A first DUI arrest in California is a serious matter, but it is not the end of the road. Most first-offense DUIs are charged as misdemeanors, and an experienced criminal defense attorney can often negotiate reduced charges, minimize penalties, or in some cases get the case dismissed entirely. Understanding what you are facing — and what your options are — is the first step.
Criminal Penalties for a First DUI
Under California Vehicle Code § 23536, a first DUI conviction carries: a fine of $390 to $1,000 plus penalty assessments that can bring the total to $1,800–$3,600 or more; 3 to 5 years of informal probation; a first-offender DUI education program (AB541) of 3 months (or 9 months if BAC was 0.15% or higher); and up to 6 months in county jail, though jail time is often suspended in favor of probation for first offenders. The court may also order community service, a victim impact panel, and restitution if there was property damage.
License Consequences
A first DUI triggers two separate license actions. The DMV will suspend your license for 4 months under the Administrative Per Se process — you have 10 days from arrest to request a hearing. The court will also impose a 6-month license suspension upon conviction. California law allows first-time offenders to install an ignition interlock device (IID) and obtain a restricted license that permits driving to work, school, and DUI programs during the suspension period. In some counties, the IID program allows unrestricted driving.
Aggravating Factors That Increase Penalties
Several factors can increase the penalties for a first DUI: a BAC of 0.15% or higher triggers enhanced penalties including a longer DUI school program; refusing a chemical test adds a mandatory 48 hours in jail upon conviction; having a passenger under 14 in the vehicle adds a mandatory 48 hours in jail; speeding 20+ mph over the limit on a freeway or 30+ mph on a surface street adds a mandatory 60 days in jail; and causing injury to another person can elevate the charge to a felony.
Can a First DUI Be Reduced or Dismissed?
Yes — in appropriate cases. If the evidence of impairment is weak, the stop was unlawful, or there are problems with the chemical test results, an attorney may be able to get the charges dismissed entirely. More commonly, a first DUI can be negotiated down to a 'wet reckless' — a conviction for reckless driving with alcohol involved under Vehicle Code § 23103.5. A wet reckless carries lower fines, no mandatory DUI school, and no mandatory license suspension, though it does count as a prior if you are arrested for DUI again within 10 years.

How Attorney Kade Defends These Cases
- —Challenge the legality of the traffic stop — an unlawful stop means all evidence is suppressed
- —Attack the reliability of the breath or blood test results
- —Present medical or physiological evidence explaining observed symptoms of impairment
- —Negotiate a reduction to wet reckless when the evidence of impairment is borderline
- —Challenge the field sobriety test administration and scoring
- —Request a DMV APS hearing to fight the license suspension independently
- —Seek diversion or deferred entry of judgment if available in the jurisdiction
Frequently Asked Questions
Jail is possible but not inevitable for a first DUI. The statutory range is 48 hours to 6 months in county jail, but judges frequently convert jail time to community service, a work release program, or electronic monitoring for first-time offenders with no aggravating factors. An experienced attorney can often negotiate to avoid any actual jail time.
A first-offense DUI conviction typically results in a 6-month court-ordered license suspension. Separately, the DMV may impose a 4-month Administrative Per Se suspension if you did not win your DMV hearing. California law allows eligible first-time offenders to install an ignition interlock device (IID) and obtain a restricted license that permits driving to work, school, and DUI programs.
The total cost of a first DUI in California — including fines, penalty assessments, DUI school, DMV fees, insurance increases, and attorney fees — typically ranges from $10,000 to $25,000 or more over the course of probation. The base fine is $390, but penalty assessments multiply it to $1,800–$2,600 before adding other costs.
