If you are new to cycling, especially cycling with a group, here are some rules to remember (copied from League of American Bicyclists).

1. Be predictable
   • In a group, your actions affect those around you, not just yourself.
   • Riders expect you to continue straight and at a constant speed.
   • Signal your intention to turn or slow down before you do so.
2. Use signals
   • Use hand signals to indicate turns and point out hazards to others.
   • Left or right arm straight out to indicate left or right turn.
   • Left arm out and down with palm to the rear to indicate stopping.
3. Give warnings
   • Ride leaders should call out right turns, left turns and stops in addition to signaling.
   • Announce turns before the intersections to give riders a chance to position themselves.
   • Try to avoid sudden stops or turns except for emergencies.
4. Change positions correctly
   • Slower moving traffic stays to the right; faster traffic to the left.
   • Pass slower moving vehicles on the left; announce your intention to do so.
   • Announce passes on the right clearly as this is not a usual maneuver.
5. Announce hazards
   • Most cyclists do not have a full view of the road while riding in a group.
   • Announce potholes and other hazards so others can avoid them.
   • Call out the hazard and point down to it, either left or right.
6. Watch for traffic from the rear
   • The last rider should frequently check for overtaking cars.
   • Announce "car back" clearly and loudly.
   • It is also helpful to announce "car up" on narrow roads or when riding two abreast.
7. Watch out at intersections
   • Leader should announce slowing or stopping at intersections if necessary.
   • Cyclists should not follow others through intersections without scanning.
   • Each cyclist is responsible for checking cross traffic; if you must stop, signal.
8. Leave room for cars
   • On narrow road or during climbs, leave space between every three or four riders.
   • Motorists will utilize the shorter passing intervals to pass the group.
   • Good relations with motorists is the responsibility of every cyclist.
9. Stop off road
   • When stopping for mechanicals or regrouping, always move clear off the road.
   • Only if conditions permit should you move back onto the road as a group.
   • Always yield to traffic in the roadway.
10. Ride single file
    • It is illegal in some areas to ride more than two abreast.
    • Ride single file between intersections; double up when the group stops.
    • When taking the lane, double up and take the whole lane.
