What is Considered a DUI in California?

Driving Under the Influence (DUI) in California refers to the act of operating a motor vehicle while intoxicated from alcohol, drugs, or a combination of both, to the extent that it impairs your ability to drive safely. The key factors that constitute a DUI in California are the blood alcohol concentration (BAC) and the type of substance involved.

The following are common types of DUI in California:

  • Alcohol DUI: In California, the legal limit for alcohol is typically 0.08% BAC for individuals over the age of 21. If you are caught driving with a BAC at or above this limit, you can be charged with a DUI.
  • Underage DUI: For drivers under the age of 21, California has a "zero-tolerance" policy. This means that any measurable amount of alcohol in their system while driving is illegal and can lead to a DUI.
  • Drug DUI: Apart from alcohol, driving under the influence of drugs, whether illegal substances or prescription medications that impair your ability to drive safely, can also result in a DUI charge.
  • Combination of Alcohol and Drugs: Driving under the influence of both alcohol and drugs, even if they are within legal limits individually, can also lead to a DUI arrest if the combination impairs your driving ability.

DUI Cases We Handle

We handle all types of DUI charges, including the following:

Is a DUI a Felony or Misdemeanor in California?

In California, a DUI is generally a misdemeanor. However, if the offense meets any of the following conditions, the charge could be enhanced to a felony:

  • If an individual other than the driver was injured or killed as a direct result of the DUI offense
  • If it is the fourth or subsequent DUI charge within 10 years
  • If there are prior felony convictions for any kind of vehicle code violations
  • If there was an underaged individual present in the vehicle during the arrest

What is Wet Reckless Driving in California?

"Wet reckless" is a term used in California to refer to a specific type of plea bargain that can be negotiated for certain DUI offenses. It is a lesser charge than a standard DUI and typically involves reckless driving that is alcohol-related.

In a wet reckless plea bargain, the charge of driving under the influence (DUI) is reduced to reckless driving with alcohol involved. This can have potential advantages for the defendant, as wet reckless offenses generally carry lighter penalties than standard DUI offenses. Penalties for wet reckless driving might include fines, probation, mandatory alcohol education programs, and possibly shorter license suspensions compared to those associated with a full DUI conviction.

It's important to note that not all DUI cases are eligible for a wet reckless plea bargain. The decision to offer a wet reckless plea deal depends on various factors, including the specific circumstances of the case, the defendant's prior criminal record, the blood alcohol content (BAC) at the time of the arrest, and other relevant details.

What Are My Rights During an Arrest?

Understanding your rights during a DUI arrest is critical. Exercising these rights properly can significantly impact the outcome of your case. You have the following essential protections:

  • The Right to Remain Silent: You are not mandated to answer questions about where you were coming from, whether you have been drinking, or any other potentially incriminating details. You can politely refuse to answer questions by stating, "I choose to remain silent."
  • The Right to Refuse Field Sobriety Tests: In California, you are not legally required to perform field sobriety tests during a DUI stop. These tests are voluntary, and refusing them cannot be used against you in court.
  • The Right Against Unlawful Searches and Seizures: Law enforcement officers must follow strict guidelines when searching your vehicle or person. They cannot search your property without your consent, a warrant, or a valid legal exception.
  • The Right to an Attorney: After your arrest, you can speak with a lawyer before answering any questions. You should request an attorney directly and avoid making any statements until your lawyer is present.
  • The Right to Refuse a Preliminary Alcohol Screening (PAS) Test: Unless you are under 21 or on probation for a previous DUI, you can refuse a handheld breathalyzer test before being formally arrested. However, you must submit to a chemical test (breath or blood) under California's implied consent law after a lawful arrest.

What are the DUI Penalties in California? 

The penalties you will face in any drunk driving case will depend on the actual charge, whether you have previous convictions, and any aggravating factors, such as having caused property damage, injury, or death to another. You may also face additional charges if you were found driving under the influence with a minor in your vehicle, known as DUI with child endangerment.

Penalties can include jail time, probation, fines, community service, DMV license suspension, DUI “school,” drug or alcohol testing, drug or alcohol treatment and education, court fees, SR-22 insurance, and restricted licenses requiring ignition interlock devices. 

First-Offense DUI 

  • Up to 6 months in jail
  • Fines of up to $1,000
  • License suspension for up to 6 months
  • Mandatory attendance to DUI school

Additionally, if the offense involves a blood alcohol concentration (BAC) of 0.15% or higher, the driver may also be required to install an ignition interlock device on their vehicle.

Second-Offense DUI 

  • Up to 1 year in jail
  • Fines ranging from $390 to $1,000
  • License suspension for up to 2 years
  • Mandatory installation of an ignition interlock device
  • Mandatory completion of an 18-month - 30-month DUI school

Third-Offense DUI 

  • Up to 1 year in jail
  • Fines ranging from $390 to $1,000
  • License suspension of up to 3 years
  • Installation of an ignition interlock device (IID)
  • Mandatory completion of an 18-month - 30-month DUI school
  • Possible vehicle impoundment

Felony DUI 

A felony DUI charge is typically given in instances where there is bodily harm to another person or extensive property damage. A felony DUI can be charged when the DUI is a 4th offense within 10 years or there has been a previous felony DUI conviction.

  • 16 months to 4 years in California state prison
  • Up to $5,000 in fines
  • Could lose driver’s license for up to 5 years
  • Mandatory completion of an 18-month - 30-month DUI school

Defenses Against DUI Charges

Common defenses include:

  • Improper Traffic Stop: Law enforcement will need to have a valid reason to stop your vehicle. If the officer had lacked reasonable suspicion to make the traffic stop, any evidence gathered after the stop may be inadmissible in court.
  • Faulty Field Sobriety Tests: Field sobriety tests are often used to justify an arrest but are far from perfect. Factors like poor lighting, uneven surfaces, medical conditions, and even nervousness can lead to poor performance unrelated to intoxication.
  • Inaccurate Breath or Blood Testing: Breathalyzers and blood tests must be properly administered and maintained according to strict protocols. Mishandled equipment, improper calibration, or contamination of blood samples can result in inaccurate readings.
  • Rising Blood Alcohol Concentration (BAC): Alcohol absorption varies from person to person. It is possible that your BAC was under the legal limit while you were driving but rose above the limit by the time you were tested.
  • Violation of Constitutional Rights: If your rights had been violated at any point during the stop, arrest, or investigation—for example, if you were not informed of your right to remain silent or if you were subjected to an illegal search—the evidence obtained may be thrown out.

Frequently Asked Questions

Will I lose my driver’s license right after a DUI arrest?

Possibly, and it can happen sooner than most people expect. When you are arrested for DUI in California and submit to a chemical test or refuse one, the officer typically takes your license and issues a temporary 30-day permit. The DMV then moves to suspend your license separately from the criminal case. Acting quickly matters, because the right to challenge that suspension at a DMV hearing has a short deadline.

What is the DMV hearing, and why does the deadline matter?

After a DUI arrest, you have a limited window, generally 10 days from the date you receive the notice of suspension, to request an administrative hearing with the DMV. This hearing is separate from your criminal case and focuses on whether the arresting officer had reasonable cause to stop you and whether there was probable cause for the arrest. If you miss the deadline, your license is usually suspended automatically, so it’s important to contact an attorney right away.

Do I have to appear in court after a DUI arrest?

Yes. Your first court appearance is usually an arraignment, where you are formally informed of the charges and enter a plea. Missing this hearing can lead to a bench warrant for your arrest and additional problems with your case. Your attorney can often appear on your behalf for certain hearings, but that depends on the court and the stage of the case, so it’s important to confirm with your lawyer what you need to attend.

Can I still drive after a DUI arrest?

It depends on what the DMV has done with your license. If you received a temporary permit and your license has not yet been suspended, you may be able to drive while the case is pending, but that can change quickly. If your license has been suspended, driving can result in new charges, including driving on a suspended license, which can be more serious than the original DUI. Do not drive until you know your license status.

Can I be charged with a DUI if my blood alcohol was under 0.08%?

Yes. A BAC below the legal limit does not automatically protect you. California law also prohibits driving while impaired by alcohol, drugs, or a combination of both, even if your BAC is under 0.08%. Prosecutors may rely on officer observations, driving behavior, and field sobriety tests to prove impairment, which is why every case requires a careful review of the evidence.

How long does a DUI stay on my record?

A DUI conviction generally remains on your criminal record permanently, and it can affect future charges, sentencing, and some employment or licensing decisions. Its impact on your driving record and insurance rates also lasts for years. Certain forms of post-conviction relief may be available once probation is completed, but the conviction is not erased from every record, so it’s wise to discuss long-term consequences early in your case.

Can a DUI be dismissed or expunged?

In some cases, yes. Depending on the circumstances, the charges may be reduced, dismissed, or resolved through negotiation, and eligible defendants may later petition the court for relief under California Penal Code section 1203.4 after completing probation. Relief of this kind does not erase the DMV record or permanently remove the case from every database, so the outcome should be discussed in detail with an attorney.

Will a DUI affect my job or professional license?

It can. Employers, licensing boards, and background checks may review a DUI arrest or conviction, and certain professions, including those requiring commercial driving, healthcare, law, or other state-issued licenses, may have additional reporting requirements. The impact depends on the specific charge, your occupation, and whether your case is resolved in a way that limits the record. Our attorneys can help you think through these consequences before you make decisions about your case.

What should I do in the first few hours after a DUI arrest?

Stay calm, be polite with officers, and avoid discussing the details of your night or your drinking with anyone other than your attorney. Exercise your right to remain silent and request a lawyer. Write down everything you remember about the stop, the arrest, and any tests, including the location, time, and what was said, as soon as you are able. Then contact a DUI attorney quickly, because evidence and deadlines can move fast.

How much does it cost to hire a DUI lawyer in Napa County?

Fees vary depending on the complexity of the charges, whether the case is expected to go to trial, and whether there are prior offenses or injuries involved. Wilber Law Offices offers a free initial consultation, which gives you the opportunity to discuss your situation, ask questions, and understand your options before committing to representation. During that conversation, our team can explain how fees are structured for your specific case.
