You need assistance on the autobahn. Which information does the arrow on the roadside marker give you?

You answered correctly. On the autobahn, the arrow on the roadside marker points in the direction of the nearest emergency telephone. If you need assistance, follow the direction of the arrow to find the emergency call phone. This helps drivers quickly get help in case of breakdowns or accidents. It does not indicate the direction of the next exit or car park—only the emergency telephone. Knowing this can help you act quickly and safely in an emergency.
