From sunny Florida to snowy Michigan, I-75 is a journey filled with both beauty and peril. Here’s why some stretches demand extra caution.

An updated report using data from the National Highway Traffic Safety Administration (NHTSA) sheds light on the most dangerous highways in the United States.  One of those highways runs all of the way from the Southern tip of Florida to the Northern tip of Michigan's Upper Peninsula.

In 2020, the U.S. had the highest fatality rate on the road since 2007, according to recent data published by The Zebra.

Anytime you get behind the wheel of a vehicle, there’s a chance you might get into a wreck. That said, the likelihood of being in a motor vehicle collision dramatically varies depending on which road you’re driving on.  We analyzed the most recent Fatality Analysis Reporting System data to assess which roads, counties, and states have the most risk for drivers based on the number of fatalities in motor vehicle collisions.
