SAN DIEGO, CA - A second DUI arrest within ten years carries significantly harsher consequences under California law, including mandatory jail time, extended license suspension, and substantial fines that can affect every aspect of a person's life. San Diego DUI defense attorney Anna R. Yum of the Law Offices of Anna R. Yum (https://www.annayumlaw.com/second-drunk-driving-offense/) is providing guidance on what individuals charged with a repeat DUI offense can expect and how an experienced defense strategy may help protect their future.
According to San Diego DUI defense attorney Anna R. Yum, California Vehicle Code Section 23540 imposes mandatory minimum penalties for a second DUI conviction that are roughly double those of a first offense. Under the statute, individuals face 90 days to one year in county jail, fines that reach between $1,800 and $2,800 after penalty assessments, and enrollment in an 18-month or 30-month DUI education program. "A second DUI charge carries serious mandatory minimums, but that does not mean the outcome is predetermined," explains Yum. "Every case has details that deserve thorough examination."
San Diego DUI defense attorney Anna R. Yum notes that the consequences extend well beyond the courtroom. The California DMV imposes a separate one-year administrative per se suspension for individuals who test at or above 0.08% BAC, and those who fail to request a hearing within ten days of arrest forfeit the opportunity to challenge that suspension. Without the installation of an Ignition Interlock Device, a second DUI conviction results in a full two-year suspension with no driving privileges.
Attorney Yum emphasizes that if probation is granted, the court may reduce the custody requirement to a minimum of 96 hours, served in two continuous 48-hour periods, or at least ten days, depending on the circumstances. Judges also weigh aggravating factors such as a significantly elevated blood alcohol concentration, chemical test refusal, excessive speed, or the presence of a minor in the vehicle. "The difference between a minimum sentence and the maximum often comes down to the strength of the defense presented," she adds.
Several defense strategies may apply in second DUI cases. Challenging the legality of the initial traffic stop can result in the suppression of all evidence gathered afterward if the officer lacked reasonable suspicion. Field sobriety tests are subject to challenge on the grounds of improper administration, medical conditions, or environmental factors. Chemical test results may also be contested when Title 17 of the California Code of Regulations protocols for calibration, maintenance, or observation periods were not followed.
The rising blood alcohol defense is another approach that may benefit individuals who were stopped shortly after their last drink. Blood alcohol concentration can continue to rise for 30 to 90 minutes after consumption, meaning a driver's BAC may have been below the legal limit while behind the wheel but exceeded 0.08% by the time testing occurred. "Understanding the science behind chemical testing is essential to building an effective defense," observes Yum. "Procedural errors and timing issues are more common than most people realize."
The Law Offices of Anna R. Yum handles DUI cases throughout San Diego County, including matters at the San Diego Hall of Justice, the South County Regional Center in Chula Vista, the North County Regional Center in Vista, and the East County Regional Center in El Cajon. As a former prosecutor with the Riverside County District Attorney's Office, Yum brings insight into how the prosecution builds its case and what strategies are most effective in challenging the evidence.
In some instances, prosecutors may agree to reduce a second DUI to a wet reckless charge under Vehicle Code Section 23103.5, which carries reduced jail time, lower fines, and a shorter probation period. This outcome is more likely when the evidence presents weaknesses such as a borderline BAC reading or procedural issues with the traffic stop or chemical testing. For those facing a second DUI charge in San Diego, consulting with an experienced defense attorney may help identify the most effective path forward.
