Rules

1.  "Don't touch the Interlock if you're drinking, drunk, or hung over". The Interlock will pick up any alcohol in your system even the next day

2.  "If the unit fails and rule #1 applies take the re-test". The Ignition Interlock device will automatically ask for retests if there is a failed test.

3.  "No swearing at any Interlock Guy personnel". This will make them cry, they will be unable to help you if they're crying.

Note- This is a tough situation for anyone to go through, it is full of panic, worry, and frustration. The rules are in place to minimize those issues to the lowest possible level.
