How long after drinking alcohol can we detect it with a breath alcohol tester? It depends on how much the person had to drink, and how long ago they drank. Alcohol is eliminated at the constant rate of about. You get the idea. Ignition interlock devices are designed to detect a very small amount of alcohol. And in most states, the blood alcohol content BAC level at which the device would say you failed the test is only 0.

And if the device detects alcohol at a lower level, you will be allowed to start the car, but the device will give you a warning, which will be recorded. So there you have it.
