The most common system for measuring and reporting a person's blood alcohol level is calculated using the weight of alcohol in milligrams and the volume of blood in deciliters (this yields a blood alcohol concentration that can be expressed as a percentage). This system of determining blood alcohol level is the one prescribed by almost every state.
The tool used by the authorities to determine blood alcohol level is called a "breathalyzer". Few patrol cars are equipped with these tools so often times secondary officers or specialists are brought in to administer the test and determine your blood alcohol level.
*Remember that a blood alcohol test is voluntary and, if you are 21 or older, you have every right to refuse to take one.
