To the one service alcohol to underage kids, yes ... and on the spot.
For an underage person, their actions, mannerisms, slurred speech, etc, are all tell tale signs of consuming alcoholic beverages. They may not be able to issue a citation but they sure as heck can (and should) call the parents to come pick them up in person!!
Yes. There are many sources of error in alcohol breath testing machines.
"Yes alcohol breath testers work. You breath into a breath tester and it reads the alcohol content of your breath. Cops can pull over people and test them to see if they are drunk, and can arrest you if you are."
No, blood alcohol level and breath alcohol level are not the same. Blood alcohol level is a direct measurement of the amount of alcohol in the blood, while breath alcohol level is an indirect measurement based on the amount of alcohol in the breath, which is correlated with blood alcohol level.
Breath alcohol level refers to the amount of alcohol vapor in the breath. Alcohol is excreted into the lungs from the blood in a fixed proportion to the amount in the blood. Therefore, measuring breath alcohol gives an indirect, but accurate, measurement of the amount of alcohol in the blood, and the degree of impairment to brain function.
The odor of an alcoholic beverage on the breath will dissipate with time. It's also possible to cover the odor with breath mints, mouthwash, etc. However, doing so will not prevent the detection of the alcohol in an alcohol breath test.
None, unless they contain a lot of alcohol. Alcohol breath is caused by alcohol leaving the bloodstream via the lungs. It does not originate in the mouth.
No not unless you are underage or asked if you are able to drive the vehicle home.
on how your breath smells
A breath alcohol test measures the amount of alcohol in your body by measuring the amount of alcohol in the air that you exhale. The test can be administered by a a device that is electronic or manual.
One regular drink containing an ounce of alcohol will make your breath smell.
Research indicates that breath tests can vary at least fifteen percent from actual blood alcohol concentration. The alcohol breath test may be higher than their true blood alcohol. These reading can be used in court as evidence.
The Zero Tolerance law allows for underage drinkers to lose their licenses if they have a BAC of .02. The adult level is .08, so underage drinkers face stiff penalties at a much lower BAC.
