roadlines

Roadlines, or road markings, are painted lines and symbols on pavement that regulate, guide, and inform road users. They delineate traffic lanes, mark road edges, indicate turning and stopping points, and designate pedestrian crossings. Properly maintained roadlines contribute to traffic safety, efficiency, and a predictable driving environment.

Types include center lines, edge lines, lane lines, and turning or pedestrian indicators. Center lines may be dashed to permit passing or solid to prohibit it. Edge lines mark the road boundaries. Lane lines define lanes; crosswalks and stop lines regulate pedestrian crossings and vehicle stopping. Color codes vary by country; white is common for lane and edge lines, yellow for opposing traffic in many regions; double solid lines typically prohibit passing.

Materials and maintenance: Roadlines are painted with durable road paints or thermoplastic materials, often with reflective beads for night visibility. Markings wear with traffic and weather and require periodic repainting. In some areas, raised pavement markers supplement painted lines.

Standards and regulatory context: Standards are set by national authorities and international agreements. In the United States, the Manual on Uniform Traffic Control Devices governs road markings; in Europe, national rules align with harmonized standards. Enforcement rests on local traffic laws, while best practice emphasizes visibility, durability, and consistency.
