Road Work Ahead Sign - Meaning, Standards & Safety Guidance #2057345 (License: Personal Use)

This triangular warning sign features a bold red border, white background, and a black pictogram of a worker using a shovel-standardized under ISO 7010 (W025) and MUTCD (W20-1). It is used on roads and highways to notify motorists of active construction zones, temporary lane closures, or pedestrian workers ahead, prompting reduced speed and heightened attention. The high-contrast design ensures visibility day and night, especially when retroreflective materials are applied.

This image is typically used on transportation safety websites, driver education resources, municipal public works pages, and traffic engineering guides. It serves users seeking to understand road sign meanings, comply with traffic regulations, or design signage for construction projects.
