Traffic control: driver license; issuance of a restricted license; modify. Amends sec. 304 of 1949 PA 300 (MCL 257.304).

SB 580 modifies Michigan's rules for issuing restricted driver's licenses to individuals suspended due to DUI convictions. It requires installing an ignition interlock device and completing a specialty court program before eligibility, limiting driving to work, treatment, school, or essential appointments. The restricted license remains valid for at least one year, during which any alcohol use could trigger further suspension. This applies to those with two DUI convictions or one DUI plus prior related offenses under Michigan law.
