What do yellow center lines indicate on the road?

Yellow center lines on the road indicate that there is two-way traffic flowing in opposite directions. This marking is critical for ensuring safe driving practices, as it helps guide drivers in understanding the flow of traffic and the need to stay on their side of the road. When drivers see yellow lines, they should be cautious and attentive to vehicles coming from the opposite direction, particularly when considering passing maneuvers. The presence of yellow lines serves as a visual cue for drivers to be aware of oncoming traffic, thus contributing to road safety. Other options, such as indicating one-way traffic or construction zones, do not apply, as those situations typically use different colors or types of road markings. Pedestrian crossings are usually designated with specific symbols or signs rather than with center line colors. Understanding these markings is essential for all drivers to navigate roads safely and effectively.
