I know this question has come up before and someone looked up some local laws. In most states it seemed that if you're in a car you need to do the left-arm bent at a 90, otherwise noone will see your right arm signals. Cyclists can use either their right arm to point right or their left arm to do the angle. I find that motorists are confused when I hold up my left arm, so now I always point with the right for right-hand turns.Originally Posted by fatbottomedgurl
