What state and device do you have?

More likely than not you will get a letter asking what happened. If your answer is not satisfactory they can add time to your interlock period among other things.

Did you only blow once? Explain everything in detail.

If you do not feel you can stop drinking then you may have to get a personal breathalyzer first to blow in to check your BAC before trying the interlock.
