Which of the following is NOT a type of pavement marking?

Reflective glass beads are used in conjunction with pavement markings to enhance visibility but do not serve as a type of pavement marking themselves. They are typically embedded in the paint or used as part of the thermoplastic materials applied to the road surface to increase reflectivity and improve safety during nighttime or adverse weather conditions. Therefore, while they are an essential component of traffic control measures, they are not classified as a type of marking. In contrast, paint, pressure-sensitive tape, and raised pavement markers are all recognized methods of marking the pavement directly, guiding drivers and delineating lanes and other important traffic information accurately on the roadway.
