When a disabled person or someone with visibly reduced mobility enters a pedestrian crossing with a special sign, should you anticipate having to stop your vehicle?

Yes, in this situation you are obliged to allow a person with a disability or obviously limited mobility to cross. According to the regulations, the driver is then required to stop the vehicle to enable them to cross the roadway safely. This is directly regulated by Art. 26 para. 7 of the Road Traffic Act.
