Yellow Circles Appear on European Roads to Caution Drivers

Yellow circles have been appearing on roads in several European cities, including Düsseldorf, Berlin, and Karlsruhe in Germany, as well as in Austria. These markings are designed to increase road safety by making drivers more cautious without installing additional signs or imposing new restrictions. The yellow color, which contrasts with the dark asphalt, is intended to draw drivers' attention to the road surface and encourage them to reduce their speed. The circles aim to reduce speed, increase driver alertness, and decrease traffic intensity. Some places also use these markings in combination with road barriers to improve safety for cyclists and pedestrians. While there are opponents who argue that these markings could confuse drivers due to lack of awareness, early results show a decrease in traffic speed.
