That depends on the country, state/province, and sometimes age of the driver.
It indicates an illegal level of intoxication.
on how your breath smells
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.
No. An alcohol breath test is only an estimate of the actual blood alcohol concentration, which can only be determined by drawing and analyzing a sample of blood.
If you breath or have a blood alcohol level of .08 your license will be suspended.
Blood alcohol level is determined using blood, breath, urine, or saliva tests. Most law enforcement agencies use the breath testing method to determine blood alcohol level.
No, but it is a common illegal level for driving a motor vehicle.
No, but it can sometimes lead to a falsely high BAC reading on an alcohol breath testing machine.
"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."
All states have a zero tolerance for underage drinking. If the blood content is .02 or higher it is illegal.
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.
The maximum BAC (blood-alcohol content) you are legally allowed to have before being considered illegal is 0.08% in the US. In the UK the limit is 35 micrograms of alcohol in 100 milliliters of breath.
