Transportation incidents are the leading cause of death in the workplace, accounting for 38.2 percent of all occupational fatalities in the United States. In 2024, 1,937 workers died in transportation-related events out of 5,070 total workplace deaths recorded by the Bureau of Labor Statistics. That means roughly two out of every five workers killed on the job died in a crash, collision, or other transportation event.
Why Transportation Tops the List
When people think of dangerous jobs, they picture construction sites or factory floors. But the single deadliest category year after year involves vehicles. Roadway incidents involving cars, trucks, and other motorized land vehicles accounted for 1,146 of those transportation deaths in 2024, a decrease of 8.5 percent from the prior year. The remaining transportation fatalities include incidents involving aircraft, watercraft, rail vehicles, and workers struck by vehicles while on foot near roadways.
The workers most affected aren’t just long-haul truckers. Delivery drivers, sales representatives, home health aides traveling between clients, utility workers, and anyone whose job puts them behind the wheel or near traffic faces this risk. The sheer number of hours American workers spend driving makes this category hard to shrink, even as vehicle safety technology improves.
Other Major Causes of Workplace Death
Falls are the second major killer, particularly in construction. Fall protection violations are the most frequently cited safety standard in OSHA inspections, and fall protection training ranks among the top ten as well. Construction workers face a fatal injury rate of 9.2 deaths per 100,000 full-time workers, and falls from roofs, ladders, and scaffolding drive a large share of those numbers.
Exposure to harmful substances and environments is another significant category, though its full toll is harder to measure. OSHA estimates that chemical exposures alone cause roughly 50,000 worker deaths per year, but most of these are occupational illnesses like cancer or lung disease that develop over years or decades rather than acute injuries counted in annual fatality reports. The BLS census primarily captures sudden traumatic deaths, so chemical-related fatalities are dramatically undercounted in the headline statistics.
Contact with objects and equipment (being struck by falling materials, caught in machinery) and workplace violence round out the remaining major categories.
Industries With the Highest Death Rates
Total death counts and death rates tell different stories. Construction has one of the highest raw counts because it employs millions of people. But agriculture, forestry, fishing, and hunting is far deadlier per worker, with a fatality rate of 20.9 deaths per 100,000 full-time equivalent workers, more than double construction’s rate of 9.2. Workers in these fields face heavy machinery, remote locations with limited emergency access, unpredictable animals, and extreme weather.
Older Workers Face the Greatest Risk
Workers aged 55 to 64 consistently suffer the highest number of fatal workplace injuries of any age group. In 2024, 1,031 workers in that range died on the job, roughly one in five of all workplace fatalities. This pattern has held steady for years: the same age group led in 2020, 2021, 2022, and 2023. The reasons are layered. Older workers are more likely to hold physically demanding jobs they’ve done for decades, their bodies recover less easily from falls or impacts, and age-related changes in vision, balance, and reaction time compound risk in hazardous environments.
Long-Term Trends Are Improving
The 5,070 deaths recorded in 2024 represent a 4 percent drop from 5,283 in 2023. Zooming out further, the improvement is dramatic. Between 1980 and 1995, the occupational injury fatality rate fell 43 percent, from 7.5 to 4.3 deaths per 100,000 workers. That decline continued in the decades since, driven by stronger safety regulations, better equipment design, and more widespread training programs.
Still, progress has plateaued in recent years. Annual totals have hovered around 5,000 to 5,500 since 2020, and transportation incidents have stubbornly remained the top killer despite improvements in vehicle safety. One reason is that the nature of work keeps shifting: the growth of delivery services, gig economy driving, and mobile workforces puts more people on the road for more hours.
The Economic Cost
Workplace fatalities carry an enormous financial toll alongside the human one. CDC research examining occupational injury deaths over a multi-year period found the average cost to society per death was approximately $784,000, factoring in lost productivity, medical expenses, and related costs. Over a six-year study period in the 1990s, the total societal cost reached $33 billion. Adjusted for today’s wages and medical costs, those figures would be substantially higher. These numbers reinforce why prevention spending, from fall protection harnesses to fleet safety programs, pays for itself many times over.
