You are driving a single-track motorcycle. Are you allowed in this situation to drive onto the bridge?

In the photo, in the rain, you are approaching a cobbled bridge; on the right there is a round sign with a red border and the figure of a car - B-3 "no entry for power-driven vehicles, except single-track motorcycles". When riding a single-track motorcycle, you may drive onto the bridge. The answer is: yes.

The Regulation on road signs and signals states that sign B-3 "no entry for power-driven vehicles, except single-track motorcycles" means no traffic of power-driven vehicles, but the ban does not apply to single-track motorcycles. The exception is written into the name of the sign itself: cars, lorries, buses and motorcycles with a sidecar cannot enter, but an ordinary two-wheeled motorcycle can. Such signs are placed on old, narrow bridges and roads whose load capacity or width does not allow traffic of wider vehicles. Do not confuse B-3 with sign B-1 "no vehicles in both directions" (an empty white circle with a red border), which applies to all vehicles, or with B-4 "no entry for motorcycles". On wet cobbles you ride a motorcycle carefully: paving stones are very slippery in the rain, and there are pedestrians with umbrellas walking on the bridge.

Legal basis: § 18 para. 1 of the Regulation on road signs and signals; Art. 2 point 45 of the Road Traffic Act (Prawo o ruchu drogowym)
