Final answer:
The sign that indicates that the road narrows and the right lane ends is the merge sign.
Step-by-step explanation:
The sign that indicates that the road narrows and the right lane ends is the merge sign.
This sign is usually a yellow diamond-shaped sign with two curved arrows merging together in the center, indicating that the two lanes will merge into one.
The sign may also have additional arrows to indicate the direction of the merge.
When you see this sign, it means that you should start merging into the left lane if you are in the right lane. Be sure to check your blind spots and use your turn signal to indicate your intention to merge.
