A fully loaded semi-truck can legally weigh up to 80,000 pounds on interstate highways, but the exact weight varies depending on the type of truck and cargo. Truck weight is an important part of truck crashes because the massive size difference between trucks and passenger vehicles often leads to severe injuries.
Knowing about truck weights helps explain why these crashes are so devastating and why specialized legal representation can help you get the most from your accident claim. Our Indianapolis truck accident lawyers explain.
Each Part is Heavier than You May Think
Semi-trucks have a tractor and a semi-permanent trailer. The tractor unit typically weighs between 15,000 and 18,000 pounds. The exact weight depends on the make and model. Getting into a crash with this part will still generate more force than the average crash.
The trailer portion of a semi-truck adds considerable weight to the overall vehicle, typically ranging from 10,000 to 15,000 pounds when empty. The maximum cargo weight a semi-truck can legally haul depends on various factors, including the number of axles and each state’s specific regulations.
The Federal Motor Carrier Safety Administration (FMCSA) permits a maximum gross vehicle weight of 80,000 pounds on interstate highways, which includes the combined weight of the tractor, trailer, and cargo. In rare cases, a carrier can get a permit to exceed these limits.
Impact of Weight on Truck Accidents
The physics of truck accidents often result in catastrophic injuries due to the tremendous force generated by the truck’s mass. Simple physics tells us that the force of a crash is caused by the mass of the vehicle and its acceleration.
Even a relatively low-speed collision with a heavy truck can have serious consequences for smaller vehicle occupants. Furthermore, the difference between the weight of the semi-truck and the weight of the passenger vehicle means the smaller vehicle absorbs more force.

The Attention It Deserves
Legal Weight Limits and Regulations
Overweight trucks pose significant safety risks and can face substantial fines and penalties for non-compliance. Exceeding these limits can affect their handling, braking distance, and overall safety performance, potentially contributing to serious accidents.
Federal regulations establish specific weight limits for commercial trucks to ensure road safety and prevent infrastructure damage. For instance, the federal bridge formula determines the maximum allowable weight based on the number of axles and the distance between them to distribute the load properly.
State regulations may vary from federal limits, particularly on state and local roads where different weight restrictions might apply. Indiana follows federal guidelines for interstate highways but may have specific requirements for state roads and bridges.
Special Weight Permits and Oversized Loads
A semi-truck usually cannot weigh over 80,000 pounds, but some carriers can obtain special permits to transport heavier loads on specific routes. These oversized/overweight permits have strict requirements, including designated travel times, specific route restrictions, and additional safety equipment such as escort vehicles and warning signs.
The requirements for special weight permits vary significantly based on the total weight and dimensions of the transported load. Accidents involving trucks operating under special permits increase the complexity of the case.
Weight-Related Safety Requirements
Commercial drivers must understand their vehicle’s weight limitations and maintain proper load distribution. Professional truck drivers receive specific training on weight management, load securing, and safety procedures related to operating heavy vehicles.
Regular weigh station stops help trucks maintain safe operating weights throughout their journey. These checkpoints identify and correct potential weight-related violations before they lead to accidents.
Safety equipment requirements, including enhanced braking systems and additional safety features, become more stringent as truck weights increase. These requirements help mitigate the inherent risks of such heavy vehicles on public roads.
Semi-Truck Weight Violations as Evidence of Negligence
When trucking companies or drivers violate weight-related safety requirements, these violations can be powerful evidence in your accident claim. Each violation represents a choice to prioritize profit over safety, potentially putting everyone on the road at risk of serious injury or death.
Evidence of overloading or improper weight distribution can help establish liability in your truck accident case. Our team carefully reviews weight station records, loading documentation, and driver logs to identify any violations that may have contributed to your accident.
For example, since heavier trucks require more distance to slow down, a truck in an accident could not stop in time because it was overloaded beyond what was legally allowed. A lawyer may work with accident reconstruction specialists who can demonstrate how weight-related violations affected the truck’s performance and contributed to a crash.
Learn if Semi-Truck Weight is a Factor in Your Crash
If you’ve been involved in an accident with a semi-truck, your lawyer will want to know how much the semi-truck weighed at the time of the crash. They can get this information from the shipper, weigh station logs, and other documentation.
