The procession to the funeral site could be led by Law Enforcement. If there is no Law Enforcement, the Ride Captain will designate the lead escort motorcycle and most likely the order of the riders to follow.
The Patriot Guard Road Guards will follow them, and lead the Patriot Guard flag honor guard. It is their job to read the traffic and help the LEO keep us safe.
Motorcycle processions travel in columns of two, staggered.
Automobiles are single-file.
Road Guards will have their flashers on.
All others will have their headlights on.
Automobiles will have lights on, and the last vehicle will also have flashers on.
This alerts the LEO and Road Guards that the last vehicle is the end of the procession.
