This blog addresses alcohol readings from interlock devices in the Michigan drivers license restoration context.

It is a violation if the interlock device measures alcohol at or above .025 and there is no test below .025 within 5 minutes. For example, if an interlock device measured alcohol at .026 and a subsequent test 6 minutes later was .020, this would be a violation because the subsequent test was more than 5 minutes later. However, if the .020 reading was 4 minutes after the initial reading, then it would not be a violation.

It goes without saying that you want to avoid drivers license restoration Michigan violations. You should also keep in mind that the interlock company is required to keep track of all alcohol readings at or above .025, whether or not they are violations. These readings will be reported on the final report sent to the Secretary of State. This final report will be reviewed in detail at your hearing when you are seeking a full drivers license.  In other words, any alcohol reading at or above .025 is important and may affect your future driving privileges.

I would urge you to contact a Michigan license reinstatement lawyer to discuss any questions you might have about any alcohol reading or violation that you may have had. A Michigan license restoration lawyer should be able to give you some advice on how best to proceed.
