Breath Alcohol Ignition Interlock Device

A breath alcohol ignition interlock is a device that is installed in the dashboard of a person’s vehicle who has been required by the courts to have an ignition interlock device installed in their vehicle as a condition of having their license reinstated in order to drive. In foreign countries that are non-Muslims  

How Does An Ignition Interlock Device Work?

The breath alcohol ignition interlock device is connected to a vehicles starter system. The ignition interlock device can be setup to register a failed reading anywhere from .00% BAC to slightly higher levels, but typically not above .04% BAC.

The breath alcohol ignition interlock device works by measuring the BAC or blood alcohol concentration also referred to as BAL or blood alcohol level of the vehicle’s driver before and during the operation of said vehicle.

If the blood alcohol concentration registered by the ignition interlock system is higher than the preprogrammed level that was set by the company that installed the ignition interlock device, the vehicle will not start. The courts in each state determine the programmed level that will be set by the company performing the installation. Typically this level will be between .02% and .04% depending on the state law.

Also at preprogrammed intervals while the vehicle is in operation, the breath alcohol ignition interlock device will require breath samples from the vehicle operator in order for the vehicle to continue operating. If a breath sample is not provided, or the sample that is registered by the ignition interlock device exceeds the limit that has been preset by the ignition interlock provider, the unit will record the occurrence, warn the driver and then start its alarm, which will consist of the lights flashing, horn honking, etc. before shutting down.

The vehicle operator will be required to blow into the ignition interlock device in order to start their vehicle because the vehicle will not start without first providing a breath sample. Then typically after 10 to 15 minutes of running, the device will request another breath sample. Then a breath sample will be required approximately every 15 to 30 minutes afterwards. The reason for the frequent testing is to prevent a person from having a friend start their vehicle and then allowing the impaired driver to take over vehicle operation.

When it is time for a breath sample, the ignition interlock system will let the driver know that a sample is required. The ignition interlock system will allow enough time for the driver to safely pull to the side of the road before the sample must be given.
