You want to make a telephone call while driving. What must you be aware of?

Your selected combination is correct because it adheres to German traffic regulations regarding the use of mobile phones while driving. According to these regulations, you must use a hands-free unit when driving to ensure that your attention remains on the road. Additionally, if your vehicle is parked in a suitable location and the engine is completely turned off, you are allowed to use your phone without a hands-free system.

However, using a phone while the vehicle is moving, even at walking pace, is not permitted if you're not utilizing a hands-free device. This is to prevent distractions and maintain road safety. Understanding these rules helps ensure that you are responsible and compliant while driving.
