LaR, loaded and rolling. Such a joyful noise a dispatcher every did hear outside of wedding night. HA....

I see HAD on the back of trailers. But substitute a black triangle for the 'A'

 

Found elsewhere It means that the trailer has been inspected and certified as being heavy duty to the standards set forth by the auto industry. The trailer must have a minimum number of steel support beams under the wooden floor of the trailer so that a forklift will not bust through (yes this happens). The triangle doesn't literally have any meaning, it's just to easily identify a heavy duty trailer at a glance

 

HHG= HEAVY HAUL GROCERY. A new permit authorized by Donald Trump to allow Walmart Drivers to haul up to 90,000 Gross, in order to restock the shelves quicker!
