What should you note when using your navigation system?

Your selection of answers is correct.

1. Considering vehicle dimensions on the proposed route is essential to ensure that the vehicle can safely navigate through narrow roads, low bridges, and other potential obstacles. This aspect is emphasized in German traffic law, which mandates that drivers must be aware of their vehicle's size to avoid accidents or traffic disruptions.

2. The rule regarding mounted mobile navigation systems not impeding the forward view is crucial for safe driving. When a navigation device obstructs the driver's line of sight, it can lead to distracted driving and increase the risk of accidents. German traffic regulations require that all equipment in the vehicle must not compromise safety.

The addition of the third option, which pertains to the calculation of arrival time and mandatory driving and rest periods, is also important as it ensures that drivers plan their journeys while remaining compliant with work and rest regulations, promoting road safety and preventing fatigue.

Understanding all components of navigation usage aids in safer driving and compliance with traffic regulations.
