Construction Ahead Warning Sign - Road Safety Symbol #1477256 (License: Personal Use)

The image displays a standard MUTCD (Manual on Uniform Traffic Control Devices) W21-1 “Road Work” warning sign: a bright yellow diamond with a bold black border and a stylized silhouette of a person using a shovel on a mound of earth. Its high-contrast design ensures visibility in daylight and under headlights, communicating imminent construction activity to drivers well in advance. This sign is typically placed at the beginning of work zones to prompt safe speed reduction and increased attention.

Used on highways, urban streets, and rural roads to mark the start of temporary construction zones; matches user intent for understanding traffic signage, driver education, or municipal safety resources.
