previous answer wrong . It means you cannot cross the line
Two continuous lines down the middle of the road indicate that you should not pass on that section of road. Most often, this is because visibility is limited on that stretch of highway.
do not cross to change lanes or pass
The yellow solid line in the middle of the road means that you are to stay on your side of the road, no passing!
Possibilities are: Single or Double white line, Single or Double yellow line, Solid white line next to broken white line, Solid yellow line next to broken white line, No line on rural country lane roads.
A center line that is solid yellow signifies a no passing zone for the lane the line is on. A double yellow line means no passing for either lane. A broken yellow line means you can pass another vehicle.
Lane markings on roads are very important; they let the driver know the rules of the road. Solid centerlines usually yellow or white indicate the driver should not cross the line and stick to their side of the road to prevent accidents.
A two lane roadway usually has a yellow dotted line down the center separating traffic lanes. When the line changes to a solid line, it means "No Passing". If the solid line is to the right of center then that lane has a "No Passing" restriction. When there is a double yellow line, there is "No Passing" in either direction.
The road edge on the right side is marked by a _________ line.
Yellow lines of all types indicate the leftmost edge of where you can drive in a certain direction. A double solid yellow line may not be crossed except when making a left-hand turn to either leave or join the road divided by said line. A single yellow line on a two-lane, two-way road serves the same purpose. Some jurisdictions use yellow lines on one-way roadways or divided highways to indicate the left edge of the roadway.

Double solid white lines are there so drivers on each lane do not cross the white lines. There are roads where 1 side will have a solid white line and the other is dashed, again that means the side with the solid white line can not overtake where as the other side can.
On a road, a solid line divides lanes of traffic which are going in opposite directions. A line composed of dashes divides lanes of traffic going in the same direction.
