The Complex World of Commercial Trucks

The commercial truck industry has its own language, complete with acronyms and jargon. As the industry and the words used to describe it continue to evolve, it’s almost impossible to research diagnostic tool capabilities, decipher a wiring diagram… or even read a blog post without coming across something you can’t immediately define. How many of the following terms do you know? 

  1. Aftercooler
  2. B50
  3. Cheater bar
  4. Pintle hook
  5. Tier 4
  6.  VGT
  7.  Wiggle wagon

If you don’t know all of these terms, you’re not alone. But you can bet someone does. Would you know what they meant when they used them?
