Effective July 1, 2010, a new California law applicable in four counties requires those convicted of driving under the influence to install a breathing tube and ignition interlock device on their vehicles. 

The installation of this device, which prevents the vehicle from starting if alcohol is detected on the person's breath, will be required of all first-time and repeat offenders in the Counties of Alameda, Los Angeles, Sacramento and Tulare.

The cost to the DUI offender is estimated to be $125 for installation, $60 per month for maintenance and $45 for administration fees.  A low-income program, however, is available for those who cannot afford these fees.
