It's a very different mentality here in the US vs Europe in how they treat terrain and closures. In the US, they rope off and bamboo any and every little potential hazard it seems like, whereas it's the opposite in France, Switzerland, etc. Here in CO, where everything is faceted, wind affected, poorly bonded, and all around just kind of deadly, I wouldn't ignore a Danger!! sign and duck a rope into uncontrolled terrain, particularly alone or without the proper gear and training because it would be a "reasonable" expectation that I could die.
I don't know if/what the signs you're referring to are boundary signs and don't necessarily indicate a huge leap in immediate danger, or if those signs are there specifically because the terrain you're then entering is problematic for any number of reasons, or if they're conducting control work with explosives. Where I work, there are temtping, permanent closure chutes known as the 7 sisters. Anyone can ski them I think after June 1....or maybe it's later, don't hold me to it, but before then there can be avalauncher rounds or hand charges from a chopper at ANY TIME. Those closures aren't there so patrol can squirrel it away (in fact that's an auto firing offense and enforced) or whatever, they're there because you can fucking die any number of ways, and because you could trigger a massive slide on top of an open, busy roadway.
All that's just to say that there are.....uhh......"ropes you're allowed to duck" (and I mean you're not allowed to but a patroller probably won't be a dick if he busts you, particularly if you don't seem like some fucking Chad with a deathwish.) Then, there's ropes that under no circumstances should you duck. The 7 sisters are a good example (TERRIFYING terrain trap bench deads at the pass, there's a heavily traveled mountain pass road right below the paths,NE aspect, above and near treeline, gnarly dense trees, deepy gully walls in places, lots of nice nooks and crannies to die alone in agonizing asphyxiation, etc.). I don't know which kind of rope you're ducking, but scarier, I'm not convinced YOU know what rope you're ducking.
My advice is to do research on where you're skiing. check the avy reports for the area, read accident reports, make good plans, get gear, get friends with gear and experience and training, and then go live a rad mountain lifestyle with your bros.
