Michigan has new laws that make it a crime to intentionally shine a laser at an aircraft or a moving train.
Gov. Rick Snyder's office says he signed the legislation Tuesday.
The main law would make shining a laser a felony with a maximum punishment of five years in prison and a $10,000 fine. It's already a federal crime, but state police said a Michigan law would help investigators quickly pursue people who are pointing lasers near airports.
A laser pointer can temporarily blind a pilot.
