How Blood Alcohol Content is Calculated in a DUI Arrest

The single most conclusive form of evidence heard against a defendant charged with DUI, or driving under the influence of drugs or alcohol is blood alcohol content. Also referred to as BAC, blood alcohol content is determined in three distinct techniques. All three are often successfully utilised to prove the exact level of sobriety a defendant exhibits. The defendant’s BAC can be entered as evidence in a courtroom in nearly every state in the U.S.

The initial method in which BAC is determined is through a breathalyser examination. The accused driver blows a forceful stream of air into an analysing device, which then screens the level of alcohol present. Most TV shows and films glorify the breathalyser test, but it is in fact among the least accurate indication of blood alcohol content of the BAC tests used. You’ll often find many TV shows feature drunk driving from the officer’s perspective and portray them utilising a breathalyser unit to check BAC.

The arresting officer informs the accused that they must submit to a breathalyser test. Failure to comply can lead to the DMV, Department of Motor Vehicles, imposing much more severe consequences and license suspensions than if you had merely cooperated and provided a breath sample. Drivers over the legal limit can plead remorse or offer mitigating factors, and even have the evidence suppressed. Drivers who didn’t submit to testing cannot later argue on their behalf as successfully. Additionally, in most states, once you refuse to submit to a breath test, an added harsh penalty can be added from the court. Typically, this ends in a lengthier license suspension period, a higher fine or additional prison time.

A different determining method is a blood test. This testing is incredibly precise and regarded as the most trusted and reliable type of testing. It is virtually impossible for most attorneys to refute this sort of proof of drunk driving but an experienced drunk driving attorney can still examine the evidence from all perspectives as a way to search for potential defences. These range from medical explanations, faulty equipment, etc…
