This is the only highway on the list which had more than 1000 fatalities reported. In fact, in 2008, it was voted as the most dangerous highway to drive on in the entire United States. A total of 834 accidents were recorded on the study date, which also indicates that some of the most dangerous drivers are on the road.
The scenery along this route is unparalleled, especially when it comes to the “Grapevine” part of the highway, so named after settlers who had to cut their path through the vines. The scenery also contributes to the dangerous driving conditions because of its many twists and turns that lead throughout the mountains.
Due to the fact that California is one of the largest states in the U.S., along with the second most populated, there are hundreds of thousands of people who go through these highways on a daily basis. When you mix this in with the fact that there are tourists on the road, commercial drivers, and people who are commuting to different states via these highways, the threat becomes ever more present for everyone who has to drive on these roads.
