I see a lot of trucks these days with differant stickers on the front ot the for instance a white “L” in a green disc. or sometimes a “G” on a green disc.
some have a black “H” on a yellow disc.
Or a “d” on on a green rectatangle normally o the rear doors of a trailer.
And what did the “SUPER” sign mean on the front of a Scania ( i have one only cos i think it looks cool) sad i know…
