We have found fewer people get lost out of the group
if both the leader and last car (the shepherd) know
and coordinate together to keep everyone together.
A CB radio can be very useful on drives with many cars.
If you do need the group to stop and have no radio, let
the other drivers know by either holding up a fist
top is down or flashing your lights. If that hasn't gotten
the lead car's attention when you are at
the place to stop,
turn your turn signal on for some distance before and go ahead
and turn in. Someone should see you and the group will stop.
If you notice a car signaling to make a stop, pass on the
the lead car.
If you do get lost from the group and have no radio to
contact the others, return to the last place you were
with them or if you know where they are going, go on ahead.
Drive in the position you are comfortable for everyone's
peace of mind: Faster drivers near the front; those
going slower, toward the rear.
Allow the leader to see the last car after a turn or traffic
light so he/she is sure everyone is together. The
last car need to drive close to the centerline, all others
drive close to the shoulder line.
"Drop crumbs" so those behind know where to turn
- If the group has made a turn and the car behind you
not see you and the others turning, wait for them to see you
make the turn.
"Caterpillar" to pull into traffic together -
The last car pulls out to hold the place in traffic and the
rest of the group pulls out together. It is also helpful for
the last cars to hold a place for the others to get over to
another lane on the freeway or on other multi-lane streets.
If you decide to leave the group, indicate to someone you
are leaving by a wave or tell someone at a stop,
so the others
will not wonder if you are lost.
