Passing your ignition interlock test after drinking

There’s no certain way to determine how long it takes to pass an interlock test after you’ve been drinking. How much you consumed and how long ago you drank both definitely matter. There are many factors that can all play a part in the amount of time it takes for your body to process alcohol.

Providing answers to questions like this isn't a simple task because it depends on a number of things. Passing a breath test on an ignition interlock device after drinking isn’t just a matter of time or quantity. Your breath alcohol concentration (BrAC), which is what an interlock device measures, is affected by several factors. Together, they all play a part in the length of time it takes your BrAC to return to zero which will allow you to successfully complete an interlock test.

If I drink at night, can I pass my ignition interlock test the next morning?

Sleep doesn’t guarantee that you’ll be able to pass an ignition interlock test. There are truly no shortcuts – sleep, energy drinks, coffee, water, or any solutions found on Google – that will ensure a successful breath test.

Plenty of sleep is definitely a good idea, but sleep itself doesn't make alcohol disappear from your system. It simply allows a longer period of time to go by before you take your interlock test the morning after drinking. That gives your body more time to eliminate any alcohol in your system.
