Which of the following is a legal parking distance from a roadside?

The distance of 0.5 meters from the roadside is recognized as a legal parking distance in various regulations related to parking in many jurisdictions, including those that might apply under the Okinawa Status of Forces Agreement (SOFA). This minimal distance helps ensure that vehicles do not obstruct pedestrian movement or create hazards on the road.

In contrast, while different locations may have specific regulations that vary, the common requirement of a half-meter distance balances safety and accessibility around parked vehicles. It provides enough space for pedestrians to pass and for vehicles to maneuver safely, supporting the overall structure of effective traffic management.

The other options typically exceed the commonly accepted legal distance for parking situations, leading to possible violations of traffic regulations depending on the local laws in place. Understanding these requirements is crucial for maintaining compliance with the legal standards governing parking behavior in the area relevant to SOFA.
