Felony DUI Laws (VC 23152) in California

California Vehicle Code 23152 – Driving under the Influence/Driving with a BAC of .08 or higher

Legal Definition: A DUI can be found in multiple ways, but most commonly, you can be found guilty of a DUI if you are found to be driving a vehicle under the influence of alcohol or a drug or you are driving a vehicle with a Blood Alcohol Content (BAC) of .08 or higher.

However, what elevates a DUI to a Felony under VC 23152, occurs if the person has suffered three or more prior DUI convictions within a 10-year period. If so, even if it is a relatively minor DUI offense, it will become an automatic Felony DUI.3 Ways a California DUI Can Be Charged as a Felony 

For a person to be convicted of a violation of VC 23152(a), the prosecution must prove the following:

  1. You drove a vehicle; AND
  2. When you drove, you were under the influence of (an alcoholic beverage/a drug) or under a combination of alcohol and drugs.

For a person to be convicted of a violation of VC 23152(b), the prosecution must prove the following:

  1. You drove a vehicle; AND
  2. When you drove, you were driving with a BAC of .08 or higher.

And, for your DUI arrest to elevate to a Felony charge, one of the following occur:

  1. A prior DUI conviction under VC 23152 is punishable as a felony if it was your fourth offense of DUI or Wet Reckless.
  2. You have a previous felony conviction of a DUI.
  3. A prior gross vehicular manslaughter under PC 192 (c)(1) where you were convicted of a felony.

What is the difference between the (a) and the (b) counts?

Most people who find themselves in a situation where they are facing a DUI arrest are confused to find that they were arrested for a violation of both of the above offenses. Although similar, they both require different elements to violate the law. For the (a) count, it is requiring that you were simply driving under the influence. A person is under the influence if, as a result of consuming drugs or alcohol, your mental or physical abilities are so impaired that you can no longer drive a vehicle with the caution of a sober person, using ordinary care, under similar

Thus, you can be arrested and charged with driving under the influence, even if you’re BAC is under the well-known limit of .08. Police tend to mistake driving late at night by a very tired person as someone who is under the influence. Thus, even if you are simply tired or exhausted from a long day at work, if it can be shown you had at least some measurable amount of alcohol or drugs in your system that affected your driving, you could still be convicted of this crime. That is why this specific offense is important because it is highly defensible to explain that you were not driving under the influence, but simply driving while tired.

For the (b) count, it is a bit more straightforward. If you were driving, and at some point, you complete a blood or breath test and receive a result of a BAC of .08 or higher, then you can be arrested for a violation of the (b) count. Therefore, it can exist where you were driving a vehicle with a BAC of .08 or higher, and also at that same time, were driving under the influence. You cannot be punished for both offenses, but you can be charged for both.


If convicted of a violation of VC 23152(a)/(b), as a felony, you could be sent to prison for upwards of 16 months, two years, or three years. You would be required to serve 50% of that sentence. You would also be subject to the same fines and fees, as well as an 18-month DUI class as you would in a misdemeanor DUI conviction. You would also suffer a Driver’s License suspension of up to four years with a conviction here.

However, as serious as these might be, the same general defenses apply to a Felony DUI as a misdemeanor DUI. Whether it be a bad stop by the police or a violation of your rights, the same elements of the crime exist for both offenses. In addition, if you did not suffer three DUIs within ten years previous to this fourth offense, you could not be convicted of a Felony DUI. It is up to the District Attorney’s Office to prove your prior offenses.


  1. Statute of Limitations
  2. Insufficient Evidence
  3. Violation of your Rights

If you have at least three prior DUI convictions, then your case will be a Felony. However, many of the same defenses are listed for misdemeanor DUIs. Another common defense that can be used is that police failed to meet the elements above for a conviction under this section.

If you get involve in an accident, and police are called, one of the obvious challenges will be for police to actually prove you were driving. This is easy if you are alone, in your car, in the middle of the night. This becomes harder if there are no witnesses, and you have multiple passengers in your car. One of my favorite examples of the issue here is imagining the police seeing a car weaving down a dark road. They initiate a stop, and by the time they arrive at the driver’s door, all three people in the car are sleeping in the back seat. So who was driving?

Many times this works in cases of hit and run, where you are driving late at night, and hit a mailbox or something where your car is totaled. You then leave the scene and police come knocking on your door the next day asking you about your car. There, police can likely show that you committed a hit and run, but likely by the time they speak to you, you’ve already sobered up. It is almost impossible at that point to prove you were driving for a DUI crime. It sounds simple, but as a local Ontario DUI attorney, I have seen it before, many times.

Facing a felony DUI charge is a significantly more severe matter compared to a misdemeanor offense, especially when it’s potentially your fourth DUI offense within a 10-year period. In such cases, the judicial system often adopts a tougher stance due to the repeat offender status, and the risk of a lengthy state prison sentence becomes a real possibility, as judges aim to protect public safety.

However, there are several mitigating factors that can influence the outcome of your case. Proactive steps like enrolling in an inpatient or outpatient rehabilitation program, attending AA/NA classes, or even beginning DUI classes early can significantly impact how your case is viewed by the court. These actions demonstrate a commitment to change and can be crucial in your defense.
