Vehicle Code 23152(b) VC – Driving With a BAC .08 or Greater

Vehicle Code 23152(b) VC is the Calfornia statute that makes it “unlawful for a person who has 0.08 percent or more, by weight, of alcohol in his or her blood to drive a vehicle.” This offense is a misdemeanor punishable by probation, fines, DUI school, a license suspension, an ignition interlock device and sometimes jail or work release.

Section 23152(b) VC is referred to as California’s “per se” DUI law. This means that motorists can be charged with this offense for driving with an excessive BAC, regardless of whether they are actually intoxicated or whether their driving ability is actually impaired. BAC is measured by either a breath test or a blood test.

Motorists arrested for DUI in California are frequently charged with this section as well as Vehicle Code 23152(a) VC – driving under the influence. These are considered two separate crimes. But even if you are convicted of both of them based on the same incident, it only counts as one DUI conviction on your record.

1. What does VC 23152(b) prohibit?

California Vehicle Code 23152(b) VC forbids driving with a BAC of at least 0.08%. It does not matter if the driver has a high alcohol tolerance and is driving safely without being impaired from the alcohol. Driving with an illegal BAC is per se illegal.¹

This crime has two elements that prosecutors must show:

1. The defendant was driving an automobile, and
2. The defendant had a BAC of 0.08% or greater.²

To prove BAC, prosecutors rely on the results of the breath test or blood test that DUI defendants take following their arrest.³ Prosecutors do not need any circumstantial evidence – such as bad driving or slurred speech – to show that the defendant was drunk. Sober people can have a BAC level above the legal limit.

In California, DUI suspects typically face charges for two separate offenses:

1. Driving with a BAC of 0.08% or greater (VC 23152(b)) – an objective standard that rests on BAC
2. Driving under the influence of alcohol (VC 23152(a)) – a subjective standard that does not depend on BAC

By prosecuting DUI suspects with both these charges, the D.A. gets “two bites of the apple” when trying to convict the defendant. But even when defendants commit both drunk driving and driving with a blood alcohol level of 0.08% or higher, defendants are convicted of just one crime. In short, the two DUI offenses combine into one.⁴

2. What are the best defenses in California?

3. What penalties can the judge sentence me to?

Violating VC 23152(b) is typically a misdemeanor unless the defendant has a prior felony DUI conviction or the incident resulted in a serious injury. The DUI penalties grow harsher with each successive conviction, and they vary by county.

Driving under the influence offense	California punishments*
First time DUI in 10 years	3 to 5 years of summary probation (typically 3 years); DUI school If BAC is lower than 0.20%, 3 months of DUI school, which is about 30 hours; If BAC is 0.20% or greater, 9 months of DUI school, which is about 90 hours Victim Impact Panel attendance; $390 to $1,000 in fines, plus penalty assessments; 6-month driver’s license suspension, but defendants may usually drive right away if they install IID in their cars for 6 months; 48 hours to 6 months in jail (courts usually order no jail if they grant probation); and Work release (depending on the county)
Second time DUI in 10 years	3 to 5 years of summary probation; 18-month or 30-month DUI school course; $390 to $1,000 in fines, plus penalty assessments; 2-year driver’s license suspension, though defendants may usually drive right away with an IID in their cars for 1 year; and 96 hours to 1 year in jail (the judge may agree to grant house arrest or a work-program rather than jail)
Third time DUI in 10 years	3 to 5 years of summary probation; 30-month DUI school course; $390 to $1,000 in fines, plus penalty assessments; 3-year driver’s license suspension, though defendants may usually drive right away with an IID in their vehicles for 2 years; and 120 days to 1 year in county jail (the minimum jail sentence is 30 days if the court grants probation and orders a 30-month DUI school class)
*The sentence may increase in aggravating circumstances, such as by going over the speed limit while DUI (VC 23582), transporting a minor under 14 in the automobile (VC 23572), or driving with a BAC of 0.15% or greater.7

In addition, some DUI defendants may be banned from travel to Canada.⁸

In certain circumstances, the D.A. may agree to plea bargain DUI charges down to wet reckless (VC 23103.5) or dry reckless (VC 23103). Also read our article about felony DUI in California.

4. Can I avoid jail by doing probation?

In many cases, courts do grant DUI defendants summary probation in lieu of jail. But there is some mandatory jail sentences for second- or successive DUI convictions.

Summary probation (a.k.a. informal probation) usually spans three to five years. The terms of probation include:

• Abiding by the criminal sentence, such as paying the fines in full and completing DUI School;
• Driving with a 0.00% blood alcohol concentration;
• Agreeing to take any evidentiary breath or blood tests should the defendant get another DUI arrest; and
• Staying out of trouble (committing no other crimes)

In certain cases, the court will also order defendants to do the following:

• Attend Alcoholics Anonymous (AA) or Narcotics Anonymous (NA) meetings;
• Participate in the Mothers Against Drunk Driving (MADD) Victim Impact Program; and/or
• Paying the victims (if any) restitution⁹

Anyone who violates these probation terms risk being sent to jail. Read more about DUI probation violations.¹⁰

5. Will I still be able to drive?

Every DUI arrest results in a license suspension unless the defendant wins both:

1. The criminal case, and
2. The DMV hearing (which is in administrative matter separate from the criminal case)

Most defendants can continue driving right away if they get an IID installed.

Misdemeanor DUI case in California	Length of license suspension
First-time offense in 10 years	If the defendant is convicted in the criminal case, the suspension is for 6 months. If the defendant loses the DMV case but wins the criminal case, the suspension is for 4 months.
Second-time offense in 10 years	1 year as long as the defendant installs an IID. If not, then 2 years.
Third-time offense in 10 years	2 years as long as the defendant installs an IID. If not, then 3 years.11

6. Will my car insurance be affected?

Following a DUI, the defendant’s auto insurer will most likely increase premium rates. Defendant are not required to tell their insurance carriers about DUIs unless there was an accident.¹² But insurers often find out anyway through a background check or if the defendant applies for an SR-22 to get his/her license reinstated. Read more about DUIs and car insurance.

7. Can immigrant defendants be deported?

In general, misdemeanor offenses of DUI of alcohol are not crimes involving moral turpitude and are therefore not deportable.¹³ Read more about DUIs by non-citizens.

8. When can I expunge my record?

After DUI defendants finish their summary probation, they can ask the court to expunge their VC 23152(b) conviction.¹⁴ The main benefit of expungement is that the DUI case can no longer disqualify workers from being hired or promoted.¹⁵ However if the defendant picks up another DUI within 10 years, the court will still treat the expunged DUI as a prior offense and can impose harsher punishments.¹⁶
