What type of marking is a raised pavement marker considered?

A raised pavement marker is considered reflective because it is designed to enhance visibility, especially at night or during low-light conditions. These markers are typically made from materials that can reflect light, allowing them to stand out against the road surface. The primary function of raised pavement markers as reflective devices is to improve safety by assisting in lane delineation and guiding drivers along the roadway.

While raised pavement markers can be installed permanently in many locations, the key characteristic that aligns with the correct answer focuses on their reflective property. This reflective quality allows them to be effective for nighttime visibility, which contributes significantly to roadway safety. Thus, choosing the reflective nature of raised pavement markers encapsulates their intended purpose and functionality effectively.
