That's quite a bold statement, especially since the driver should be responsible for the safety of their passengers.
I don't know the specifics of their operation, but my guess is that there's someone who watches the weather and communicates with the drivers. There's no way they ask each and every driver to look at radar and make weather forecasts while driving a 30 something passenger bus / boat. The drivers should be focused on driving and leading a tour.
Good point, I didn't think of that. There had to have been a breakdown in communication somewhere that led to the driver being caught off guard, especially with the storm being warned for half an hour. I just got back from Brason on Sunday, and it's very hard for me to even comprehend that an accident of this magnitude could happen in such a wonderful place. I hope they find out what happened so situations like this one do not occur in the future.
