Accidents happen all the time. The causes that produce such events are multiple. I think the main causes of traffic accidents are non-compliance with basic rules. The meaning of the red color of the traffic light is not respected, also non-compliance with the “Stop” traffic sign. Inattention and fatigue are other main causes in producing unwanted road events. Crossing the street through forbidden places, risky overruns and excessive speed completes the list of causes that cause accidents. At the top of the causes that cause accidents is speed. Something can be done when a complicated situation arises in traffic if the speed is not too high.
