Does the visible sign presented in this situation indicate a traffic prohibition for vehicles, which their height (including load) exceeds 3.1 metres?

Why?

The B-16 sign showing 3.1 m prohibits entry by vehicles taller than 3.1 metres. The measurement includes the vehicle's full height with its load, including anything carried on the roof.
