Michigan Compiled Laws, Chapter 257. Motor Vehicles § 257.1329

Sec. 29. If a person, including a nonresident of this state, engages in conduct prohibited by this act or a rule or order and has not filed an irrevocable appointment of the secretary of state as an agent for service of process, and personal jurisdiction over him cannot otherwise be obtained in this state, the conduct itself authorizes the administrator to receive service of process in a noncriminal proceeding against that person or his successor, if that proceeding originates in conduct that is a violation of this act or an administrative rule hereunder. The service shall have the same force and validity as if served on the person personally.
