Tennessee Breath Test

The fastest way to obtain a blood alcohol reading is through the use of a breath testing device. The ECIR is the most common of these used in Tennessee. This instrument enables police to acquire a potentially admissible piece of evidence right at the scene. While this is incredibly convenient for law enforcement, accuracy is still a major concern. Everything from body temperature, calibration and electrical frequencies can affect the readings of breath analyzers.

Generally a police officer will observe reckless driving or intoxicated behavior through a sobriety checkpoint. Law enforcement will then initiate either field sobriety tests or chemical testing. At this time the driver should be informed that they are not required to take any chemical test; however this may result in a long-term license suspension. A breath testing device is generally preferred since it is minimally invasive and typically more accurate than the field sobriety tests that rely on physical abilities. To complete the breath test, the driver will blow into the instrument for an amount of time until the reading can be generated. It is worth noting that it could be difficult for people with medical conditions to exhale for so long. If the reading generated is at .08 or above, the suspect may be charged with DUI.
