Getting a DUI in California is one of the most expensive misdemeanor convictions in the United States. If you are asking "how much is a DUI in California?" the answer goes far beyond what you pay in court. The true California DUI cost includes base fines, penalty assessments, court fees, mandatory DUI school, an ignition interlock device, SR-22 insurance, and years of increased premiums.
This guide provides a complete breakdown of California DUI fines in 2026 under CVC 23152. Whether you are facing a first offense or researching California DUI penalties for a repeat violation, you will find every cost, timeline, and legal option explained below.
How Much Does a DUI Cost in California in 2026?
The total cost of a DUI in California is far higher than most drivers expect. While the base fine starts at just $390, California's penalty assessment system multiplies every traffic fine by approximately 4–5 times. When you add DUI school, IID installation, SR-22 insurance, attorney fees, and lost wages, a first offense DUI California fine realistically costs between $10,000 and $15,800 over three years.
Here is why the number is so high: California imposes over a dozen separate surcharges on top of every base fine. These include state penalty assessments, court construction funds, DNA identification funds, emergency medical services surcharges, and county-specific add-ons. A $390 base fine becomes approximately $1,800 after these assessments are applied—and that is just the court portion.
California DUI Base Fines and Penalty Assessments
Under CVC 23152, California DUI base fines are set by the Vehicle Code, but the final amount you pay depends on penalty assessments mandated by state and county law. Understanding this distinction is critical because many drivers see the base fine and assume that is all they owe.
How the Penalty Assessment Multiplier Works
For every $10 of base fine, California adds roughly $40–$50 in penalty assessments. These are not optional—they are required by law. The major assessments include:
- State Penalty Assessment: $10 per $10 of base fine (100%)
- County Penalty Assessment: $7 per $10 of base fine (70%)
- Court Construction Fund: $5 per $10 of base fine (50%)
- DNA Identification Fund: $4 per $10 of base fine (40%)
- EMS Fund: $2 per $10 of base fine (20%)
- State Surcharge: 20% of base fine
- Court Operations Assessment: $40 flat fee per conviction
- Criminal Conviction Assessment: $35 flat fee per conviction
This is why a $390 base fine for a California DUI penalty totals approximately $1,800–$2,600 at the courthouse. In some counties, additional local assessments push the total even higher.
Total Cost of a First DUI Offense in California
The following table provides a detailed breakdown of every direct and indirect cost associated with a first offense DUI in California in 2026:
| Cost Type | Estimated Cost |
|---|---|
| Base Fine | $390 – $1,000 |
| Penalty Assessments | $1,400 – $1,600 |
| Court Fees (operations + conviction assessments) | $75 – $400 |
| DUI School (3-month AB 541 program) | $500 |
| Ignition Interlock Device – IID (6 months) | $500 – $1,500 |
| Towing & Vehicle Impound | $300 – $700 |
| License Reinstatement Fee | $125 |
| SR-22 Insurance Filing Fee | $15 – $50 |
| Insurance Premium Increase (3 years) | $3,600 – $6,000 |
| DUI Attorney Fees (if hired) | $2,500 – $5,000 (Detailed DUI cost breakdown) |
| Lost Wages (court dates, DUI school, jail) | $500 – $2,000 |
| Total Estimated Cost (1st Offense) | $10,000 – $15,800 |
As the table shows, the California DUI court fees and base fine represent only a small fraction of the total financial impact. Insurance increases alone can cost more than every other category combined.
Additional Costs After a DUI in California
Beyond the immediate court fines, several ongoing costs continue for months or years after a California DUI conviction.
SR-22 Insurance Requirement
After a DUI conviction, the California DMV requires you to file an SR-22 Certificate of Financial Responsibility for three years. This form proves you carry at least the state minimum liability coverage (15/30/5). While the SR-22 filing fee itself is small ($15–$50), the real cost is the insurance premium increase.
In 2026, California drivers with a DUI conviction see insurance premium increases of 80% to 150%. For a driver previously paying $1,800 per year:
- Pre-DUI annual premium: $1,800
- Post-DUI annual premium: $3,600 – $4,500
- Additional cost per year: $1,800 – $2,700
- Additional cost over 3 years: $5,400 – $8,100
Some drivers are dropped by their current insurer entirely and must seek high-risk specialty policies at even higher rates.
Ignition Interlock Device (IID)
California requires all DUI offenders statewide to install an IID as a condition of obtaining a restricted license. The device costs $70–$150 to install, $60–$100 per month for monitoring, $25–$50 every 60 days for calibration, and $50–$100 to remove. For a first-offense 6-month requirement, the total IID cost is typically $500–$1,500.
DUI School Programs
California mandates completion of a licensed DUI education program. The length and cost depend on the offense level:
| Offense | Program | Duration | Cost |
|---|---|---|---|
| 1st Offense | AB 541 | 3 months | ~$500 |
| 1st Offense (BAC 0.20%+) | AB 762 | 9 months | ~$1,200 |
| 2nd Offense | SB 38 | 18 months | ~$1,800 |
| 3rd Offense | SB 1176 | 30 months | ~$2,500 |
License Suspension and DMV Penalties
A California DUI triggers two separate license actions—one from the court and one from the DMV. These run independently, and losing one does not affect the other.
DMV Administrative Per Se (APS) Suspension
When you are arrested for DUI, the officer confiscates your physical license and issues a pink temporary license valid for 30 days. You have exactly 10 calendar days to contact the DMV and request an APS hearing. If you do not request this hearing, your license is automatically suspended on day 30.
Suspension Periods by Offense
| Offense | License Action | Hard Suspension | IID Period |
|---|---|---|---|
| 1st DUI | 4-month suspension | 30 days | 6 months |
| 2nd DUI (10-year lookback) | 2-year suspension | 90 days | 1 year |
| 3rd DUI (10-year lookback) | 3-year revocation | 6 months | 2 years |
| Chemical Test Refusal (1st) | 1-year hard suspension | 12 months | N/A (no restricted license) |
Jail Time for DUI in California
Jail time is a possibility for every DUI conviction in California, though many first offenders avoid it through plea deals and probation.
- 1st Offense: 48 hours to 6 months. Most first offenders receive summary probation with no actual jail time, or credit for time served at booking.
- 2nd Offense: 96 hours to 1 year. Minimum 96-hour jail requirement is mandatory and cannot be waived by the judge.
- 3rd Offense: 120 days to 1 year. Significant jail time is standard for third offenders.
- 4th+ Offense (Felony): 16 months to 3 years in state prison. A fourth DUI within 10 years can be charged as a felony under CVC §23550.
- DUI with Injury (CVC §23153): Can be charged as a felony even for a first offense, carrying 2–4 years in state prison plus victim restitution.
How to Reduce a DUI Penalty in California
While a DUI conviction carries severe California DUI penalties in 2026, several legal strategies can reduce the impact:
1. Plea Bargain to a "Wet Reckless" (CVC §23103.5)
The most common DUI reduction is a plea to "Wet Reckless." This typically results in lower fines ($1,000–$1,800 total), shorter probation (1–2 years), a shorter DUI school (6 weeks), and no court-mandated license suspension. However, a Wet Reckless still counts as a prior DUI within the 10-year lookback period.
2. Request the DMV APS Hearing
Requesting the APS hearing within 10 days gives you a chance to challenge the license suspension independently of the criminal case. If the arresting officer fails to appear or the DMV cannot establish proper procedures, the suspension may be overturned.
3. Challenge the Evidence
Effective defense strategies include:
- Challenging breathalyzer calibration and maintenance records
- Questioning the legality of the initial traffic stop
- Disputing field sobriety test administration procedures
- Presenting evidence of rising blood alcohol (BAC was below 0.08% at the time of driving but rose by the time of testing)
- Arguing mouth alcohol contamination of the breath sample
4. DUI Diversion Programs
Some California counties offer pre-trial DUI diversion programs for first offenders. Successful completion results in charges being dismissed entirely. Availability varies by county—consult with a local DUI attorney to determine if your jurisdiction offers this option.
Second and Third Offense DUI Penalties Comparison

|---|---|---|---|
