When can vehicles cross a special reserved crossing?

Crossing a special reserved crossing is permitted primarily for specific practical circumstances, such as needing to park or exit a property. This rule is in place to ensure that vehicles can navigate safely and efficiently while allowing for the movement of public transport, particularly trams and buses, which rely on these crossings for their routes.

When a driver is leaving a property or needs to park, that situation might necessitate crossing the reserved area, as long as it can be done safely and without obstructing the flow of public transport. The design of roadway regulations emphasizes the need for clear pathways for public transportation, hence why other vehicles crossing these areas is restricted primarily to necessary maneuvers like parking or exiting private properties.

The other options either imply restricted crossing conditions that do not align with the intrinsic purpose of a special reserved crossing or suggest scenarios where crossing could disrupt the efficiency and safety of the transportation system.
