World's 10 dangerous roads... Top 10 of the scariest, most unsafe highways, bridges and roads ever built. Car and truck accidents and deaths are a common thing on these roads.

About 1.3 million people die in traffic accidents every year. The World Health Organization has declared 2011-2021, "A decade of action for road safety."

But while many of those deaths could be prevented by better driving, there are some roads that test the skill, and courage, of any driver. Whether it's hairpin bends, sheer mountain drops or roads through war zones, here are some of the world's most dangerous roads.

The invention of the road dates back to ancient times thousands of years ago. It was one of the most innovative inventions that connected cities and countries together. Anything that had wheels had an easier time getting by, and it was the birth of road organization as we all figured out which side of the road we would use to move forward. Today, roads are paved with concrete, and man has managed to create roads in the most impossible of spaces, making the world more accessible than ever. However, just because a road can be built, it doesn’t mean that it should. Some roads seem to defy the boundaries that Mother Nature set upon us, but have we ever thought about the fact that the boundaries were set for a reason?
