How does the junction system work?

[Dr.Gonzo1836]

I just got the mission to go to the sierram town and it looks like i have to go through another zone to get there, but I thought each trip was only one way? How does this work? Is it tutorialized eventually?

[Brocktunes!]

Look at the ARC map. One of the exits will be different; you need to drive through that one to get to the next junction.

There wasn't a tutorial unless I missed it, it's kind of just play it and get the hang of it.
So there are some zones that have stable exits and others (dead ends) simply won't let you go in, and then there are those with no gateways out but there is a stable junction door to your destination or vice versa, as far as I can tell the only way to do multiple junctions in one trip is to plan it that way at the planner board otherwise I go to a junction that appears to have a stable junction door but then I have to leave via gateways because I was wrong.

The trip is still one-way, you need to go through other junctions' exits to reach there. A junction exit and a gateway are not the same thing by the way. You may cut your trip short by opening a gateway back to the garage in some junctions as long as you have collected enough kLIM on the way, but this isn't what you want unless you need to get back.

I am currently stuck and cannot exit the stage I am in. Trying to get to Sierram...but after passing through the first area, all I see are yellow markers flashing on the map now and nowhere does the option for a gateway appear. I cannot loot anywhere else, cannot go back, and there is no way to exit the stage.... Not sure if I am missing something or if its a bug...

If your trip involves more than one zone, one of the checkpoints will be open for you to drive through into the next zone, you won't use the normal method of leaving via a gateway until you either open one yourself or reach the final zone where your journey ends.

One way doesn't mean it dead ends (though there are dead ends), it means you can't turn back. So you go junction to junction until you either die or land at a gateway junction and leam via a gateway.
