At what maximum distance may the “Intersection Area” traffic sign be installed at a complex intersection if it cannot be installed at the boundary of the intersection?

Explanation

Sign 1.35 "Intersection area" is placed at the boundary of the intersection. If at a complex intersection it cannot be put there, it is placed no more than 30 m from the intersection boundary. 10 m and 20 m are not what the Rules say (Rules, sign 1.35).
