If you mean a diamond on the lane, that means that that lane is for BICYCLISTS ONLY, if you mean as a shape of a sign such as a "slippery when wet" sign, that usually tells you important things. I looked it up in my "Virginia Driver's Manual" and it says a diamond shaped sign is a warning sign.
If the left lane is ending, and merging into the right lane, then the car already in the right lane has right of way.
It will most likely mean merge into the left hand lane.
lane ends ahead Emergency vehicles only
It is found in VERY few areas and it means a change in the road from a 4 lane to a 2 lane road.
It means bike path/bike lane.
Keep right of where the sign is placed. A sign telling you to get to the far right lane would be telling you to merge right, and would be used either in conjunction with signs indicating the left lane(s) end(s), painted lines which deviate towards the right lane, and barrels and delineators (in instances of a work zone in which lanes are closed off).
If you intend to turn right, move into the lane marked by the sign. If you do not, leave that lane.
