DUI cases often involve scientific evidence, police observations, and complex constitutional issues.

His experience allows him to uncover issues that may not be apparent to someone unfamiliar with California DUI litigation.
Los Angeles County operates one of the largest and busiest court systems in the United States. DUI cases may be assigned to courthouses such as the Clara Shortridge Foltz Criminal Justice Center, Airport Courthouse, Van Nuys Courthouse, Pasadena Courthouse, Torrance Courthouse, Long Beach Courthouse, and numerous other judicial districts.
Because procedures and practices can vary significantly between courthouses, familiarity with local court operations can make a meaningful difference. Liberty DUI & Criminal Defense understands how Los Angeles County prosecutors handle DUI filings and enforce California DUI laws, and how local judges approach sentencing, diversion requests, evidentiary challenges, and probation terms.
A DUI arrest does not automatically result in a conviction. Many cases involve questionable evidence, including:
Our firm thoroughly examines every aspect of the arrest to determine whether evidence can be excluded, reduced, or challenged at trial.
Vehicle Code Section 23152(a) makes it unlawful to operate a motor vehicle while under the influence of alcohol or drugs. Prosecutors do not need to prove a specific blood alcohol concentration under this subsection. Instead, they must show that your physical or mental abilities were impaired to a degree that prevented you from driving with the caution expected of a sober person.
Vehicle Code Section 23152(b) prohibits driving with a blood alcohol concentration (BAC) of 0.08% or greater. Even when chemical testing indicates a BAC above the legal limit, there may be valid defenses involving testing procedures, equipment calibration, rising blood alcohol levels, or laboratory errors.
A first DUI conviction in Los Angeles County may result in:
The exact outcome depends on the circumstances of the arrest, the defendant’s criminal history, and the strength of the evidence.
Certain DUI offenses can be charged as felonies under California law. Examples include:
Felony Los Angeles DUI convictions may expose defendants to state prison sentences, lengthy license suspensions, and significant collateral consequences. We aggressively challenge felony allegations and seek reductions whenever possible.
Commercial drivers face particularly harsh consequences after an arrest for driving under the influence. Under California law, a CDL holder can lose commercial driving privileges for at least one year following a DUI conviction. For truck drivers, delivery operators, and transportation professionals, protecting a commercial license is often just as important as defending the criminal case itself.
Depending on the circumstances, your DUI case may involve:
Our firm represents clients throughout every stage of the court process and DMV proceedings.
Unlike smaller counties, Los Angeles County does not process all DUI matters through a single courthouse. Instead, cases are assigned based on the location of the arrest.

Even a first DUI in Los Angeles can lead to license suspension, probation, fines, increased insurance premiums, and criminal charges. An attorney may identify legal defenses, negotiate reduced charges, or challenge evidence that could otherwise go unexamined.
Not necessarily. Many drivers qualify for restricted driving privileges or Ignition Interlock Device programs, depending on the circumstances of the case and DMV eligibility requirements.
In most cases, you have only 10 days from the date of arrest to request a DMV Administrative Per Se hearing. Failing to act promptly may result in an automatic license suspension.
Sobriety checkpoints are generally permitted under California law. However, law enforcement agencies must comply with constitutional requirements regarding planning, operation, safety measures, and vehicle selection procedures. Failure to follow these requirements may provide grounds for a legal challenge.
California’s implied consent laws require drivers lawfully arrested for drunk driving to submit to a chemical test. Refusal may result in enhanced license suspension periods and additional penalties. However, the legality of the arrest itself may still be challenged.
Yes. Blood testing is not immune to error. Issues involving contamination, fermentation, chain-of-custody problems, improper storage, and laboratory mistakes can affect the reliability of the results.
Drug-related DUI cases often involve prescription medications, marijuana, or other controlled substances. Unlike alcohol-related cases, there is frequently no universally accepted numerical threshold for impairment, creating opportunities to challenge the prosecution’s conclusions.
For sentencing enhancement purposes, a DUI generally remains a prior offense for ten years under California law. Future DUI arrests during that period may be prosecuted as repeat offenses.
Many individuals become eligible for relief under California Penal Code § 1203.4 after completing probation and satisfying all court requirements. An expungement can improve employment opportunities and help mitigate the long-term impact of a conviction.
Immediately. Surveillance footage, witness statements, body camera recordings, dispatch logs, and other evidence can disappear quickly. Early intervention also allows your attorney to preserve your DMV hearing rights and begin building a defense before critical deadlines expire.
