A raised pavement marker is a safety device used on roads. These devices are usually made with plastic, ceramic, or occasionally metal, and come in a variety of shapes and colors. Raised reflective markers include a lens or sheeting that enhances their visibility by reflecting automotive headlights. Some other names for specific types of raised pavement markers include Botts' dots, delineators, cat's eyes, road studs, or road turtles. Sometimes they are simply referred to as reflectors.

Famous quotes containing the words raised, pavement and/or marker:
“It is worth the expense of youthful days and costly hours, if you learn only some words of an ancient language, which are raised out of the trivialness of the street, to be perpetual suggestions and provocations. It is not in vain that the farmer remembers and repeats the few Latin words which he has heard.”
—Henry David Thoreau (1817–1862)
“Down in the street there are ice-cream parlors to go to
And the pavement is a nice, bluish slate-gray. People laugh a lot.”
—John Ashbery (b. 1927)
“Personal change, growth, development, identity formation—these tasks that once were thought to belong to childhood and adolescence alone now are recognized as part of adult life as well. Gone is the belief that adulthood is, or ought to be, a time of internal peace and comfort, that growing pains belong only to the young; gone the belief that these are marker events—a job, a mate, a child—through which we will pass into a life of relative ease.”
—Lillian Breslow Rubin (20th century)
