All the traffic lights are showing red, only on little arrow is blinking yellow. Can I turn left? Yes. This type of traffic light is a speciality of France (or at least of Languedoc), and you can find one in Nîmes, too.
Highway A9, Lyon and Marseille to one direction, Barcelona to the other.
(Seen from a car window, returning from the suburb’s of Nîmes to the city center.)
