Breathalyzer in car [Explained]

What is an in-car breathalyzer? These devices, also known as ignition interlock devices or IIDs, are used to measure the alcohol levels measured in your breath and prevent you from starting your vehicle while intoxicated.

The alcohol measured in your breath from the IID is known as your breath alcohol concentration (BrAC).

The installation of these car breathalyzers is usually required for people who have been convicted of drunk driving. In most cases, the installation of a car breathalyzer in their vehicle helps them regain their driving privileges.

To use Intoxalock's car breathalyzer device, all you have to do is push the button in the middle of the device, blow into your device, and then start your car upon a passed test.

We recommend waiting at least 15 minutes after eating or drinking anything before submitting the breath sample for your Intoxalock car breathalyzer.

This way, you won't have any remaining chemicals in your mouth that could affect the results of your breath sample.
