A little more info on funeral processions

The law is pretty uniform across the vast majority of states. Funerals can proceed through red lights and stop signs as long as the lead vehicle went through legally , first. All states that do have laws, require all vehicles in the procession to have headlights on and emergency flashers on. There are a few states that require flags on vehicles in the procession. Here is a link to where I found this info.
