What should drivers be doing when they see a sign indicating merging traffic ahead?

When drivers see a sign indicating merging traffic ahead, it is crucial for them to scan to the right for merging vehicles. This practice allows drivers to be aware of any vehicles that may be entering their lane from a merging lane. By actively scanning the area, a driver can assess the speed and position of approaching vehicles and adjust their driving accordingly—whether that means changing lanes, slowing down, or maintaining speed.

This awareness not only helps in avoiding potential collisions but also promotes smoother traffic flow by giving drivers the opportunity to yield to merging traffic when necessary. Awareness of merging vehicles is an important aspect of defensive driving and enhances overall road safety.
