Which vehicle in a funeral procession must follow stop signs and traffic control signals?

The lead vehicle in a funeral procession must follow stop signs and traffic control signals because it is often responsible for indicating the actions of the other vehicles in the line. While funeral processions may generally have the right of way and are allowed to proceed through intersections without stopping, the lead vehicle is critical in ensuring safety and compliance with traffic laws as it navigates through various traffic scenarios.

Following stop signs and signals by the lead vehicle helps to maintain awareness of other traffic and ensures that the procession can safely proceed. The last vehicle and all vehicles typically follow the lead vehicle's example, but explicitly, the lead vehicle must adhere to these traffic rules to set the right precedent and ensure the safety of both the procession participants and other road users.

This adherence prevents potential conflicts at intersections and upholds public safety, even though the procession may generally receive leniency concerning stop signs and signals.
