With the advent of portable technology in recent years, law enforcement now have more tools at their disposal during the course of an Alabama DUI arrest. The physical field sobriety tests (FST) are only one part of their capable offense against drunk driving; if a driver displays intoxicated behavior, police may also ask the subject to breathe into a portable sensor that measures blood alcohol content.
The most famous portable alcosensor is the Breathalyzer. This instrument relies on chemical oxidation to calculate the alcohol level. However, the Breathalyzer is being phased out for newer forms of breath testing using infrared spectroscopy technology.
Common alcosensor devices are:
› BAC Datamaster
Regardless of the device, these instruments rely on indirect measurements of blood alcohol content. The only accurate means of measurement is a detailed analysis of a blood sample. It also does not measure a person’s actual level of intoxication, as everyone’s alcohol tolerance differs.
How can I defend my DUI charge based on an alcosensor test?
Every unit has its own strengths and weaknesses that a skilled Alabama DUI attorney can expose. The temperature of the suspect, the air temperature, the user’s breathing pattern, and the instruments calibration—among other variables—affect the test’s efficiency. All of these areas will be explored by an experienced DUI lawyer. If any potential for error has been uncovered, it will be exposed in the courtroom.
