What do traffic signals mean? We explain what traffic signals mean, what their different colors mean, and go through how they work.
A traffic signal is a light or sound signal that regulates traffic. The different positions of the signal tell road users how to behave in traffic. Traffic signals contribute to safer vehicle traffic but also to the protection of pedestrians. Traffic signals use three different colors to show road users what applies.Red light: Stop the car until the light turns green. Yellow light: Slowing down, it's about to turn red. Treat yellow light as the beginning of a red candle instead of the end of a green candle. Flashing yellow light: Slow down and be extra careful. Green light: Drive through the traffic light. In the event that the traffic light is out of order, you should drive carefully and carefully. If the traffic light is out of order, other instructions apply, such as the obligation to give way or stop sign. If there are no such at the site, the right-hand rule applies. Traffic signals work by registering cars through sensors in the asphalt. These work according to the principle of induction, i.e. they detect if a metal object passes over them. Pedestrians need to announce themselves at the touch of a button. More sophisticated traffic signals consist of networks consisting of several intersections with traffic signals, with the goal of optimizing the flow of traffic or reducing emissions.
