Trucking accidents are a significant concern in Wyoming. The combination of vast open spaces, unpredictable weather, and challenging terrain creates hazardous conditions for both commercial truck drivers and passenger vehicles. Wyoming accounted for roughly 21% of large trucks involved in fatal crashes in the US.
Here, we explore five of the most dangerous trucking roads in Wyoming, highlighting the risks they pose to truckers and passenger vehicles and how to stay safer on these roads.
1. US 287
US 287 is a major north-south route spanning the Colorado border to the southern entrance of Yellowstone National Park. While it is a critical corridor for truckers, it is also one of the most dangerous trucking roads in Wyoming. The route is known for its sharp curves, steep grades, and high-altitude passes, which can be particularly challenging during winter when snow, ice, and high winds are common. In addition, US 287 is frequently used by tourists unfamiliar with the road’s hazards, increasing the risk of collisions.
2. Interstate 80
I-80 is Wyoming’s main east-west highway, stretching over 400 miles from the Nebraska to Utah borders. It is heavily trafficked by commercial trucks and is notorious for its high winds, sudden snowstorms, and black ice. Additionally, the long stretches of open road can cause fatigue and lead to accidents. Wyoming Highway Patrol frequently reports accidents involving tractor-trailers on this route, with many incidents resulting in road closures. Drivers should exercise extreme caution, particularly in high-wind areas and during winter weather conditions.
3. Teton Pass – Wyoming Highway 22
Teton Pass, located on Wyoming Highway 22, connects Jackson Hole with eastern Idaho and is a key route for trucks transporting goods in the region. The pass is known for its steep grades, tight hairpin turns, and frequent avalanches, making it a particularly hazardous route for truckers. The steep 10% grade incline and sharp switchbacks are difficult for large trucks to navigate, especially in winter. In fact, trucks over a certain size are prohibited from using the pass during winter months. Teton Pass was closed temporarily following the collapse of a large section of the highway during the Big Fill slide in June of 2024 but was reopened to commuter traffic just a few weeks later. Drivers should be mindful of the challenging conditions when traveling through Teton Pass.
4. US Highway 14A
US Highway 14A runs through the Bighorn Mountains, offering stunning views but also presenting significant dangers for drivers. This road is known for its steep grades, reaching as high as 10% in some sections, and its sharp curves, which can be particularly hazardous for large commercial vehicles. The highway is often covered in snow and ice during the winter months, and its narrow lanes can make passing difficult. Wildlife is also a frequent hazard on this route, with deer and other animals crossing the road unexpectedly. Drivers should be prepared for challenging driving conditions and remain alert to sudden obstacles on this winding mountain route.
5. US Route 191
US Route 191 is another road in Wyoming that poses serious risks. Stretching from the Utah border to Yellowstone National Park, this route passes through some of the state’s most remote areas. US 191 is known for its narrow lanes, steep grades, and limited shoulders, which can be particularly dangerous for large trucks. The route is also prone to strong winds and sudden changes in weather, especially in the Flaming Gorge area. The isolation of this highway means that emergency services may take longer to reach accident sites, further complicating the risks associated with this road. Truckers and passenger car drivers should be cautious, especially in bad weather or at night.
How to Stay Safe on These Dangerous Trucking Routes
While these roads are some of the most dangerous trucking routes in Wyoming, there are steps that both commercial truckers and passenger car drivers can take to stay safe.
Tips For Commercial Truckers
Check Weather Conditions:
Before hitting the road, always check the weather forecast for the entire route. Wyoming weather can change rapidly, so we recommend being prepared for anything.
Proper Vehicle Maintenance:
Ensure your truck is well-maintained and ready for the challenges of Wyoming’s most dangerous roads. This includes checking the brakes, tires, and other critical systems before starting your journey.
Adhere to Speed Limits:
Wyoming has many roads with long, remote stretches that appear safe to travel at high speeds. However, the terrain and weather conditions can change quickly, so adhering to posted speed limits is essential, especially on steep grades and sharp curves.
Follow Road Signs:
Pay attention to signs indicating steep grades, sharp curves, or areas prone to avalanches and wildlife crossings.
Tips For Passenger Cars
Check Weather Conditions:
Before hitting the road, check the weather forecast for your entire route. Wyoming weather can change rapidly, so we recommend being prepared for anything.
Keep a Safe Distance:
Always maintain a safe following distance when driving near large trucks to allow for sudden stops or changes in traffic flow.
Avoid Blind Spots:
Avoid lingering in a truck’s blind spots, especially when passing or driving alongside them on narrow, winding roads.
Be Cautious During Overtaking:
When passing a large truck or another vehicle, do so quickly and safely. Give yourself plenty of room to pass and check that the road ahead is clear before attempting to overtake another vehicle.
