Felony DUI Defense in California
Most DUIs are misdemeanors. But certain factors transform a DUI into a felony — exposing you to state prison, lifetime gun ban, and severe collateral consequences.
The four paths to felony DUI
1. Fourth DUI in 10 years (VC 23550.5)
Three or more prior DUI convictions within the last 10 years (including wet reckless) automatically makes a new DUI a straight felony — not a wobbler.
2. Prior felony DUI (VC 23550.5)
Any prior felony DUI conviction makes any subsequent DUI a felony, regardless of timing.
3. DUI with great bodily injury (VC 23153)
If your DUI caused another person to suffer "great bodily injury" as defined in PC 12022.7 (significant or substantial injury, not necessarily permanent), the offense is charged as a wobbler that can be felony.
4. Vehicular manslaughter while intoxicated (PC 191.5)
If the DUI caused a death, charges escalate to gross vehicular manslaughter (4, 6, or 10 years) or even murder (Watson murder, PC 187) with a prior DUI conviction.
Felony DUI penalties
- State prison: 16 months, 2 years, or 3 years
- DUI with GBI: add 3-year enhancement (or 5 if multiple victims)
- License revocation: 4 years
- Lifetime firearm ban under federal law
- Habitual Traffic Offender designation (HTO)
- Significant fines and restitution
- Ignition Interlock Device (after license restoration)
Defense strategies
Challenge prior convictions
Old DUI priors can be invalid if there were Boykin/Tahl violations (failure to advise of rights) or constitutional defects. A successful challenge can reduce a 4th DUI back to a misdemeanor.
Causation defense in DUI with injury
The prosecution must prove your DUI caused the injury. If the other driver was at fault, a passenger was unbelted, or the injury arose from another cause, the felony charge falls.
Negotiating the GBI enhancement
The GBI enhancement (PC 12022.7) adds 3 years to any felony sentence. Negotiating its dismissal often turns a long sentence into a manageable one.
PC 17(b) reduction
For wobblers, file a 17(b) motion at sentencing or after probation completion to reduce the felony to a misdemeanor — restoring gun rights (in non-DV cases), professional license eligibility, and most civil rights.

Frequently Asked Questions
When is a DUI a felony in California?
A DUI is charged as a felony if: (1) it is your 4th DUI within 10 years, (2) you have any prior felony DUI conviction, (3) the DUI caused great bodily injury (PC 12022.7) or death (vehicular manslaughter PC 191.5), or (4) any DUI involving prior strike enhancements.
What is the sentence for felony DUI in California?
State prison sentence of 16 months, 2 years, or 3 years (low/mid/high terms). DUI with great bodily injury can carry 2, 3, or 4 years plus a 3-year GBI enhancement. Vehicular manslaughter while intoxicated carries 4–10 years (or longer).
Can a felony DUI be reduced to a misdemeanor?
Yes, in some cases. Under PC 17(b), a felony "wobbler" can be reduced to a misdemeanor at sentencing or after probation. Felony DUI with injury is a wobbler; a 4th DUI in 10 years is straight felony. PC 17(b) reduction restores most civil rights.
Will a felony DUI affect my immigration status?
Often yes. A simple misdemeanor DUI is generally not a deportable offense, but felony DUI with injury can be classified as a "crime involving moral turpitude" or aggravated felony. Non-citizens facing felony DUI charges should consult both criminal defense and immigration counsel immediately.
