What do yellow lines on the road signify?

Yellow lines on the road are used to indicate the separation of traffic traveling in opposite directions. This means that if you see a solid yellow line, it signifies that passing is not allowed, while a broken yellow line typically indicates that passing is permitted when safe. The presence of yellow lines helps regulate traffic flow and enhances safety by clearly marking lanes that are meant for vehicles coming from opposite directions.

Understanding this concept is crucial for safe driving, as recognizing road markings, including yellow lines, helps drivers navigate the roadway correctly and adhere to traffic regulations. Other options incorporate meanings associated with different types of lines or signs instead. For example, white lines generally signify lanes for traffic traveling in the same direction, while parking restrictions are typically communicated through signs rather than road markings. Thus, recognizing the specific meanings of yellow lines reinforces safe driving practices and contributes to overall road safety.
