How Much Does a DUI Really Cost in San Diego?

A line-by-line, conservatively estimated accounting of the true cost of a first-offense misdemeanor DUI.

By Marc S. Kohnen, San Diego criminal defense attorney  ·  Published

Search for the cost of a DUI and you will find numbers all over the map: some suspiciously low, some designed to frighten. The honest answer for a first-offense misdemeanor DUI in San Diego is that the total cost, spread over the years that follow, typically lands well into five figures. The court fine, the number most people fixate on, is usually one of the smallest line items.

This guide walks through each category conservatively, in ranges, because the exact numbers depend on your case, your insurer, and decisions made along the way. The purpose is not to alarm you, but to show where the money actually goes, because the full ledger points to one conclusion: the conviction is the expensive part, and that is why the defense matters.

Court Fines and Penalty Assessments

California Vehicle Code section 23536 sets the base fine for a first-offense misdemeanor DUI at roughly $390 to $1,000. If that were the whole story, a DUI would be a manageable expense. It is not.

California adds penalty assessments (a stack of state and county surcharges) on top of the base fine, and they typically multiply it several times over. A $390 base fine, after assessments and court fees, commonly becomes a total obligation of approximately $1,800 to $2,500. The pattern is consistent: whatever base fine you are quoted, the amount you actually pay the court will be substantially higher.

DUI School: The AB 541 Program and Its Longer Cousins

A first-offense DUI conviction requires completion of a state-licensed DUI education program, and the DMV will not fully reinstate your license without proof of completion.

Most first offenders are ordered into the three-month program commonly called AB 541, which involves roughly 30 or more hours of classes and typically costs approximately $600 to $900. If your blood alcohol content was 0.20 percent or higher, or if you refused chemical testing, the court will usually order the nine-month program instead, which typically runs approximately $1,200 to $1,900. Missed sessions carry make-up fees, and being dropped for absences can mean re-enrolling and paying again. It is also a time cost: months of classes that have to fit around work and family.

Insurance: The Largest Cost Most People Underestimate

The single biggest expense of a DUI conviction is almost never paid to a court. It is paid to your insurance company, a little at a time, for years.

After a DUI-related license action, the DMV requires you to file an SR-22 (a certificate of financial responsibility from your insurer) and to keep it on file, typically for three years. The filing fee itself is small, approximately $15 to $50. The expensive part is what the SR-22 represents: your insurer now knows about the DUI, California law generally disqualifies you from the good-driver discount, and the conviction stays on your California driving record for ten years.

Premium increases vary widely by carrier, but increases of approximately $1,000 to $3,000 or more per year are common after a first DUI. Over the three-year SR-22 period (and often well beyond it, since insurers can see the conviction for up to a decade), the cumulative added premium frequently reaches approximately $5,000 to $15,000 or more.

DMV Fees and License Reinstatement

Getting your license fully back involves its own fees. The DMV reissue fee after a DUI-related suspension is approximately $125, and if you apply for a restricted license during the suspension period, additional application fees apply. Budget approximately $100 to $300 in total DMV-related fees; confirm current amounts with the DMV.

One deadline worth flagging: you generally have only ten days from the arrest to request a DMV administrative hearing. Missing that window usually means the license suspension takes effect automatically, regardless of what later happens in court.

Ignition Interlock Devices Under SB 1046

Since 2019, under Senate Bill 1046, most first offenders whose DUI did not involve injury have a choice: an ignition interlock device for about six months in exchange for full driving privileges, or a standard restricted license limiting driving to work and the DUI program. If the DUI involved injury, an IID is generally required rather than optional.

An IID is a breath-testing device wired into your vehicle, and you pay for it yourself. Installation typically costs approximately $70 to $150, and monthly rental and calibration fees typically run approximately $60 to $100. That comes to approximately $500 to $1,000 over six months, plus a removal fee. California law provides income-based discounts on IID costs for drivers who qualify.

Towing, Impound, and the Day-One Costs

If your car was towed and impounded at arrest, the tow fee plus daily storage typically totals approximately $250 to $500 or more by the time you retrieve it. Most first-offense misdemeanor DUI arrestees in San Diego are released on a citation without posting bail; where bail applies, a bond premium adds another expense. Then come the quieter costs of a suspension: rideshares to work, court, and DUI classes. None show up on a court invoice, but they are real money.

Lost Time and Lost Work

A DUI case consumes time most people have to take from work: court dates, the DMV hearing, months of DUI school, and any court-ordered community service. For hourly workers, several days of missed wages add up quickly. For people with professional licenses, security clearances, or commercial driving jobs, a conviction can trigger separate licensing consequences with their own costs, which is worth discussing with a lawyer early.

Attorney Fees, Framed Honestly

If you qualify financially, you are entitled to a public defender, and California has eliminated the administrative fees once charged for that representation. Public defenders in San Diego are experienced criminal lawyers who handle DUI cases every day. But eligibility is income-based, caseloads are heavy, and public defenders generally do not represent you at the separate DMV hearing that decides your license.

Private attorney fees for a first-offense misdemeanor DUI in San Diego commonly range from approximately $2,500 to $7,500, with contested cases involving motions, forensic witnesses, or trial preparation costing more. The most useful question is not which quote is lowest, but what the fee covers. Does it include the DMV hearing? Investigating the stop and the testing procedures, and filing suppression motions if the facts support them? Trial, or does trial cost extra? A very low flat fee sometimes reflects a plan to resolve the case quickly by plea; a higher fee often reflects preparation to litigate. Neither is inherently wrong, but you should know which you are buying, because that difference can determine whether the five-figure costs above ever come due.

When the Numbers Go Up

Everything above describes a standard first offense. Certain facts push every category higher.

  • A second or third offense within ten years brings longer license actions, a mandatory ignition interlock period of roughly a year or more, and the 18-month multiple-offender program, typically approximately $1,800 to $3,000.
  • A BAC of 0.20 percent or higher usually means the nine-month DUI school and a harder negotiating posture from prosecutors.
  • An accident adds repairs, restitution, and a larger insurance impact; an injury accident can be charged as a felony, which changes the financial picture entirely.
  • Refusing the chemical test typically triggers a one-year suspension with no restricted-license option for a first offense, plus additional penalties. The refusal is often costlier than the test result would have been.

How a Better Outcome Changes the Math

A DUI charge is not automatically a DUI conviction, and the gap between the two is measured in thousands of dollars.

The most common negotiated reduction is a wet reckless under Vehicle Code section 23103.5. Compared with a DUI conviction, a wet reckless typically means a lower base fine, a much shorter education program (often around six weeks, at approximately $250 to $500), no court-ordered ignition interlock arising from the conviction itself, and no mandatory DUI-conviction suspension from the court, although the DMV's administrative action on your license is a separate track. Insurance consequences of a wet reckless vary by carrier but are frequently less severe. A dry reckless improves the math further, and an outright dismissal, a won suppression motion, or a victory at the DMV hearing can take most of these costs off the table entirely.

No lawyer can promise any of those outcomes. The facts of each case control what is achievable. But the reason to take the defense seriously is arithmetic, not fear: nearly every cost in this guide is a cost of conviction, not of arrest.

Adding It All Up

Put the pieces together for a typical first-offense conviction: approximately $1,800 to $2,500 to the court, $600 to $1,900 for DUI school, $100 to $300 to the DMV, $500 to $1,000 for an interlock device if that route applies, a few hundred dollars in towing and day-one costs, lost work time, and the largest item of all, approximately $5,000 to $15,000 or more in added insurance premiums. A conservative total lands at approximately $10,000 to $18,000 or more, stretched over three to ten years.

Seen that way, the useful comparison is what a conviction costs measured against what a defense costs, and whether your case offers a path to something better.

Frequently Asked Questions

Is a public defender free?

For those who qualify financially, yes. California has repealed the administrative fees counties once charged for public defender representation. The catch is scope: public defenders handle the criminal case but generally do not appear at the separate DMV hearing that decides your license, which still must be requested within ten days and handled on its own.

Does my insurance company always find out about a DUI?

Not necessarily on day one, but almost always eventually. The SR-22 requirement effectively tells your insurer about the DUI, because the certificate has to come from the insurer itself. Even without an SR-22, insurers routinely pull driving records at renewal, and a DUI stays on your California driving record for ten years. Reducing or avoiding the conviction is the only reliable way to limit the insurance impact.

Can I just plead guilty quickly and save money?

Pleading guilty at the first opportunity saves time in court, but it locks in every downstream cost in this guide (fines, DUI school, the SR-22, the insurance increases, and the record itself) before anyone has examined whether the stop was lawful, the testing was reliable, or a reduction was available. Sometimes an early resolution genuinely is the right call; the point is to make that decision knowing what it costs, not because the fine looked manageable in isolation.

Are payment plans available for DUI fines?

Generally yes. San Diego courts commonly allow fines to be paid in installments and can consider your ability to pay. DUI program providers often offer payment schedules, and ignition interlock providers must offer income-based pricing to drivers who qualify. Spreading payments out helps with cash flow, but it does not reduce the totals, which is why the outcome of the case matters more than the payment terms.
