text: US and Canada There are two methods for signaling a right turn. The first, more commonly known signal is to extend the left upper arm out to the left, horizontally, and angle one's forearm vertically upward. The second method is to extend the right arm perpendicular to the body, pointing in the same direction as the intended turn. Some states do not recognize the right arm because drivers are taught to only look at the bicyclist’s left arm for all signals, but most states allow the use of either arm.
  The Uniform Vehicle Code in the US recognizes both signals. State traffic laws generally conform to the Uniform Vehicle Code, but exceptions may exist. Both signals are recognized in British Columbia, Canada.

  The driver extends their right arm horizontally with the palm to the front. If a vehicle is fitted with turn indicators, they may be used instead.
  This signal has the advantage of being more visible to affected traffic, specifically vehicles in the next lane to the right. It is also more easily understood by children.
  Overtaking
  In right-hand traffic countries, the left turn-hand signal is used to before normal overtaking to the left.
  Correspondingly, in left-hand traffic countries, a right-hand signal is used before normal overtaking on the right.
  South Africa
  A vehicle may signal a vehicle behind them to overtake them by extending the right arm below shoulder level, with the palm facing forwards, and moving the arms backwards and forwards.
