Inspections are made across the state each year, from September through August. The state website explains that buses earn a "pass" when they are in satisfactory condition, a "yellow" when they are safe, but in unsatisfactory condition, and "red" when buses are unsafe.
Red-tagged issues must be addressed before a bus can go back into service.
Michigan's process is one of the best in the nation, Patrick Dean of Dean Transportation told a WXMI-TV news reporter. According to the Grand Rapids station's report, inspection information for individual buses may be available on the state's website by the 2014-2015 school year.
