This is a dashcam video from Polish TV of an accident similar to my mysterious accident last year. The driver gets a green arrow (upper left corner almost immediately at start), makes a left turn at an intersection, and is hit by a truck that either runs the associated stop lights to his right or also gets a green light. This is in broad daylight and the stop lights should be easily visible to the other driver.
This is the full story from Polish TV:

I would be curious to get a translation of the story and comments.
