The screening device only determines if there is alcohol on your breath not BAL. A method to keep the process moving quickly. The second device as you describe," wraps his/her lips around a tube", test for BAL.

Got it...thanks Colt!

Semp,
It is a screening device. If it lights up red then you do the blow test to determine actual blood alcohol.

Either they don't work or are triggered by other things on your breath. I blew into one of those and it turned red (and I don't drink at all). Cop gave me a stern look for a few seconds then said "go".

I assume the same or very similar to the device held near the mouth and you are asked to count 1 to whatever

Correct it detects iof there is any alcohol in your residual breath, if it detects, then a further test will be carried out. However as it is not exactly a scientific method I am sure they will be errors, more so if the officer has also been imbibing then results will at best be iffy.

Lovely places for TB to hide in over here, ever see them clean in between individuals ??

If you wish to really stuff them up ( at your own expense )

get an alcohol swab from your local pharmacy, and place inside your mouth prior to blowing on the breathalzer unit

Readings on .45- .55 ( normal is 0.05 for legal limit )

Simple request if you blow over 0.05

Ask for the calibration certificate for the unit they are using LOL
