How is 'standing' defined in traffic regulations?

In traffic regulations, 'standing' refers specifically to the act of halting a vehicle for purposes other than picking up or dropping off passengers. This definition is crucial for enforcing traffic laws, particularly in areas where parking regulations are in effect. When a vehicle is standing, it is not necessarily parked in the traditional sense but is instead halted for reasons that may impede the flow of traffic or violate designated no-standing zones.

Understanding this definition helps police and other law enforcement officials identify instances where a vehicle may be obstructing traffic, thus ensuring smooth and safe roadway conditions. The context surrounding the other options highlights various aspects of vehicle use; however, they do not encapsulate the precise legal definition of 'standing' as established in traffic regulations.
