What do white lane markings indicate?

Answer: B — Lanes of traffic moving in the same direction

White lane markings indicate lanes of traffic moving in the same direction. This is essential for road safety and organization, as it helps to guide drivers in maintaining their respective lanes and avoiding collisions. In contrast, yellow lane markings serve to separate lanes of traffic that are moving in opposite directions. Understanding the significance of these markings is critical for safe driving and adhering to traffic regulations. Moreover, other options such as warnings for upcoming stop signs or areas designated for parking are denoted by different types of signs or markings, further emphasizing the specific purpose of white lane markings.
