What do yellow lines indicate about passing other vehicles?

Yellow lines on the road serve as critical markers for drivers regarding the rules of passing vehicles. Specifically, when a yellow line is present, it indicates that the road is a two-way street, and the color yellow typically signifies caution regarding passing. A solid yellow line means that passing is prohibited for vehicles traveling in either direction. Therefore, when you encounter yellow lines, the safest and most correct interpretation is that it is not permissible to pass another vehicle.

While options might mention encouragement or allowance of passing, understanding the role of yellow lines primarily focuses on the prohibition when they are solid, emphasizing the necessity of adhering to road safety standards and rules. This is particularly important for preventing accidents, as passing inappropriately can lead to dangerous situations for all road users. Hence, recognizing that yellow lines indicate the need for caution and often signify that passing should not occur is key to safe driving practices.
