What vehicles - including with trailer - may be driven by someone even before their 18th birthday if they hold a Class T driving licence?

With a Class T driving licence in Germany, people are allowed to operate tractors and self-propelled agricultural machinery with a maximum speed of 40 km/h, including with a trailer, even before turning 18. The rules are stricter for higher speeds: only after reaching the age of 18 may a person drive vehicles up to 60 km/h in this licence class. Therefore, the correct answer is 40 km/h. This licence is mainly for agricultural or forestry tasks, not for general car or truck driving. Always remember: the speed limit matters for the age exemptions with Class T.
