Blood alcohol content, or concentration, tests are the primary method police officers and law enforcement officials use in proving whether a driver is driving under the influence of alcohol. There are several tests that police officers may use when determining the BAC levels of an individual. A breathalyzer is the most common method used because the breath analyzer machine is portable and can provides quick estimations of BAC levels and whether a driver should be arrested for DUI. Chemical, blood, and urine tests are also used by law enforcement officials when probable cause warrants it. These tests are more accurate than breathalyzers because they measure bodily fluids or hair samples in a laboratory and may also detect other substances as well as BAC.

Legal BAC Limit
The legal blood alcohol content/concentration (BAC) limit in this country varies by state. However, most have set the limit at .08. The reason for this is that when an individual's BAC is more than .08, he or she is subject to effects from the alcohol that impair his/her ability to drive a motor vehicle, his/her ability to react to external stimuli like pedestrians or other vehicles, and his/her ability to accurately judge distances is hampered.
