastern Los Angeles County. The prosecutors and judges at this courthouse have their own tendencies and practices, and experience with the local court system is invaluable for effective representation.
Our attorneys regularly appear in the Pomona courthouse and have developed working relationships with local prosecutors and familiarity with local judges, which benefits our clients through more effective negotiations and advocacy.

While a first-time DUI carries a maximum of six months in county jail, many first-time offenders avoid jail entirely through effective legal representation, particularly when there are no aggravating factors like high BAC, accidents, or injuries. Even when jail time is imposed, it can often be served through alternative programs like work release or electronic monitoring.
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 after a 30-day hard suspension period.
Yes, first-time DUI charges can be dismissed when there are constitutional violations, insufficient evidence, errors in testing procedures, or other valid legal defenses. Every case is different, and we thoroughly investigate all aspects of your arrest to identify grounds for dismissal.
A “wet reckless” is a reckless driving charge that involves alcohol (Vehicle Code Section 23103.5). It is a common negotiated resolution in DUI cases and carries less severe penalties than a DUI conviction, including no mandatory jail time, shorter DUI classes, and less impact on insurance rates.
Field sobriety tests are voluntary for drivers over 21 who are not on DUI probation, and you can politely decline without penalty. These tests are difficult to pass even when sober and are often used as evidence against you. However, this is a personal decision that depends on your specific circumstances.
After a DUI arrest, you should: (1) Request a DMV hearing within 10 days to protect your license, (2) Do not discuss your case with anyone except your attorney, (3) Contact an experienced DUI defense attorney as soon as possible, (4) Write down everything you remember about the arrest while details are fresh, (5) Preserve any evidence that might help your case, such as receipts showing when and what you drank.
The total cost of a first-time DUI conviction can easily exceed $10,000-$15,000 when considering 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 for six months), and attorney fees.
While you have the right to represent yourself, it is rarely advisable. DUI law is complex, the consequences are severe, and prosecutors are experienced attorneys. Without legal representation, you may miss valid defenses, make damaging statements, or accept unfavorable plea agreements.
A DUI can affect employment through background checks, professional license issues, inability to drive to work during license suspension, and potential termination depending on your employer’s policies. The impact varies by industry and position, but having an attorney fight to avoid a conviction or minimize penalties is crucial for protecting your career.
If you successfully complete probation for a first-time DUI, you may be eligible to petition for expungement under California Penal Code Section 1203.4. An expungement sets aside the conviction and dismisses the case, though certain restrictions still apply.
If you have been arrested for your first DUI in Pomona, time is critical. You have only 10 days from your arrest to request a DMV hearing, and the sooner you engage experienced legal counsel, the better we can protect your rights and build your defense.
