On a road designated in this manner, does a person using a mobility aid have the right to use the full width of the road and have priority over vehicles?

Why?

Sign D-40 marks the entrance to a residential zone. Someone using a non-motorised movement aid, such as roller skates, may use the full width of the road here and has priority over vehicles. This entitlement comes from the special rules that apply within the zone.
