text: Hand signals are given by cyclists and some motorists to indicate their intentions to other traffic. Under the Vienna Convention on Traffic, bicycles are considered vehicles and cyclists are considered drivers, a naming convention reflected in most traffic codes.
  In some countries, hand signals can apply to any vehicle whose signal lights are missing or damaged. This rule also applies to drivers of small motorized vehicles such as mopeds and motorcycles.
  Like car drivers, cyclists use three primary signals:
  Left turn/ overtaking
  Right turn
  Stopping/ braking.
  Left turn
  All countries
  To signal a left turn, the driver horizontally extends their left arm outwards.

  The driver extends their right arm with the forearm pointing vertically downwards and moving in a circular anti-clockwise motion. Drivers of tractors, animal-drawn vehicles and two-wheeled vehicles may also extend their left arm horizontally with the palm facing forwards. Signal lights or turn indicators may be used in place of hand signals if installed.
