Which vehicles must follow the direction of a traffic officer in a funeral procession?

All vehicles in a funeral procession are required to follow the direction of a traffic officer. This requirement helps ensure the safety and order of the procession, allowing it to proceed smoothly through intersections and busy roadways. Traffic officers are specifically positioned to manage and direct traffic in such sensitive situations, recognizing the need for respect and consideration for the grieving families and their guests. By coordinating the movement of all vehicles in the procession, they help prevent accidents and disruptions that could arise when vehicles are left to navigate independently, especially in the context of a funeral where emotions are heightened. Thus, it's imperative that every vehicle in the procession adheres to the directions given by the traffic officer to maintain safety and dignity during the event.
