Anyone can see that a semi-truck is a large vehicle. What you may not know is how much these vehicles weigh. Compared to the average passenger vehicle, a semi-truck weighs considerably more, which makes them particularly hazardous when they are involved in crashes and truck accidents.
On average, a commercial truck can weigh:
Before we dive into the facts about semi truck weight, it is important to define two key terms: laden and unladen.
Truck weight is measured in two ways:
The cab or cabin of a semi-truck, also known as a tractor, is the compartment where the truck driver sits. Think of this as the “command center” for the vehicle. Semi-truck cabs vary greatly by design and size, so their weights vary, too. Some have high-end air suspension seating to provide better support for truckers, professional sound systems, and attachment “sleeper cab” sections for resting or sleeping.
In lieu of government standards for truck weight, trucking companies and drivers may give special consideration to any cab alterations that affect total vehicle weight. Any additions to the cab affect how much a truck driver can haul because every single component will add some weight to the truck’s total weight, including a little fan to cool the cab on long drives!
According to JD Power & Associates, the average weight of an unladen semi truck cab is between 10,000 pounds and 25,000 pounds. Variables such as the size of the engine and cab enhancements may affect total weight, too.
The semi-trailer is the freight section of the semi-truck-trailer combination (without the cab). According to JD Power & Associates, the average weight for an unladen 53-foot trailer is approximately 10,000 pounds. The total weight for laden trailers varies by axle. A single-axle trailer can haul up to 20,000 pounds. A double-axle trailer (or a tandem axle) can haul up to 34,000 pounds. These limits include the freight and trailer weight combined.
A combination semi-truck and an unladen trailer can weigh anywhere between 20,000 pounds and 35,000 pounds. A semi-truck and a laden trailer can weigh as much as 80,000 pounds, per federal regulations. According to multiple sources, the industry average is around 50,000 pounds for a semi-truck and trailer combination carrying a load of products, freight, etc.
Gross vehicle weight rating (GVWR) is another way that the total weight of a semi-truck can be evaluated and calculated. This type of weight rating applies to vehicles of different types.
No matter the type of vehicle, though, GVWR considers two elements of weight measurement:
The base curb weight rating of a vehicle using the GVWR scale is useful because this weight is predictable and shouldn’t change once a vehicle is manufactured and road-ready. For example, two MAC trucks of the same year and model should, in theory, have the same GVWR base curb weight, regardless of how those trucks are used or maintained.
Using the GVWR scale, eight weight classes exist among three types of commercial trucks:
Nearly all semi-trucks are considered class 8 trucks once they are loaded with cargo, but some can be class 4, 5, or 6 trucks when not loaded and not attached to a trailer. The classification of a truck is important because it must match the vehicle’s GVWR when it passes an inspection and weighing point, which can be found along most major American highways. The inspection points calculate GVWR with a simple formula: GVWR = trailer capacity + trailer weight. If a trucker reports that they are operating a Class 7 truck but the scales calculate a GVWR of more than 33,000 pounds, then the trucker and trucking company could face fines and other penalties.
Trailers vary in size and weight depending on the haul. Any truck driver will tell you that driving a semi-truck with a tanker trailer carrying natural gas or other chemicals is different than driving a semi-truck with a double-deck trailer transporting cars. It is all about weight and weight distribution, and how these important aspects of hauling freight will change the handling and performance of the semi-truck.
Such discrepancies are particularly important when considering stopping distances. It takes a semi-truck-trailer combination much longer to stop than a standard car due to the massive weight. This remains true even if the trailer is not loaded with cargo.
At 65 miles per hour, the average passenger car can come to a complete stop in roughly 300 feet. In contrast, a fully loaded semi can take more than double that distance to a complete stop. The distance is even longer if the truck driver has to deal with rain, ice, or snow.
The sheer size and weight of semi-trucks make them particularly destructive in accidents. That is why it is vitally important for truck drivers to operate their vehicles with the utmost care and diligence.
Heavier trucks increase the risk of severe injuries or fatalities when they are involved in crashes. According to the Association for the Work Truck Industry (known as the NTEA), an overloaded semi truck, meaning that it exceeds the gross vehicle weight limits and weight distribution regulations, has “dramatic effects” on steering, maneuverability, braking, and acceleration.
If a truck driver, trucking company, subcontractor, freight loader, or another party fails to take reasonable care concerning loading and transporting goods, the drivers and the companies they work for may be held liable for damages in a truck accident lawsuit. An experienced trucking lawyer will understand how to properly investigate a case to uncover any issues with truck weight violations. Having someone who knows the intricacies of truck crash litigation can level the playing field against major trucking companies and their legal teams, who will go to great lengths to limit their liability.
Truck accident cases are complex and often involve multiple liable parties, insurance companies, and intricate trucking laws. To navigate these complexities and ensure that victims receive the compensation they deserve, an experienced truck accident lawyer is essential. Below are some of the reasons why you should hire a trucking accident attorney.
One of the primary challenges in truck accident cases is determining liability. While the driver may have directly caused the accident, claims often involve multiple parties, including different trucking companies, brokers, manufacturers, and others. For example, the trucking company may be liable for their drivers' actions, the truck's manufacturer may be liable for defective parts, and the shipping company or maintenance company may also be held liable for any negligence that caused or contributed to the semi-crash.
Truck accidents often involve multiple victims, such as in multi-car pileups. Each victim deserves their fair compensation, and pursuing an individual claim is necessary. Hiring a truck accident lawyer ensures that victims have their best chance at securing the compensation they deserve.
Another challenge in truck accident cases is dealing with insurance companies. Each liable party will likely be represented by a different insurer, making negotiations difficult and time-consuming. While truck accident victims and their families are seeking full and fair compensation for the damages they have suffered due to negligence, insurance companies are often inclined to offer lowball settlements that are less than a claim might be worth. Without the guidance of a knowledgeable lawyer, victims may be unaware of the full value of their claims. Simply put, victims of truck accidents should prioritize their recovery and leave the back-and-forth with insurance companies to their attorneys.
Trucking laws add another layer of complexity to these cases. The Federal Motor Carrier Safety Administration (FMCSA) regulates the trucking industry, and violations of their regulations can be used as evidence of negligence. An experienced lawyer will have in-depth knowledge of these regulations and will understand how they apply to individual cases, as well as any relevant state and local laws.
Truck accidents often result in severe injuries or fatalities, further complicating the litigation process. The size difference between a car and a semi-truck, combined with high speeds and other factors, frequently leads to catastrophic outcomes. Recovering compensation for these injuries requires collecting extensive evidence and relying on expert testimony. A skilled truck accident lawyer will know where to look for evidence and which experts to consult to build the strongest case possible and maximize compensation.
Fatal truck accidents present their unique challenges. The losses faced by surviving family members are significant, but insurance companies may prioritize their bottom line over fair compensation. Working with a lawyer experienced in handling wrongful death cases is crucial to ensure that the affected family members receive the compensation they deserve.
Comparative fault laws further complicate truck accident cases. California and other states may reduce the proportion of damages based on the victim's responsibility for the accident. Parties involved may attempt to argue that the victim is partially or entirely at fault, potentially reducing the compensation awarded. In these cases, it is vital to consult with an attorney to protect the right to full compensation.
