Starting January 1, 2019, a new law will require those convicted of Vehicle Code Section 23152 (DUI-Driving Under the Influence) in California to install an IGNITION INTERLOCK DEVICE (IID). While proponents cite studies that IIDs reduce DUI incidents, this is certainly not good news for those already saddled with expensive fines, programs and other punishments.

IIDs are small breathalyzers that are attached to a vehicle's steering column, requiring a driver to provide a breath sample before the vehicle can start: if the sample contains alcohol, the vehicle will not start. As the person drives their vehicle, the breathalyzer device requires that the driver periodically blow into the device during the trip.

Who Will Be Required to Install an IID Under the Ignition Interlock Device Law in California?

Ignition Interlock Device installation will be mandatory in DUI cases and will require installation for a six month period. An offender may choose a six-month IID requirement with full driving privileges, or a one-year restricted license that would only allow them to drive to and from work if they also participate in a treatment program

  • First DUI Offense: Six Months
  • Second DUI offense: One year
  • Third DUI offense: Two years
  • Fourth or subsequent DUI offense: Three years

As with any breath testing device, these IIDs are not infallible. If required to install a device, always err on the side of caution: no alcohol of any kind, including mouthwashes and other substances that may trigger a false reading. 

This is only a brief summary of the 2019 changes to California's IID laws. For more information, don't hesitate to contact the Law Offices of David Welch
