Explanation
If you drive with a breath or BAC .08 or more, by law you are presumed to be driving under the influence (DUI). A blood alcohol concentration of .08 or more is considered to impair driving ability significantly. This level of alcohol in the bloodstream can lead to decreased coordination, impaired judgment, reduced reaction times, and inhibited decision-making capabilities, all of which increase the risk of accidents on the road.
