Thousands of truck drivers take to the road and face dangerous situations. Black ice, storms, snow, and heavy traffic are just a few of the hazardous road conditions that truckers encounter daily. Some highways in America are famous for falling rocks, poor visibility, and vehicle accidents. Here are some of the most dangerous roads in the United States:

  1. I-10 in California. - Interstate 10, Phoenix to California: 85 deaths this year. This interstate, spans nearly 300 miles. While it’s one of the most scenic routes, it’s also one of the deadliest. There were more than 45,000 people injured and 700 killed in auto accidents last year in Arizona.

  2. I-26 in South Carolina. During the past year there have been nine fatal wrecks between Jedburg and Interstate 95. A total of 325 people died in 286 wrecks during the last decade, according to the state’s Department of Public Safety.

  3. Highway 550 in Colorado. This winding highway that curls through mountain ranges is full of sharp curves. Boulders threaten to break apart in front of oncoming vehicles, and avalanches can be a real danger during the winter. This southern Colorado two-laner is all-around treacherous: As it climbs out of the former mining town of Ouray, the southern route S-curves through three San Juan Mountains passes (topping out at 11,018-foot Red Mountain Pass) with nary a guard rail or sliver of shoulder all the way to Silverton, 24 miles away.

    Fleets of road-hogging recreational vehicles routinely make this drive, giving you zero room for error, and late fall's wildlife migration and deer hunting season put thousands of deer and bighorn sheep on the move and crossing roadways unexpectedly.

    Ice slickens 550's pavement as early as October. During winter passage it is even dicier: The Million Dollar Highway is directly in the path of a major avalanche zone, and in 1987 the road was buried by a slab avalanche.

  4. I-95 in Florida. If driving on Interstate 95 makes you fear for your life, there's good reason. Often considered to be the most dangerous American highway, this interstate has precipitated the deaths of hundreds of people over the last few decades. It also has one of the worst rates of death per mile. This road is notorious for potholes, improper signs, and narrow lanes.

  5. I-35 in Texas. Sky-high on-ramps and lots of construction make this road one of the deadliest. Just this year, occurred a fatal chain-reaction crash closes northbound I-35 near Waco.

  6. US 129 in North Carolina. AKA the tail of the dragon. Many people confuse deaths from as far away as 100 miles as being "on the Dragon". The Tail of the Dragon is only 11 miles long and the following facts pertain only to those 11 miles. There are more motorcycle deaths on other roads in Blount County Tennessee than there are on the Dragon each year.

  7. I-5 to San Diego in California. This is one of the busiest and most dangerous  highways in America. Interstate 5 (also known as "the I-5" or "the 5") is the major north-south freeway running along the coastline of San Diego County, beginning at the San Ysidro Port of Entry from Mexico and continuing through Oceanside and Camp Pendleton in North San Diego County.

    I-5 connects with several freeways as it crosses through the San Diego, including I-805 which splits off and then rejoins the I-5, SR 905 which heads eastbound to the Otay Mesa Border Crossing, SR 75 which heads west to Coronado Island and Chula Vista, SR 54 which heads east to National City, SR 15 and I-15 which heads northbound along inland San Diego County up to Escondido and Temecula, SR 94 which heads east to Lemon Grove, SR 163 which heads north to join I-15, I-8 which heads west to Ocean Beach and Mission Bay and eastbound to La Mesa and El Cajon, SR 56 which heads east to Santee, and SR 78 which heads east through Oceanside, Vista, and San Marcos.

    The most well-known intersection along I-5 is "The Merge" where I-5 north and I-805 north merge just north of La Jolla and UTC and just south of Del Mar and Carmel Valley. At The Merge, the number of lanes decreases very quickly and traffic comes to a quick stop. many rear end car accidents and multiple vehicle collisions occur on the I-5..

  8. I-15 from Los Angeles to Vegas. An estimated 8 million people drive back and forth every year from southern Nevada to southern California. According to the U.S. Department of Transportation, the 180-mile stretch has with more fatalities than anywhere else.

    The DOT says there have been 466 highway deaths over a 14-year period. Half of those killed were not wearing seatbelts. AAA says the lack of seatbelt use contributes to a higher fatality rate. But AAA and commercial truck drivers who drive the route say there are several other reasons 1-15 claims so many lives each year.

  9. Highway 2 in Montana. This highway is one of the main reasons Montana has the highest fatality rate in the nation.

  10. US Route 1 in Maine. A thriving wildlife population contributes to the high death toll on this highway. Brutally cold winters and poor signage are two other reasons for accidents.

    Stretching from end to end of the thirteen original colonies, from Fort Kent, Maine, to Miami, Florida, the connecting sections of the Atlantic Coast Highway known as United States Route No. Route 1 is a 94-mile section between New York and Philadelphia carries a heavier average traffic than any other road of equal length in the world. Route No. 1 connects New York, Princeton and Philadelphia.
