That sounds like a passing lane, we have those too. Those are usually nice although occasionally they are only long enough for 1-2 cars to safely pass. It doesn’t help that slow vehicles seem to often speed up for passing lanes.

But a pull out is just that. It’s a pull out. They are typically very short such that one has to pull in and fully stop. They are often found are on narrow roads in windy coastal, mountain or river canyons where putting in a passing lane is not feasible.
