  1. Older devices • Susceptible to: • Circumvention • Tampering by offenders • False positives – positive readings due to mouth alcohol or environmental sources

  2. Smart Start Handset Sample ACS WR3 Handset Sample current devices

  3. Guardian Interlock Draeger Interlock XT current devices

  4. Monitech Quicktest LifeSafer current devices

  5. How does it work? A driver must blow into the mouthpiece of the device The device checks the drivers breath for measurable alcohol If measurable alcohol is detected, the vehicle will not start Sober drivers will be able to operate the vehicles normally

  6. How does it work? BAC = 0 Ignition

  7. Pre-set level The pre-set level refers to the breath alcohol concentration at which the driver will be prevented from starting the vehicle. The pre-set level is determined by the state authority. In most jurisdictions this is about .02 and can vary up to .05. The interlock device is never set at .00 in order to prevent frequent lockouts due to “false positives”. A false positive is when insignificant amounts of alcohol that would not impair the driver are detected, such as from the alcohol in mouth wash, and the driver is still prevented from starting the vehicle. This is not unusual because even our own bodies can produce alcohol as a natural by-product when consuming certain foods.

  8. How does it work? Ignition BAC = 0 Warn BAC <= 0.02 Interlock BAC > 0.02
