How do you pass a breathalyzer after a night of drinking?
Fiction: You can beat a breathalyzer by hyperventilating, exercising, or holding your breath before you blow. Fact: An often-cited decades-old study found that hyperventilation and vigorous exercise did indeed lower subjects’ BAC readings by as much as 10%.
Conversely, holding their breath actually increased subjects’ BAC readings by up to 20%. Unfortunately, these activities can also render one light-headed and gasping for air – behavior that would undoubtedly capture the attention of law enforcement officers who suspect an individual of being under the influence.

What happened? BAC rates The problem is likely that you did not wait long enough after all. People often misjudge just how intoxicated they are and how the alcohol can impair their driving and judgment.

- This is true for almost everyone, regardless of their weight, height, age or any other factor.
- If you drink, that’s how fast your body can metabolize the alcohol and get it out of your system.
- So, how long did you really wait? An hour? Two? Depending on where your BAC started, it may not have fallen as far as you think.
For example, imagine that you started right at the legal limit of 0.08 percent. In the first hour after you put your drink down, your BAC would only fall to 0.065 percent. Another hour after that, you would hit 0.05 percent. In three hours, you’d reach 0.035 percent, and then you’d get to 0.02 percent after the fourth hour.
- Alcohol would remain in your system even after five hours, though just at 0.005 percent.
- It would take roughly five hours and 20 minutes for you to completely metabolize all of the alcohol you consumed and get back down to 0.00 percent.
- And that is just if you start at 0.08, which is right at the legal limit.
If you were at 0.10 when you stopped drinking and you waited for an hour, you would still be at 0.085 percent when you got in the car. Remember, the way you feel can be deceptive. It depends on your alcohol tolerance and how often you drink.
