Is the shadow vehicle part of the flagging operation?

The shadow vehicle is indeed considered an integral part of the flagging operation. Its primary role is to enhance safety by creating a buffer between traffic and the workers in the work zone. A shadow vehicle is typically equipped with warning lights and other safety features, allowing it to absorb potential impacts from errant vehicles, thereby protecting flaggers and other personnel.

Implementing a shadow vehicle is especially important in scenarios where traffic volumes are high or where drivers may not be fully attentive, as it helps to provide an additional layer of protection. This aligns with best practices in maintenance of traffic (MOT) for minimizing risks to both workers and drivers in work zones. Therefore, it's essential to include the shadow vehicle as part of a well-planned flagging operation to ensure optimal safety for all involved.
