DUI Breath Testing

Breath tests utilized in driving under the influence cases offer only an roundabout way of measuring the blood alcohol levels. Breath tests estimate BAC using specific scientific presumptions in which are not always always suitable to the person being tested. Breath-testing devices make widespread assumptions concerning the driver’s blood/breath partition percentage, breath temperature, and several other factors.
Motorists whose chemical tests reveal a BAC of .08 percent or better commonly worry that this indicates an automatic conviction, however that is far from the truth. Breath tests along with other chemical tests are generally effectively challenged.
