So, you’re cruising down the highway, and you spot one of those massive rigs with 18 wheels. But have you ever stopped to wonder what these behemoths are actually called? Well, buckle up, because we’re about to take a journey into the world of trucking terminology!
Let’s start with the basics: the term “18-wheeler” itself. This nickname comes from the number of wheels these trucks typically have: two wheels on the front axle of the tractor and eight wheels on each of the two rear axles of the trailer, totaling up to 18 wheels in all. Simple enough, right?
But wait, there’s more! Depending on where you are in the country or who you’re talking to, you might hear these trucks referred to by a variety of other names. One common alternative is “semi-truck” or simply “semi.” This term comes from the fact that these trucks typically haul semi-trailers, which are trailers with only one set of wheels at the rear, rather than the full complement found on trailers pulled by trains.
Now, let’s get a little more regional. In the southern United States, you might hear people refer to 18-wheelers as “big rigs” or “tractor-trailers.” These terms evoke images of the sprawling highways and open roads of the South, where these trucks are a common sight.
Head up north, and you might hear them called “18-wheelers” like everywhere else, but you might also hear the term “articulated lorry” thrown around. This term has its roots in British English but has found its way into American trucking lexicon as well. It’s a fancy way of saying “a big truck with a bendy part in the middle.”
Now, let’s talk about the kings of the road: “road trains.” Found primarily in Australia, these massive convoys consist of a prime mover pulling multiple trailers behind it, sometimes numbering in the double digits! It’s like a parade of trucks, stretching as far as the eye can see.
And speaking of eye-catching, have you ever seen one of those gleaming chrome monsters cruising down the road? Those are often referred to as “big rigs” or “18-wheelers,” but truck enthusiasts might affectionately call them “iron horses.” These beasts of burden command respect on the road and evoke a sense of awe in anyone who sees them.
