Yellow lines painted in the center of a road indicate that traffic on that road is two-way, that is, on that stay the cars drive in both directions of direction, each direction on one side of the lines. You may have noticed that sometimes these lines are broken and sometimes the lines are solid, and sometimes the road has a broken line next to a solid line. What does this mean? Well, when the road has two broken lines it means that cars on both sides can move to the opposite lane. If both lines are solid, it is forbidden for any car to pass to the opposite lane.
If the road has a solid line and a broken line, it is only allowed to pass to the next lane, the car on the side of the broken line, the car on the side of the solid line cannot pass.
