Being arrested for a felony DUI in Los Angeles is frightening because driving under the influence can quickly turn into serious criminal penalties that affect your freedom, job, and driver’s license. A felony DUI is much more severe than a standard drunk driving case and may lead to state prison and long-term license suspension.
William S. Kroger Criminal Defense Attorney at Law helps clients fight DUI charges with a strong DUI defense and careful attention to every detail in the legal process. Our Los Angeles felony DUI attorney builds aggressive defense strategies to protect your freedom, record, and future from harsh penalties.
A felony DUI in Los Angeles is a driving under the influence case charged as a felony instead of a misdemeanor, usually because of prior DUI convictions or because someone was injured.
Felony DUI cases carry harsher criminal penalties, including possible state prison, longer driver’s license revocation, and formal felony probation. These cases move through Los Angeles County courts and require experienced criminal defense.
Under California VC 23152, it is illegal to drive while impaired by alcohol or drugs or to drive with a blood alcohol concentration of 0.08% or higher. Driving under the influence includes alcohol, drugs, or a combination of both.
Prosecutors use blood alcohol readings, breath tests, and chemical tests to measure blood/breath alcohol levels. California DUI laws apply throughout Southern California, including Orange and Los Angeles Counties.
Under California Vehicle Code § 23550 and California Vehicle Code § 23550.5, a DUI becomes a felony when a person has a fourth DUI within 10 years or has a prior felony DUI conviction. Repeat DUI cases are treated more severely in the criminal justice system.
The district attorney's office reviews prior convictions before filing charges. A deputy district attorney may decide to charge the case as a felony based on history.
Under California Vehicle Code § 23153, DUI causing injury can be filed as a misdemeanor or felony, making it a “wobbler” offense. The prosecution must show that impaired driving caused injury to another person. These cases often involve claims of gross negligence. Serious injury cases may lead to felony DUI charges and harsher punishment.

Felony DUI causing injury cases are complex and often involve strong evidence from law enforcement. Prosecutors in Los Angeles County must prove specific legal elements in criminal court case proceedings. These cases may also involve claims of vehicular manslaughter or vehicular homicide in extreme situations.
Under California Penal Code § 12022.7, prosecutors may add enhancements for great bodily injury. This enhancement increases jail time or exposure to state prison. It applies when the victim suffers significant physical harm. Enhancements can greatly increase criminal penalties.
A prior felony DUI conviction makes new DUI charges more serious. The criminal justice system treats repeat impaired driving as a major risk to public safety. Courts in Southern California criminal courts review prior records carefully.
California uses a 10-year lookback period to count prior DUI convictions. If you have multiple DUI cases within this time frame, penalties increase. The Los Angeles district attorney's office checks prior records before filing charges.
Repeat offenders may be labeled habitual traffic offenders. This status increases punishment and monitoring. License suspension periods may become much longer.
Felony DUI penalties are severe and can affect every part of your life. Courts in Los Angeles County may impose jail time, state prison, fines, and long-term driver’s license revocation. The criminal court case may also involve formal probation and strict conditions.
Base terms for felony DUI may include 16 months, 2 years, or 3 years in state prison. Enhancements can add more time. In some cases, a sentence may start in a county jail before transfer. Prison exposure is much greater than in standard DUI cases.
Felony DUI convictions include heavy fines and court costs. Additional assessments may apply. DUI school and alcohol education programs are often required.
Under California Vehicle Code § 13353.2, an administrative suspension occurs after arrest. This administrative suspension is separate from the criminal court process. Mandatory revocation periods may apply after conviction. The driver may receive an admin-per-se temporary driver's license using the DS367 form, but action must be taken promptly.
Courts may order formal felony probation instead of immediate state prison. Probation conditions can include DUI school, alcohol education, and regular reporting. Violating probation can result in additional jail time.
Certain factors make felony DUI cases more serious. Prosecutors use these facts to argue for stronger punishment. The Office of Traffic Safety supports strict enforcement of drunk driving laws.
Under California Vehicle Code § 23578, a high blood alcohol concentration is an aggravating factor. A very high blood alcohol level may increase penalties. Courts view high blood alcohol readings as more dangerous.
Under California Vehicle Code § 23612, the implied consent law requires drivers to submit to chemical tests after lawful arrest. Refusal can lead to a longer driver’s license suspension. Chemical testing includes breath tests and blood tests.
Under California Penal Code § 273a, driving under the influence with a child in the car may lead to child endangerment charges. This can add separate criminal penalties. It may also significantly increase jail time.

Felony DUI cases move through Los Angeles County courts and follow a structured court process. Each stage matters and requires careful preparation. An experienced trial attorney provides strong criminal trial defense at every step.
At arraignment, charges are formally read in court. The defendant enters a plea. The case begins in the Los Angeles County courts. The judge may also discuss bail and future court dates. This hearing is often the first time you stand before the court in your felony DUI case.
Pretrial motions may challenge probable cause, chemical testing procedures, or evidence collection under Title 17 of the California Code. These motions may limit what evidence is used at a jury trial. Your lawyer may ask the court to remove unfair or illegal evidence. Winning a motion can make the prosecutor’s case much weaker.
Some felony DUI cases resolve through plea negotiations. A plea agreement may reduce charges or avoid state prison. The defense and the prosecutor may discuss alternatives to prison, such as probation. A fair agreement can lower penalties and reduce long-term damage.
If no agreement is reached, the case proceeds to a jury trial. The prosecution must prove guilt beyond a reasonable doubt. The defense attorney questions witnesses and challenges the evidence in court. If there is a conviction, the judge decides the final sentence after hearing arguments from both sides.
The DMV takes action separate from the criminal court case. A driver’s license may face administrative suspension even before trial. Quick action protects driving privileges in West Los Angeles and beyond.
You must request a DMV hearing within 10 days of arrest. Missing this deadline results in automatic driver’s license suspension. A Los Angeles DUI lawyer can represent you at the DMV hearing.
Under California Vehicle Code § 23575.3, courts may require an ignition interlock device. An interlock device ignition system prevents the car from starting if alcohol is detected. Installation may allow limited driving during suspension.
A strong DUI defense focuses on legal errors and weak evidence. Criminal defense lawyers review every detail in DUI cases. An effective drunk driving defense can reduce or dismiss charges.
If officers lacked probable cause, the traffic stop may be illegal. Evidence gathered after an unlawful stop may be excluded. This means the prosecutor may not be allowed to use that evidence in court. Without that evidence, the DUI charges may be reduced or even dismissed.
Breath and blood tests must comply with Title 17 rules. Mistakes in chemical testing can affect blood alcohol concentration results. Machines must be properly maintained and tested for accuracy. If the rules are not followed, the test results may not be reliable.
In DUI-causing injury cases, prosecutors must prove that impaired driving caused the injury. Other factors may have contributed to the accident. For example, the other driver may have made a mistake that caused the crash. If the injury was not directly caused by the defendant, the felony DUI charge may not stand.
Rising BAC means the blood alcohol level increased after driving. This defense argues that the driver was below the legal limit at the time of driving. Alcohol takes time to absorb into the body after drinking. Because of this delay, the test result may not reflect the true blood alcohol level at the time of driving.
