Ensuring Breath Test Accuracy in Wisconsin OWI Cases

The past evaluations for individuals who have been arrested for operating a vehicle while intoxicated or OWI (known as DUI/DWI in other states) have changed in recent years. The breath test has become the top method for all parties involved, performed by an Intoximeter EC/IR II.

An Intoximeter EC/IR II is a machine that individuals blow into to estimate the percentage of alcohol in their blood. In Wisconsin, driving with a blood alcohol content (BAC) level of 0.08% or greater is considered illegal. However, it’s been observed that even a level of 0.05% or lower BAC can impair driving.

Like other machines and forms of technology, the Intoximeter EC/IR II isn’t immune to problems and inaccuracies. For example, if an Intoximeter EC/IR II hasn’t been calibrated recently, results can vary. If the operator of the Intoximeter EC/IR II isn’t currently certified, experienced in conducting this text and aware of the rules that ensure the highest possible accuracy, this may also affect results. In alcohol-related arrests, decision makers will consider all of these factors in their rulings.

The experienced, client-driven Wisconsin Criminal Defense Lawyers of Huppertz & Powers, S.C., have proven results in challenging the accuracy of Intoximeter EC/IR II tests, whether it’s ensuring the technology is up-to-date, making sure law enforcement officials have followed the proper procedures and more.
