Louisiana Driver's Guide Class E Practice Exam

The color associated with construction or detour warnings on signs is orange. This color is specifically used to alert drivers to changes in or around work zones where construction is taking place. Orange conveys a sense of caution and is highly visible, making it effective in alerting drivers to potential hazards and the need to slow down or change lanes. Yellow, while it represents general caution in driving situations, is not specific to construction areas. Red indicates stop or prohibitive actions, often used for stop signs or signals. Green typically signifies a go or a safe condition, such as indicating direction or information pertaining to routes. Thus, orange is the definitive color used to signal that drivers should be attentive due to construction or detours ahead.
