The traffic sign "Direction indication by arrows" (1000-21) consists of arrows that indicate the direction in which vehicles must go. These arrows may point straight ahead, to the left, or to the right.

This sign is typically used to guide drivers at intersections or locations where multiple routes are available. It ensures that drivers understand the correct path to follow, helping to prevent confusion and maintain smooth traffic flow.

When you see this sign, you must follow the direction indicated by the arrows. If the arrow points straight, you are allowed to go straight ahead. If it points left or right, you are required to turn in that direction. Always be cautious of other road users when following these indications.
