Juveniles: crimes; transportation of juvenile who commits a crime with an adult; clarify. Amends sec. 16 of 1939 PA 288 (MCL 712A.16).

HB 4018 clarifies when juveniles aged 16-17 can be transported with adults during custody. The bill specifies that juveniles may only be transported with an adult who is 25 or younger if both were taken into custody simultaneously for the same offense or occupied the same vehicle during the offense. It requires juveniles to be separated from adults "at the earliest available time" after arrival. This directly affects law enforcement and juvenile justice systems handling cases involving older juveniles (16-17) and young adults (under 25) who commit offenses together. The amendment updates Michigan's Probate Code to provide clear, specific conditions for this exception to standard juvenile detention rules.
