California DUI Penalties by Offense: First, Second, Third, and Felony DUI

California imposes increasingly severe penalties for repeat DUI offenses. Understanding what you face is essential for making informed decisions about your case.

DUI penalties in California depend on several factors: whether it's a first or repeat offense, your blood alcohol concentration (BAC), whether anyone was injured, and other aggravating circumstances.

First DUI Offense in California

A first-time DUI is typically charged as a misdemeanor under California Vehicle Code 23152. While it's the least severe DUI charge, it still carries significant consequences.

First DUI Penalties

Jail TimeUp to 6 months (rarely imposed)
Fines$390 - $1,000 + penalty assessments
License Suspension6 months (DMV) / 4 months (Court)
DUI School3-9 months program
Probation3-5 years informal probation
IID RequirementRequired for restricted license

True Cost of a First DUI

With penalty assessments, insurance increases, DUI school fees, IID costs, and other expenses, a first DUI typically costs $10,000 - $15,000 or more.

Second DUI Offense (Within 10 Years)

A second DUI within 10 years of a prior DUI conviction significantly increases penalties. California counts any prior DUI conviction—including "wet reckless" pleas—when determining priors.

Second DUI Penalties

Jail Time96 hours - 1 year
Fines$390 - $1,000 + penalty assessments
License Suspension2 years
DUI School18-30 months program
Probation3-5 years informal probation
IID Requirement1 year mandatory

Third DUI Offense (Within 10 Years)

A third DUI within 10 years is still a misdemeanor but carries dramatically harsher penalties, including mandatory jail time and extended license revocation.

Third DUI Penalties

Jail Time120 days - 1 year
Fines$390 - $1,000 + penalty assessments
License Revocation3 years
DUI School30 months program
Probation3-5 years informal probation
IID Requirement2 years mandatory
HTO DesignationHabitual Traffic Offender status

Fourth or Subsequent DUI (Felony)

A fourth DUI within 10 years can be charged as a felony under California law. This represents a dramatic escalation in potential consequences.

Fourth DUI (Felony) Penalties

State Prison16 months, 2 years, or 3 years
FinesUp to $5,000 + penalty assessments
License Revocation4 years
DUI School30 months program
ProbationFormal (felony) probation
StrikeMay count under Three Strikes law

DUI with Injury (VC 23153)

Any DUI that causes injury to another person can be charged as a felony, even if it's your first offense. This is one of the most serious DUI charges in California.

Misdemeanor DUI with Injury

  • • 5 days - 1 year jail
  • • $390 - $5,000 fines
  • • 1-3 year license suspension
  • • 3-5 years probation
  • • Restitution to victims

Felony DUI with Injury

  • • 16 months - 16 years prison
  • • Additional 1-6 years per victim
  • • Up to $5,000 fines
  • • 5-year license revocation
