Hello, thank God nothing happened, but I already got into the same situation twice. And there would have been an accident almost in both times. The following situation today at about 4 pm in a locality. In front of my polo a vehicle drives. We turn into a roundabout, first the front man and then me. We both turn into the same road. In this road is 50 km/h. This road is quite long, about 1km. Although 50km/h are allowed and the vehicle In front of me is a local (same local character) the front man drives about 300m long only 30 km/h. I am not in a hurry, but it is already deprecating after someone where you could drive really 50 after all. So, after about 300m I set turn signals to overtake. The road is straight and there is no oncoming traffic. When both vehicles are at the same height, the overtaking suddenly sets the turn signal and pulls to the left. In a courtyard entrance. The turn signaler becomes about 1 sec . placed before turning. I move on the curb where fortunately no one is. This curb is lowered. Let’s assume that it would have crashed, what does the question of guilt look like. If possible I would like to have firm facts and not just opinions.
