Commercial truck drivers die significantly earlier than the general population. The median age of death for unionized U.S. truck drivers is about 61 years, compared to 73 for men nationally, a gap of roughly 12 years. Data from the Owner-Operator Independent Drivers Association puts the number even lower, at 55.7 years for its members. The causes aren’t mysterious: the job itself creates a near-perfect storm of health risks that compound over a career.
Obesity and Diabetes Hit Drivers Hard
The most fundamental health problem in trucking is metabolic. A Federal Motor Carrier Safety Administration survey found that 69% of long-haul truck drivers are obese, compared to 31% of the general population. Diabetes rates are double the national average: 14% of drivers versus 7% of all adults.
The reasons are structural. Drivers spend 11 or more hours a day seated, often with no opportunity for physical activity. Meals come from truck stops and fast food restaurants along interstate highways. There’s little time or space to prepare food in a cab, and healthy options at truck stops remain limited despite recent improvements. Over months and years, this combination of extreme sedentary behavior and poor nutrition drives weight gain that becomes very difficult to reverse while still working the job.
Heart Disease Starts With High Blood Pressure
About 34% of professional drivers worldwide have high blood pressure, and in some regions the number exceeds 50%. That rate is substantially higher than the general adult population. High blood pressure is the single biggest risk factor for heart attack and stroke, and it’s largely driven by the same obesity, poor diet, and physical inactivity that define the trucking lifestyle.
Federal regulations technically screen for this. Drivers with blood pressure at or above 180/110 can’t hold a medical certificate at all, and those with moderately high readings get shorter certification periods. But these thresholds are generous. A driver can maintain certification with blood pressure up to 140/90, a level that still carries elevated cardiovascular risk over decades. The system catches extreme cases while allowing chronic, slowly damaging hypertension to persist.
Sleep Apnea Goes Widely Untreated
Between 15% and 30% of North American commercial drivers are estimated to have obstructive sleep apnea, a condition where the airway repeatedly collapses during sleep, causing the person to stop breathing for seconds at a time throughout the night. The primary risk factor is obesity, and since nearly 7 in 10 truck drivers are obese, the connection is direct. Among drivers with a BMI over 32, more than 75% have the condition.
Sleep apnea doesn’t just cause daytime drowsiness. Left untreated, it raises the risk of high blood pressure, heart attack, stroke, and type 2 diabetes. It also makes existing cardiovascular disease worse. Many drivers avoid diagnosis because a positive result can complicate their medical certification or require them to use a breathing machine in the cab, which some see as a career threat. The result is a massive population of workers whose sleep is fragmented night after night, accelerating damage to the heart and metabolic system for years.
The safety consequences are immediate too. Drivers with sleep apnea have a crash risk two to eleven times higher than those without it, and up to 30% of commercial vehicle crashes involve driver sleepiness.
Diesel Exhaust Is a Chronic Poison
Truck drivers breathe diesel exhaust daily, and the health effects are serious. California’s Office of Environmental Health Hazard Assessment, after reviewing more than 30 studies of workers exposed to diesel equipment, found strong evidence that long-term occupational exposure increases lung cancer risk. The agency considers diesel exhaust particles the highest cancer risk of any toxic air contaminant it has evaluated.
Beyond cancer, diesel particulate matter causes chronic lung inflammation. This worsens asthma, contributes to emphysema, and puts additional strain on the cardiovascular system. Drivers aren’t just exposed during fueling or loading. Sitting in traffic, idling at docks, and driving behind other diesel vehicles all contribute to cumulative inhalation over a career that may span 20 or 30 years.
Depression and Isolation Compound Everything
Long-haul trucking is one of the most isolating jobs in the modern economy. Drivers spend days or weeks away from family, eat alone, sleep in their cabs, and have minimal social contact beyond brief interactions at loading docks and truck stops. A 2020 study found that 44% of long-haul truck drivers reported symptoms of depression in the previous 12 months.
The predictors are revealing. Drivers with severe work-related stress were nearly four times more likely to have depressive symptoms. Those with broken sleep patterns were five times more likely. The industry’s defining characteristics, long hours, irregular schedules, extreme time pressure, and low autonomy, are essentially a checklist of known risk factors for mental illness. Depression doesn’t just reduce quality of life. It makes people less likely to exercise, more likely to eat poorly, more likely to smoke, and less likely to seek medical care. It accelerates every other health problem on this list.
Healthcare Access Is Nearly Impossible on the Road
Even drivers who recognize they need medical attention face enormous barriers to getting it. A long-haul driver covering routes across multiple states can’t easily establish a relationship with a primary care physician. Appointments require being in a specific city on a specific day, which conflicts with delivery schedules that change weekly. Missing a load means losing income, and for owner-operators, it can mean defaulting on truck payments.
The result is that preventive care barely exists for many drivers. Conditions that would be caught early in a routine office visit, prediabetes, rising blood pressure, early signs of heart disease, go undetected until they become emergencies. The biennial DOT physical required for medical certification checks a limited set of markers and isn’t a substitute for comprehensive primary care. Drivers who do seek care often end up in emergency rooms, which treat acute problems but don’t manage chronic disease.
Crash Fatalities Add to the Toll
In 2023, 709 truck occupants died in large truck crashes. Nearly half of those deaths involved rollovers. Loaded tractor-trailers need 20% to 40% more stopping distance than cars, and that gap widens on wet roads or with worn brakes. Federal regulations allow drivers to operate for up to 11 consecutive hours, and surveys show many drivers exceed even that limit.
Fatigue, sleep apnea, and time pressure create a dangerous feedback loop. A driver who slept poorly due to untreated sleep apnea, who is behind schedule due to loading delays, and who faces financial penalties for late delivery is exactly the driver most likely to push through exhaustion. Crash fatalities are a relatively small fraction of total driver deaths compared to chronic disease, but they represent the most visible and immediate way the job kills.
Why the Problems Persist
The trucking industry’s health crisis isn’t a secret. Federal officials have publicly cited the 16-year life expectancy gap, and researchers have documented every risk factor in detail. But the economics of trucking work against solutions. Drivers are paid by the mile or the load, not the hour, which creates relentless pressure to keep moving. Stopping for exercise, cooking healthy meals, or attending medical appointments directly reduces income.
The workforce skews toward people with fewer economic alternatives, which means many drivers accept health tradeoffs they might not otherwise make. Owner-operators often carry minimal health insurance. Company drivers may have coverage but lack the schedule flexibility to use it. And the physical design of the job, sitting in a vibrating cab for 11 hours, breathing diesel particulates, eating what’s available at highway exits, hasn’t fundamentally changed in decades despite widespread awareness of the consequences.
