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

To indicate that it is the left side of the road. If you see a yellow line on your right you are driving in the oncoming traffic lane. When the yellow line is on the edge of the road you are on a divided roadway and the median is to the left of the yellow line. You will find a white line on the right side of the road. When the yellow line is in the center of the road you are driving on a two-way undivided roadway. Again, if the yellow line is on your right you are in the oncoming traffic lane.

It means it is a passing zone if just the line is broken. If the road is also indented, it is just a warning for when you drive over it, it will make a thudding noise to alert you.
