At the spot marked by the visible sign, are you required to yield to someone using a mobility aid who is crossing at a cycling crossing?

Why?

Sign D-6b marks a pedestrian crossing alongside a cycle crossing. You must give way to a person already on the cycle crossing using non-motorised equipment for getting around, such as roller skates. This duty applies to more than just cyclists.
