Which type of lane markings separate lanes going in the same direction?

White lane markings are used to separate lanes of traffic that are moving in the same direction. This is a standard convention in road marking to help guide drivers and maintain orderly traffic flow. White lines indicate that vehicle lanes are for the same direction of travel, whether in a single lane road or in multi-lane configurations.

In contrast, yellow lane markings are used primarily to separate traffic moving in opposite directions, indicating areas where passing is allowed or prohibited. Red and blue markings are not commonly used for lane separation; red is sometimes used for stop lines or no parking zones, while blue can indicate specific vehicle access areas, such as for disabled drivers. Understanding the purpose of lane markings is crucial for safe driving and navigating roads effectively.
