alt Hacker NewsAh thanks! So a design/operation flaw of the scales! I didn't realize they were run/monitored so incompetently, where concepts like "make sure the truck is actually on the scale" were ignored. But, I'm in no way surprised! That's governing bodies for ya!
Overloading is for trucks what speeding is for cars. They don't really "care" beyond revenue as long as you're not absurd about it. The rules were never written to be fully enforced.
Once you understand this the whole system makes sense.
