Final answer:
In the legal context, 'operating' a motor vehicle encompasses not just driving on public roads but also the potential to control the vehicle's functions. It's important for legal definitions to be valid and reliable, much like in research operational definitions.
Step-by-step explanation:
The definition of "operating" a motor vehicle in regards to the law refers to the control and management of a vehicle, which includes not only driving the vehicle on a public road but also being in a position to start the engine, or manipulate the mechanical or electrical equipment of the vehicle. Operating a vehicle is a term often used in legal contexts, especially when determining whether someone was in control of a vehicle during the commission of a traffic violation or crime. The concept of an operational definition, as it applies to law, must be both valid and reliable to ensure consistent application across different cases. For instance, an operational definition of a "good driver" might include objective measures such as "a driver who has never received a traffic violation", which provides a specific and measurable criterion.
