Who has right of way in a riding arena?

Answer 1

you ride with the left hand facing the wall closest to you and the right hand into the areana and when you are asked or you want to change rein you ride in a little circle till youre right hand faces the wall.

That is factually incorrect. In the UK, you ride left to left but in France your ride right to right. when you are showjumping and warming up there is a red flag on the right which shows you which jump to go over.the correct direction

-------u pass left shoulder to left shoulder-the person going to the left has the right of way

Always pass on the right (follow this rules if you are going the same speed as the person you are passing and they are going the opposite direction as you), In every other scenario pass on the inside of the person that is going at a slower gait. It is always polite to tell the person you are passing by saying "Inside!" if you know the person's name add that to the end, if not say the horse color. Ex: "Inside Molly!" or "Inside Bay!" Obviously you shouldn't say this in the show ring as this might loose you some points.
