You are driving a vehicle in a built-up area. Does the visible prohibition sign apply to passenger cars?

The B-33 speed limit sign showing 70 applies to passenger cars. In a built-up area, passenger cars are among the vehicles covered by this increased limit, unless a specific rule requires a lower speed.

§ 27 ust. 1 i 3 rozporządzenia w sprawie znaków i sygnałów drogowych
