The article does say that 31% of those surveyed didn't have the training, so presumably, the majority of departments do have the training. Given the number of poor rural volunteer departments in the US that struggle with funding, I would assume that 31% probably overlaps with the set that are struggling in general.
Also raises the question of what share of EVs are in poor rural jurisdictions. EVs are more popular in urban areas that have charging infrastructure and shorter-range trips.
I see EVs in rural California all the time. If an EV gets into an accident on its way to a national park the closest fire department is going to respond.
