From MHSAA.com:

Michigan Varsity basketball teams are allowed two (2) contests during the regular season that are played in two 16 minute halves with one (1) additional 30 second time out.
Purpose: The MHSAA Basketball Committee has for several years discussed the potential for allowing Michigan teams the experience of games played in halves. The original NFHS request for 18 minute halves was denied.
Requirements: All games played in halves must be pre-approved by the MHSAA. Each school participating must complete an after game report.
Time out Allowance: Games played in halves
Three (3) 60 second time outs
Three (3) 30 second time outs
Normal overtime rules and timing will apply: 4 min overtime period, 1 additional 60 second time out
