Wrong way on a bike lane? Is it OK to ride the opposite way on a designated bike lane? I'm in Louisville, Kentucky, USA. The reason I ask is because most of the lanes near me are only on one side of the road. The picture below is an example of the type of lane.



The law where I live allows me to ride on the road, bike lane or not.

Is it better to ride the opposite way or ride on the roadway as you would if there wasn't a bike lane?

Edit: I added a different picture that better represents the bike lane. It is actually a two way street with one bike lane in one direction.
In general, if a bike path (lane) is on a road, follow the direction of traffic on that road. If there isn't a bike path on the other side, then bike carefully in the road if permitted, or find a different route. 

If a bike path is separated from the road and there aren't directional signs, stay to the appropriate side of the bike path depending on where in the world you are (right for most of the world, left for fans of the queen typically). If there are bike paths on both sides of a road, use the direction of the closest bit of road. 

Do not go the opposite direction of what is marked!

(*) In the original post, there was an arrow indicating what direction traffic on the bike path was to go; in this case, it should be obvious -- follow the marked direction.
