What is the term used for the record of all vehicles each driver can operate unsupervised?

The term "Driving Proficiency" refers to the record that indicates the vehicles a licensed driver is competent to operate without supervision. This encompasses an individual's skill level and familiarity with various vehicle types, ensuring they meet the necessary requirements and standards set by the licensing authority.

In the context of driving and vehicle operation, proficiency indicates a driver's ability to handle specific vehicles safely and competently. This is essential for establishing the driver's qualifications for operating different classes of vehicles, such as passenger cars, trucks, or motorcycles, without needing additional oversight.

The other choices might seem relevant but do not encapsulate the concept as precisely as "Driving Proficiency." For instance, while "Drivers Records" could refer to a broader array of documentation, it doesn't specifically denote the scope of unsupervised vehicle operation. Similarly, "Drivers Logbook" typically pertains to a record-keeping document used by commercial drivers for hours of service or routes driven, rather than an official record of vehicle proficiency. "Drivers Proficiency Records" could also imply a record but is less commonly used in terminology and lacks the definitive essence captured by "Driving Proficiency."
