The Most Dangerous Highways in America

The United States is connected in many ways—one being the web of highways crossing the country. However, while many will drive these daily without issues, accidents are inevitable. According to Geotab, a vehicle data management company, some highways are more accident-prone than others. 

Geotab calculated what is known as a “fatal crash rate”, using data from the National Highway Traffic Safety Administration and average traffic flow information from the Federal Highway Administration from the last ten years to determine which highways had the highest rate of accidents as opposed to others. The ten most dangerous highways are as follows. 

1. US-1, Florida

1. US-1, Florida

With the number of people flocking to Florida on a regular basis, either to escape the winter in colder climates or simply for a vacation, it’s no surprise that the portion of the US-1 in Florida is the most dangerous.

With over double the number of crashes of the next highway, the US-1 had 1,011 crashes reported in the last ten years, with a frightening 1,079 fatalities.

2. I-40, Tennessee

2.  I-40, Tennessee

The I-40 cuts across the entire width of Tennessee, connecting many of its largest cities and cutting through Nashville, making it a vital part of the state's transportation.

Covering as much ground as it does, it ranks as the second most dangerous highway on the list, with a shocking 427 crashes and 517 fatalities.

3. I-40, New Mexico

3. I-40, New Mexico

Cutting through Albuquerque, New Mexico, and connecting Arizona and Texas, this stretch of the I-40 saw 344 crashes and 395 fatalities in the last decade.

The I-40 is a heavy presence on this list as it’s the third longest highway in the US. Spanning such long distances, it's easier for numbers to start adding up. 

4. I-65, Alabama

4. I-65, Alabama

Coming in at a close fourth, the I-65 in Alabama had 336 crashes in the last ten years, with an average of 34 deaths a year.

As this highway connects over half of the state's largest cities, cutting through the entire state lengthwise, it's understandable that it would be one of the most dangerous highways.

5. I-90, Louisiana

5. I-90, Louisiana

In the past decade, this portion of the I-90 that goes through Louisiana has had an alarming 271 crashes. This has sadly resulted in 295 fatalities. 

This is even though the portion between Lafayette and New Orleans, two of the largest cities in the state, primarily consists of local traffic, with most other travelers taking the I-10.

6. US-83, Texas

6. US-83, Texas

The US-83 runs from the top of Texas to the bottom and is the longest highway in the state. While much of it covers rural, scenic routes rather than city areas like other highways on this list, it still makes the cut.

With 268 crashes in the past ten years and an average of 26 fatalities a year, it is one of the least fatal of these dangerous highways. However, it remains extremely dangerous.

7. I-40, Arizona

7.  I-40, Arizona

Considering the I-40 is one of the longest highways in the United States, connecting the East and West Coasts, it makes sense that it would be on this list so many times.

What is interesting is that despite directly connecting to the I-40 in New Mexico, in Arizona, it only had 249 crashes with 293 fatalities. That's ten fewer crashes a year than New Mexico.

8. I-95, South Carolina

8. I-95, South Carolina

The I-95 is on this list twice, both portions in the Carolinas. This makes sense, as both states are along the way for anyone in the north fleeing south to Florida for a bit of sunshine.

This means the highway sees much more traffic than just local. The I-95 in South Carolina had 244 crashes and 301 fatalities in the past decade.

9. I-5, Washington

9. I-5, Washington

As one of the shorter highways on this list and the furthest north by quite a bit, it may come as a surprise to see this stretch of the I-5 on the list.

Despite its length, it is still the busiest highway in the state of Washington and was reported to have 245 crashes with 258 fatalities over the last decade.

10. I-95, North Carolina

10.  I-95, North Carolina

With 201 crashes in the last decade, the I-95 cutting through North Carolina is the least dangerous on this list, but it is still one of the most dangerous highways in the US.

Also known as the Blue Star Memorial Highway, this top ten dangerous highway should be approached with as much care as any other on this list.
