or mechanic disables the IID when not in use by the sanctioned individual, or temporarily for servicing the vehicle. In some implementations, disabling by mechanics and others is either permitted or authorisation easily obtained, but some jurisdictions restrict or deny authorisation. (Such restrictions on mechanics can be problematic, for example, if limited to designated "licensed mechanics" or as applied to routine repair procedures requiring operation of the ignition and starter systems.) Some jurisdictions criminalize such temporary bypass of IIDs. Violations Violations can occur from a driver not having reached the "zero tolerance" level, but can also occur from use by other drivers within legal limits, or from test anomalies. In some states, anomalies are routinely discounted, for example as not consistent with patterns of BAC levels or at levels incompatible with life (e.g., significant mouth alcohol - if read as BAC would mean the patient is dead). In some states, "fail" readings inconsistent with actual alcohol use can be cleared by a routine process, but other states automatically deem these "fail" readings as violations. Individual state provisions Alaska "DUI Offenders may be required to obtain an Ignition Interlock Device (IID)." Arizona Arizona mandates a minimum of six months for all DUI offenses, including those not involving alcohol. All IIDs must be installed by an approved company, and must be equipped with a camera, GPS and real-time reporting capabilities. California As of July 1, 2010, California implemented a pilot project for DUI sentencing, as a pilot program involving four counties under AB 91: Alameda, Los Angeles, Sacramento, and Tulare. Under the pilot project, if driving on a suspended license due to a DUI conviction, legally the court must impose an ignition interlock device requirement for up to a maximum of three years from the date of conviction. As of July 1, 2010, interlocks are required upon a DUI conviction in the four counties. In the four counties under the AB 91 pilot program, all drivers convicted of a DUI offense are required to install IIDs in their vehicles as a condition to receive restricted driving privileges. First offenders convicted of drunk driving are required to install an ignition interlock device in their car for a period of five months and second offenders for a period of one year. Previously, this requirement was only required for third offenders and permitted for second offenders, and then for a three-year period. The California DMV
