Ok ,traveling down a two way highway and come upon all the vehicles in your lane stopped with their hazards on, and no one in the on coming lane, would you just automatically just try and pass all the vehicles, or maybe see why everyone was stopped?

I have been in a line up waiting for the road to clear because of an accident, and here comes an idiot driver down the left hand lane thinking he is getting ahead, when stopped and asked why he was doing that, all he could do was say he had to get going.
Would you just start passing all the stopped vehicles, or maybe find out why they were all stopped?
