Red cross on the traffic light. What does it mean for drivers?

The red cross symbol on black background, found on traffic lights in some European countries, aids drivers in safely turning left. When illuminated, it indicates that oncoming vehicles have a red light, allowing drivers to assess safe turning conditions. This symbol is primarily used in France, Switzerland, and Belgium, and also in Quebec, Canada, but is losing popularity due to efforts for uniform traffic signals. In Poland, the standard traffic lights do not feature the red cross, but an S-4 signal indicates a strict no-entry for certain lanes. Left turns at green lights require yielding to oncoming traffic and pedestrians, while green directional arrows provide safer turning options.
