The procedure could be initiated when double waved yellow flags were needed on any section of a circuit where competitors and officials were in danger, but the circumstances did not warrant deployment of the actual safety car.
O procedemento poderá iniciarse cando ondeen as dobres bandeiras amarelas en calquera sección dun circuíto no que os competidores e os comisarios poidan estar en perigo, pero as circunstancias non sexan tan perigosas como para xustificar a saída do coche de seguridade real.
