Embarking on a road trip often conjures images of scenic highways and carefree adventure, but not all routes are created equal. Some roads in the U.S. are infamous for their treacherous conditions, high accident rates, and unpredictable weather patterns. Whether it’s hairpin turns, narrow lanes, or extreme isolation, these routes can turn a dreamy drive into a nightmare. Here’s a guide to 15 of the most dangerous U.S. road trips—and the reasons why they’re best avoided or approached with extreme caution.
1. Dalton Highway, Alaska
Stretching over 400 miles through remote Alaska, this route is notorious for its icy conditions, lack of guardrails, and complete isolation. The road is primarily used by truckers and has limited access to gas stations or emergency services. In winter, subzero temperatures and blizzards make it one of the most hazardous drives in the country.
2. Million Dollar Highway, Colorado
This scenic stretch of U.S. Route 550 offers breathtaking views—but also sheer drops, sharp turns, and no guardrails in many areas. The narrow lanes and unpredictable weather make it especially treacherous in the winter. Despite its name, this highway demands more nerve than dollars.
3. Interstate 95, Connecticut to Florida
While it’s a vital artery for East Coast travel, I-95 is infamous for its heavy traffic, aggressive drivers, and frequent accidents. The stretch through Virginia and North Carolina is particularly notorious for speeding and reckless driving. Congestion and construction zones further heighten the risk.
4. Route 2, Montana
Known as “The Hi-Line,” Route 2 spans hundreds of miles of rural Montana, with limited cellphone service and sparse emergency support. Wildlife crossings are a constant hazard, especially at dawn and dusk. The isolation means that any accident or car trouble can leave drivers stranded for hours.
5. Interstate 10, Texas
Crossing the wide expanse of West Texas, I-10 is plagued by extreme heat, long stretches of monotony, and reckless truck drivers. Tire blowouts and dehydration are real risks for unprepared travelers. Fatality rates are among the highest for U.S. interstates.
6. Route 191, Utah
Dubbed the “Devil’s Highway,” this route winds through scenic yet dangerous terrain, with steep grades and blind curves. Flash floods and rockslides are common hazards. Its remote location also means limited assistance in emergencies.
7. Tail of the Dragon, Tennessee/North Carolina
This 11-mile stretch of U.S. 129 is famous among motorcycle enthusiasts for its 318 curves, but it’s also a magnet for accidents. The road’s tight twists and blind corners make it unforgiving for inexperienced drivers. Oncoming traffic and wildlife only add to the danger.
8. Highway 99, California
Running through California’s Central Valley, Highway 99 is one of the deadliest highways in the U.S., with a high rate of fatal crashes. Poor road conditions, heavy commercial traffic, and speeding drivers create a hazardous mix. Nighttime travel can be particularly risky.
9. Route 285, New Mexico
Nicknamed “Death Highway,” Route 285 sees frequent accidents due to speeding, drunk driving, and poor visibility. Its proximity to the oilfields means it’s congested with heavy trucks, which add to the danger. Narrow lanes and limited shoulders exacerbate the risks.
10. Interstate 15, Nevada to California
This desert highway, connecting Las Vegas to Los Angeles, is infamous for its high-speed crashes and drowsy drivers. Long stretches of unchanging scenery can lull drivers into complacency. Accidents are frequent, especially on holiday weekends.
11. Blue Ridge Parkway, Virginia/North Carolina
Though stunningly beautiful, this scenic route is full of hairpin turns, foggy conditions, and wildlife crossings. The lack of lighting and guardrails in some areas makes nighttime driving especially dangerous. Tourists unfamiliar with the road often misjudge its hazards.
12. Highway 1, Big Sur, California
While Highway 1 offers jaw-dropping ocean views, it also features narrow lanes, sheer cliffs, and landslide-prone areas. The twists and turns require constant focus, leaving little room for error. During rainy seasons, road closures due to mudslides are common.
13. Route 6, Massachusetts
Cape Cod’s main artery becomes a bottleneck during tourist season, with heavy traffic and frustrated drivers. The road’s curves and intersections are accident hotspots. Frequent pedestrian and cyclist crossings further heighten the risk.
14. Interstate 35, Texas to Minnesota
This major north-south route sees a high number of accidents due to its mix of urban congestion and rural stretches. Poor weather in the Midwest often leads to icy roads and low visibility. Distracted and speeding drivers are a constant problem.
15. Route 17, South Carolina
Running along the East Coast, Route 17 is infamous for its swampy terrain, sharp curves, and wildlife crossings. Flooding during heavy rains makes the road especially treacherous. Poor lighting and high speeds add to the danger.
Driving these routes requires more than a sense of adventure—it demands preparation, vigilance, and respect for their challenges. If you must travel these roads, take every precaution, from checking weather forecasts to ensuring your vehicle is in top condition. When in doubt, consider alternate routes or professional advice to prioritize safety over scenery
