Road markings are painted or applied lines, symbols, and words on pavement that guide drivers and enhance safety. Common markings include centre lines (separating opposing traffic), lane lines, edge lines, crosswalks, turn arrows, stop bars, and various symbols indicating hazards or regulations. Markings use standardized colours: white separates traffic moving the same direction, yellow separates opposing directions. Durable paint, thermoplastic, or tape materials withstand traffic and weather. Municipal public works crews maintain markings on local roads, repainting as lines fade. Marking designs follow provincial traffic manual standards. Reflective materials improve nighttime visibility. Quality markings are essential for road safety.
