Mandatory Ignition Interlock Device after DUI Convictions
The California State Assembly recently passed Assembly Bill 366 which would mandate the installation of Ignition Interlock Devices for all persons convicted of driving under the influence, including first-time offenders. An Ignition Interlock Device prevents a car from starting unless and until the driver blows into the device with no detectable amount of alcohol on his or her breath.
The devices' manufacturers would be required to adopt a specified fee schedule for the costs of the device, relative to and commensurate with, the convicted driver's income. Interestingly, the Ignition Interlock Device provider is responsible for absorbing the remaining costs not paid by the convicted driver.
The mandatory installation of an Ignition Interlock Device and its concomitant costs to even first-time DUI convictions is a hefty penalty that drivers should be aware of. If passed in the Senate, which should be expected, the law could go into effect as early as January of 2026.
