Michigan lawmakers are continuing talks on energy policy and changes to the state’s auto insurance system. Legislators now have two days left in the two-year session. They voted Tuesday for higher speed limits on rural highways and to give schools more flexibility on “zero-tolerance” expulsion and suspension requirements. But some major items, including a rewrite of 2008 energy laws, remain bottled up. Majority Republicans also have proposed a scaled-back plan to rein in medical costs for people seriously injured in car crashes.
