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?

You answered correctly. This traffic sign sets a limit for the **actual mass of each individual vehicle** in your vehicle combination. That means neither your towing vehicle nor your trailer can exceed 5.5 tons each, regardless of their combined weight. The rule ensures that no single vehicle crossing that point is heavier than the indicated value. Always check the actual (current loaded) weight, not the permissible maximum or the total combination weight, before entering such roads. This helps protect road surfaces and bridges.
