Final answer:
The sign with an arrow coming off another arrow means 'Lane ends, merge right.' This sign instructs drivers that their current lane will soon end and they should prepare to merge safely into the right lane.
Step-by-step explanation:
The sign with the arrow coming off the other arrow typically means lane ends, merge right. This is a common road sign indicating that the lane you are currently in will end soon and you need to safely merge into the lane on your right. Drivers are expected to use the merging sign as a warning to prepare for the lane reduction and change lanes smoothly without causing disruptions in traffic flow.
The description in the question suggests a sign that represents the merging of traffic from one lane to another, specifically instructing drivers to change lanes or merge into the flow of traffic on the right. It does not indicate an exit to the right, a requirement to simply keep right, or a merge to the left, but rather informs drivers that the lane they are in is coming to an end and they should prepare to merge to the right.
