What is the maximum permissible time at the wheel per day when driving a truck with a permissible total mass of 16 t?

In Germany, the regulations regarding driving times for truck drivers are established to ensure safety and reduce fatigue. For a truck with a permissible total mass of 16 tons, the maximum driving time per day is typically up to 9 hours. However, it allows for extended driving times, up to 10 hours, up to two times a week.

This means that the correct combination of answers must indicate both the standard maximum driving time of 9 hours and the provision for the additional driving time of 10 hours on certain days, specifically twice a week.

Understanding these regulations is crucial for compliance and road safety, as they help prevent driver fatigue, which can lead to accidents. This is why it's important to consider all relevant aspects of the question.
