By the way, woe to the non-funeral motorist in another, parallel lane, who doesn't stop at a red light or Stop sign, before proceeding through it at the same time as the procession! If your vehicle isn't displaying that company's funeral sticker, it might be a good idea to just pull over and park where it's allowed, until the funeral procession has passed on by. But watch your rear and side view mirrors for relays of speeding motorcycle escorts coming up behind you, before you make a move. Then, change lanes or turn safely into a side street away from the procession itself.
