UNDATED (KDAL) - Those planning to attend a St. Patrick's Day party this weekend are reminded by law enforcement to plan ahead for a sober ride home. Since St. Patty's Day is historically a dangerous drinking and driving period, Minnesota and Wisconsin will beef up their patrols on the roads to try and prevent alcohol related crashes. In Minnesota there have been 11 traffic deaths in the last 5 years during the St. Patrick's Day holiday and since 2008, the number arrested for DWI on that date has gone up each year. There were 346 arrests last year. A DWI offense can result in loss of license for up to a year, thousands of dollars in fines and possible jail time.
