I agree with David’s assessment that the code be changed to be more specific to ethanol and less specific to technology. Doing such opens opportunity to promote systems that reduce the likelihood of false positives. Currently, certain levels of acetone and/or methane can cause a false positive due to diet. These false positives may potentially lead to the person being convicted of a Class 1 misdemeanor and their license revoked. Convicted or not, the administrative costs dealing with such burdens are not efficient or effective. I realize that other false positives exist with medicine, mouthwash and other alcohol containing products, however, this incremental change is a step in the right direction.
