How to fool the alcohol breathalyzer

Tags: Uncategorized — Author: @ 6:32 pm

From a Calfornia DUI attorney’s blog

“By far, the most overlooked error in breath testing for alcohol is the pattern of breathing….The concentration of alcohol changes considerably during the breath…The first part of the breath, after discarding the dead space, has an alcohol concentration much lower than the equivalent BAC. Whereas, the last part of the breath has an alcohol concentration that is much higher than the equivalent BAC. The last part of the breath can be over 50% above the alcohol level….Thus, a breath tester reading of 0.14% taken from the last part of the breath may indicate that the blood level is only 0.09%.” 9(6) The Champion 16 (1985).

    Thanks Phil!

    First I thought you’ve got some fresh and clever articles on this blog about Finland, it’s people, phenomenons etc…

    Now all you’re articles are just bitching, whining and moaning.

  • Jaakko

    Oops, sorry, commented the wrong article. But you get the point.

    The Friday before last, a mate of mine showed up in a bar, drunk as a skunk, and told me he had driven there. I took his keys and threw him out, came really close to kicking his ass, too. In my book, DUI is just one of those things like boning your own sister; you just don’t do it. I don’t give a shit if people put their own lives at risk, but putting other people on the line by driving drunk just because you’re too lazy or broke (in which case you shouldn’t be drinking in the first place) to call a cab.. Jesus. The legislation here considering DUI is way too lax; jail them, confiscate their cars (for the second offence at the latest), sell them, and distribute the proceeds to the victims of these assholes.

    P.s. Sorry about the bad vibe, but I just feel strongly about this!

    Jaakko, sorry to disappoint. I’ve written over 1,500 posts in 1.5 years, a lot of stuff coverning Finnish people have been covered. Check out the search function, there might be some interesting articles and discussion you’ve missed.

    Come on, Jaakko, hasn’t the ‘Finnish curiosity’ horse been whipped to death a long time ago? And not just on this blog :) .

  • http://www.finlandforthought.net Phil

    I should have began this blog the first day I moved to Finland, back then I had a lot more of these thoughts on “Finnish people, phenomenons”.

    Phil…I think that’s a crock of shit. Mythbusters did an episode on how to beat the breathalyzer tests and this is not a successful strategy.

  • M

    I agree with jaakko. This is getting old really fast. For my daily dose of one-sidedness I might as well check out finnpundit’s blog.

    phil…get real……!!!!!!every finnish know that blowing test shows more that the blood alcohol…but the common thing in finland is(that isnt known in us)that u dont drive if u drink….(maybe u havent notised it yet)so dont bother to mention even it to us!!!!

    For some fun, it’s pretty easy to fool it in the other direction, though. Just put a drop of pure spirit on your tongue prior to blowing and the meter shows a BAC of 0.05 or something like that. Watch the cops scratch their heads looking at you smiling there, sober as a judge and with a blood alcohol content that tells you should be dead. Then it’s off to a blood test which shows 0.00. Support your local lab technician.

    (Then again, the cops might not be amused)

    I dont’t remember in which paper (I-S?) Jörn Donner was lately whining about how he feels entitled for his glass of wine with dinner and jump behind the wheel right from the table without fear of being breathylized.
    Redicilious. Most of the people who has difficulties to stay away from alcohol when they are going to drive (exept Phil?) are middle aged or older -old farts- men like Jörn here. Of course stupidity knows no ages but this glass of wine, c’mon, drink milk.
    When you get your driver’s licence in finland, you pledge to obey certain rules, and this is one of them. If you don’t intend to follow them, why have the licence in first place. Like aet75 told, call a cab.

  • Freeridin’ Franklin

    One glass of wine won’t put you over the legal limit anyway.

    Here‘s a counter. According to it a man weighing 80 kg can safely drink two 12cl glasses of wine and still be able to drive legally.

    But yes, zero tolerance would be a simpler system. They have that in Ireland, of all places in the world.

  • Tom Byrne

    freeridin franklin commented that we have zero tolerance in Ireland, this is not the case, generally speaking a person, depending on their size and make up, etc. can have 1 – 2 glasses of wine or beer and drive within the legal limit, but mostly people, usually older more experienced people drink a lot more and drive. This is most common in rural areas where there is no public transport, I’ll exclude myself out for obvious reasons but thousands of Irish motorist have drank maybe 6 or 7 pints of beer and drove home for years, never even been invoved in an incident never mind an accident, I know certainly many people in this cathegory.

    Hi Phil,

    great point about breath has an alcohol concentration that is much higher than the equivalent BAC. In Australia when breath tested, the officer asks you to blow one continuous breath until they say stop, for at lease 10 to 15 seconds.

    Kind regards & good health,

    Dario.
