What do yellow lane lines indicate?

Yellow lane lines are used to separate lanes of traffic moving in opposite directions. This visual cue is critical for ensuring that drivers stay in their respective lanes and navigate safely through areas where traffic flows toward each other. The distinct color of yellow is used for this purpose to draw attention and convey the need for caution.

In situations where yellow lines are present, it is vital for drivers to be aware of oncoming vehicles and the potential for head-on collisions if they drift into the opposite lane. Following these markings helps maintain an organized flow of traffic and reduces the risk of accidents.

The other choices pertain to different lane marking colors or functionalities. For instance, separate lanes of traffic moving in the same direction typically use white lines, while no parking areas are usually marked with signs or other indications rather than specific lane lines. Similarly, edges of streets are generally outlined with solid white lines rather than yellow ones. Understanding these distinctions is essential for driving safely and responsibly.
