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

In the video you are driving on a roadway of a dual carriageway in a city, between noise barriers; on both sides of the roadway there are signs B-33 "speed limit" of 70 km/h. You are driving in a built-up area, and the visible prohibition sign applies to motorcycles. The answer is: yes.

The Regulation on road signs and signals states that sign B-33 placed in a built-up area and showing a permitted speed higher than 50 km/h applies to a passenger car, a motorcycle and a lorry with a maximum permissible mass of up to 3.5 t - with a few exceptions, among them a motorcycle carrying a child aged up to 7 and a vehicle towing a power-driven vehicle. A rider riding alone or with an adult passenger may therefore ride at 70 km/h on this section, just like the driver of a passenger car. A motorcycle is listed in the rule next to a passenger car, which is why the sign applies to it. A two-wheeler is, however, less stable and less visible, so at a higher speed the rider keeps a longer following distance and watches out for cars changing lanes.

Legal basis: § 27 para. 1 and 3 of the Regulation on road signs and signals; Art. 20 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
