One important, yet often overlooked, courtesy is the hand signal. Hand signals will tell the people you meet on the trail how many are in your group. The first rider in the group is responsible for sending the first signal to the on coming riders, or hikers, horsemen etc. The hand signal is accomplished by holding up the number of fingers representing the number of machines in the group. All members of the group should participate in sending the hand signals indicating the number of machines to follow. The message is completed by the last rider who indicates that they are the last rider by holding up a closed fist indicating that there will be no riders to follow.
Hand signals are particularly valuable when traversing very narrow trails. Riders coming down a trail should give right of way to riders going up the trail.
