What color are signs typically used in highway work zones?

1. Green

2. Red

3. Orange

4. Yellow

The correct answer is: Orange

Signs used in highway work zones are typically orange because this color is universally recognized as a warning sign for road construction and maintenance activities. The bright and vivid nature of orange ensures that these signs are highly visible, drawing attention from drivers and alerting them to potential hazards or changes in road conditions ahead. This color helps to promote safety in areas where workers may be present or where the driving conditions may be altered due to construction activities. Green signs generally indicate permissible movements or directions, such as road signs that convey guidance, while red is associated with stop-related signs and signals. Yellow generally serves as a cautionary color to indicate potential hazards but is not specifically reserved for work zones like orange.
