Usually if that over weight, pay fine etc, then continue on. The goal of law is not destroy the roads! Trucks pay proper tax for damage done during normal use. Their has been more than one cveo/LEO that's mentioned this. One truck driver used to hit Louisiana border at 110,000 lbs legal in Texas, 80k max in Louisiana. Pulled out company CC, played fine, continued on his way to warehouse, unloaded, headed back for another load. Fine etc was cheaper than reducing load, and profit etc from contents in load.
More than one way to look at this. If one does find examples of being fined for overweight, one needs to get to fine print to see why.
