增加车道标志
MUTCD W4-3
前方增加一条车道,无需合并。
标志外观
A yellow diamond warning sign with a black symbol showing an extra lane joining your roadway to indicate an added lane ahead.
什么时候会见到
It appears where a new lane begins alongside yours, often at freeway entrances, so entering traffic has its own lane.
该怎么做
Continue in your lane; you do not need to merge, but stay aware of vehicles entering in the added lane.
