Michigan Gov. Rick Snyder has signed a law letting full-time college students postpone jury duty until the end of the school year.

The governor on Tuesday also approved rules for indoor trampoline parks where adults and kids can bounce around for a fee.

Snyder says jury duty is "an important part of our civil responsibility" but can be disruptive to college students' studies. A similar exemption already exists for high school students.

The other law requires trampoline courts to publicly display rules and inform customers of the activity's inherent dangers. Trampoliners also must adhere to rules specified in the law.

A trampoline user, spectator or operator who violates the law is liable for damages in civil lawsuits.
