Does this sign inform you of the minimum speed at which you are allowed to travel?

In the video you are driving along a street in a city centre, you pass a bus and on the right you see a white square sign with a red circle and the number 30 - this is sign B-43 "speed limit zone" - and below it sign B-36 with plate T-24 about towing away. Sign B-43 does not inform you of the minimum speed, but of the maximum speed allowed in the whole zone. The answer is: no.

The Regulation on road signs and signals states that sign B-43 "speed limit zone" marks the entry to a zone in which you must not exceed the speed shown on the sign as a number of kilometres per hour, and a sign showing a speed of 30 km/h or less also means that speed bumps and other devices that force slow driving might not be marked with warning signs. The minimum speed is set by a completely different sign - the blue round sign C-14 with a white number. The limit from sign B-43 applies on all streets in the zone until sign B-44 "end of speed limit zone", and not only up to the nearest junction, as with the ordinary B-33. In such a zone you drive at no more than 30 km/h and expect speed bumps, traffic islands and pedestrians in narrow streets.
