18 Wheeler Collision Data and Trends
Large truck crashes killed 5,788 people in the United States in 2023, up from 5,625 in 2022, according to the latest federal data. Fatalities involving large trucks accounted for 10 percent of all motor vehicle crash deaths that year. In crashes where the truck driver was at fault, common factors include speeding, distraction, and failure to yield. The Insurance Institute for Highway Safety reports that 67 percent of people killed in large truck crashes in 2023 were occupants of other vehicles, while 16 percent were pedestrians, bicyclists, or motorcyclists. The Federal Motor Carrier Safety Administration's Crash Outcome Data Evaluation System shows that driver-related factors were coded in 87 percent of fatal large-truck crashes. The American Trucking Associations notes that safety technology adoption, including automatic emergency braking and video-based monitoring, has grown among major carriers. The National Highway Traffic Safety Administration's Fatality Analysis Reporting System provides the most current publicly available state-level data on truck crash deaths. NHTSA crash data
Injury crashes involving large trucks resulted in an estimated 116,000 people injured in 2023, according to the latest available police-reported data. The average cost per fatal large-truck crash is estimated at over 3.7 million dollars when medical, property, and productivity losses are combined. The Federal Motor Carrier Safety Administration's Large Truck Crash Causation Study identifies brake problems, road conditions, and performance errors as leading factors. Crash frequency is highest on interstates and rural roads, with nighttime hours showing a disproportionate share of fatal collisions. The American Transportation Research Institute ranks states by truck-involved fatality rates using federal crash data. The Insurance Information Institute publishes annual summaries of property damage and injury costs from truck crashes. IIHS large truck research
Common Causes of 18 Wheeler Collisions
Driver Error and Hours of Service
Driver fatigue remains a leading cause of 18 wheeler collisions, with hours-of-service violations cited in a significant share of fatal crashes. The FMCSA reports that 13 percent of truck drivers involved in fatal crashes were considered fatigued at the time of the crash. Electronic logging devices have improved compliance with driving time limits, but violations still occur. Distraction, including phone use and in-cab entertainment systems, contributes to a rising share of truck crashes. The FMCSA's Compliance, Safety, Accountability program uses roadside inspection and crash data to flag high-risk carriers. FMCSA CSA program
Vehicle Maintenance and Cargo Issues
Brake failures, tire blowouts, and lighting violations are common mechanical factors in 18 wheeler collisions. Federal inspections conducted by the Commercial Vehicle Safety Alliance during International Roadcheck consistently find brake and tire violations as top out-of-service reasons. Improperly secured cargo can cause spills, rollovers, and secondary collisions. The FMCSA's Safety Measurement System tracks carrier compliance with vehicle maintenance rules. Major carriers and leasing companies use telematics and predictive maintenance to reduce mechanical failures. FMCSA safety measurement system
