When did Russia start to drive on the right, and why?

Since it is advantageous for a right handed person to ride his horse on the left hand side of the highway, the left hand rule of the road was almost universal until the Jacobins in France in the 1790s decided to impose the maritime rule of passing port to port on land transport for the mere sake of uniformity. Bonaparte, Hitler, Mussolini and Chang Kai Check imposed the French rule on the places they ruled or conquered. But why ever should czarist Russia have adopted a French idea?
