What is the purpose of delineators on the roadway?

Delineators serve the essential function of marking the alignment of the roadway. They are often used to enhance visibility, particularly in areas where the road curves or where two lanes separate, thereby helping drivers understand the path of the road ahead. These devices are typically reflective and positioned at intervals along the edges or centerline of the road to clearly delineate the travel lanes, especially under low-visibility conditions such as at night or during inclement weather.

By defining the roadway's shape and layout, delineators contribute significantly to road safety, guiding drivers and ensuring they remain within the designated travel paths. They help in preventing accidents that may arise from drivers straying from their intended course.
