Question

1. this sign means:

one-way traffic.
intersection ahead.
merging traffic from the right.
highway curves ahead.

Explanation:

The sign in the image is a warning sign. A one - way traffic sign usually has an arrow but in a different context (e.g., a rectangle with an arrow for one - way road signs in some regions). An intersection ahead sign typically has a more complex symbol like two roads meeting. A highway curves ahead sign has a curved arrow. The sign with an arrow that seems to have a "merge" - like appearance (the arrow has a "tail" on one side) is for merging traffic. In traffic sign language, when there is a symbol indicating that traffic is coming from the side (in this case, the right side as the "tail" is on the right of the main arrow) to merge with the main traffic flow, it means merging traffic from the right.

Answer:

Merging traffic from the right.
