How Much Does a DUI Really Cost in California? (Full Breakdown)
When people get arrested for a DUI in California, the first number they hear is usually something like $390 — that’s the base fine listed in the law.
That number is almost meaningless.
By the time you add up fines, penalties, fees, programs, insurance, and everything else, a first-offense DUI in California typically runs $9,000 to $15,000 total. Some people end up much higher. Here’s where it all goes.
The Court Fine — What the State Charges You
The base fine for a first DUI is $390 to $1,000. But California courts add a pile of assessments, surcharges, and fees on top of the base fine. Here’s how the math actually works:
| Item | Amount |
|---|---|
| Base fine | $390–$1,000 |
| State penalty assessment (×3) | adds ~$1,170–$3,000 |
| County penalty assessment | adds more |
| Court construction fee | ~$35 |
| Other surcharges | varies |
| Total fines | ~$1,800–$3,500 |
Some counties run higher than others. Orange County tends to be more expensive than average; rural counties often less so.
DUI School (Required)
First-time DUI with BAC under 0.15%: you’ll likely be ordered into a 3-month DUI program.
BAC of 0.15% or above: usually a 9-month program.
Cost: $500–$700 for 3 months. Up to $1,500–$1,800 for 9 months.
You pay out of pocket. These programs have set fees and you attend classes, counseling, and sometimes AA meetings. Miss sessions, and you risk violating probation.
Attorney Fees
If you hire a private attorney (recommended for anyone who wants to fight the charge or negotiate a reduction):
- Basic representation: $1,500–$2,500
- Contested case with DMV hearing: $2,500–$4,000+
- Trial: $5,000–$10,000+
You can represent yourself, but most people who try it describe it as stressful and rarely effective against experienced prosecutors.
Public defenders are free but have enormous caseloads and very little time for your case.
Car Insurance (This is Often the Biggest Hit)
This is where people get shocked.
After a DUI conviction, you’ll need an SR-22 certificate — a form your insurance company files with the state proving you have coverage. Many standard insurers drop you outright.
When you find a new policy:
- Expect rates to double or triple immediately
- You’ll need to maintain the SR-22 for 3 years
- That premium increase lasts 5–10 years on your record
For someone paying $1,200/year normally, that might jump to $3,000–$4,500/year. Over 5 years: an extra $10,000–$15,000 in insurance alone.
License Reinstatement Fee
After your suspension ends, you have to pay the DMV to get your license back: ~$125.
If you had your license revoked (more serious cases), the fees are higher and the process more involved.
Ignition Interlock Device (IID)
An IID is a breathalyzer installed in your car. You have to blow into it before the car will start, and periodically while driving.
- Installation: ~$75–$150
- Monthly rental and monitoring: ~$70–$100/month
- Typically required for 6 months to 1 year for first offenses
Total IID cost: $500–$1,300+
Some counties now require IIDs for all first-time DUI convictions. Others only require them in certain circumstances.
Towing and Impound
Your car gets towed when you’re arrested. You pay:
- Tow fee: ~$150–$250
- Storage per day: $50–$100/day
- Release fees: varies
If your car sat for two days before you got out: you’re looking at $300–$500 just to get it back.
Time Off Work
This is harder to calculate but very real:
- Court appearances (multiple, usually)
- DMV hearing
- DUI school sessions (often weekday evenings or Saturdays)
- Meetings with your lawyer
For someone who misses a half-day per appointment: that’s easily $1,000–$3,000 in lost wages or PTO over 6–12 months.
Putting It All Together
Here’s a realistic first-offense total:
| Item | Estimate |
|---|---|
| Court fines and fees | $2,000–$3,500 |
| DUI school (3–9 months) | $500–$1,800 |
| Attorney fees | $1,500–$4,000 |
| Insurance increase (Year 1) | $1,500–$3,000 |
| IID | $500–$1,300 |
| Towing/impound | $300–$500 |
| License reinstatement | $125 |
| Lost wages | $500–$3,000 |
| Total (Year 1) | ~$7,000–$17,000 |
And that’s just year one. The insurance hit continues for years.
The “Just a First Offense” Mistake
The phrase “it’s just a first offense” leads a lot of people to underestimate this.
A first offense in California is a misdemeanor. It stays on your driving record for 10 years. It shows up on background checks. It affects your insurance for years.
It also becomes a prior if you’re ever arrested again — which dramatically increases penalties on any future charge.
Understanding the full financial picture early helps you make better decisions: whether to fight the charge, negotiate a reduction, or understand what a guilty plea actually means for your wallet.
