There's a lot the average driver doesn't know about the trucks they pass on the highway. For instance, the spikes on truck wheels are often made of plastic, and the word doesn't indicate half a vehicle. But one of the most inscrutable aspects of big rig culture is trucker slang.
If you've ever eavesdropped on a CB radio frequency, you know that truck drivers communicate in their own language. Using special lingo, truckers discuss everything from hazards on the road to the best spots for coffee. Even if you only drive vehicles with four wheels, you can still have fun using these pieces of truck driver slang on your next road trip.
