Commonly known as truncated dome mats, these detectable warning surfaces feature raised, slip-resistant domes arranged in a distinct grid pattern. Usually molded in bright red or yellow polyurethane or cast iron, they must contrast visually with the surrounding concrete sidewalk. In NYC, the DOT mandates these tiles at the transition boundary of every curb ramp and public pedestrian crosswalk, helping visually impaired individuals identify the physical edge of the street safely.
