A handheld breathalyzer is a device used to measure blood alcohol content (BAC) from a breath sample. Handheld breathalyzers come in a variety of models that have either semiconductor-based sensing or fuel cell technologies. Handheld breathalyzers are used mainly for voluntary testing purposes and are often carried in purses, briefcases or vehicles by individuals wanting to ensure that they are not over the BAC limit before driving.

Ignition Interlock devices work in the same manner, but are installed on the dashboard of a motor vehicle. The driver the vehicle must provide a breath sample by exhaling into the device before the vehicle’s engine can be started. The device may prompt the driver to provide additional samples after the car is started as well. This is a preventative measure to ensure that a friend is not breathing into the device for the driver in order to start their car for them.

Ignition interlock devices are often installed in cars belonging to those charged with a DUI. Often the installation of such a device is mandatory in accordance with the sentence of a criminal charge, and are installed and maintained at the expense of the offender. Depending on the Province, the installation of an ignition interlock device can reduce the length of a license suspension.
