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

Answers 1 and 2 are correct because in Germany you may only use a phone while driving if you do not hold it in your hand and you do not get distracted from traffic.

Rule of thumb: “Hands on the wheel, eyes on the road, mind on driving.” A phone call is only allowed if the device is operated hands-free or via a fixed holder and you can use it with a brief glance or minimal operation (for example, one short tap). If you have to pick it up, hold it to your ear, type, scroll, search a contact for a long time, or look at the screen repeatedly, it counts as prohibited phone use because it distracts you.

Answer 3 (“not longer than 7 seconds”) is not a valid rule. German law does not allow a fixed “7‑second limit.” Even a shorter use can be illegal if you hold the phone or if it distracts you; and even hands-free use becomes a problem if it leads to inattention (e.g., complex interaction with the device).

To solve similar questions: the key test is whether you are holding the phone or manipulating it in a way that takes your attention away from driving. If yes, don’t do it; pull over safely first.
