Answer: D — Orange and white

The standard colors for barricades, specifically in the context of temporary traffic control, are typically orange and white. Orange is used predominantly for construction and maintenance activities on roadways, signaling caution to drivers and pedestrians. The white stripes are often used in conjunction with orange to enhance visibility and indicate the presence of a temporary work zone. Using these colors helps ensure that barricades are easily recognizable, allowing for quick identification of areas that require caution. This recognition is crucial for maintaining safety for both workers and road users during construction efforts. Overall, the use of orange and white for barricades is a well-established practice in traffic control, aligning with safety standards to promote awareness and prevent accidents in work zones.
