( A police Q) what consist of the BAT test?

Answer 1

A breath alcohol test roughly determines how much alcohol is in your blood by measuring the amount of alcohol in the air you breathe out (exhale).

How the Test is Performed    Return to top

There are various brands of breath alcohol tests. Each one uses a different method to test the level of alcohol in the breath. The machine may be electronic or manual.

One common manual tester requires you to blow up a balloon in one continuous breath until it is full, then release the air into a glass tube. The tube is filled with bands of yellow crystals. The color changes depending on the alcohol content. Count the bands in the tube that have changed from yellow to green. Carefully read the instructions before using the test to make sure you get an accurate result.

If an electronic alcohol meter is used, follow the instructions that come with the meter.
