DUI & Driving Under The Influence:
DUI Blood Alcohol Content :
BAC is most conveniently measured as a simple percent of alcohol in the blood by weight. It does not depend on any units of measurement. In Europe it is usually expressed as milligrams of alcohol per 100 millilitres of blood. However, 100 milliliters of blood weighs essentially the same as 100 milliliters of water, which weighs precisely 100 grams. Thus, for all practical purposes, this is the same as the simple dimensionless BAC measured as a percent. Since 2002 it has been illegal in all 50 US states to drive with a BAC that is 0.08% or higher.

Field Sobriety Test :
An increasingly used field sobriety test involves having the suspect breathe into a small, handheld breath testing device. Called variously a PAS (preliminary alcohol screening) or PBT (preliminary breath test), the units are small, inexpensive versions of their larger, more sophisticated instruments at the police stations, the EBTs (evidentiary breath test). Whereas the EBTs usually employ infrared spectroscopy, the PAS units use a relatively simple electrochemical (fuel cell) technology. Their purpose, along with other FSTs, is to assist the officer in determining probable cause for arrest. Although because of their relative inaccuracy they were never intended to be used in court for proving actual blood-alcohol concentration, some courts have begun to admit them as evidence of BAC.
