Alternate Names : Alcohol Test - Breath, Breathalyzer
What do the test results mean?
Normally, blood alcohol level is zero. The air a person exhales will contain no alcohol. The yellow bands in the tube will not change color.
If blood alcohol levels are elevated, some of the yellow bands in the glass tube will change from yellow to green.
If one band is green, blood alcohol levels are .00% to .05%.
If two bands are green, blood-alcohol levels are .05% to 0.1%. At these levels, the individual will suffer from reduced muscular coordination, impaired judgment, and longer reaction time due to alcohol intake.
If three bands are green, blood-alcohol levels are 0.1 to 0.15%. At these levels, a person is considered legally drunk in many states. Levels are lower in some states.
