What Is The Difference Between Added Lane Sign and Merge Sign?

Added Lane Sign and Merge Sign: What is the difference?

Both signs indicate that there is a point where traffic on another road will come together with traffic on the mainstream. And these two signs look a little bit like each other with a straight arrow pointing at the front and another arrow leaning towards it. But there is one important difference.

The added lane sign means that a new lane will be added to the mainstream road and drivers can continue driving on this lane. Entering traffic does not need to merge at this point.

The emerge sign means that two separate roadways will come together and become one lane. Drivers should prepare to merge into the mainstream traffic.
