I gave you two reasons, but never said that it was limited only those two. I’m sure that there are places in the US where fireworks are banned purely because of a few whiney ninnies. There are probably other reasons as well. The US is made up of 50 states, each state has many counties and cities. I have no idea why Maine has its fireworks laws; they do have a lot of forests though. I have no idea if they ever get dry; never been there.
Clearly the biggest and most common reason in the US however, is fire danger.
If fireworks are used in a low fire danger area sporadically, because it’s not a traditional fireworks night, fire department can keep up. On the 4th, however, there could be hundreds of fires at once; no fire department could keep up. Like I said, there is no comparison of the fire danger in Britain and much of the US.
