Most states used to have per-axle weight tests and taxes that reflected that. Most of the carve outs for "light truck" that consumer vehicles were able to sneak through were often implemented as carve outs meaning that the weight taxes are still on the books, the states could reduce or eliminate the carve outs and actually try enforcing those taxes again. I'm still surprised California hasn't tried enforcing weight taxes again given many residential streets even still have weight limits posted but not enforced. I'm not surprised that so far no other state currently has the political willpower to upset consumers like that (or to deal with federal complications against a congressional atmosphere and regulatory capture that thinks such taxes are unfair to inter-state commerce).
