New research is tying a lower legal blood-alcohol limit to fewer alcohol-related crash deaths, according to a study involving researchers from Colorado State University and UC Irvine School of Medicine.
The study examined the impact of Utah's 0.05 blood-alcohol limit, which was passed in 2017, by comparing the state with six neighboring states.
The research conducted by Colorado State University and UC Irvine School of Medicine focused on the period following Utah's decision to lower the legal limit. This change means that drivers in the state can be legally charged at a 0.05 threshold.
