What is the purpose of white lettering and symbols painted on the roadway?

White lettering and symbols painted on the roadway serve as an important supplement to traffic signs. They provide clear and immediate instructions or information to drivers, helping them navigate the road safely and efficiently. For instance, lane markings can indicate where to stop, where to turn, or guide drivers on how to safely merge into different lanes.

This roadway marking system ensures that drivers can receive essential information even when they are not close to a sign, and it often conveys messages that are time-sensitive or location-specific, such as "Yield," "Stop," or symbols for specific lane usages, like HOV or bike lanes. The combination of signs and pavement markings enhances overall road safety by improving communication with drivers.

Other options, such as enhancing visibility, directing traffic, or causing confusion, do not accurately capture the role of these markings, as they primarily function to provide supplementary visual cues rather than to serve as standalone navigational guidance. Their design aims to improve clarity and understanding for drivers on the roadway, thereby promoting safer driving practices.
