A newspaper investigation has found that up to 560 license plates belonging to Detroit's school district have vanished, and no one knows why.
The missing state-issued municipal plates don't have annual renewal fees and aren't tied to a vehicle identification number. It means that law enforcement would have a difficult time tracking a getaway car or identifying a reckless driver with an unauthorized municipal plate.
The Detroit Free Press reports that the Detroit district struggled to explain what happened to the missing plates. State officials don't monitor the plates once issued and there are few rules regulating them.
District spokeswoman Chrystal Wilson says the newspaper's findings have surfaced another example of a lack of processes. She says the district will develop policy and administrative guidelines for unauthorized plates.
