What is the etiquette for passing a funeral procession?
The etiquette is not to cut through, which is why off duty officers do escort for processions beyond a certain length to stop traffic at intersections. When it comes to the freeway, however, the procession needs to go freeway speed and you can cut the line to enter and exit. There is no law about it; just etiquette. But there are always some exceptions and that’s one of them.
