Which of the following is NOT a typical traffic control device?

• A. Traffic cones
• B. Portable traffic signals
• C. Decorative road art
• D. Flashing warning lights

Answer: (C)

Decorative road art is not considered a typical traffic control device because its primary purpose is aesthetic rather than functional. Traffic control devices are specifically designed to manage the flow of vehicles and pedestrians, communicate important information, and enhance safety on the road. Traffic cones, portable traffic signals, and flashing warning lights all serve practical purposes in traffic management. Cones are commonly used to delineate work zones, portable traffic signals help regulate traffic flow in temporary settings, and flashing warning lights typically alert drivers to potential hazards or changes in traffic conditions. None of these devices are primarily ornamental, illustrating the distinction between effective traffic control measures and purely decorative elements on the roadway.
