What is the maximum number of hours a day you are allowed to drive a truck and trailer with a permissible total mass of 24 t?

According to German and EU driving regulations for professional truck drivers, the maximum daily driving time for a truck and trailer combination is 9 hours. However, the law allows you to extend this driving time to 10 hours on no more than two days per week. This rule is designed to prevent driver fatigue and ensure road safety. You correctly selected the answer that matches this regulation. Remember: never exceed 9 hours per day except for two days in a week, when 10 hours is permitted. The rule does not allow for 10 hours every day or 10 hours on three days per week.
