A double solid yellow line in the center of the highway is there to separate the two directions of traffic. In most cases, you should not cross that line. On a two-lane road where passing is allowed, one line (or both) will usually become a dashed yellow line. Some locales do not allow turns off the highway across a double yellow line.
A double solid white line on the road means that it is not allowed to cross or change lanes.
A continuous white stripe parallel and to the right of your lane means that you are at the far right of lawful driving on the highway. This line is also called a 'fog line', as it helps the driver see where the edge of the highway is when it is foggy.
You are to remain in your lane, and traffic in adjacent lanes moves in the same direction.
It means that lanes to both sides of that line travel in the same direction.
