When it comes to the big rigs that traverse our highways, they are most commonly referred to as semi-trucks. But why is a big truck called a semi?
The term “semi” comes from the fact that these large trucks actually only have one trailer connected behind them. This is in contrast to other types of trucks, such as double trailers or articulated lorries, which have two or more trailers connected together. Thus, the single trailer qualifies it as a “semi” truck.
When you look at a semi-truck, you will also notice that it has two rear axles and one front axle.
This helps distribute the weight of the trailer and its cargo more evenly across all three axles. This helps prevent wear and tear on the tires and suspension systems, making it safer for highway travel.
In addition to safety benefits, this type of truck design is also beneficial for fuel efficiency. By spreading out the weight of the cargo more evenly across all three axles, less fuel is required to get from point A to point B. This makes them much more efficient than other types of large trucks with multiple trailers attached.
In conclusion, semi-trucks are given their name due to the fact that they only have one trailer attached behind them. This single trailer design provides safety benefits on the highway as well as improved fuel efficiency over other types of large trucks with multiple trailers attached.
