Mid-level DWIs, which are those prosecuted with a gross misdemeanor in Minnesota, used to have a blood alcohol concentration (BAC) of 0.2. Today, that has changed. A BAC of .16 is enough to land you with a gross misdemeanor DWI charge.
While that 0.4 percent difference doesn't seem significant, it really is. It's believed that it could lead to around 3,000 more gross misdemeanor DWIs in a single year than if the level had stayed the same. That 71 percent increase could cause significant problems for some.
