When is it necessary to have an Ignition Interlock Device installed in your vehicle?

The requirement to have an Ignition Interlock Device installed in your vehicle is mandated in situations where an individual has two or more operating under the influence offenses and is seeking a hardship license or reinstatement. This measure is intended to enhance road safety by preventing repeat offenses. The device works by requiring the driver to provide a breath sample that indicates their blood alcohol concentration (BAC) before allowing the vehicle to start.

When someone has multiple offenses, it reflects a pattern of behavior that necessitates stricter measures to ensure that they do not repeat their mistakes. Hence, the installation of the device is a safeguard not only for the individual but also for the public, as it blocks the operation of the vehicle if the sample shows that the driver is impaired.

Other options, such as having only one offense or maintaining a clean driving record, do not trigger this requirement, because the installation of an Ignition Interlock Device is specifically linked to the history of operating under the influence violations and the seriousness of those offenses. Additionally, being under the age of 21 does not automatically necessitate the installation of an Ignition Interlock Device unless there is a relevant offense history.
