f an individual is pulled over by law enforcement for drinking and driving, a breathalyzer or blood test could play a vital role in determining future convictions. Driving under the influence (DUI) is a criminal offense, and DUI lawyers are regularly asked which method best calculates BAC levels. In many states, a blood analysis is mandatory. Many people still want to know, however, which assessment is best immediately after a driver has been taken into custody.
What Is Required By Law?
DUI laws vary from state to state. Typically an officer will ask a suspect to take a field sobriety test or to submit to a breathalyzer examination. The first option consists of three elements: the horizontal gaze nystagmus (HGN), the walk-and-turn, and the one-leg test. It is important to remember that before the arrest is made, both assessments are completely optional. Attorneys usually advise clients not to submit to either, as it can provide undisputable evidence.
