You were replying to a comment saying "studies have shown lower speed limits reduce accidents" with something along the lines of "but who cares if I go 10 over the limit, trucks have more mass and are more dangerous at the same speed". I can't even see your original comment since it was flagged, presumably for being total nonsense.
This is not one vs the other, multiple things can be true. Trucks are individually more dangerous than cars. There are far more cars than trucks on basically every road basically everywhere. Cars are driven by any idiot in all kinds of situations, trucks are driven by professionals during their regulated working hours.
