Understanding the interplay between technology and traffic law is crucial for every driver in Germany. This guide clarifies how to correctly use navigation devices and smartphones to avoid potential fines and penalty points in Flensburg, ensuring you stay compliant with §23 StVO while navigating safely.

Article content overview
German traffic law under §23 Abs. 1a StVO strictly prohibits holding electronic devices while driving, with a €100 fine and 1 point penalty for violations even at traffic lights. Navigation devices must be securely mounted without obstructing the driver's field of vision, and voice control is the recommended operating method. Speed camera warning apps are legal in Germany but must be set before driving—touching them while in motion is prohibited. Manual device interaction, such as entering a destination, requires the vehicle to be at a complete standstill with the engine switched off. Understanding these distinctions is essential for both passing the theory exam and maintaining a clean licence in Flensburg.
