What should the first and last vehicles in a funeral procession display?

In a funeral procession, it is crucial for the first and last vehicles to display both lighted headlights and flashing warning lights for safety and visibility. This practice makes the vehicles easier to see for other motorists, which is especially important as the procession may be traveling through traffic intersections or on busy roads. The lighted headlights enhance the overall visibility of the procession, signaling to other drivers that they should exercise caution. The addition of flashing warning lights alerts surrounding drivers even further to the presence of the procession, helping to keep mourners safe during this sensitive time. Properly marking these vehicles communicates to others on the road that they are part of a coordinated group, thus encouraging vehicles to provide the necessary space and respect for the procession.
