St. Augustine, FL – All drivers in Florida who have a blood alcohol concentration above the state’s limit are committing a crime. However, it can be difficult to know whether a person has passed the legal threshold of a .08 blood alcohol concentration without testing equipment. Drivers should always err on the side of caution and not operate their vehicles if they have been drinking. Anyone who has already been charged with a DUI should look into getting legal help as soon as possible after an arrest

How many drinks will cause a person’s BAC to rise above .08?

There is not an exact way to know a driver’s blood alcohol concentration without some kind of testing equipment. However, there have been some general guidelines that are given as estimates. A person who weighs between one hundred and one hundred eighty pounds will usually need about three to four drinks within an hour to reach the legal limit. A standard drink is defined as twelve ounces of beer, five ounces of wine, or one and one half ounces of hard liquor. People who weigh more or have faster metabolisms can reach this limit more slowly. It is also possible that whether a person has eaten recently, their hydration level, and even their stress levels can affect their blood alcohol concentration. This can be problematic for people who are trying to manage their alcohol consumption, as it is almost impossible to know their BAC at any given moment once they have started drinking. 

Police procedures for testing

Florida’s DUI laws and procedures allow any police officer to request a test for either blood, breath, or urine to test for the presence of alcohol or controlled substances. This is printed on all Florida driver’s licenses, and it is called the implied consent law. A breath test after a mandatory observation period is the standard way to test for alcohol in a suspect’s bloodstream. The person is supposed to be isolated in a testing room, and provide two separate samples to confirm their accuracy while the officer watches. The machines are equipped with a slope detector that is supposed notify the user that a sample is invalid if there is too much moisture in the machine. 

A test of a person’s urine is normally only used to test for drugs, while a blood test is reserved for medical emergencies or other situations where a breath test cannot be taken.
