A DUI conviction can have a significant impact on your life. Some of the consequences of DUIs include fines, jail time, and driver’s license suspension. It could even affect your ability to maintain or obtain certain types of employment. Is it worth it to fight your charges?
A DUI arrest does not automatically mean a conviction, and early action can be important to protecting your driving privileges and building your defense. Lias Law Firm can review the circumstances of your arrest, explain your options, and help you address urgent deadlines.

What Are the Blood Alcohol Concentration (BAC) Limits in California?
For most adult noncommercial drivers, California’s per se DUI limit is a BAC of 0.08% or higher. A person may also face DUI charges based on alleged impairment from alcohol, drugs, or a combination of substances, even with a BAC below 0.08%.
Drivers under 21 and drivers on DUI probation may face DMV consequences for a BAC of 0.01% or higher. Commercial drivers operating commercial vehicles may face DUI-related consequences at 0.04% or higher. Drivers transporting passengers for hire may also be subject to lower BAC limits and additional licensing consequences.
The charges and penalties in any DUI case depend on the specific facts, the driver’s status, and the evidence involved.
What Happens if I Refuse a DUI Breathalyzer Test?
Whether you may decline a test depends on the type of test and the stage of the DUI investigation. After a lawful DUI arrest, California’s implied consent law generally requires drivers to submit to a chemical test. Refusal can lead to separate DMV consequences and may affect the criminal case. This law aims to ensure the safety of all road users by discouraging impaired driving.
If the DMV sustains a chemical test refusal allegation, potential consequences can include a one-year suspension for a first alleged refusal, a two-year revocation for a qualifying second offense within 10 years, and a three-year revocation for a qualifying third offense within 10 years. The applicable consequence depends on the allegation, prior history, and DMV findings.
In some cases, the prosecution may argue that an alleged refusal supports an inference of consciousness of guilt. The facts surrounding the advisement, arrest, test request, and alleged refusal may all be important to the defense.
Drug, Marijuana, and Prescription DUI Charges
Unlike an alcohol based per se DUI allegation, a drug DUI case does not depend on a specific BAC threshold. Prosecutors generally must instead attempt to prove that a drug, medication, or combination of substances impaired the person’s ability to drive safely.
Drug DUI allegations can involve substances such as:
- Marijuana, including THC impairment allegations
- Prescription pain medication, sedatives, sleep aids, or anti-anxiety medications
- Over-the-counter medication that causes drowsiness or otherwise affects driving
- Illegal drugs, including stimulants or narcotics
- Alcohol combined with prescription, over the counter, or recreational drugs
Defending a drug DUI often requires close review of the officer’s observations, driving pattern, field sobriety testing, chemical test procedures, timelines, medical history, and the evidence relied on to claim impairment. An experienced Santa Clarita DUI attorney can identify whether the prosecution has reliable evidence connecting a substance to alleged impaired driving.
Underage and Zero-Tolerance DUI in California
California’s zero tolerance law exposes drivers under 21 to license consequences at a much lower alcohol level than the standard adult DUI limit. A driver under 21 may face an administrative suspension for a BAC of 0.01% or higher or for refusing a required test.
This is different from the standard adult per se DUI BAC limit of 0.08%. An underage driver can therefore face DMV consequences even when the BAC is far below 0.08% and even when the facts may not support a traditional adult DUI charge.
An underage DUI case may involve multiple issues at once, including:
- A zero-tolerance DMV action based on a BAC of 0.01% or higher
- A criminal DUI allegation, if the state claims alcohol or drugs impaired driving
- Allegations involving possession of alcohol in a vehicle
- A chemical-test refusal allegation
- Consequences for a young driver’s license, education, employment, and future opportunities
Because DMV deadlines may apply soon after an underage alcohol-related stop or arrest, a parent or young driver should seek legal advice promptly rather than waiting for a court date.
California DUI Penalties: What to Expect After a DUI Arrest
A DUI arrest or conviction can trigger separate consequences through the DMV and criminal court. The DMV may pursue an administrative suspension or revocation, while a court may impose criminal penalties and driving-related conditions as part of a sentence. The outcome can depend on the charge, alleged BAC, prior history, refusal allegations, and other facts.
Penalties for a First-Offense DUI in California
A first-offense DUI conviction can carry significant consequences, which may include:
- A base fine of $390 to $1,000, plus penalty assessments and other fees
- Possible county jail time
- Probation and court-ordered conditions
- A DMV suspension, revocation, or restricted-driving requirement
- Enrollment in a state-licensed DUI education program
- Possible ignition interlock device requirements
These penalties are designed to deter impaired driving and emphasize the state’s strict stance on road safety. If you’re facing first-offense DUI charges, it’s critical to understand your rights and explore your legal options with the help of an experienced DUI attorney.
Aggravated DUI Penalties for Repeat Offenders
Facing multiple DUI charges or a DUI involving aggravating circumstances, such as causing injury, can lead to significantly harsher penalties in California. The penalties increase for subsequent DUI offenses or cases involving aggravating factors like injuries.
A second or third DUI within 10 years can result in increased jail exposure, longer probation, higher financial penalties, longer DUI education requirements, and more serious DMV consequences. Depending on the case, the DMV may impose a suspension, revocation, or IID-related restriction, and the court may impose additional driving-related conditions.
A DUI causing injury may be charged as a misdemeanor or felony, depending on the circumstances and alleged injuries. A felony DUI injury conviction can carry substantial fines, prison exposure, restitution obligations, DMV consequences, and other penalties. The potential sentence depends on factors such as prior convictions, the number and severity of injuries, and any sentencing enhancements alleged by the prosecution.
These penalties reflect the state’s firm stance on repeat and aggravated DUI offenses. To protect your rights and work toward the best possible outcome, it’s essential to consult a knowledgeable DUI attorney who can build a strong defense on your behalf.
Long-Term Consequences of a DUI Conviction
DUI convictions are placed on a person’s driving record and criminal record. Previous convictions are taken into consideration when determining the specific penalties, including the length of both the prison sentence and driver’s license suspension, as well as the amount of the fine.
To start fighting your possible penalties, get in contact with our DUI lawyer in Santa Clarita as soon as possible.
Ignition Interlock Devices and DUI School Requirements
A DUI conviction or DMV action may affect when and how you can drive. Possible requirements include an ignition interlock device, or IID, and a DUI education program.
An IID is a breath-testing device installed in a vehicle that requires a breath sample before the vehicle will start. California law may require an IID after certain DUI convictions, particularly repeat or injury-related offenses. A first-time DUI may also involve a court-ordered IID or IID-restricted driving option, depending on the case and DMV eligibility.
DUI education may be required as part of a court sentence or to obtain or restore restricted driving privileges. Requirements vary based on the charge, prior history, court orders, and DMV action. A wet reckless resolution can also carry court-ordered conditions. Lias Law Firm can explain the requirements that may apply to your situation and help you evaluate your options.
Defenses Against DUI Charges in California
Facing a DUI charge in California can be overwhelming, but it’s important to remember that being charged is not the same as being convicted. Strong legal defense strategies can highlight errors, inconsistencies, or mitigating factors that could lead to reduced charges or even dismissal. Understanding your rights and the available defenses is a vital step toward protecting your future.
What Percentage of DUI Cases Are Dismissed in California?
California DMV data shows that not every DUI arrest results in a recorded DUI conviction. In the DMV’s 2025 reporting data, 66.6% of DUI arrests resulted in a DUI conviction, while 23.6% did not result in a recorded conviction. That latter category can include dismissals, reductions to non-DUI offenses, acquittals, and cases involving a failure to appear, so it should not be treated as a pure dismissal rate.
Every DUI case turns on its own facts. The outcome may depend on the legality of the traffic stop, the basis for the arrest, officer observations, field sobriety testing, chemical-test procedures, video footage, and whether the prosecution can prove the charge beyond a reasonable doubt.
A DUI arrest does not automatically mean a conviction, but no attorney can guarantee that charges will be dismissed or reduced. Lias Law Firm can evaluate the evidence, explain the available options, and build a defense strategy based on the circumstances of your case. Call (661) 592-9001 to schedule a free consultation with a Santa Clarita DUI lawyer.
Challenging BAC Test Results in Court
BAC is a critical piece of evidence in most DUI cases. However, BAC test results are not always as reliable as they appear. Several factors can challenge the validity of these results, and an experienced DUI lawyer can explore these avenues to build your defense. Factors may include:
- Improper Calibration or Maintenance of Testing Equipment: If calibration, maintenance, or recordkeeping issues exist, they may affect the reliability or admissibility of the test result and may provide grounds for further investigation or challenge.
- Errors in Administering the Test: The accuracy of chemical tests depends on proper administration. Inexperienced or improperly trained officers can make errors such as failing to follow the required observation period, using improper procedures or supplies, or not following applicable testing protocols.
- Rising Blood Alcohol Levels: Alcohol absorption can continue after a person stops drinking, and BAC may rise between the time of driving and the time of a later chemical test. Whether this is relevant depends on the drinking timeline, test timing, and available evidence.
- Health Conditions or Medications: Certain medical conditions, physiological factors, and medications may be relevant to the reliability of a breath-test result. Any potential issue should be evaluated based on the person’s medical information, the testing device used, the procedures followed, and the available records.
By examining these potential issues, your attorney can challenge the reliability of BAC evidence, which is often the backbone of the prosecution’s case.
Defending Against Police Misconduct and Errors
When officers fail to follow applicable legal or testing procedures, the error may affect the reliability, admissibility, or weight of the prosecution’s evidence. The impact depends on the specific facts and the evidence available. Attorney Antionette Lias can examine whether the officer had a lawful basis for the stop, whether field sobriety tests were administered properly, and whether available body-camera or dash-camera footage supports the police report.
A DUI case may involve overlapping DMV and court proceedings, technical evidence, and strict deadlines. A defense lawyer can evaluate the record, identify potential issues, and advise you about the options available in your case.
Can a DUI Be Reduced to Wet Reckless?
In some California DUI cases, a prosecutor may agree to reduce a DUI charge to reckless driving involving alcohol or drugs, commonly called a wet reckless. A wet reckless is generally a negotiated resolution to a DUI case rather than the original charge filed after an arrest. Instead, it can be a negotiated resolution to a DUI case under California Vehicle Code sections 23103 and 23103.5.
A wet reckless may carry different consequences than a DUI conviction, but it is not a guaranteed outcome and may not be appropriate or available in every case. Whether a reduction is possible can depend on the evidence, alleged BAC level, prior record, legal issues with the stop or testing, and other facts of the case.
A wet reckless resolution in criminal court does not automatically resolve a separate DMV APS matter. The criminal case and DMV proceedings must be evaluated independently.
Lias Law Firm can review the evidence in your case and explain whether dismissal, a charge reduction, or another defense strategy may be available. Call (661) 592-9001 to discuss your DUI case with a Santa Clarita criminal defense lawyer.
Understanding Field Sobriety Tests in DUI Cases
Field sobriety tests are designed to help officers determine whether a driver is under the influence of alcohol or drugs. These tests measure physical coordination, attention, and the ability to follow instructions. All of these are skills that can be impaired by intoxication.
However, it’s important to note that field sobriety tests are not always accurate indicators of impairment. Many factors, such as medical conditions, age, nervousness, or even poor instructions from the officer, can impact how someone performs.
What Are the Three Field Sobriety Tests?
The National Highway Traffic Safety Administration identifies three standardized field sobriety tests that law enforcement officers commonly use during DUI investigations:
- Horizontal Gaze Nystagmus (HGN) Test: This tracks involuntary eye movements for signs of impairment.
- Walk-and-Turn Test: This measures coordination, balance, and the ability to follow multi-step instructions.
- One-Leg Stand Test: This evaluates balance and attention by asking the driver to stand on one leg for an extended period of time.
Officers may use these tests, along with driving observations, statements, and other evidence, when deciding whether they believe further DUI investigation or an arrest is warranted. Performance can be affected by factors unrelated to alcohol or drug impairment, including medical conditions, age, injuries, footwear, roadway conditions, instructions, and nervousness.
How Field Sobriety Tests Impact Your DUI Defense
Field sobriety tests are an integral part of a DUI investigation, often serving as one of the first tools law enforcement officers use to assess whether a driver may be impaired. While these tests are widely used, understanding how they work, and their limitations, can be crucial if you are facing DUI charges. Although field sobriety tests are a common tool in DUI cases, they are not foolproof. The results of these tests are often subjective and open to interpretation.
What Happens After a DUI Arrest in California?
A DUI arrest can start two separate processes at once: a DMV administrative case involving your driving privileges and a criminal case in court. While every situation is different, the process commonly follows these steps:
- You receive DMV suspension paperwork. After an arrest, the officer may take your physical driver’s license and issue an Order of Suspension or Revocation and a temporary license. This notice starts the DMV’s Administrative Per Se, or APS, process.
- You have 10 days to request a DMV hearing. You must request an APS hearing within 10 days of receiving the suspension or revocation order if you want to challenge the DMV’s action. This deadline is separate from your court date.
- The DMV addresses your driving privilege. At an APS hearing, the DMV considers whether it has a legal basis to suspend or revoke your license. The hearing does not decide whether you are guilty of a DUI crime. If you do not make a timely hearing request, the DMV action may proceed without a hearing.
- The criminal case begins in court. If prosecutors file charges, your first court appearance is typically an arraignment. At that hearing, the court advises you of the charges and your rights, and a plea is entered.
- Your case moves through review, negotiation, motions, or trial. A DUI defense attorney can review police reports, chemical-test records, video footage, and other evidence; identify possible issues with the stop or arrest; and pursue the most appropriate defense strategy for your circumstances.
The DMV proceeding and criminal court case can move forward on separate tracks. A license suspension issue may require immediate attention, even before your first criminal court date.

Requesting a DMV Hearing After a DUI Arrest: The 10-Day Deadline
After a DUI arrest in California, you may face two separate proceedings: a criminal case in court and an Administrative Per Se, or APS, action through the California Department of Motor Vehicles. The DMV process concerns your driving privilege, while the criminal case determines whether you face a DUI conviction and criminal penalties.
The arresting officer may take your physical driver’s license and provide an Order of Suspension or Revocation along with a temporary license. This notice generally allows you to drive temporarily, but you have only 10 days from receiving the notice to request a DMV hearing. The DMV does not automatically schedule this hearing for you.
If you miss the deadline, the DMV can move forward with an APS suspension or revocation without a hearing. Do not wait for your first court date to address the DMV action. The DMV case can proceed even while the criminal DUI charge is pending.
What Is an APS Hearing?
An APS hearing is an administrative proceeding before the DMV, not a criminal trial. The hearing officer considers whether the DMV has a legal basis to suspend or revoke your driving privilege after the arrest.
Depending on the allegations, the issues may include:
- Whether the officer had reasonable cause to believe you were driving under the influence
- Whether you were lawfully arrested
- Whether you were driving with a BAC at or above the applicable legal limit
- In a chemical-test-refusal case, whether you were properly advised of the consequences and refused or failed to complete the required test
The DMV can set aside its action if it determines there is no legal basis for the suspension or revocation.
The DMV Case Is Separate From the Criminal Case
A DMV APS hearing and a DUI case in Los Angeles County criminal court are related, but they are separate matters with different purposes and procedures. The DMV can take action against your license even if you have not yet been convicted in court. Similarly, a favorable DMV outcome does not automatically end the criminal case.
Because the early evidence can affect both proceedings, it is important to act quickly. A Santa Clarita DUI lawyer can request the DMV hearing, seek a stay of the suspension while the matter is pending when appropriate, review the evidence, and assess potential challenges to the arrest, chemical test, or DMV action.

DUI FAQs
What is the 10-day rule for a DUI in California?
After receiving an Order of Suspension or Revocation following a DUI arrest, you generally have 10 days to request a DMV APS hearing. This administrative matter is separate from the criminal DUI case and can affect your driving privilege even while the court case is pending.
Can I get a DUI reduced to a wet reckless?
Possibly. In some cases, a DUI charge may be resolved as a reckless-driving offense involving alcohol or drugs, often called a wet reckless. This is generally a negotiated reduction under California Vehicle Code sections 23103 and 23103.5, not an automatic right or guaranteed outcome.
How long does a DUI stay on your record in California?
A California DUI conviction generally remains on a DMV driving record for 10 years. During that period, it can be considered when evaluating the consequences of a later DUI or DUI-related conviction. A DUI can remain on a criminal record longer than it remains on the DMV driving record.
Can I expunge a DUI from my record?
In some cases, a person who has completed probation and satisfied other requirements may be eligible to seek a post-conviction dismissal, often called an expungement. A dismissal can provide important relief, but it does not erase the case from every record, remove DMV history, or eliminate all collateral consequences. Eligibility depends on the conviction, sentence, probation status, and other circumstances.
Will my auto insurance rates go up after a DUI?
A DUI conviction can lead to higher auto insurance premiums, policy cancellation or nonrenewal, and additional proof-of-insurance requirements. The effect depends on the insurer, driving history, coverage, and other circumstances.
How much does a DUI cost in California?
The financial impact of a DUI can extend well beyond the base fine. Depending on the case, expenses may include penalty assessments, towing and impound costs, DUI school, IID costs, DMV fees, increased insurance premiums, and lost income or transportation expenses.
Do I have to appear in court for a DUI in Santa Clarita?
In some misdemeanor DUI cases, California Penal Code section 977 may allow an attorney to appear for a client at certain hearings. A judge can require a personal appearance, and a defendant will usually need to appear for proceedings such as trial, sentencing, or any hearing where the court orders attendance. Felony DUI cases may have different appearance requirements.
