Parking (not stopping) in dangerous places or places that seriously obstruct traffic is considered to include situations that constitute a risk or obstacle to traffic, such as when parking is carried out in a double row without a driver. You may not stop or park at pedestrian crossings, but you may do so in their vicinity. In loading and unloading zones, parking is prohibited during their hours of use but not outside those hours.
