A solid yellow line next to a broken yellow line means that vehicles next to the broken line may pass. The yellow lines define the road as two way, traffic opposing each other. The side of the road with the solid yellow line facing it is a no-passing zone, while the opposite side of the road, with the intermittent line facing it, passing is permitted.

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.

The yellow is a stark contrast to the black/grey especially at night or poor driving conditions i.e. fog and snow - In some countries they use white which can "disappear" in poor condition yet use the yellow to mark restricted stopping and parking
a blur? no if you are in a passing lane the line to the right will be a white line that has skips, and the line to your left will be a solid yellow or double yellow
