Which traffic sign gives right of way?

Your answer is correct because traffic sign 1 is the one that gives right of way. This sign indicates a junction where you have the priority or right of way over traffic coming from other directions.

Traffic sign 2 is a warning sign that there is a priority road intersection ahead, but it does not itself grant right of way—it alerts you to a crossing where priority rules apply. Traffic sign 3 is a route or direction number sign and does not affect right of way.

In German traffic rules, priority is often communicated by signs that clearly indicate who must yield. A triangular warning sign (like signs 1 and 2) warns or instructs but only some give right of way. In this case, sign 1 marks that you have priority at the junction, so vehicles from other directions must yield to you. Understanding these signs helps ensure smooth traffic flow and avoid accidents at intersections.
