Why this is the answer
The correct answer in the official bank: No, unless there is a signpost indicating otherwise.
It is prohibited to park a vehicle beside a pedestrian safety guardrail, unless a sign has been placed that indicates otherwise. This is the rule, and only a sign can change it. So it makes no difference whether the parking is short or whether there are no pedestrians beside the guardrail.
