Unlock Combination weight

May I couple this trailer on?

Highest legal combination weight for lorry + trailer: the lowest of the legal table by number of axles (§ 21), the sum of the registered weights and a registered combination weight (§ 30). Also checks the 1.5 rule for the trailer and the requirement of 20 % of the weight on the driving wheels (§ 23) and shows the axle spacing requirements. Cited from BEK 1447/2025.
