How long does it take for 1 shot of vodka take to pass an ignition iterlack device?

The time it takes for one shot of vodka to pass an ignition interlock device varies based on several factors, including individual metabolism, body weight, and the specific device's sensitivity. Generally, alcohol can remain detectable in the breath for several hours after consumption, with a typical elimination rate of about 0.015% blood alcohol concentration (BAC) per hour. For most people, it may take at least a couple of hours for the alcohol from one shot to be cleared from their system sufficiently to pass an interlock test. However, it's important to remember that individual responses to alcohol can vary significantly.
