Kingpin
A kingpin is a crucial connecting piece in commercial trucks that joins the trailer to the tractor (the front part of the truck that contains the engine and driver's cabin). Think of it like a sophisticated hook system that lets truck drivers safely connect and disconnect different trailers. It's a fundamental component that every truck driver needs to understand and work with. When someone mentions "kingpin inspection" or "kingpin maintenance" in their resume, they're talking about safety-related duties that are essential in the trucking industry.
