Semi-trucks are the backbone of the American transportation industry, transporting everything from groceries to construction equipment nationwide. While these large vehicles are standard on highways, there’s much more to them than meets the eye.
The reason why 18-wheelers are called semi-trucks is because they consist of two parts: the tractor (the front part with the engine) and the trailer (the cargo section), which are not entirely connected, hence the term “semi.”
In this post, we’ll explore five interesting facts about semi-trucks that you might not know.
- Semi-Trucks Can Weigh Up to 80,000 Pounds
A fully loaded semi-truck can weigh as much as 80,000 pounds, about 40 tons. This weight includes both the truck itself and the cargo it carries. To put this into perspective, the average passenger car weighs around 3,000 pounds. Because of their heavy weight, semi-trucks are regulated by strict weight limits and are subject to weigh stations along highways to ensure they aren’t overloaded.
Overloading can cause wear and tear on roadways and make it difficult for truck drivers to maneuver their vehicles safely. It’s also one of the factors that can contribute to accidents, as the truck’s increased mass makes it harder to stop in emergencies.
- The Average Semi-Truck Can Travel Over 100,000 Miles a Year
Semi-trucks are designed to be workhorses, and many truck drivers log over 100,000 miles each year. It is nearly four times the average miles a typical car drives yearly. The extensive use of semi-trucks is a significant reason for their design focus on durability. With the proper maintenance and care, they can last for several hundred thousand miles.
Fleet operators and drivers rely on regular maintenance of their vehicles to ensure that they run optimally. However, trucks are likely to travel vast distances without being serviced, which increases the possibility of accidents through mechanical failure or driver fatigue. It’s essential to maintain vehicle conditions and driver health to prevent road crashes.
- Semi-Trucks Are More Fuel Efficient
Despite their size and weight, modern semi-trucks are becoming more fuel-efficient. Newer trucks have advanced engines, aerodynamic designs, and energy-saving technologies that help reduce fuel consumption.
For example, features like side skirts, which reduce drag, and more efficient engines can help trucks achieve better miles per gallon (MPG) than older models.
It has a great impact on reducing trucking companies’ operating costs and the industry’s environmental footprint. It also reduces accidents caused by sudden truck breakdowns due to fuel inefficiencies or engine malfunctions.
- Semi-Trucks Can Take Longer to Stop
A fully loaded semi-truck can take up to 40% longer to stop than a passenger vehicle traveling at the same speed. Due to their massive weight, when a truck driver applies the brakes, it takes more time and distance for the truck to come to a complete stop.
This is why truck drivers must maintain a safe distance from vehicles in front of them, especially when driving in adverse weather conditions or during high traffic.
Additionally, braking systems are constantly being upgraded with new technologies like automatic emergency braking to help prevent collisions and improve stopping times.
- Semi-Trucks Are Equipped With Multiple Types of Tires
A semi-truck uses 18 wheels, but those wheels have different types of tires designed for specific functions. The tires on the front of the truck (the steer tires) are for precise handling and stability. The tires on the back of the truck (the drive tires) are for traction and power to push the truck forward.
The trailer tires carry a large portion of the cargo’s weight. They must be in top condition to prevent blowouts and ensure safe, efficient operation. Tire maintenance is a critical part of truck safety and accident prevention.
Conclusion
Semi-trucks are not just a mode of transport; they are complex machines designed for efficiency, safety, and durability. Whether you’re a driver, a trucking enthusiast, or just someone who wants to learn more about these massive vehicles, understanding the facts about semi-trucks can help you know their crucial role in the economy and road safety.
