You want to use a navigation device mounted on your motorcycle. What should you observe?

You answered correctly by choosing all three options. When using a navigation device on a motorcycle, German traffic rules require that you only enter destinations when the vehicle is stationary to avoid distraction. Operating the device while driving should be avoided whenever possible because it diverts your attention from the road, increasing the risk of accidents. Using the voice output function through your headset is recommended because it allows you to receive directions without needing to look at or touch the device, keeping your focus on driving. Following these rules helps ensure your safety and the safety of others on the road.
