What Are the Penalties for a Second DUI in California?

A second DUI conviction within 10 years of your first carries significantly harsher penalties than your initial offense. Under California Vehicle Code Section 23540, the court must impose mandatory minimum penalties that include jail time, fines, license suspension, and DUI education programs.

Vehicle Code section 23540 provides for 90 days to one year in county jail for a second DUI within 10 years. If the court grants probation, Vehicle Code section 23542 requires at least 10 days or at least 96 hours (served in two continuous 48-hour blocks), up to one year. Fines start at $390, but with penalty assessments and fees, you’ll actually pay between $1,800 and $2,800. The court will also order an 18-month or 30-month DUI program, depending on the circumstances of the case and the program the court orders.

For a second DUI conviction, California requires an IID restriction for a mandatory term (commonly 12 months) on vehicles the person operates. If you don’t install an IID (and don’t qualify for an exemption), you may be unable to drive during the suspension/restriction period and may be unable to fully reinstate your driving privilege until IID requirements are satisfied.

Key Takeaway: A second DUI within 10 years carries significant jail exposure (90 days to 1 year under the statute, with probation terms that can include at least 10 days or at least 96 hours), plus major fines, DUI school, and an IID requirement.

How Does a Second DUI Affect Your Driver's License?

If you’re 21 or older, took a chemical test showing 0.08% BAC or more, and this is your second (or subsequent) DUI arrest, the DMV will impose a 1-year APS suspension. You generally receive a 30-day temporary license upon arrest, and the suspension takes effect after that unless you request a hearing in time. This is a separate administrative action from your criminal case and happens regardless of whether you’re convicted in court. However, you can challenge this suspension at a DMV administrative hearing.

You have only 10 days from your arrest date to request a DMV hearing. Missing this deadline means your license is automatically suspended 30 days after your arrest. At the hearing, a DMV hearing officer reviews the evidence to determine whether the officer had a lawful basis and reasonable cause for the action, whether you were lawfully arrested, and whether your BAC was 0.08% or higher.

If you lose at the DMV hearing or don’t request one, you can apply for a restricted license after installing an IID. This restricted license allows you to drive anywhere in California as long as the IID is installed and functioning. Without installing the device, you face a complete two-year suspension with no driving privileges.

Professional Excellence When Everything's on the Line

Will You Go to Jail for a Second DUI?

Yes. Under California law, a second DUI conviction within 10 years requires mandatory jail time. The mandatory minimum sentence is 90 days; however, if probation is granted, the minimum becomes 96 hours, which must be served in two 48-hour periods. Additionally, judges can impose up to one year in county jail depending on the circumstances of your case.

Courts consider several factors when determining your jail sentence. If your blood alcohol concentration was significantly over the legal limit, if you refused chemical testing, if you were speeding excessively, or if a child under 14 was in your vehicle, the judge will likely impose a sentence closer to the maximum. Prior criminal history and any aggravating circumstances also influence the length of your sentence.

In some cases, judges allow alternative sentencing options instead of traditional jail time. These alternatives include:

  • Electronic monitoring: House arrest with an ankle bracelet that tracks your location
  • Work release programs: Serving your sentence while maintaining employment
  • Private pay jail: Housing in a facility with better conditions for a daily fee
  • Community service: Performing unpaid work instead of custody time

However, these alternatives are not guaranteed. The judge has complete discretion, and prosecutors often oppose alternative sentencing in second DUI cases. Your best chance of avoiding jail time or reducing your sentence is to challenge the DUI charge itself.

Key Takeaway: California law requires a mandatory minimum sentence of 90 days for a second DUI conviction, but a strong defense can potentially result in reduced charges or dismissal.

How Is a Second DUI Different From a First Offense?

A second DUI within 10 years is treated much more seriously than a first offense. The penalties double or triple across nearly every category, and judges show significantly less leniency when imposing sentences.

Jail Time Differences

First-time DUI offenders in California typically receive no jail time or only 48 hours. However, a second offense requires a mandatory minimum sentence of 90 days with the possibility of up to one year in jail. Judges rarely grant probation without custody time for a second offense, with the minimum custody time being 96 hours served over two 48-hour periods.

License Suspension Differences

A first DUI results in a six-month license suspension, while a second offense triggers a two-year suspension. First offenders can obtain a restricted license after 30 days with an IID, but second offenders may have to wait 90 days before becoming eligible for any driving privileges.

DUI School Requirements

First offenders complete a three-month or nine-month DUI education program. Second offenders must attend an 18-month or 30-month program, requiring weekly group sessions and individual counseling. These programs cost between $1,800 and $2,500 and take significantly more time to complete.

Financial Impact

Fines and fees for a first DUI typically total $1,000 to $2,000. A second offense increases this to $1,800 to $2,800, plus higher insurance premiums that can last for years. Your insurance company may classify you as a high-risk driver, resulting in premiums that triple or quadruple.

Key Takeaway: Second DUI penalties are approximately double those of a first offense, with mandatory jail time, longer license suspension, extended DUI school, and significantly higher costs.

What Defenses Work in Second DUI Cases?

A second DUI charge is serious, but it’s not a conviction. Strong defenses exist that can result in reduced charges, dismissal, or acquittal at trial. The key is examining every detail of your arrest to find weaknesses in the prosecution’s case.

Challenging the Traffic Stop

Police officers must have reasonable suspicion to pull you over. If the officer lacked a valid reason for the stop, any evidence gathered afterward may be inadmissible in court. Common invalid stop reasons include pulling you over based on a hunch, stopping you without observing a traffic violation, or extending a routine stop beyond its original purpose.

Questioning Field Sobriety Tests

Field sobriety tests are subjective and prone to error. Medical conditions, injuries, fatigue, nervousness, poor lighting, and uneven road surfaces can all cause you to fail these tests even when sober. Officers often fail to properly administer the tests according to standardized procedures, which can provide grounds for challenge.

Attacking Chemical Test Results

Blood and breath tests must be administered according to strict protocols. Title 17 of the California Code of Regulations establishes requirements for calibration, maintenance, observation periods, and chain of custody. Violations of these requirements can result in suppression of test results. Common issues include:

  • Improper calibration of the breath testing device
  • Blood samples that were contaminated or improperly stored
  • Testing devices that were not properly maintained
  • Failure to observe you for 15 minutes before a breath test
  • Blood draw performed by an unqualified technician

Rising Blood Alcohol Defense

Your blood alcohol concentration continues to rise for 30 to 90 minutes after your last drink. If you were stopped shortly after drinking, your BAC may have been under 0.08% while driving, but rose above the legal limit by the time you were tested. This “rising blood alcohol” defense can be powerful when supported by expert testimony.

Key Takeaway: Second DUI cases can be defended by challenging the traffic stop, questioning field sobriety tests, attacking chemical test errors, and proving your blood alcohol was rising after you stopped driving.

Frequently Asked Questions About Second DUI Offenses in San Diego

Yes. Prosecutors sometimes agree to reduce a second DUI to a “wet reckless” charge under Vehicle Code Section 23103.5. This reduction is more common when the prosecution’s evidence has weaknesses, such as a borderline BAC, problems with the traffic stop, or issues with chemical test results. A wet reckless conviction results in less jail time, lower fines, and a shorter probation period.

A DUI conviction remains on your California driving record for 10 years. After 10 years, it no longer counts as a prior conviction for sentencing purposes. However, the conviction stays on your criminal record permanently unless you obtain an expungement under Penal Code Section 1203.4 after completing probation.

You can refuse a preliminary alcohol screening test during a traffic stop without penalty (unless you’re under 21 or on DUI probation). However, refusing a chemical test after arrest triggers an automatic one-year license suspension for a first refusal or two years for a second refusal in ten years, in addition to any DUI penalties.

Yes. Insurance companies can increase your premiums significantly after a second DUI, often by 200% to 400%. You’ll also be required to file an SR-22 form, which is proof of financial responsibility, for three years. Some insurance companies may cancel your policy entirely, forcing you to find high-risk insurance that costs substantially more.

Yes, but only after successfully completing probation. Under Penal Code Section 1203.4, you can petition the court to withdraw your guilty plea or no-contest plea and dismiss the case. However, the DMV record remains, and the conviction still counts as a prior if you’re arrested for another DUI within 10 years.

California counts out-of-state DUI convictions as prior offenses. If you were convicted of DUI in another state within the past 10 years, California will treat your current DUI as a second offense and impose enhanced penalties accordingly.
