What does a merge sign typically depict?

Answer: A — flailing/fraying arrow pointing up

A merge sign typically depicts a flailing or fraying arrow pointing up, which indicates that two lanes of traffic are coming together into one. This sign is designed to alert drivers that they need to prepare for moving from one lane into another, especially in areas where lanes are ending or merging due to roadway configurations. The flaring shape of the arrow emphasizes the need for caution, as drivers may need to adjust their speed or position to allow for smooth merging with the traffic flow. The other options represent different signals or markers. A single straight arrow usually indicates a clear path ahead without any merging, a solid line typically denotes the boundary between lanes where changing lanes is not permitted, and a broken line represents areas where lane changes can be made. Each of these serves distinct purposes for traffic management and safety, but the flailing arrow specifically conveys the merging action that drivers need to be aware of.
