This sign indicates that two lanes of traffic are about to come together and drivers in both lanes should prepare to adjust speed and position to allow for a smooth integration of traffic.
These signs are critical for maintaining safe traffic flow on roadways where lanes reduce in number or where roadways combine.A sign that directs the driver to change speed and vehicle position to merge into the lane safely is the merge sign.
The merge sign typically consists of two arrows merging into one, indicating that the driver should adjust their speed and position to merge with the traffic in the indicated lane. This sign is commonly seen on highways or freeways where lanes merge together.
