Overweight and overloaded trucks pose significant dangers on highways, including damage to infrastructure and the threat of serious or deadly accidents. Federal and state regulations are in place to minimize risks, but when these laws are violated, drivers, employers, loaders and others who are negligent may be held responsible for resulting injuries.

The Federal Motor Carrier Safety Administration (FMCSA) sets a gross vehicle weight limit of 80,000 pounds on interstate highways. In addition, there are axle weight limits of 20,000 pounds per single axle and 34,000 pounds per tandem axle (two axles close together). Further restrictions apply depending on spacing between axles to prevent overly concentrated loads.

Trucks that are overweight or overloaded can cause accidents due to any or all of the following:

1. Reduced vehicle control and braking — Overweight trucks require longer distances to stop due to the increased momentum inherent in their mass. The excess weight strains braking components, leading to brake fade or failure. As a result, an overloaded truck is less capable of responding to sudden emergencies, lane changes, or stops, increasing the risk of collisions.

2. Increased risk of mechanical failures — Exceeding manufacturer-specified weight capacities accelerates wear-and-tear on critical vehicle components. Tires overheating, premature suspension breakdowns, and axle or frame failures are common consequences. These malfunctions may cause tire blowouts, loss of steering control, or catastrophic breakdowns.

3. More severe accidents — The immense kinetic energy of an overloaded vehicle makes any accident potentially more devastating. Collisions involving heavy trucks result in more significant damage to passenger vehicles and infrastructure and raise the likelihood of fatalities or severe injuries.

4. High center of gravity — Improperly loaded or overweight trucks often have unbalanced weight distribution that make rollovers more likely, especially on curves or during evasive maneuvers.

Overweight trucks exert excessive pressure on roads, bridges, and overpasses, leading to accelerated wear, cracks, potholes, and, in extreme cases, structural failures. Degraded infrastructure increases the danger for others on the roads. When a collision occurs with a smaller vehicle, its drivers and passengers are more likely to suffer serious or catastrophic injuries.

Multiple parties can be held liable for accidents involving overweight or overloaded trucks, depending on their causative roles. Defendants can include the following:

1. Truck driver — A driver is responsible for conducting a pre-trip inspection, knowing the vehicle’s weight and making sure the cargo is properly secured and balanced. If a driver knowingly operates a truck exceeding legal limits, they may be liable for resulting accidents.

2. Trucking company or carrier — Companies must ensure compliance with federal and state weight laws. If they encourage or permit violations, such as by demanding unrealistic delivery schedules or ignoring regulations, they may be held directly liable.

3. Shippers and loaders — If third parties such as warehouse staff or contractors improperly load a truck, causing it to be overweight or dangerously unbalanced, they may be liable for resulting accidents.

4. Maintenance providers — If a mechanical failure related to overloading can be traced to negligent maintenance, service providers may also bear liability.

5. Manufacturers — If inaccurate ratings or defective parts contribute to a failure under legal loads, manufacturers may share liability.

An experienced truck accident attorney can investigate potential HOS violations and work to hold the trucking company and other negligent parties responsible. An attorney can help you recover financial compensation not only for your physical injuries but also for related losses such as medical expenses, lost wages and pain and suffering.
