The penalties for a first-time DUI in California include a base fine of $390 to $1,000 (roughly $1,800 to $4,000 after assessments), a minimum of 96 hours and up to six months in county jail, three to five years of informal probation, a six-month license suspension, and a mandatory alcohol education program lasting three or nine months depending on your BAC. Once you add attorney fees, insurance increases, the ignition interlock device, and lost wages, the all-in cost of a first offense typically runs $16,000 to $20,000. The conviction stays on your record and counts as a prior for ten years.
What the Fine Actually Costs
The statutory base fine runs $390 to $1,000, set by the judge at sentencing.1California Legislative Information. California Vehicle Code 23536 Then California’s penalty assessments take over. The state adds a $10 surcharge for every $10 of base fine, the county adds $7 per $10, and further surcharges fund court construction, DNA identification, and alcohol abuse prevention programs.2California Courts. Crosswalk Guide – Penalty Assessment Calculations
The upshot: a $390 base fine grows to roughly $1,800, and a $1,000 base fine can pass $4,000 once every assessment is applied. Expect additional booking fees, a victim restitution fund contribution, and a fee for the DUI victim impact panel.
Jail Time
The law requires a minimum of 96 hours in county jail, with at least 48 hours served continuously, and permits up to six months.1California Legislative Information. California Vehicle Code 23536 In practice, first-time offenders without aggravating factors serve far less than the maximum. Judges routinely allow community service, work release, or electronic monitoring in place of extended jail. For someone with a BAC just over the legal limit, no accident, and a clean record, actual custody time is often limited to the 48-hour minimum or replaced entirely by alternative sentencing.
Aggravating factors change that quickly. If a child under 14 was in the vehicle, the court must add 48 continuous hours of jail that cannot be suspended or reduced.3California Legislative Information. California Vehicle Code 23572 A BAC of 0.15% or higher, or a refusal to take a chemical test, is treated as a special factor that justifies enhanced penalties and stricter probation conditions.4California Legislative Information. California Vehicle Code 23578
License Suspension and Driving Again
A first-time DUI arrest triggers two separate license actions that run on parallel tracks. You need to satisfy both to fully restore your driving privileges.
The DMV Administrative Suspension
Under California’s Administrative Per Se law, the DMV suspends your license based on the arrest alone, regardless of what happens in court. A BAC of 0.08% or higher brings a four-month suspension. Refusing the chemical test brings a full year.5California Department of Motor Vehicles. DUI First Offender Alcohol Involved – Non-Injury 21 and Older The arresting officer takes your license on the spot and issues a temporary one valid for 30 days.6California State Department of Motor Vehicles. California Driver Handbook – Section 9: Alcohol and Drugs
You have only 10 days from arrest to request a DMV hearing to challenge the suspension. Miss that window and the suspension takes effect automatically.
The Court-Ordered Suspension
A conviction adds a separate six-month suspension.7California Legislative Information. California Vehicle Code 13352 Because the two suspensions generally run at the same time, most first-time offenders face six months without a full license, not ten.
Getting a Restricted License
After a mandatory 30-day “hard” suspension when you cannot drive at all, two paths open up. You can apply for a traditional restricted license, which limits you to driving to and from work, during work hours, and to your DUI program. This requires proof of program enrollment and an SR-22 certificate on file with your insurer. Or you can install an ignition interlock device and apply for an IID-restricted license right away, which lets you drive anywhere as long as the vehicle has the device.5California Department of Motor Vehicles. DUI First Offender Alcohol Involved – Non-Injury 21 and Older
The SR-22 must stay in place for three years. The filing fee itself is $25 to $50, but the insurance premium increase behind it is the real expense. DMV reinstatement fees run about $125.
The Ignition Interlock Device
For a first offense without injury, an IID is not strictly mandatory, but installing one is the fastest way back to unrestricted driving. The court may order one for up to six months. If your DUI involved injury, IID installation is mandatory for one year.8California State Department of Motor Vehicles. Statewide Ignition Interlock Device Program
The device functions as a breathalyzer wired into the ignition, blocking the engine from starting if it detects alcohol and requiring periodic rolling retests while you drive. Installation runs $70 to $150. Monthly calibration and monitoring fees are $60 to $80. Over six months, plan on $430 to $630 for the device, plus DMV administrative service fees of $103 to $125 for the IID license.
The Mandatory Alcohol Program
Every first-time conviction includes a DUI education program, and its length turns on your BAC at arrest. Below 0.20%, the court assigns a three-month program of at least 30 hours combining education, group counseling, and individual sessions. At 0.20% or above, or with a test refusal, the program stretches to nine months and at least 60 hours.9California Legislative Information. California Vehicle Code 23538
Costs vary by county and provider. A three-month program typically runs $500 to $1,100. A nine-month program can cost $1,800 to $2,500. The court may order a longer program if your BAC was 0.15% or higher, since that level is treated as a special factor.4California Legislative Information. California Vehicle Code 23578 Enrollment must happen promptly after sentencing, and completion is a prerequisite for full license reinstatement.
Probation
Almost every first-time DUI conviction carries three to five years of informal (unsupervised) misdemeanor probation. The conditions are firm. You cannot drive with any measurable amount of alcohol in your blood. You must submit to a chemical test if arrested for another DUI. You cannot commit any new criminal offense during the probation period.10California Legislative Information. California Vehicle Code 23600 Courts may add attendance at Alcoholics Anonymous meetings or a Mothers Against Drunk Driving victim impact panel.
Violating probation has teeth. If you fail to enroll in, attend, or complete the assigned DUI program, the court is required to revoke probation absent good cause.9California Legislative Information. California Vehicle Code 23538 Revocation can mean being resentenced to the original jail term that had been suspended.
The Full Financial Picture
Court-imposed fines and program fees are only part of the total. A first-time California DUI regularly costs $16,000 to $20,000 across the years that follow. The pieces:
- Fines and assessments: $1,800 to $4,000 or more, depending on the base fine and your county.
- DUI education program: $500 to $2,500, based on length.
- Ignition interlock device: $430 to $630 over six months, plus DMV fees.
- Attorney fees: roughly $2,500 to $4,000 for a straightforward first offense with private counsel; complex cases or trials can reach $10,000 or more.
- Insurance premium increases: the biggest long-term cost. California drivers typically see premiums jump sharply after a DUI, and the SR-22 requirement lasts three years. Cumulative increases of $5,000 to $15,000 or more are common.
- Towing and impound fees: $200 to $1,200.
- DMV reinstatement and restriction fees: $125 to $200.
- Lost wages from court appearances, jail, community service, and program sessions.
The IRS treats DUI fines, attorney fees, and related costs as personal expenses tied to a criminal matter, so none of it is tax-deductible.
The Wet Reckless Alternative
Not every DUI arrest ends in a DUI conviction. When the evidence has weaknesses, such as a borderline BAC, questionable field sobriety testing, or procedural errors, the prosecution may offer a plea to reckless driving involving alcohol under Vehicle Code 23103.5, commonly called a “wet reckless.”11California Legislative Information. California Vehicle Code 23103.5 A wet reckless carries lower fines, a shorter or no mandatory jail sentence, and a shorter education requirement.
The catch is priorability. A wet reckless counts as a prior DUI for enhancement purposes. If you’re arrested for DUI again within ten years, the earlier wet reckless will be treated as a first DUI when calculating mandatory minimum penalties on the new charge.11California Legislative Information. California Vehicle Code 23103.5
How Long It Follows You
A first-time DUI conviction is a misdemeanor that stays on your criminal record. Under California’s ten-year lookback rule, it counts as a prior for sentencing if you’re charged with another DUI within a decade of the arrest date. After ten years the prior “washes out” for mandatory sentencing enhancement, but the conviction itself does not drop off your record automatically.
Once probation is complete, you can petition for relief under Penal Code 1203.4. If granted, you withdraw your guilty plea, a not-guilty plea is entered, and the case is dismissed. For DUI, this relief is discretionary rather than automatic. Even when granted, the dismissal has limits: the conviction can still be used as a prior in any future prosecution, and you must still disclose it when applying for public office or a state or local license.12California Legislative Information. California Penal Code 1203.4 For most private employers, a granted 1203.4 dismissal means the conviction should not appear on a standard background check.
A Few Consequences People Don’t Expect
Some effects reach past the courtroom and the DMV. Commercial drivers should know that a DUI conviction in any vehicle, personal car included, triggers a mandatory one-year CDL disqualification under federal regulations.13United States Department of Transportation, Federal Motor Carrier Safety Administration. Disqualification of Drivers 383.51 Pilots holding an FAA certificate must send written notification to the FAA within 60 days of a license suspension and again within 60 days of a conviction; failure to report can lead to denial, suspension, or revocation of the airman certificate for up to a year.14Federal Aviation Administration. Airmen and Drug- and/or Alcohol-Related Motor Vehicle Actions Cross-border travel is affected too: Canada treats impaired driving as a serious criminal offense, and a single DUI conviction can make you criminally inadmissible.15Government of Canada. Overcome Criminal Convictions A DUI conviction, or even a pending charge, also disqualifies you from U.S. Trusted Traveler Programs like Global Entry, NEXUS, and SENTRI.16U.S. Customs and Border Protection. Eligibility for Global Entry
Between three to five years of probation, three years of SR-22 insurance, a ten-year lookback for DUI priors, and a conviction that remains on your record, a first offense in California is not something you serve out and move past in a season.
