When passing through an intersection, drivers must follow the requirements of traffic signs.
Drivers must wait for a traffic light signal.✓Правильный ответ
Объяснение
The English option texts diverge from the source editions: the accepted source response requires waiting for a permissive traffic-light indication, not merely any signal. Red and yellow together still prohibit movement and only announce that green is about to appear, so starting immediately treats a warning as permission.
