What it means
The S-852 sign indicates a priority route. It works as a supplementary panel showing the layout along which the priority road continues at an intersection or set of accesses, so you must interpret it together with the main priority sign. It does not create independent priority or replace the obligation to observe other users. It usually appears when the priority route turns, diverts, or does not match the most obvious path. When you see it, identify whether your movement follows that route and act accordingly. In the test they often ask you to read the drawing and not confuse it with a mandatory direction.
