Truck accidents cause thousands of deaths and injuries in the United States every year. Large trucks were involved in 144,518 crashes reported to FMCSA in 2025, including 3,727 fatal crashes that killed 4,146 people and injured 70,526 more. Those figures are still preliminary and will likely rise as states finish reporting.
In 2024, large trucks were involved in 156,052 reported crashes, with 4,602 deaths and 74,078 injuries. Both years show how deadly truck crashes have been. As reporting for each year finishes, the numbers will shift.
The height of a truck or its design is another factor that may be responsible for some accidents’ severity.
Let us analyze how injuries from truck accidents can become serious. This analysis will provide some understanding of the physical dangers and other things that could influence one’s ability to recover from an accident.
Mass and Momentum Do Most of the Damage
A loaded tractor-trailer can reach 80,000 pounds, twenty or more times the weight of most cars on the road. In a crash, that difference lands almost entirely on the smaller vehicle.
As compared to a passenger vehicle, a loaded truck requires 20% to 40% more stopping distance. Slick roads and unmaintained braking systems make these discrepancies worse.
With both drivers exhibiting identical reaction times, the truck requires substantially more distance to come to a stop.
Underride Turns a Survivable Crash Into a Fatal One
Underride refers to a situation that applies exclusively to crashes involving trucks, as compared to crashes between two regular cars.
In an underride crash, a car slides beneath the back or side of a trailer. The trailer’s frame sits above the car’s bumper and crumple zones, so it can strike the passenger cabin directly and bypass the car’s main safety features.
Federal rules require rear underride guards on most trailers, but there is no federal requirement for side guards, a gap safety advocates have pushed to close.
Cargo Adds a Layer of Risk Unique to Trucks
Cargo adds its own risks. Hazardous loads like fuel or chemicals can spill, burn, or explode after a crash, and loads that are poorly secured can shift in a turn and tip the truck or spill onto the road.
The physical damage is only one aspect of truck accident cases. These cases also bring legal complications that most car accident cases never face.
Liability may involve not only the driver but also several other parties, including the trucking firm, maintenance firm, cargo firm, or the manufacturer of the defective part.
Evidence in a truck crash can disappear quickly, and the trucking company’s own investigators are often on the scene early. A Los Angeles truck accident lawyer will typically move quickly to lock down driver logs, maintenance records, black box data, and inspection history. Those records often decide which party bears responsibility.
The Practical Reality
The danger from truck crashes is often much more severe than car crashes. A crash with a big truck is more likely to be fatal than one between smaller vehicles, largely due to the truck’s weight. Even at slower speeds, large trucks pose more of a danger than most smaller vehicles. Large trucks carry a risk of underride crashes and need longer distances to stop. Poorly secured cargo can shift while driving and throw the truck off balance.
With more parties involved than in a typical car crash, sorting through maintenance and crash reports, driver logbooks, and vehicle records can take longer.

Why are truck accidents more likely to cause serious injuries? Trucks are massive, and their sheer weight and mass can potentially be more devastating to passenger vehicles during crashes.
