WRONG! vodka does give off an odor.All alchohol gives off an odor.That is an old myth about the vodka.
Alcohol itself is odorless. It's the additives in the drinks that you smell. You could drink non-alcoholic beer and still smell like you've been drinking.
Every "routine" traffic stop is a full-blown criminal investigation. The police officer actually begins a "pre test" when he first walks up to a citizen's vehicle. This is called a Diverted Attention Task test. He asks the citizen to do two or more things at once, looking for any sign of imperfection. An example is ordering a driver to retrieve his license and answer numerous questions at the same time. If the citizen stops looking for his license in order to answer the question, or if he cannot find his license quickly, he automatically fails the test. (In the car selling business, 90% of my customers had difficulty finding their license for me to make a photocopy of it.) The government's National Highway Traffic Safety Administration determined that 26% of citizens fail this test at 0.00% BAC. Note that this government test of its own test did not take into account the financial greed factor of the cops (or the courts), nor did it take into account any personal prejudices of the officer towards a particular citizen.
While conducting his Diverted Attention Task test, the officer is attempting to smell the citizen's breath, searching for the so-called odor of alcohol. However, ethyl alcohol (ethanol) has zero odor. "Near beer" (zero percent alcohol) has odor, and alcohol flavorings (zero percent alcohol) also have odor. Syrupy flavorings, such as found in liqueurs, stick to the mouth and remain long after the alcohol is gone, giving a characteristic odor. Pure Grain Alcohol, such as Everclear, has no odor, despite being almost 200 proof (virtually 100% pure alcohol). Beer, despite being the weakest of alcoholic beverages, has the strongest odor from its flavorings.
Breath sprays, such as Binaca, have a high concentration of alcohol in them. Binaca can even cause a false breath-alcohol test result of 0.811% BAC, which is nearly double a fatal dose of alcohol poisoning. Incidentally, Listerine mouthwash can cause a false breath-alcohol test result of 0.43% BAC, which is near the level of coma. These effects last as long as 30 minutes to an hour.
Smoking a cigarette at this point is considered by police to be an attempt to cover up the so-called odor of alcohol. It is not considered a sign of nervousness brought on by legal nicotine addiction.
The field sobriety test is a "failure-designed" test, using many unusual acts and skills as its baseline. These unusual skills and acts are virtually impossible to perform without extensive practice, yet citizens are given only one chance to pass. This means that many false positives result merely because it is not a true test. The DWI Law and Science Journal concluded that 46% of test results are false positives. In other words, 46% of sober people are "too drunk to drive." This independent test did not take into account the financial greed factor of the cops (or the courts), nor did it take into account any personal prejudices of the officer towards a particular citizen. A "normal function" field sobriety test still produces a 14% false failure rate, although this test is not used by police. Actually, there is no passing grade for the field sobriety test, and police generally do not use any sort of preprinted grading form, nor do police follow any standardized series of specific tests. (This tends to result in "xeroxed" generic allegations of failed performance, which read identically for thousands of arrestees.)
