A DUI Accident With Injuries in California Is a Different Kind of Charge

When a DUI accident injures someone else, the charge shifts from a misdemeanor to a felony — and the consequences shift with it. State prison exposure replaces county jail. Multiple victims mean multiple counts. Great bodily injury enhancements stack consecutive sentences on top of the base offense. At the Law Office of Nic Cocis, we defend DUI cases involving injury in Murrieta and Southwest Riverside County with the seriousness the felony charge demands.

How California Charges DUI Accidents With Injuries

Vehicle Code § 23153 — The Injury DUI Statute

California Vehicle Code § 23153 applies when a person drives under the influence, commits an act forbidden by law or neglects a duty imposed by law while driving, and that act or neglect causes bodily injury to another person. Three elements must be proven: impairment, an unlawful act or negligence, and causation of injury. Each is contestable.

The base sentence for a first-offense § 23153 conviction is 16 months, two, or three years in state prison, or — in the court’s discretion — up to one year in county jail with formal probation. The prison exposure increases significantly with enhancements.

Great bodily injury — Penal Code § 12022.7.

A great bodily injury (GBI) enhancement adds three to six years consecutive to the base sentence. GBI means significant or substantial physical injury — broken bones, lacerations requiring significant medical intervention, internal injuries. Not every injury from a DUI accident qualifies, and the severity determination can be contested.

Multiple victim enhancement — Vehicle Code § 23558.

Each additional person injured beyond the first adds one year, consecutive, to the sentence. A DUI accident with three injured occupants of another vehicle can result in the base sentence plus two additional consecutive years before any GBI enhancement is even considered.

Prior DUI convictions.

A prior DUI conviction within ten years elevates the sentencing range significantly. A second or subsequent § 23153 offense within ten years carries two, four, or six years in state prison as the base range.

The Causation Element: Where Defense Often Lives

The prosecution must prove that the defendant’s driving caused the injury — not just that an accident occurred while the defendant was impaired. In multi-vehicle accidents, the cause of the collision may be genuinely contested. A driver who was impaired but was rear-ended presents a different causation picture than a driver who ran a red light. An impaired driver who had the green light when another driver turned into their path may have a valid causation defense.

Accident reconstruction evidence, traffic signal data, physical evidence from the scene, and witness accounts all bear on the causation question. We retain accident reconstruction experts in § 23153 cases where causation is contested.

How We Defend DUI Injury Cases

The defense in a § 23153 case is built on three levels: the impairment evidence, the causation theory, and the injury characterization.

Impairment.

The same chemical testing and field sobriety test challenges available in any DUI apply here — with higher stakes. A BAC just over the limit that’s contaminated by testing procedure problems is worth challenging even more aggressively when the charge is a felony rather than a misdemeanor.

Causation.

We reconstruct the accident independently and examine whether the defendant’s driving was the proximate cause of the injuries, or whether another party’s conduct was an intervening or contributing cause.

Injury characterization.

GBI enhancements depend on the injury meeting the “significant or substantial” standard. Not every injury from a vehicle accident meets that standard. Medical records, treatment records, and the actual severity of the injury are all examined against the legal definition.

01

Accident Reconstruction

We retain an independent accident reconstructionist to analyze the physical evidence and produce an opinion on causation that doesn't rely solely on the prosecution's investigation.

Medical Record Review

Every claimed injury is documented against the GBI standard. Injuries that don't meet the threshold shouldn't support a GBI enhancement, and challenging enhancement allegations directly affects the sentencing range.

Chemical Testing Analysis

The impairment evidence is examined with the same scrutiny as any DUI case. In a felony prosecution, this analysis is more consequential.

Negotiation and Trial

In § 23153 cases, the difference between the prosecution's initial charge and a negotiated resolution can be years. We enter those negotiations knowing the evidence and using it — not hoping the DA will be reasonable.

Frequently Asked Questions

Yes — but the prosecution still has to prove causation. If another driver’s negligence was the primary or sole cause of the collision, the “neglect of duty” element of § 23153 is harder to establish. Your impairment is relevant to sentencing and to any civil liability, but it doesn’t automatically satisfy the causation element of the criminal charge if you weren’t the proximate cause of the accident. This is a technically defensible position that we analyze fully in any case where the facts support it.

Consent is not a defense to § 23153. An injured passenger — regardless of whether they knew you had been drinking — is still a "person injured" for purposes of the statute. The charge applies when any person other than the driver is injured as a result of the DUI driving. A passenger who willingly got in the car does not waive the protection of the statute. Their contributory decision may affect civil liability but it doesn't affect the criminal charge.

Cases without significant disputes often resolve within six months to a year through plea negotiations. Cases where causation is genuinely contested, where the BAC evidence has significant challenges, or where GBI enhancements are disputed may require more time for expert analysis and motion practice before a realistic resolution can be evaluated. Cases that go to trial add additional time. We keep clients informed at every stage so that timeline expectations are realistic throughout.
