During Covid, in Utah, there have been the highest rate of deaths ever recorded due to car crashes. Meanwhile, at approximately the same time another experiment was running.
Late 2018 Utah lowered the blood alcohol level for driving from .08 to .05%. Many, including myself, figured that there would not be a significant difference. But I also commented at the time that this one will be easy to prove or disprove. Deaths and crashes linked to drunken driving dropped by 19.8% since the law took effect. I think one could say that is statistically significant. Glad I was wrong.
