I generally respect truck drivers. But here in the west, loggers are well known as the rudest drivers. They will definitely do everything they can to intimidate other traffic, and they are very good at it. Sounds to me like they were successful with the intimidation of the OP, and I can't say I blame him. They won't hesitate to pass you and cut you off into the ditch. No loss on their part. Damage wouldn't show on a logging truck anyway.
I'm not sure what makes me angrier. Logging drivers, or law enforcement that just looks the other way.
