In the USA, it means no passing.
no passing
two different lanes
A double solid white line separates two lanes of traffic going in the same direction. Crossing a double solid line is prohibited.
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.
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.
Depending on which country you are in. Generally it means 'Do not cross', keep to your your lane, no passing.
