Be Predictable - Group riding requires even more attention to
predictability than riding alone. Other riders expect you to ride
straight, at a constant speed, unless you indicate differently.

* Change Positions Correctly - Generally, slow traffic stays
right, so you should try to pass others on their left. Say "on your
left" to warn the cyclist ahead that you are passing. DO NOT PASS ON
THE RIGHT. In many cases a cyclist may not hear or be aware of you
approaching them from behind. An unexpected noise may cause that
cyclist to swerve in your direction when you pass. If approaching a
lone cyclist, the offer of "good morning" or "nice day for a bike
ride" lets the cyclist know your position and intent to pass.
* Watch Out At Intersections - When approaching intersections
requiring vehicles to yield or stop, signal your intention with hand
and verbal signals. Call out "slowing" or "stopping" to alert those
behind to the change in speed. In the event the leading cyclist calls
"CLEAR" remember each cyclist is responsible for verifying that there
is no approaching traffic before entering the intersection.

Communicate with the group - Use hand and verbal signals to
communicate with members of the group and with other traffic.

* Hand Signals - Hand signals for turning and stopping are as
follows: Left arm straight out to signal a left turn. Left arm out and
down with you palm to the rear to signal slowing or stopping. And, for
a right turn, put your right arm straight out (in areas where this is
legal) or put your left arm out and bent up.
* Verbal Warnings - Along with hand signals, verbally warn
cyclists behind you of your changes in direction or speed. The lead
rider should call out "left turn," "right turn," "slowing," stopping,"
etc. Announce a turn well in advance of the intersection, so that
members of the group have time to position themselves properly.
* Announce Hazards - When riding in a tight group, most of the
cyclists do not have a good view of the road surface ahead, so it is
important to announce holes, gravel, grates, and other hazards.
Indicate road hazards by pointing down to the left or right, and by
shouting "hole," "bump," etc., where required for safety. Everyone in
a group should be made aware of hazards. However, not everyone needs
to announce them.

Ride with Safety and Courtesy as your guide

* Watch For Traffic Coming From The Rear - Since those in front
cannot see traffic approaching from the rear, it is the responsibility
of the riders in back to inform the others by saying "Car back". This
warns leading riders to maintain position and the potential of a
passing car. Use discretion on the car back warning: on busy roads
with continuous passing traffic, the call out of car back tends to
lose it's significance. Use the warning "Car up" on narrow road to
warn following riders of approaching traffic.
* Leave A Gap for Cars - When riding up hills or on narrow roads
where you are impeding faster traffic, leave a gap for cars between
every three or four bicycles. This way motorist can take advantage of
shorter passing intervals and eventually move piecemeal around the
entire group.
* Wait At Turns - If the group becomes at all separated, even by a
few dozen meters, someone should wait at the turn until the next rider
arrives at the intersection, and so on until all riders have made the
turn.
* Move Off the Road When You Stop - Whether you are stopping
because of mechanical problems or to regroup with your companions,
move well off the road so you don't interfere with traffic. It is
usually best for the lead rider to pull forward in the stopping area
and for other riders to pull in behind the rider in front of them. As
a courtesy, during regroups the last cyclist in controls when the
group will restart.
* Riding Two Abreast - Ride single file or double file as
appropriate to the roadway and traffic conditions and where allowed by
law. Even where riding double is legal, set a good example and be an
ambassador for cycling. Courtesy dictates that you single up when cars
are trying to pass you if the lane is wide enough for them to safely
do so.
