Rear Road Captain Duties:

The Rear Road Captain serves as the eyes of the Ride Leader.

He watches the formation, and informs the Ride Leader of any potential problems within the group.

He watches other vehicles, and informs the Ride Leader (and anyone else with radios) of hazardous conditions approaching from the rear, such as vehicles trying to cut into the formation and trucks passing with potentially dangerous wind blasts.

He will watch for merging lanes, and will move into a merging lane (or stay in a merging lane just vacated by the group) in order to "close the door" on other vehicles that may otherwise find themselves trying to merge into the formation.

The Rear Road Captain changes lanes BEFORE the formation, to secure the lane so the formation can move into it safely.
