Before driving any vehicle unsupervised, what must a driver demonstrate to the Motor Carriers?

A driver must demonstrate the capability of safely operating each different type of vehicle before they are allowed to drive any vehicle unsupervised. This requirement is critical because different vehicle types, such as a school bus, may have unique handling characteristics, dimensions, and safety features. Mastery of operational skills ensures that the driver can manage the vehicle under various conditions, which is essential for the safety of all occupants, especially children in the case of school buses.

While knowledge of traffic regulations, experience, and safety training are also important, they do not specifically address the practical skills required to handle each unique vehicle safely. Capability focuses on the driver's ability to operate the specific vehicle they intend to drive, which is a necessary prerequisite for unsupervised driving and is a cornerstone of ensuring safety on the roads.
