DUI Defense Attorney In Walnut Creek, California

DUI Charges Are Serious

At Law Offices of Andrew Quan, we understand that facing DUI (Driving Under the Influence) charges in California can be a daunting experience. With strict DUI laws and severe penalties, it is crucial to have a skilled and knowledgeable attorney by your side to protect your rights and future. Our firm focuses on DUI defense, utilizing in-depth legal experience and a comprehensive approach to address every aspect of your case.

Understanding California DUI Laws

California enforces some of the toughest DUI laws in the nation. Under California Vehicle Code 23152, it is illegal to drive:

  • With a Blood Alcohol Concentration (BAC) of 0.08% or higher for drivers 21 and over.
  • With a BAC of 0.04% or higher for commercial drivers.
  • With any detectable BAC for drivers under the age of 21.


DUI charges can result from alcohol, drugs, or a combination of both, and penalties may vary depending on whether it is a first offense or a repeat offense.

Potential Consequences of a DUI Conviction

A DUI conviction in California can result in significant penalties, including:

  • Fines and Court Costs: Convictions can result in costly fines, which may increase with subsequent offenses.
  • License Suspension: A DUI conviction typically includes a license suspension by both the court and the Department of Motor Vehicles (DMV).
  • Mandatory DUI Education Programs: Convictions often require participation in DUI education programs.
  • Jail Time: Jail sentences are common for DUI offenses, especially if there is an aggravating factor such as an accident or prior offenses.
  • Increased Insurance Costs: A DUI conviction can lead to higher auto insurance premiums.
  • Employment Consequences: A DUI on your record can impact current and future employment opportunities, especially in fields requiring a clean driving record.

Key DUI Defense Strategies & Why You should Choose Andrew Quan Law

At Law Offices of Andrew Quan, we take a personalized approach to each DUI case, exploring all possible defense strategies, such as:

  • Challenging the Traffic Stop: We assess the legality of the traffic stop to ensure your Fourth Amendment rights were not violated.
  • Questioning Field Sobriety Tests: Field sobriety tests are subjective and may not accurately reflect impairment.
  • Analyzing BAC Test Procedures: Faulty breathalyzer machines, improper calibration, or mishandling of blood samples can lead to inaccurate BAC results.
  • Medical Conditions: Certain medical conditions, like acid reflux or diabetes, can cause false positives on breath tests.

We understand the nuances of California DUI law and are dedicated to helping you navigate the legal system with confidence.
