What does a "merge" sign instruct drivers to do?

The "merge" sign is specifically designed to instruct drivers that they need to converge into one lane due to the road configuration ahead. This often occurs when one lane is ending or when multiple lanes are coming together. The intent of the sign is to facilitate a safe and orderly transition for vehicles, ensuring that drivers are aware of the change in lane structure and can adjust their positioning accordingly.

Drivers who see a "merge" sign should be prepared to change lanes safely, while also being aware of other vehicles in the vicinity that may also be adjusting their position. This encourages smoother traffic flow and reduces the likelihood of accidents that can occur due to sudden lane changes or improper merging. Understanding this clear signal is crucial for maintaining safety in work zones or areas where traffic conditions are altered.
