Overloading trucks?

Hello truck driver I have a fundamental question. What about the overload in the forwarding industry? Among the camper drivers seems to be the opinion that all trucks pass over loaded through the country. I am of the opposite opinion, the controls are sharp and the penalties are high. The shipper also seems to be partly responsible. I drove myself over 30 years ago in this trade, since was checked quite often. That there is also outlier is already kl ar, but not the rule. Or am I wrong? Greetings Dieter
