Up to which permissible total mass may motor vehicles be parked on specially designated footpaths?

You answered correctly. In Germany, parking motor vehicles on specially designated footpaths is only allowed if the total weight of the vehicle does not exceed 2.8 tons. This regulation ensures that only lighter vehicles, such as most passenger cars, can use these marked footpath parking areas, protecting the pavement and ensuring pedestrian safety. Heavier vehicles are not permitted, as they could damage the footpath or create hazards for pedestrians. Always check for signs or markers indicating special footpath parking and observe the weight limit of 2.8 tons to comply with the rule.
