What is allowed at this traffic sign?

You are correct in choosing options 1 and 2. This traffic sign indicates "No Parking," but stopping briefly is allowed under certain conditions. Specifically, you may stop to load or unload goods, or for passengers to get in or out (option 1). Additionally, you may wait for a short time, typically up to 3 minutes, without parking (option 2). However, actual parking, even with a parking disc, is not allowed at this sign (option 3 is incorrect). Understanding this helps prevent improper parking and ensures smooth traffic flow.
