there are many factors that can cause it. thats why if you blow positive at a check you have to go into the van and do 3 tests over 20 minutes on the more accurate machine

my friend blew over 0.05 (which is the limit here) and then when he did the tests in the van he was only 0.03. the hand held breathalysers ones arent as accurate



it doesnt work that way here.
if they can get anyhting to say you over the limit, they are going to lock you away and destroy your life.
you have any idea what it costs to have that thing installed in your car?
and thats on top of the fines, "rehab", lawyers, etc...

I think in Ohio you can refuse the breath test..but then they haul you off for a blood alcohol test.

If I had maybe 2 drinks over the last hour and I was corralled, I would go for the blood test. It's far more accurate and less subject to the errors seen with brethalyzers.

I've already warned my wife that if it happens, she'll have to come pick me up.

Not to mention the longer you wait, especially with the increased heart rate from stress, the better the chance to reduce the alcohol in your system.

There are a lot of variables in the equation for what shows up on a breathalyzer:

strength of the drink (unless you're drinking miller or bud, most drinks are MUCH stronger than the typical figures for "one drink"

size of the drink (most of the facts and tables you see are based on 12 ounce beers with about 5% alcohol and many/most drafts are 12 ounces or more)

body weight of the drinker

time since last drinking (you metabolize about the alcohol in a pint of 5% ABV beer per hour)


That said, I would suspect the accuracy of an over the counter breathalyzer and expect that it would be tuned to be overly sensitive so as to help the manufacturer avoid lawsuits by having the machine tell a person they were under the limit when they turn out to be over it.


Incidentally, one of the "variables" that does not affect BAC IN THE LEAST is your tolerance for alcohol. It doesn't matter how much of a "seasoned drinker" you are - your BAC will still show how much alcohol is in your system - you might be more or less "used to" handling higher amounts of BAC than someone else, but your BAC will never be based on your tolerance and will ALWAYS be based purely on your consumption (and metabolism) over time.

you metabolise about one drink an hour
you piss them out a little faster
sweat them out even faster
and breath them out as well.


breathalizers are a bad measure of BAL.


and most beers are around 4.5% some of my favorites are even a little lower. 3.5% or so, and a few are much higher. my scotch ale is around 8%.

Metabolize is basically shorthand for excrete, sweat, breathe.

My dad was a parole officer for 35+ years and for around 20 years, he taught the alcohol awareness class you were required to attend when you got a DUI in PA. From the age of about 16 until he retired when I was in my late 30s, I heard all the stats and speeches about drinking and driving more times than I care to remember from him.

Yes you "metabolize" about one drink per hour - about... which means on average - different people have different metabolic rates. As you're aware, different types of alcoholic beverages have different amounts of alcohol in them.

For years, "drinks" were equated as one 12 ounce beer = one glass of wine = one mixed drink... all with approximately 15 ml of alcohol in them - this is a relatively huge fallacy ESPECIALLY if you're drinking mixed drinks which will vary tremendously in terms of alcohol content.
