What Must the Prosecutor Prove for a VC 23153 Conviction?

To secure a conviction for a DUI causing injury, the prosecution must prove four separate legal elements beyond a reasonable doubt. Merely demonstrating that you were driving above the legal blood alcohol limit is insufficient.

Driving: The defendant operated and moved a motor vehicle.
Intoxication: The defendant was driving under the influence of alcohol or drugs (VC 23153(a)), or had a Blood Alcohol Concentration (BAC) of 0.08% or higher (VC 23153(b)).
An Illegal Act or Neglect of Duty: Besides driving under the influence, the defendant also committed another traffic violation, such as speeding or running a red light, or acted with overall negligence.
Causation of Injury: The defendant's illegal act or negligent behavior was the direct cause of physical bodily injury to another person.

Penalties Under California Vehicle Code 23153

The severity of consequences varies considerably depending on how the offense is filed and if aggravating circumstances are present.

Misdemeanor VC 23153

If filed as a misdemeanor (typically for first-time offenses involving relatively minor injuries), the penalties generally include:

Incarceration: 5 days to 1 year in county jail.
Fines: $390 to $5,000 (which can easily exceed $10,000 after mandatory court penalty assessments are added).
Probation: 3 to 5 years of informal (summary) probation.
DUI School: Mandatory enrollment in a California DUI education program lasting 3, 9, 18, or 30 months.
Driver's License: 1 to 3-year suspension by the DMV (an Ignition Interlock Device may be required to regain driving privileges).
Restitution: Mandatory full compensation to the injured parties for medical bills, property damage, and lost wages.

Felony VC 23153

When filed as a felony—which is typical in cases of severe injuries, multiple victims, or prior DUI convictions—the penalties become significantly more severe.

Incarceration: 2, 3, or 4 years in California State Prison.
Fines: $1,015 to $5,000 plus penalty assessments.
Probation: Formal felony probation.
Driver's License: 5-year revocation of driving privileges, along with a potential Habitual Traffic Offender (HTO) designation.
DUI School: 18 to 30 months of mandatory program attendance.

Sentence Enhancements (The Multipliers)

When a felony DUI involves specific aggravating factors, judges must apply consecutive sentences that stack additional prison time on top of the base charge:

Great Bodily Injury (GBI) under PC 12022.7: If a victim suffers a significant physical injury (like broken bones, severe lacerations, or brain trauma), this adds 3 to 6 additional years in state prison. It also triggers a permanent "Strike" on your record under California's Three Strikes Law.
Multiple Victim Enhancement (VC 23558): You face an additional 1 year in state prison for each extra person injured in the accident (capped at a maximum of 3 extra years).
Prior DUI Convictions: Any DUI or wet reckless conviction within the past 10 years results in strict mandatory minimum penalties and causes future offenses to automatically be prosecuted as felonies.

Note on Restitution: Criminal court restitution orders for economic losses are separate from civil lawsuits. Crucially, restitution debts arising from a DUI causing injury cannot be discharged or wiped out in bankruptcy.

Real-World Example Case

The Scenario: Liam is driving home from a restaurant in Los Angeles and makes an illegal left turn at an intersection, colliding with an oncoming sedan. The driver of the other vehicle sustains a fractured wrist and severe bruising.

The Testing: Law enforcement arrives, notes a smell of alcohol, and administers a chemical test within two hours. Liam registers a 0.09% BAC.

The Outcome: Because Liam committed a separate traffic infraction (the illegal left turn) while over the 0.08% limit and caused physical injury to another person, he is charged with a felony under Vehicle Code 23153(b). Even though the victim's injuries are not life-threatening, Liam faces state prison time, mandatory victim restitution, and a long-term driver's license revocation unless a skilled DUI attorney can challenge the chemical test or the fault of the accident.

Common Legal Defense Strategies

DUI causing injury cases are complex and typically depend on accident data and forensic toxicology. Skilled defense attorneys counter the state's case through several key tactics:

Challenging Fault and Causation: The prosecution needs to demonstrate that your illegal maneuver was the direct cause of the injury. If the other driver ran a stop sign or if the accident was unavoidable because of road conditions, then the causation element is not satisfied.
Contesting the Degree of Injury: For prosecutors to claim a felony or apply a Great Bodily Injury (GBI) enhancement, the harm must be substantial. Defenses can prove that minor bumps, scratches, or subjective pain do not meet the statutory requirements for enhanced charges.
Inaccurate Chemical BAC Testing: Breathalyzers and blood analysis must adhere to strict California Title 17 protocols. Your defense can file a Blood Split Motion to have an independent laboratory re-test the blood sample for improper preservation, contamination, or fermentation.
Rising Blood Alcohol: Alcohol absorption takes time. An expert toxicologist could show that your BAC was under 0.08% at the moment of driving but increased naturally during the delay before the police conducted the chemical test.

Frequently Asked Questions (FAQs)

Is a DUI causing injury automatically charged as a felony?

No. In California, Vehicle Code 23153 is classified as a "wobbler" offense, allowing prosecutors to charge it as either a misdemeanor or a felony. The decision depends on factors like the extent of the victim's injuries, the driver's behavior behind the wheel, and their prior criminal record.

What qualifies as a "bodily injury" under VC 23153?

A bodily injury involves more than minor discomfort but does not have to be severe or life-threatening. Courts consider lacerations, broken bones, severe bruising, or concussions as qualifying bodily injuries.

Can a DUI causing injury count as a "strike" under the Three Strikes Law?

A standard VC 23153 conviction is not a strike. However, if the prosecution proves that the victim suffered "Great Bodily Injury" (under PC 12022.7), the offense becomes a violent felony and counts as a permanent strike on your record.

What is the 3-Hour Rebuttable Presumption rule?

Under California law, if a chemical breath or blood test is administered within three hours of driving and indicates a BAC of 0.08% or more, the court automatically presumes you were over the legal limit while driving. However, a defense attorney can challenge this by demonstrating that your BAC was still increasing at the time.

Can I negotiate a VC 23153 charge down to a lesser offense?

Yes. Depending on the weaknesses in the prosecution's evidence, an attorney may successfully negotiate the charge down to a standard misdemeanor DUI (VC 23152), a "reckless driving causing injury" (VC 23104), or a "Wet Reckless" (VC 23103.5).

Do I have the right to refuse a chemical test after an injury accident?

Under California's Implied Consent law (VC 23612), you must submit to a blood or breath test after a lawful DUI arrest. Refusing a chemical test will trigger a mandatory 1-year license revocation with no option for a restricted license, and prosecutors can use the refusal as evidence of guilt in court.
