A massive new analysis conducted by iSelect Insurance of nearly 130,000 fatal crashes nationwide found something that feels deeply Michigan, it's not the interstates doing the most damage. It's state highways. Yep, the roads with traffic lights, surprise intersections, Farm equipment, delivery vans, and that one driver doing 52 in a 70 for “safety reasons.”

That's more than interstates, us highways, or local streets. In other words, the roads we all use daily are quietly running the danger Olympics.
