The vast majority of DUI arrests in California result in misdemeanor charges. But under certain circumstances, a DUI is charged as a felony — and the consequences are dramatically more severe. If you are facing a felony DUI charge, you need an attorney with serious criminal trial experience, not just a traffic lawyer.
When Is a DUI Charged as a Felony?
California law provides four main circumstances under which a DUI is charged as a felony: (1) the DUI caused bodily injury to another person (Vehicle Code § 23153); (2) the current offense is a fourth DUI within 10 years; (3) the defendant has a prior felony DUI conviction; or (4) the defendant has a prior conviction for gross vehicular manslaughter while intoxicated (Penal Code § 191.5) or vehicular manslaughter while intoxicated (Penal Code § 192(c)). In injury cases, the prosecution must prove that the defendant's negligence — in addition to the impairment — caused the injury.
Felony DUI with Injury — VC § 23153
A felony DUI causing injury is charged under Vehicle Code § 23153. The penalties depend on the severity of the injuries and the defendant's prior record. For a first felony DUI with injury, the sentence ranges from 16 months to 3 years in state prison, plus an additional 3 to 6 years for each person who suffers great bodily injury. The defendant may also face civil liability to the injured parties. A conviction results in a habitual traffic offender designation and a revocation of the driver's license.
Fourth Offense DUI
A fourth DUI within 10 years is automatically charged as a felony under Vehicle Code § 23550. The mandatory minimum sentence is 180 days in county jail, and the court may impose up to 3 years in state prison. The DMV will revoke the driver's license for 4 years. The defendant is designated a habitual traffic offender, which carries additional penalties for any subsequent driving violations.
Gross Vehicular Manslaughter While Intoxicated
If a DUI results in the death of another person, the prosecution may charge gross vehicular manslaughter while intoxicated under Penal Code § 191.5(a). This is a felony carrying 4, 6, or 10 years in state prison. If the defendant had a prior DUI conviction and was warned of the Watson advisement — a standard warning given at sentencing that a future DUI causing death could be charged as murder — the prosecution may charge second-degree murder under Penal Code § 187 (the 'Watson murder' theory), which carries 15 years to life.
Penalties at a Glance
| Offense / Situation | Potential Penalty |
|---|---|
| Felony DUI with injury — first offense | 16 months to 3 years prison; +3–6 years per GBI victim |
| Fourth DUI within 10 years | 180 days minimum; up to 3 years prison; 4-year revocation |
| Gross vehicular manslaughter (PC § 191.5(a)) | 4, 6, or 10 years state prison |
| Watson murder (PC § 187) | 15 years to life |
Penalties shown are general ranges. Actual sentences depend on the specific facts of your case.
How Attorney Kade Defends These Cases
- —Challenge causation in injury cases — the prosecution must prove the defendant's negligence caused the injury
- —Attack the chemical test results to undermine the impairment element
- —Challenge the validity of prior convictions used to elevate the charge to a felony
- —Negotiate a reduction to misdemeanor DUI if the injury was minor and the evidence is weak
- —Present mitigating evidence at sentencing to minimize prison exposure
- —Challenge the Watson advisement in murder cases — was it properly given and understood?
- —Seek a split sentence or alternative sentencing to minimize actual custody time
Frequently Asked Questions
A DUI becomes a felony in California when: it is a fourth or subsequent DUI within 10 years; the driver has a prior felony DUI conviction; the DUI caused bodily injury or death to another person (Vehicle Code § 23153); or the driver has a prior conviction for gross vehicular manslaughter while intoxicated (Penal Code § 191.5).
A felony DUI causing great bodily injury (Vehicle Code § 23153 with a GBI enhancement under Penal Code § 12022.7) is a serious felony and counts as a strike under California's Three Strikes Law. A standard felony DUI without GBI is not automatically a strike, but a prior felony DUI conviction can elevate a subsequent DUI to a felony.
In some cases, yes. A felony DUI charged under Vehicle Code § 23153 (DUI causing injury) may be charged as a wobbler — meaning it can be filed as either a felony or a misdemeanor. An attorney may be able to negotiate a misdemeanor filing or, after sentencing, petition the court to reduce a felony to a misdemeanor under Penal Code § 17(b) if you successfully complete probation.
