Trucking Safety

British Columbia Highway 5 — the Coquihalla Highway — has a reputation among commercial drivers that is earned every winter. The 315-kilometre corridor from Hope to Kamloops climbs to 1,244 metres (4,081 feet) at the Coquihalla Summit, receives some of the heaviest snowfall of any highway in Canada, and closes multiple times each winter for avalanche control or storm-related hazards.

It is also the most important freight artery between the Port of Vancouver and the BC Interior. When the Coquihalla shuts down, the supply chain for much of western Canada feels it.

There are dangerous roads, and then there is Alberta Highway 63.

For decades, the 465-kilometre corridor between Edmonton and Fort McMurray carried a grim distinction: one of the highest per-kilometre fatality rates of any Canadian highway. The road became so notorious that provincial politicians, safety advocates, and the families of accident victims campaigned for years under the banner of “Twinning 63” — arguing that the single-lane highway was a preventable killer.

For commercial truck drivers, no single stretch of US interstate commands more respect — or fear — than the 150 miles of Interstate 70 between Denver and Grand Junction, Colorado. Combining extreme elevation, sustained steep grades, avalanche terrain, mandatory chain laws, and weather that can change from clear to whiteout in minutes, this corridor is responsible for a disproportionate share of serious commercial vehicle accidents in North America.

If you are dispatching or driving freight through Colorado, this guide is essential reading.

Interstate 80 is the northern transcontinental freight corridor — 2,899 miles of rolling plains, high desert, mountain passes, and urban sprawl from San Francisco to the New York metro. Most of it is manageable. Two segments are not.

Donner Pass in California’s Sierra Nevada and Sherman Hill near Laramie, Wyoming are separated by nearly 500 miles of Nevada and Utah desert, but they share a common identity: they are the most dangerous truck segments on I-80, and among the most dangerous on any US interstate.

Interstate 26 runs approximately 220 miles from I-40 in Asheville, North Carolina southeast through Spartanburg, Columbia, and the South Carolina Lowcountry to Charleston on the coast. It is a major freight corridor connecting the Southeast’s interior to the Port of Charleston — one of the busiest container ports on the East Coast — and carries substantial commercial vehicle traffic year-round.

Between 2000 and 2010, I-26 in South Carolina recorded 286 accidents that claimed 325 lives — a fatality rate that placed it among the most dangerous interstates in the Southeast. The causes were specific, structural, and in many cases preventable.

If I-70 through the Rockies is North America’s most physically dangerous freight corridor, then I-95 through the Northeast Corridor is its most psychologically punishing. The approximately 450-mile stretch from Washington, DC to Boston passes through the densest concentration of population, traffic, toll infrastructure, and aggressive drivers anywhere on the continent. For commercial truckers, running the Northeast Corridor means navigating a continuous gauntlet of merging traffic, narrow lanes, low-clearance bridges, construction zones, and toll plazas — often in stop-and-go conditions that last for hours.

Interstate 5 over the Grapevine — the common name for the Tejon Pass crossing of the Tehachapi Mountains between Los Angeles and Bakersfield — is the single most important and most frequently disrupted freight link in California. Nearly all truck traffic between the Los Angeles Basin and the Central Valley, Sacramento, and the Pacific Northwest must cross this pass. When it closes, and it closes often, the economic impact is measured in tens of millions of dollars per day.

The James W. Dalton Highway is in a category by itself. At 414 miles from the Elliott Highway junction north of Fairbanks to Deadhorse at Prudhoe Bay on the Arctic Ocean, it is the northernmost road in Alaska’s highway system, one of the most remote freight corridors on the continent, and the only surface route supplying the Trans-Alaska Pipeline infrastructure and the oil fields of the North Slope.

For commercial drivers, the Dalton is not a highway in the conventional sense. It is an industrial supply road built to serve the pipeline, and it operates under conditions that have no parallel anywhere else in the lower 48 states.

California State Route 138 connects Palmdale and the Antelope Valley to Interstate 15 near Phelan, running approximately 60 miles through the high desert of San Bernardino County. It is a two-lane highway — undivided, with no median, minimal shoulders, and narrow lanes that leave virtually no margin between opposing traffic streams. It has been called “Blood Alley” by locals and emergency responders for decades, and the name was earned.

What Makes CA-138 Dangerous

The danger on Route 138 is structural. The road was built when traffic volumes were a fraction of what they are today, and it has not been significantly upgraded since. The result is a highway that handles modern traffic volumes at modern speeds on a physical design that belongs to a different era.

US Highway 550 between Ouray and Silverton, Colorado has a name that sounds glamorous — the Million Dollar Highway — and a reputation that is anything but. The 25-mile stretch of two-lane mountain road climbs to over 11,000 feet, carves across sheer cliff faces with no guardrails and no shoulder, and in winter becomes one of the most unforgiving stretches of pavement open to commercial vehicles in North America.

For truck drivers, this road demands a level of preparation and respect normally reserved for major alpine passes. It is not a shortcut. It is not a route to run casually.
