Where and when are u allowed to go 4x4ing. Wanting to take out my xterra. But not sure if your are allowed here.

Also roads marked on your maps app are also good to ride on, it's a good rule of thumb if you're unsure. They pop up on my phone only when zoomed in enough

You can just stay on the roads

Stay on the roads and you all good.

Yes you are allowed. I've been there in the day time and all the way up to 11pm.
