One correspondent observed that "It seems that drivers in BC generally have a big problem when it comes to merging. In this case let's say from two lanes to one. In the normal course of events merging shouldn't be any hassle at all - take turns, one from the left then one from the right - it all moves along nicely, and has a minimal effect on holding up traffic. Not in BC! Here it appears to be everyone for him / herself."
In a perfect world the reader would never have raised this issue. We would all be courteous to each other and take turns when we were presented with a situation where merging was required. All would proceed happily and no one would have to spend more time than the other waiting their turn.
The merging traffic sign warns motorists on a main roadway that they may encounter vehicles entering the lane ahead.
