What does a "lane ends" sign indicate?

A "lane ends" sign signals to drivers that a particular lane will soon come to an end, and they need to prepare to merge into the adjacent lane. This warning is crucial for maintaining traffic flow and ensuring safety, as it alerts drivers to check their surroundings for other vehicles and adjust their position accordingly. Recognizing this sign allows drivers to make the necessary lane changes in an orderly and safe manner, avoiding sudden movements that could lead to accidents. Options indicating lane closures for repairs, increased traffic, or mandatory turns do not accurately describe the function of a "lane ends" sign, which specifically pertains to the termination of a lane and the need for merging.
