You are driving a vehicle combination comprising a motor vehicle and trailer, and you want to enter a road that has this signpost. What does the reference to “5.5 t” mean?

This traffic sign indicates a weight restriction of 5.5 tonnes. According to German traffic rules, this limit applies to the actual mass of each individual vehicle in the vehicle combination, not the combined total mass or just the towing vehicle's maximum authorised mass. This means that both the motor vehicle and the trailer must weigh no more than 5.5 tonnes individually to be allowed on this road. This rule helps protect road infrastructure and ensure safety by restricting heavier vehicles from entering certain areas.
