Correct answer
No; this sign alone does not prohibit this semi-trailer combination.
No. R-112 restricts motor vehicles towing trailers covered by this prohibition, with an exception for single-axle trailers; DGT guidance also distinguishes semi-trailers from the trailers it restricts. It therefore does not by itself bar the tractor unit and semi-trailer in this question. For a trailer covered by it, the figure restricts entry when its maximum authorised mass exceeds 2 tonnes, rather than 3,500 kg or the actual cargo mass. Other restrictions may still apply.
