Information signs

An information sign is a traffic sign that provides useful guidance or clarification to road users without imposing rules or warnings. These signs inform drivers about things like parking zones, directions, facilities, road layouts, or the start and end of built-up areas. Their purpose is to help drivers navigate confidently by giving clear, practical information that improves orientation, comfort, and overall traffic flow.
