Doesn't matter if you can "see the road" or not. When the road center-line indicates "no passing" there's a reason for it. Most of the time the reason has something to do with the environs you're driving through.
We have roads like this. Clear view for ample time to pass in a car/truck. For sure ample time to pass on a bike. The lanes are marked "no passing" because there's a good chance of deer, elk, livestock on the road, bicycles, pedestrians, farm equipment.
When they put a solid line on the highway it means "no passing." That's the
LAW, not a negotiable option left to your "eminent judgment."
When the second (following) rider gets off his bike and confronts the truck driver, that's viewed legally as either "Harassment" (Class C Misdemeanor), or "Menacing" (Class A Misdemeanor). If the rider / driver come into physical contact w/ each other it becomes "Assault" -- although the truck driver is already guilty of Vehicular Assault.

Here's the way the DA works: File charges sufficient to arrest, indict, arraign. Then review the case and enter "multiple pleading" -- filing several and various charges according to what the DA thinks he can prove at trial.
Jury may acquit on some of the charges and convict on some others. Legally, it's sort of like a Chinese buffet.
We, as motorcyclists, need to appreciate that aggressive driving infuriates lots of drivers. And for the record, I concede that I've flipped off my share of drivers -- full leathers on a black, dress Harley. Not good for the PR, but it seemed like a good idea at the time.
