"they usally show you where you are on the road so you can tell your not off of it im just throwing out a guess! LOLZ!!! "
It actually means that you are in a no-passing area. You may only pass the car in front of you if the lines are dashes, not solid.
This typically happens on a two-lane road: one lane going in each direction. The dashed line tells you that you may pass if it is safe to do so. A solid line tells you that you cannot pass here....and in fact, would be issued a ticket if you try!
The traffic coming the other way may have a dashed line...and yours may be solid. This tends to happen as you are approaching a curve in the road that the opposing traffic has just driven through. They are now free to pass each other, but you are not.

Double solid yellow is between two lanes of traffic with oppsing directions. This indicates no passing a vehicle that is traveling the same direction by moving to the oposing lane momentarily. You have to stay in your lane. Solid white is a line between two lanes going the same direction, but indicates changing lanes is not admissable unless safety concerns exist. Again, you have to stay in your lane.
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.
In the USA it is generally illegal to pass anyone on the right.
