What do these traffic signs allow?

This sign indicates a parking area reserved for residents, but only those who have a valid parking permit with the corresponding number displayed on the sign may park here. It means parking is restricted and not open to everyone or even all residents in general. This system aims to ensure that only authorized residents who have been issued specific permits can use these spaces, typically to reduce parking issues in residential areas. So, if you do not have the specific permit number shown, you are not allowed to park here.
