Rule 808.4c
Official source text from the 23 April 2010 Rules release
When a player ends his or her turn, that player passes the turn marker to the player on his or her left. A player can't receive a turn marker if any player in the three seats to his or her left has a turn marker. If this is the case, wait until the player four seats to his or her left takes the other turn marker.
