Indeed. So while a 4.5 ton vehicle, the Hummer EV, does 25 times as much damage as a 2 ton sedan, a semi truck with 5 tons on each axle does ~625 times as much damage to the road. But 5 tons is not the standard. The federal axel limit is 20,000 pounds, so a fully loaded truck could be doing the same amount of damage to the road as 10,000 sedans. I doubt this is the average axle weight of all semis on the road, though.
