What is the purpose of a Shadow Vehicle?

• A. To monitor traffic conditions
• B. To provide lighting
• C. To transport equipment
• D. Prevent vehicles from entering the work zone

Answer: (D)

A Shadow Vehicle is used as a visible protective buffer in work zones to deter drivers from entering the area where workers and equipment are. It travels with the flow of traffic and uses flashing lights and signals to clearly indicate the boundary of the work zone, helping to prevent intrusions before they happen. While it may contribute to visibility, its main purpose is to keep vehicles out of the work area, not to monitor traffic conditions, provide lighting, or transport equipment. Therefore, the best answer emphasizes preventing access to the work zone.
