Can the person riding the bicycle overtake the slowly-moving vehicles on their right?

In the photo, you are driving along a wide city street behind a silver estate car, and to the left of it, on the boundary between the lanes, a cyclist in an orange jacket is riding; the traffic lights are showing green. The question is whether a cyclist may overtake slowly moving cars on their right side, for example in a traffic jam. The Road Traffic Act clearly allows this - it is one of the few exceptions to the rule that you overtake on the left. The answer is: yes.

The Road Traffic Act states that a cyclist may overtake slowly moving vehicles other than bicycles on their right side. This refers to situations when cars are crawling in a traffic jam and the cyclist has room between them and the kerb. For you as a driver, this means that before turning right and before opening the door you must glance in the right mirror and over your shoulder - a bicycle may come up on your right exactly when you are stationary or rolling slowly.

Legal basis: Art. 24 para. 12 of the Road Traffic Act (Prawo o ruchu drogowym)
