My friend arrested for drink driving

[kmax]

guys.. i remember taking charcoal or chewing charcol can trick the breath-analyzer, once heard it in movie "Thank you for smoking"

 

any doc or fact to support or deny ?

 

 

and once again, this breath-analyzer is reliable ? after taking blows from many persons before you, will it set to zero reading?

coz one of my friend is caught by road block, his blow is over the limit.

taken to the station, and at there, he was tested and released as it is under limit.

any suggestion ?

[sheep]

NO point trying to siam the system and ride/drive in fear on the way hope praying nothing will happen and no one will notice.

My friend used to work in carlsberg. drunk everynight, he just park his car at the pubs and drive home.

not sure abt charcoal.. but i did watch one of the episode in "mythbuster".. they did a series of test on the analyzer.. nothin seems to b able to beat the analyzer...

A common myth is that breath testers can be "fooled" (that is, made to generate estimates making one's blood alcohol content appear lower) by using certain substances.

 

An episode of the Discovery Channel's MythBusters tested substances usually recommended in this practice—including breath mints, mouthwash, and onion—and found them to be ineffective.

 

Adding an odor to mask the smell of alcohol might fool a person, but does not change the actual alcohol concentration in the body or on the breath. Interestingly, substances that might actually reduce the BAC reading were not tested on the show.

 

These include a bag of activated charcoal concealed in the mouth (to absorb alcohol vapor), an oxidizing gas (such as N2O, Cl2, O3, etc.) which would fool a fuel cell type detector, or an organic interferent to fool an infra-red absorption detector.

The infra-red absorption detector is especially vulnerable to countermeasures, since it only makes measurements at particular discrete wavelengths rather than producing a continuous absorption spectrum as a laboratory instrument would do.

and using Listrine mouth wash or mouth spray can cause the Brathlyzer false reading..

 

On the other hand, products such as mouthwash or breath spray can "fool" breath machines by significantly raising test results. Listerine, for example, contains 27% alcohol; because the breath machine will assume the alcohol is coming from alcohol in the blood diffusing into the lung rather than directly from the mouth, it will apply a "partition ratio" of 2100:1 in computing blood alcohol concentration—resulting in a false high test reading. To counter this, officers are not supposed to administer a PBT for 15 minutes after the subject eats, vomits, or puts anything in their mouth. Also see the discussion of the "slope parameter" of the Intoxilyzer 5000 in the "Mouth Alcohol" section above.

 

This was clearly illustrated in a study conducted with Listerine mouthwash on a breath machine and reported in an article entitled "Field Sobriety Testing: Intoxilyzers and Listerine Antiseptic", published in the July 1985 issue of The Police Chief (page 70). Seven individuals were tested at a police station, with readings of .00%. Each then rinsed his mouth with 20 milliliters of Listerine mouthwash for 30 seconds in accordance with directions on the label. All seven were then tested on the machine at intervals of one, three, five and ten minutes.

 

The results indicated an average reading of .43% blood-alcohol concentration, indicating a level that, if accurate, approaches lethal proportions. After three minutes, the average level was still .20%, despite the absence of any alcohol in the system. Even after five minutes, the average level was .11% — well over the legal limit.

 

In another study, reported in 8(22) Drinking/Driving Law Letter 1, a scientist tested the effects of Binaca breath spray on an Intoxilyzer 5000. He performed 23 tests with subjects who sprayed their throats, and obtained readings as high as .81% — far beyond lethal levels. The scientist also noted that the effects of the spray did not fall below detectable levels until after 18 minutes.

There are rumours that even just gargling with mouthwash also can cause you to fail the breathelyser..... dunno if its true.....

 

But still better not to drink and drive or ride... better safe than sorry

the only way to escape a breathelyser test is to park ur damn car/bike and take a taxi home (or no money, take night rider or night owl). u'll be saving ur license from being revoke, ur arse from being hauled into deep sh*t and let one biker/driver/pedestrian live.

[Zappires]

yup i think the message is clear.as we are talking about lives here.imagine innocent lives are taken.it is not something you can replaced.so don't drive and drive.want to drink go public also can mah!

[Wildswans]

Now there is jail time even for first offenders..... no point party all the way to jail ....

 

so be safe.....

[kianleong]

drink driving is very very bad =X pay the cab fare $20 max or pay ur license and fine and jail terms at least cost u $20k jail terms i think is more than 20k

ur future will have a mark on it =X

20k/20 = 1000 times.. be wise =)

[Wildswans]

If you are worried about your car or your bike, then just leave them at home when you go pubbing with frens..... Unless any of them are willing to do time for you and take the blame, there is nothing worth you risking your life, your money and your records just for convenience
