Upon an amber flashing signal of the traffic lights, non-working traffic lights and absence of the authorized official directing traffic, the intersection is unregulated, and drivers are obliged to follow the rules of driving in unregulated intersections and priority road signs. Traffic lights are deemed to be non-working if there are no signals on all traffic lights for a given direction or the signals are contradictory.
Upon a turned-on arrow of an additional section of the traffic lights (simultaneously with prohibitory signal), the driver located on the outer lane of the carriageway must keep on moving in the direction of this arrow, if his stop can create an obstruction for movement of vehicles following him on the same lane, unless another order of road traffic for vehicles is determined by road signs “Directions of movement on the lanes”, “Direction of movement on the lane” or relevant horizontal road marking.
