Please do not use the words "left" and "right", because they are meaningless by themselves, as long as the reader does not know whether you mean left-hand traffic or right-hand traffic. Sure, if I analyze the text long enough, I can probably find out, but you and everybody else can make this easier by referring to the edge of the road, the centerline, the passing lane, the shoulder, the driver side, etc.
If I was posting on an international area of the forum I would indeed describe things differently. This is the UK and Ireland section and we all drive on the same side of the road ... so, no confusion!
