What is the purpose of road markings?

The purpose of road markings is to indicate lanes, directions, and rules for driving. These markings play a crucial role in traffic management and safety by providing clear visual cues to drivers about how to navigate roadways effectively. They help maintain order on the roads by delineating lane boundaries, guiding vehicles in their intended directions, and indicating regulations such as speed limits and no-passing zones. By following these markings, drivers can make informed decisions, which significantly contributes to reducing accidents and promoting smooth traffic flow.

The other options do not accurately reflect the primary function of road markings. For instance, encouraging racing behavior or confusing drivers is counterproductive to road safety and traffic regulation, while decorating the roadway implies a purpose that is aesthetic rather than functional.
