What does "use without authority" imply in terms of vehicle operation?

"Use without authority" specifically refers to the operation of a vehicle that is not owned by the driver and is done without obtaining permission from the rightful owner or person authorized to grant access. In this context, it implies that the individual has taken the vehicle unlawfully or without consent, which is a significant legal concern. This concept encompasses actions like borrowing a friend's car without asking or using a vehicle that is parked in a public space without the owner's permission.

The other options do not encapsulate this legal definition. Driving a car with a valid license is completely permissible and does not denote any unauthorized use. Operating a vehicle during restricted hours does not inherently imply lacking authority, as it focuses on timing restrictions rather than ownership consent. Similarly, taking a vehicle for a test drive typically involves receiving explicit authorization from a dealership or car owner, thus not falling under the definition of "use without authority."
