The mystery of the yellow circles on the roads has been solved! It's not a ban, see what it does.

In some European cities, yellow circles drawn on asphalt are attracting attention with a look that differs from conventional traffic signs. This method, employed in the German cities of Düsseldorf, Berlin and Karlsruhe and in parts of Austria, aims to slow drivers down.

In an approach based on traffic psychology, visual markings on the road are used instead of setting new speed limits or installing additional traffic signs. By leveraging the eye‑catching effect of yellow, the goal is for drivers to become more aware of their surroundings and to control their vehicle speeds.

Drivers' Speed Reduction Is Targeted

Yellow circles that stand out clearly on dark‑colored asphalt aim to direct drivers' attention to the road. Drivers who see the markings are expected to reassess their speeds and, if necessary, pull their feet off the accelerator.

In particular, making traffic flow more controlled in residential areas and encouraging drivers to behave more cautiously toward other vehicles and road users is the goal. This is intended to contribute to reducing the risk of accidents.

Not an Official Traffic Sign

The yellow circles on the roads are not part of standard traffic signs. These markings, by themselves, do not introduce a new speed limit nor do they create a new traffic prohibition for drivers.

Therefore, drivers who see the yellow circles should not interpret them as a direct prohibition sign. The app’s primary goal is to influence driver behavior through visual warnings and foster a more cautious driving habit on the road.
