Reply to comment by PlayfulParamedic2626 in Tesla Semi 500-Mile Trip Video Shows Truck May Have Had a Lower GVW Than 81,000 Lb by Ssider69
The vehicle weight limit is legally allowed to be higher for ev trucks I believe.

This guy's YT video says the Semi has special permission to go to 82k pounds.

Any EV truck has an 82k instead of 80k limit

Why? If EV trucks are allowed to do that then why give the limit to diesel trucks

The extra 2k is a fuel allowance, which an electric doesn’t need.

Yes they do. The battery packs.

I suppose the idea is that diesel trucks can get weighed with a near-empty tank, meaning they end up on the road with their weighed weight + fuel on top. EV trucks cannot remove the battery during weighing.

They are trying to throw a carrot to the electric truck because the batteries are so heavy. An extra 2000lbs isn't going to make much difference to the roads, but can offset some of the extra weight of the heavy battery packs of the electric semis.

Actually it does make a big difference. Road damage increases proportional to the 4th power of GVW.
Some simple math shows that cars do just a couple % of damage, whereas trucks do the vast majority.

Trucks do the vast majority of damage, but a difference of ~2.5%, which is about the weight of full fuel tanks isn't going to change that amount by an appreciable amount.
Especially since many states and provinces actually allow more than the federal standard, provided the axle count/configuration meets their rules. Michigan goes up to 164 000lbs with 11 axles and Quebec/Ontario are similar.
