Is a DUI a Felony in California?

In California, most Driving Under the Influence (DUI) charges are misdemeanors. However, some situations can elevate a DUI to a felony, including repeat offenses and cases involving injury or death. This guide explains when a DUI becomes a felony in California, the penalties involved, and what factors can affect how these cases are charged.
When A DUI Becomes A Felony In California
A felony DUI in California is a drunk driving charge treated more seriously than a misdemeanor offense. While most DUI charges are misdemeanors, certain circumstances can expose a driver to much harsher penalties and long-term consequences.
A felony DUI conviction can lead to state prison time, higher fines, license revocation, and lasting effects on employment, professional licenses, and criminal background checks. Because of these risks, felony DUI cases are often prosecuted more aggressively than standard DUI offenses.
Understanding what factors can elevate a DUI charge is an important first step in protecting your rights and evaluating your legal options.
Fourth DUI Within Ten Years
If a driver receives a fourth DUI conviction within a ten-year period, the charge becomes a felony under California Vehicle Code § 23550. Prior convictions include standard DUI convictions, wet reckless pleas, and out-of-state convictions that would qualify as DUIs in California.
Prior Felony DUI Conviction
If a driver has any prior felony DUI conviction on record, any new DUI charge may be prosecuted as a felony regardless of whether the new incident caused injury or involved other aggravating factors.
DUI Causing Injury
When a driver under the influence causes an accident that results in bodily harm to another person, the charge may be filed as a felony under California Vehicle Code § 23153. This is a wobbler offense, meaning the prosecutor has discretion to file it as a misdemeanor or felony depending on the severity of the injury and the driver’s prior record.
DUI Causing Death
If a person dies as a result of a DUI, the driver may face charges under Penal Code § 191.5 for vehicular manslaughter while intoxicated or, in the most serious cases, second-degree murder under Penal Code § 187, known as a Watson murder charge.
Aggravating Factors
Certain factors do not automatically make a DUI a felony, but can influence how prosecutors charge the case and how severely a court sentences a conviction. These include an extremely high BAC, excessive speed, or having a minor passenger in the vehicle at the time of the offense.
PRACTICE AREAS
Overview of California DUI Laws
California DUI laws are strict and apply to both alcohol and drugs. It is illegal to drive if your ability to operate a vehicle safely is impaired.
For most drivers, a BAC of 0.08% or higher can result in a DUI charge. Lower limits apply to commercial drivers and drivers under 21. A DUI may escalate from a misdemeanor to a felony if serious harm or prior offenses are involved. This affects not just legal consequences but also personal and professional life.
Legal Consequences and Penalties
Felony DUI convictions in California carry much more serious penalties than misdemeanor DUI offenses. The specific consequences depend on factors such as prior convictions, whether anyone was injured, and the severity of the incident.
Felony DUI Without Injury — Fourth Offense or Prior Felony DUI
A felony conviction for a fourth DUI or a DUI following a prior felony DUI conviction carries a state prison sentence of 16 months, two years, or three years under VC § 23550. Additional consequences include:

- Four-year driver’s license revocation

Felony DUI Causing Injury
A felony conviction under VC § 23153 for DUI causing injury carries a state prison sentence of 16 months, two, three, or four years, with additional consecutive sentences of one to six years if the injury is classified as great bodily injury. Fines can reach $5,000 plus penalty assessments, and a license revocation of four to five years applies, depending on the circumstances.
Long-Term Consequences
A felony DUI conviction affects more than just the immediate sentence. It appears permanently on background checks, can lead to loss or suspension of professional licenses, prohibits firearm ownership, and may restrict international travel. Insurance rates typically increase significantly following a felony conviction.

Common Defense Strategies for Felony DUI
When facing a felony DUI charge, there are several approaches a California DUI attorney may use to challenge the case.
- Challenging test accuracy: Breath and blood tests are prone to errors from improper calibration, equipment maintenance issues, or sample handling problems. Results can also be affected by medical conditions such as GERD or diabetes, which can produce falsely elevated BAC readings.
- Questioning the traffic stop: If law enforcement lacked probable cause to make the stop, or if proper procedures were not followed during the stop and arrest, evidence gathered as a result may be challenged.
- Miranda rights violations: If an arresting officer failed to administer Miranda rights properly, statements made during the arrest may not be admissible in court.
- Challenging prior convictions: In cases where the felony charge is based on prior DUI convictions, those prior convictions can be challenged if they were obtained improperly or without adequate legal representation.
Moving Forward After a Felony DUI Arrest
The earlier a felony DUI case is reviewed, the more opportunities there may be to preserve evidence, identify witnesses, and evaluate potential legal issues involving the arrest or testing procedures. Waiting too long can make it harder to challenge certain aspects of the prosecution’s case.
