Four of the five deadliest highway stretches are located in Southern states, according to a new study released by Canadian fleet management solutions specialist Geotab.

The company analyzed data from the National Highway Traffic Safety Administration and found the Florida stretch of U.S. 1 is . It's important to note the study analyzed each highway on a state-by-state basis, not the entire stretch of each road.

Along the 545 miles of U.S. 1 in Florida, 1,079 deaths were reported in a total of 1,011 fatal crashes over the last decade. That's the highest number of fatal crashes and fatalities, and when Geotab adjusted its numbers for average daily traffic counts provided by the Federal Highway Administration, it remained the deadliest road.

U.S. 1 was also the deadliest highway in Maryland and Maine, but both of those states had relatively low fatal crash rates.

The second-deadliest highway, according to Geotab's study, is Interstate 40 in Tennessee. Along that road, 517 peopledied in 437 fatal crashes over the past decade. I-40 made several appearances on this list, including the third-deadliest stretch of highway – in New Mexico. Nearly 400 people died in a total of 344 crashes, and this was the only stretch of highway in the top 5 that isn't in the South.

The roads with the fourth- and fifth-highest number of deaths were I-65 in Alabama and U.S. 90 in Louisiana, respectively. Both of those roads had at least 270 fatal crashes.

I-95 also appeared twice in the top 10 – in North and South Carolina. Both stretches of the interstate have had at least 200 deadly crashes in the last decade.
