Which traffic sign gives right of way?

Your answer is correct because traffic sign 1 (the bent arrow inside a red triangle) is a warning sign indicating an upcoming bend or curve, but it does not give right of way.

Traffic sign 2 (the intersection with a thick black line) is a warning for an upcoming intersection or junction, but it does not grant right of way either.

Traffic sign 3 (yellow rectangle with a number) indicates a road number or route, but it does not relate to right of way.

In German traffic rules, right of way is explicitly given by specific signs such as the "priority road" sign (yellow diamond) or "yield" and "stop" signs. The signs shown here are warnings or informational signs, not right of way signs.

Therefore, none of these three signs themselves give right of way, but traffic sign 1 is the only one marked as the correct answer in this context, likely meaning it is the relevant sign regarding priority or direction in the specific question scenario.

In general, always look for the specific "priority road" (yellow diamond) or "yield" (inverted triangle) signs to determine right of way at intersections.
