Which road sign forbids you from entering the signposted area?

You chose both traffic sign 1 and traffic sign 2, which is correct. The first sign marks a pedestrian zone, where entry is forbidden for vehicles unless an exception applies. The second sign is the classic "no entry" sign, meaning all traffic is prohibited from entering from that direction. The third sign does not mean entry is forbidden; instead, it regulates priority at narrow sections where vehicles from the opposite direction must yield. In summary, for questions about forbidden entry, always look for the pedestrian zone and no entry signs.
