At what speed is the bus driver allowed to continue driving past this prohibition sign?
Show the correct answer
Correct answer
C. 50 km/h when towing a trailer regardless of the GVM of the combination.
Explanation
In the photo you can see a road at the entrance to "Rzeszów": on the right there are built-up area signs, and a little further on, also on the right, sign B-33 limiting the speed to 70 km/h. The driver of a bus pulling a trailer may drive beyond this sign at no more than 50 km/h, no matter what the maximum permissible mass of the combination is - answer C.
The Regulation on road signs and signals states that sign B-33 showing a speed higher than 50 km/h, placed in a built-up area, applies only to a passenger car, a motorcycle and a lorry with a maximum permissible mass of up to 3.5 t. A bus is not on this list - with or without a trailer, the general limit of 50 km/h in a built-up area applies to it. That is why answer C is true, and answers A and B are wrong: a bus may not drive at 70 km/h either with a maximum permissible mass of up to 3.5 t or regardless of it, because the sign simply does not apply to it. The 50 km/h limit in a built-up area applies around the clock.
