A conviction under California Vehicle Code 23153 for DUI causing injury carries penalties ranging from a few days in county jail on a first-offense probation sentence to multiple years in state prison, with escalating consequences for prior convictions, serious injuries, and multiple victims. Because the offense is a “wobbler,” the same statute can produce either a misdemeanor or a felony record. On top of the criminal sentence, you face license revocation, a mandatory ignition interlock device, court-ordered restitution to every injured person, and collateral effects that can outlast the case itself.
What the Prosecution Must Prove
Vehicle Code 23153 has four elements, and the prosecution must establish each one. The driver was under the influence of alcohol, drugs, or both. While driving impaired, the driver also committed a separate traffic violation or neglected a basic driving duty. That separate violation caused the collision. And someone other than the driver was injured.1California Legislative Information. California Vehicle Code 23153
The second element is where this charge diverges from a standard DUI. Being drunk behind the wheel isn’t enough on its own. Prosecutors must identify some other unlawful act happening at the same time: running a red light, speeding, an unsafe lane change, even failing to signal. The statute clarifies that they don’t have to name the specific code section violated to prove it.1California Legislative Information. California Vehicle Code 23153
The statute reaches impairment through several subdivisions. One targets general impairment where the driver’s ability to operate the vehicle safely was compromised. Another applies to anyone with a blood alcohol concentration of 0.08% or higher, whether or not they appeared impaired. Lower BAC thresholds apply to commercial drivers and drivers carrying passengers for hire, and separate provisions cover drugs and combined alcohol-and-drug impairment.1California Legislative Information. California Vehicle Code 23153
Misdemeanor or Felony
Because 23153 is a wobbler, the prosecutor decides whether to file the case as a misdemeanor or a felony. That decision turns on the severity of the victim’s injuries, the defendant’s BAC, and whether there are prior DUI-related convictions in the past ten years. Minor injuries and a clean record can keep the charge at the misdemeanor level. Serious injuries, a high BAC, or any prior DUI history tends to push the case into felony territory.
Once two or more prior DUI convictions exist within the ten-year window, the wobbler analysis ends. Under Vehicle Code 23566, a third or subsequent DUI with injury is automatically a felony carrying state prison time.2California Legislative Information. California Vehicle Code 23566
First-Offense Penalties
Even a first-time conviction under 23153 is more serious than a standard DUI. If the court sentences without granting probation, the term is 90 days to one year in state prison or county jail, plus a fine of $390 to $1,000.3California Legislative Information. California Vehicle Code 23554
Most first-time defendants receive probation instead. Probation carries mandatory conditions of its own: at least five days and up to one year in county jail, the same fine range of $390 to $1,000, and enrollment in a DUI education program. The program lasts three months for drivers whose BAC was below 0.20% and nine months for those at 0.20% or above.4California Legislative Information. California Vehicle Code 23556
The base fines understate the real cost. California adds penalty assessments, surcharges, and fees on top of every criminal fine, and a $390 base commonly ends up past $2,000 by the time everything is calculated.
Penalties With Prior Convictions
The look-back period is ten years. It counts any prior conviction for DUI under Vehicle Code 23152, DUI with injury under 23153, or wet reckless under 23103 as specified in 23103.5.
One Prior Conviction
A second DUI with injury is punishable by 120 days to one year in state prison or county jail and a fine of $390 to $5,000. The DMV revokes the license for three years.5California Legislative Information. California Vehicle Code 23560
Two or More Prior Convictions
With two or more priors, the offense is a straight felony carrying two, three, or four years in state prison and a fine of $1,015 to $5,000. License revocation stretches to five years, and the court designates the defendant a habitual traffic offender for three years after conviction.2California Legislative Information. California Vehicle Code 23566
A harsher layer applies when the injuries qualify as great bodily injury and the defendant has four or more prior DUI-related convictions within ten years. In that scenario the court adds three consecutive years in state prison on top of the base sentence.2California Legislative Information. California Vehicle Code 23566
Enhancements for Serious Harm and Multiple Victims
California law stacks additional prison time on top of the base sentence when the facts are especially severe.
Great Bodily Injury
Under Penal Code 12022.7, personally inflicting great bodily injury during a felony adds a consecutive three-year prison term. The statute defines great bodily injury as a significant or substantial physical injury, which courts have read to mean harm beyond minor or moderate, such as broken bones, concussions, or injuries requiring surgery.6California Legislative Information. California Penal Code 12022.7
When the victim is a child under five, the enhancement rises to four, five, or six years. In a domestic violence context, the range is three, four, or five years.6California Legislative Information. California Penal Code 12022.7
Multiple Victims
When more than one person is injured in the same incident, Vehicle Code 23558 adds one year in state prison for each additional victim beyond the first. This enhancement applies only to felony convictions, each additional victim’s injury must be specifically charged and proven, and the total is capped at three additional years no matter how many people were hurt.7California Legislative Information. California Vehicle Code 23558
The math adds up quickly. A defendant convicted of felony DUI with injury who caused great bodily injury to one person and injured three others could face four years on the base charge, three years for the great bodily injury enhancement, and three years for the additional victims. Ten years of potential prison exposure before any other enhancement enters the picture.
License Suspension, Revocation, and Ignition Interlock
The DMV acts independently of the criminal court. A judge can grant probation with minimal jail time and the DMV still suspends or revokes the license on its own schedule. These administrative penalties run alongside the criminal case, not after it.8California Department of Motor Vehicles. Driving Under the Influence
License loss under Vehicle Code 13352 tracks the number of prior offenses:
- First DUI with injury: one-year suspension
- Second DUI with injury within ten years: three-year revocation
- Third or subsequent DUI with injury: five-year revocation
A suspension is a temporary loss of driving privileges with an expected reinstatement. A revocation is a full termination that requires a new application to reinstate.9California Legislative Information. California Vehicle Code 13352
Anyone convicted under 23153 must also install an ignition interlock device, which requires a clean breath sample before the engine will start. The mandatory IID period runs 12 months for a first offense, 24 months for a second, 36 months for a third, and 48 months where there is a prior conviction under Vehicle Code 23550.5. The driver pays for installation and monitoring, and noncompliance blocks any path back to restricted driving privileges.10California Legislative Information. California Vehicle Code 23575.3
Restitution to Victims and the State
Under Penal Code 1202.4, the court must order full restitution to every victim who suffers economic loss. This is not optional and cannot be waived on the ground that the defendant cannot pay. The order covers medical bills, lost wages, rehabilitation costs, and any other economic harm flowing from the collision. If the total is unknown at sentencing, the court keeps the order open and sets the amount later.11California Legislative Information. California Penal Code 1202.4
Restitution orders are enforceable as civil judgments. Victims can collect through wage garnishment, bank levies, and other tools if the defendant doesn’t pay voluntarily. The obligation outlasts probation and can follow a defendant for years after the criminal case closes.11California Legislative Information. California Penal Code 1202.4
Separate from victim restitution, the court imposes a restitution fine payable to the state. For a felony conviction the fine runs from $300 to $10,000. For a misdemeanor, from $150 to $1,000. The court must impose it in every case unless it finds compelling and extraordinary reasons not to, and inability to pay is expressly not one of them.11California Legislative Information. California Penal Code 1202.4
Longer-Term Consequences
A Strike on Your Record
A felony DUI with injury that includes a great bodily injury finding qualifies as a strike under California’s Three Strikes law. Penal Code 1192.7(c)(8) lists any felony involving the personal infliction of great bodily injury as a serious felony. A single strike doubles the prison sentence for any future felony. A second strike can produce 25 years to life. The consequence applies even where the underlying DUI would otherwise look like a mid-level offense.
Crossing the Canadian Border
Canada treats impaired driving as serious criminality, and a single conviction can make you inadmissible at the border. Border officers can deny entry regardless of how old the conviction is. Travelers with a DUI record can apply for a Temporary Resident Permit for short-term entry or seek permanent criminal rehabilitation once five years have passed since completing every part of the sentence, including probation, fines, and license suspension.
Employment and Professional Licensing
A felony DUI with injury appears on background checks and can disqualify applicants from jobs requiring a clean driving record, security clearance, or a professional license. California restricts employers from asking about arrests that did not lead to convictions and from considering convictions that have been judicially dismissed, but an active felony conviction remains fully reportable. Licensed professionals in fields like nursing, law, real estate, and commercial driving can face disciplinary proceedings up to suspension or revocation of their credentials, entirely separate from the criminal case.
