Why should you have the traffic information switched on, when driving on the motorway?

The selected combination is correct because having traffic information switched on while driving on the motorway is essential for safety and awareness.

Option 1 is important as it provides warnings about motorists heading in the wrong direction, which can prevent potentially severe accidents. This aligns with the German traffic regulations emphasizing the importance of being informed and cautious.

Option 2 is also crucial since it offers updates on traffic jams, helping drivers make informed decisions about their routes. This is particularly significant on motorways where sudden stops can lead to rear-end collisions.

Option 3, however, is not correct in this context. Although staying informed is highly recommended, it is not legally required to have traffic information switched on while driving on the motorway.

Understanding these options helps ensure safer driving practices and encourages adherence to traffic regulations, which ultimately enhances road safety for everyone.
