When you ride a motorcycle with a side car, can you carry a passenger who has consumed alcohol?

In the photo there is a motorcycle with a sidecar on the right-hand side. When riding such a motorcycle, you may carry a passenger who has drunk alcohol (state after alcohol consumption) only in the sidecar - answer A.

The Road Traffic Act forbids carrying a person who is intoxicated, after drinking alcohol or after taking a substance with a similar effect on a bicycle, moped or motorcycle, unless the person is carried in a sidecar. The purpose of the provision is practical: a passenger on the back seat is part of the balance of the motorcycle - they must hold on, lean in bends and not make sudden movements, and a person under the influence of alcohol may fall asleep, lean out or fall off, bringing down the motorcycle with the rider. In a sidecar the passenger sits low, in a closed body, and does not affect the balance in this way, so the Act makes an exception. Answer B is directly forbidden, and answer C is too broad. Add common sense to this - even in a sidecar a drunk passenger without a fastened helmet, or one who jumps out while riding, is a danger, and every person carried on a motorcycle must wear a helmet.

Legal basis: Art. 45 para. 2 point 2 and Art. 40 para. 1 of the Road Traffic Act (Prawo o ruchu drogowym)
