Today it was so far again. Left lane closed because of a construction site, and huge signs to use the zipper procedure. So the lane hold to the obstacle and then first to the right. But 500 m before the obstacle the traffic crawling in front of me had already squeezed to the right into the column. Before me on 500 m no car on my lane. As prescribed I remained on the left lane to drive at about 30 km/h to the obstacle. 0 m in front of the obstacle suddenly shimmers out of the standing right column a car on my lane, stops obliquely in front of me, and forces me to complete a braking. While I still think what a nut, and he happily waving his middle finger to the horror, two police officers, who drove two cars behind me, came and gave the nice gentleman an ad for coercion, road traffic danger and insult. He nevertheless had no insight, he had never heard of the mandatory zippering procedure. He now hears something from the office. The end of the game. A beautiful backlog on both lanes. Do you also sometimes pass that many do not know the new traffic rules, and want to slow down correctly driving road users? Gruss, Günther.
