Where I come from, with the exception of huge funerals (e.g., for cops or firefighters killed in the line of duty) funeral processions are routinely done without any police or private escort.
Everybody just puts on their lights (or in some cases their hazard lights), the hearse leads the way and every driver follows the car in front of him, and traffic laws are obeyed. It doesn’t seem all that complicated.
(e.g., for cops or firefighters killed in the line of duty)
I would make an exception for these cases. This is a PUBLIC display of sorrow and respect, not personal.
