I've been riding by myself for almost a year now but i have no idea how to ride in groups. One of my friends just bought a new bike and i don't know whether we should split lanes or not? We usually run staggered formation but at a red light should we be splitting or sharing the same lanes? Also, at a stop making turns who is supposed to go first? when making a left does the person on the left turn first? and for making a right, does the person on the right turn first? and what hand signals do you use while riding together?
