Learn how it is proven, penalties, and defenses. Topics: DUI, Vehicle Code California [Vehicle Code 23152(g)](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?sectionNum=23152.&lawCode=VEH) covers the situation neither the alcohol-only nor the drugs-only DUI statute is built for: a driver whose alcohol consumption and drug use combine to impair them, even when neither substance alone would clear the bar. This charge shows up often in cases involving a moderate amount of alcohol, sometimes under the 0.08% threshold, mixed with a prescription medication, cannabis, or an over-the-counter drug with sedating effects. Individually, prosecutors might not be able to prove impairment from either substance. Together, the argument is that the combination pushed the driver over the line. ## What Does VC 23152(g) Actually Say? > It is unlawful for a person who is under the combined influence of any alcoholic beverage and drug to drive a vehicle. The statute does not require the alcohol or the drug to independently meet the standard for a 23152(a) or 23152(f) charge. It asks whether the two together impaired the driver's ability to drive with the caution of a sober, unimpaired person. ## Elements Prosecutors Must Prove To convict you under VC 23152(g), the prosecution must prove, beyond a reasonable doubt: - You drove a motor vehicle - You were under the combined influence of an alcoholic beverage and a drug at the time you drove, and that combination impaired your ability to drive safely ## Why Prosecutors Charge This Instead of, or Alongside, 23152(a) and (f) A combined-influence charge gives prosecutors a fallback. If your BAC came back at 0.06% and a blood test also showed a sedating antihistamine or a small amount of THC, neither number alone might support a straightforward alcohol or drug DUI charge. VC 23152(g) lets the prosecution argue the combined effect, supported by an expert's testimony about how the substances interact, still amounts to impairment. The [California Driver Handbook](https://www.dmv.ca.gov/portal/handbook/california-driver-handbook/alcohol-and-drugs/) is direct about this: it is illegal to drive while under the influence of alcohol or any drug that affects your ability to drive safely, and mixing substances that individually might seem manageable can still add up to unsafe driving. ## Is This a Misdemeanor or a Felony? A first VC 23152(g) offense is generally charged as a misdemeanor under the same sentencing structure as a standard DUI. It can become a felony under the same circumstances that elevate any DUI charge: a fourth qualifying conviction within 10 years under VC 23550, a prior felony DUI under VC 23550.5, or an accident causing injury, which falls under VC 23153. ## Penalties for a VC 23152(g) Conviction The baseline penalty structure mirrors a standard first-offense DUI: 3 to 5 years of informal probation, up to 6 months in county jail, fines and assessments that commonly reach $2,000 or more, mandatory DUI school, and license consequences handled through a separate DMV Administrative Per Se proceeding. Penalties escalate for each qualifying prior conviction within the 10-year lookback period. ## Common Defenses to a VC 23152(g) Charge Combined-influence cases require the prosecution to connect two substances to a single impairment theory, which creates specific openings for the defense: - **No expert link between the substances and impairment**: The prosecution needs a toxicologist or similarly qualified expert to explain how the specific combination affected you. Without that testimony, the theory falls apart. - **Prescription or over-the-counter use as directed**: Using medication as prescribed, combined with a small amount of alcohol, does not automatically prove impairment. - **Field sobriety and DRE evidence problems**: The same challenges available in single-substance cases, unreliable test conditions, medical explanations for poor performance, and subjective DRE conclusions, apply here. - **Rising blood alcohol**: If the alcohol component of the case relies on a delayed test, your BAC may have been lower, or even negligible, at the time you were actually driving. - **Unlawful stop or arrest**: Standard Fourth Amendment challenges to the traffic stop and arrest apply. ## Related DUI Charges VC 23152(g) connects directly to the rest of California's DUI statute: - [**VC 23152(a): **](/penal-codes/vehicle-code-23152-a-driving-under-the-influence)[Driving while actually impaired by alcohol](/penal-codes/vehicle-code-23152-a-driving-under-the-influence) - **VC 23152(b): **Driving with a BAC of 0.08% or higher - [**VC 23152(f): **](/penal-codes/vc-23152-f--dui-of-drugs-duid)[Driving under the influence of drugs](/penal-codes/vc-23152-f--dui-of-drugs-duid) - [**VC 23550 / 23550.5: **](/penal-codes/vc-23550-23550-5-felony-dui-4th-offense-prior-felony-dui)[Felony DUI for a fourth offense or a prior felony DUI](/penal-codes/vc-23550-23550-5-felony-dui-4th-offense-prior-felony-dui) ## Frequently Asked Questions ### Can I be convicted under VC 23152(g) if my BAC was below 0.08%? Yes. This charge does not depend on hitting the 0.08% threshold. Prosecutors argue that alcohol combined with a drug, even at a BAC below the legal limit, impaired your driving. ### Does the drug have to be illegal for this charge to apply? No. Prescription medications and over-the-counter drugs count, the same as under VC 23152(f), as long as the combination with alcohol impaired your ability to drive. ### How do prosecutors prove the substances combined to cause impairment? Typically through toxicology results paired with expert testimony explaining how the specific substances interact, along with officer observations and field sobriety test performance. ### Can I be charged with 23152(g) and 23152(a) or (f) for the same incident? Prosecutors sometimes charge multiple DUI subsections for the same incident to cover different theories of the case. A conviction on multiple counts for a single incident still generally counts as one DUI for sentencing purposes. ### Will this charge affect my license the same way a standard DUI does? Yes. A VC 23152(g) conviction triggers the same DMV license suspension process that applies to any DUI conviction, separate from the criminal case. ## Facing a Combined DUI Charge in California? Combined-influence cases rest on an expert theory connecting two substances to one impairment claim. That theory can be attacked.
