Driveways, parking lots, and some merge lanes don't have stop or yield signs. So it's not always marked.
Much more interesting are one lane tunnels or bridges that have a yield sign on both sides. Effectively, people just do fist come first served, but if it's at the same time you have to negotiate who has the right of way.
