The traffic sign "Direction indication by arrows" (1000-13) is designed to guide drivers on the path they should take. This sign typically consists of multiple arrows pointing in various directions (e.g., straight ahead, left, right). Each arrow indicates the permissible routes for vehicles, helping to facilitate smooth traffic flow and ensure that drivers are aware of their options at an intersection or junction.

In practical terms, if you see this sign, pay attention to the arrows which signify the directions you can legally travel. Follow the signs closely to adhere to the designated paths, as this is crucial for maintaining traffic order and safety. If you have any further questions about traffic rules or need more clarification, feel free to ask!
