Increased DWI patrols are slated for this weekend. It’s been one-year since enhanced impaired driving sanctions became effective in Minnesota, which includes the use of ignition interlock. Repeat DWI offenders as well as first-time offenders who blew two times over the legal limit must use an interlock to get their license reinstated or face at least a year without a driver’s license. Offenders with three or more offenses are required to install interlock and use it for three to six years, or they will never regain driving privileges. Each year in Minnesota, 40% of the alcohol-related traffic deaths involve repeat offenders.
