Solid yellow line

If it is painted next to the center line on your side of the road, you must never cross a solid yellow line unless if you are directed by a traffic enforcer to do so, or if you are turning into a driveway. If the yellow line is on the other side of the center line and the dashed white line is on your side, then you can cross to the other side of the road if it’s safe to do so.

The yellow line is also known as the no-passing line. It is painted on roads where it is usually hazardous to cross the center line because there might be sharp bends or corners that restrict your view of approaching vehicles, dips in the road that could be hiding cars, close to a busy intersection, or it might be a hot spot of accidents so it’s unsafe to overtake by passing through the yellow line.

The only time you could overtake with the presence of a yellow no-passing line is when the lane is wide enough for two vehicles, you could see 100 meters of clear road ahead of you while you overtake, and you stay on your side of the yellow line. If not, you’ll have to wait until the yellow line ends to be able to overtake.

In the picture above, car B is allowed to overtake by moving into the other lane, while car A must not go over the yellow line to overtake.
