Correct answer
C. 4 m.
Explanation
In the photo, a lorry with a load box covered by a tarpaulin, loaded above the sides. The maximum permissible height of a lorry with its load is 4 m - answer C.
The Road Traffic Act states directly that the height of a vehicle with its load must not exceed 4 m. This limit comes from the clearances on roads - the clearance gauge under flyovers, in tunnels and under the overhead contact line is designed with a margin above 4 m, so a vehicle up to 4 m high will fit on public routes, as long as there is no sign B-16 with a lower value. The answer 3.5 m is too low, and 4.5 m is already an abnormal (oversize) vehicle, which requires a permit and must travel along a designated route. You always measure the height from the ground to the highest point of the load, not of the vehicle alone - this is also what sign B-16 "no entry for vehicles higher than ... m" is about, as it applies to the vehicle together with its load. Before loading, it is worth writing down the height of the combination in the cab.
Legal basis: Art. 61 para. 10 of the Road Traffic Act (Prawo o ruchu drogowym); § 20 para. 2 of the Regulation on road signs and signals
