The yellow signs always show times when it is not permitted to park on single yellow lines in the area where they operates and they are valid only on the side of the road where thehave been installed. In this case, parking is allowed on the single yellow line everyday between 18:30 and 08:30 and all day Sunday. If the yellow sign is only present on one side of the road, that means that the other side (where no such sign exists) does not allow parking at any time. In this case, both sides have yellow signs with the same hours posted which means parking is permitted on both sides of the road but only outside the posted hours.
