Hello……….. At what time is a photoample actually the flash trigger in red “sharply switched” ?? Ingendwo I heard that there is a guideline, after which the photo trigger can take place only after 2sec when crossing a redample. Keywords: Simple red light violation, qualified red light violation. Everyone knows the problem. One drives towards a cross. It is a flash lamp. One has first still “green”. Then the traffic light switches. Normalerw If it is a well-known photoample you don’t want to risk anything, so full braking, you have ABS. Especially tricky it becomes when you see in the rear-view mirror that the “backman” is too close. Do you really have to decide between a driving accident which you probably would not be responsible for, and a criminal case if you don’t brake? Is in this case a full braking really necessary or exist a few seconds reserve after the U.S. “Red”? Greetings……….
