Whether riding in a group or riding alone, hand signals are important to your overall safety. Motorcycle safety using hand signaling lets the other people around you know what you are doing. Hand signals greatly increase your visibilty. When riding in groups, hand signals are really important because of the limited visiblity of the riders behind you. When riding in a group, the person behind you likely doesn't know what is going on ahead of you. The courteous rider will relay signals back through the pack.
