The blue vertical sign with the symbol of a motorway and a bridge (sign H1a) indicates entry onto a motorway. This indication sign must be placed precisely in the locations where drivers begin driving on this road, marking the point from which the special traffic rules applicable to motorways come into effect. The other options are incorrect because the road reserved for cars and motorcycles is identified by a different sign (sign H2, which shows the symbol of a car from the front on a blue background). Therefore, the sign in the image does not apply to reserved roads or to both simultaneously.
