What is indicated by yellow lines on the road?

Yellow lines on the road are used to separate lanes of traffic moving in opposite directions. This means that when you see yellow lines, you should be aware that vehicles traveling in the opposite direction are coming toward you. In most cases, a solid yellow line indicates that passing is not allowed, while a dashed yellow line permits passing when it is safe to do so. Understanding this road marking is essential for maintaining safety and ensuring that drivers follow the correct traffic regulations. The other options do not accurately represent the role of yellow lines; for instance, they do not signify traffic moving in one direction or pedestrian crossings, nor do they indicate no parking areas, both of which typically use different line colors or styles.
