Overview
- The StVO (Anlage 3) explicitly says drivers must signal with the direction indicators when they follow the curve of a priority road because following the curve counts as a change of direction.
- Media reports on October 22, 2026 reiterated the rule and explained that driving straight to leave the priority road does not require a signal, while following the curved priority road does.
- Studies and club observations show large-scale confusion: a Dekra/ADAC study found only about half to two thirds of drivers signal correctly and the Autoclub ACE recorded 24.7% incorrect signaling when exiting roundabouts.
- Failing to signal carries fines under the Bußgeldkatalog starting at €10 for a missing indicator and rising up to €100 plus one point in Flensburg if other road users are endangered.
- The sign for an abknickende Vorfahrt is the yellow-white diamond with a supplemental plate showing the route of the priority road, and clearer public education could cut near-miss risks for cyclists and pedestrians.
