You want to park in a car park where there is a parking-ticket machine. What must you remember?

The selected combination is correct because both points emphasize essential aspects of using a parking-ticket machine in Germany.

1. Placing a valid parking ticket in your vehicle ensures that parking wardens can easily verify that you have paid for parking, preventing potential fines.

2. Not exceeding the parking time indicated on the parking ticket is crucial, as doing so can lead to penalties or fines. This rule helps keep parking spaces available for others and contributes to the orderly management of public parking areas.

The option about using a parking disc is not applicable in this case because a parking disc is typically used in areas where parking is regulated by time limits rather than requiring a paid ticket. Understanding these rules is important to avoid illegal parking and the subsequent penalties.
