What types of markings might be painted on roadway surfaces?

The correct answer is focused on the variety of markings that can be painted on roadway surfaces to enhance safety and guide drivers. Markings may include words or symbols that serve to provide essential information for navigation, communicate warnings, or establish rules for traffic regulation. For example, stop signs and yield markings are crucial for indicating actions that drivers must take, while symbols may denote things like bike lanes or pedestrian crossings. This multifaceted approach to roadway markings is designed to reduce confusion and improve overall traffic flow, thus contributing to safer driving conditions.

The other options suggest a more limited scope of what road markings can depict. Lane demarcations, directional arrows, and speed limit indicators are important, but they represent only specific categories of the broader range of markings that are necessary for comprehensive traffic control and safety.
