SAN DIEGO, CA - Drivers facing DUI charges in California increasingly encounter Ignition Interlock Device requirements as part of their legal proceedings and license restoration process. San Diego DUI attorney Anna R. Yum of the Law Offices of Anna R. Yum (https://www.annayumlaw.com/how-does-an-ignition-interlock-device-work/) explains how these devices function and when they may be required following a DUI arrest.
According to San Diego DUI attorney Anna R. Yum, an Ignition Interlock Device is essentially a portable breathalyzer installed directly into a vehicle that prevents the car from starting if alcohol is detected. Before starting the vehicle, drivers must provide a breath sample, and if the device detects alcohol above a preset limit of approximately 0.02% BAC, the vehicle will not start. "The IID is designed to be tamper-resistant and must be professionally installed by state-certified technicians," explains Yum.
San Diego DUI attorney Anna R. Yum notes that drivers may be required to install an IID in two primary situations under California law. First, individuals whose licenses have been suspended by the California Department of Motor Vehicles may be eligible for a restricted license that requires IID installation, allowing them to drive for work, school, or family obligations. Second, courts, including the downtown courthouse on Broadway, the South Bay courthouse in Chula Vista, the East County facility in El Cajon, or the North County Regional Center in Vista may order IID installation as a condition of a DUI conviction.
The duration of IID requirements varies based on prior convictions and specific circumstances. For a first-time DUI offense where the blood alcohol level was 0.15% or greater, courts can impose an IID requirement for up to six months. "If you have a prior DUI conviction within the last ten years, your current case would be considered a second DUI offense, and the IID requirement increases significantly, potentially extending up to one year," notes Attorney Yum.
The device requires drivers to provide breath samples before starting their vehicle and during random intervals while driving in what are called rolling retests. Yum emphasizes that the device may prompt drivers to provide additional breath samples while continuing to drive, requiring them to safely pull over and blow into the breathalyzer again. These rolling retests serve an important safety function by ensuring drivers haven't consumed alcohol after starting the vehicle.
If a driver fails a rolling retest while driving, the device will not shut off the car but will trigger the vehicle's horn to honk and lights to flash until the vehicle is turned off. "The failed test is immediately logged in the device's memory, creating a permanent record of the violation," advises Yum. These logs are regularly downloaded during mandatory service appointments and reported to the monitoring authority, which typically includes the court, the California DMV, and possibly the driver's probation officer.
Local law enforcement agencies throughout the region, including police departments in Oceanside, Carlsbad, Escondido, National City, La Mesa, and other municipalities, work closely with the courts and the District Attorney's office to monitor IID compliance. This coordinated approach means violations are quickly detected and reported to the appropriate authorities. Repeated failures can lead to extended IID usage, additional court penalties, probation violations, and potential additional charges.
Beyond legal implications, IID requirements carry high financial costs. "Initial installation typically costs between $100 and $150, with regular maintenance appointments required every 60 days that come with their own fees," explains Attorney Yum. Ongoing daily or monthly rental fees can range from several dollars per day to monthly fees exceeding $100, and these costs can add up quickly over the required installation period.
Throughout the San Diego region, from Oceanside and Carlsbad in the north to Chula Vista and Imperial Beach in the south, and from coastal communities like La Jolla and Del Mar to inland areas like Santee, Poway, and Ramona, several state-certified providers offer installation services at various locations. Many drivers apply for restricted licenses through local DMV offices in Clairemont, El Cajon, Chula Vista, or Oceanside to maintain their ability to commute to work while their DUI case is pending.
While IID requirements may seem burdensome, they can provide an opportunity to retain limited driving privileges and demonstrate commitment to safe driving. For individuals facing DUI charges in Southern California, understanding IID requirements and navigating the legal process with experienced counsel can make a significant difference.
