California Ignition Interlock Guidelines

The California interlock device laws differ from many other states, which is why it is important to fully understand your state-specific guidelines. In California, if you are convicted of a DUI your penalties will differ on a case by case basis, but there are general protocols that are common. Usual penalties in California are license suspension, mandatory alcohol program and fines.

In July of 2010, an ignition interlock device pilot program was put into place in California. This pilot program requires all people convicted of a DUI in Alameda, Tulare, Los Angeles, or Sacramento county to have an ignition interlock device installed in their motor vehicle even if it is their first DUI offense. If you are a repeat offender (second, third or fourth time), an interlock device is required in every county in California.

Starting in 2019, the pilot program is going to expand to every county in California. In January of 2019, every repeat offender convicted of a DUI in California will be required to install an ignition interlock device in their vehicle. In addition, first time offenders convicted anywhere in California who have caused an injury will now be required to install an interlock device in their vehicle. 

According to California State Law, attempting to remove your ignition interlock device is considered noncompliance and failure to take a rolling retest can end in a system lockout. In addition, if your breath alcohol level is above the California limit, your car will not start and could end in a lockout. California ignition interlock program participants cannot drive a car that doesn’t have a working ignition interlock device in it. And if you are traveling out of California you still need to comply with the rules of the California interlock program.

California DUI Penalties

Each county in California has slightly different DUI penalties. Because of this, it is important to research and understand the penalties of the county you were convicted in. In certain counties, there are mandatory penalties that are non negotiable. For example, Riverside and Ventura Counties are known to have some of the strictest rules surrounding DUI convictions. In most DUI cases tried in Riverside or Ventura county, jail time is mandated even on a first offense. To learn more about county specific DUI information, click your city below!
