You receive a telephone call while driving. What must you be aware of?

You answered this question correctly. In Germany, you are only allowed to use a phone while driving if it is not held in your hand, such as when you use a hands-free system. This is to ensure that both hands remain available for driving when necessary. Even a short glance at your phone can distract you from the road, so you must minimize your attention away from driving. The law does not permit phone use for a specific time like "7 seconds"—any use that takes your attention from the road can be dangerous and is not allowed. Always make sure your phone use while driving follows these rules to stay safe and avoid penalties.
