evidence: Gov. Walz signs bill granting driver's licenses to unauthorized immigrants in Minnesota [...] Gov. Tim Walz signed a bill into law at the Minnesota National Guard Armory in St. Paul on Tuesday that will allow unauthorized immigrants to obtain driver's licenses. [...] Minnesota joins 18 states, Washington, D.C., and Puerto Rico where residents can access driver's licenses regardless of immigration status. In Minnesota licenses can be used for driving and identification purposes. The new law will allow previously unlicensed drivers to become insured, and studies have shown licenses improve road safety.
