Why is it illegal to drive with a Nevada instructor permit alone?

This is all I could find, hope it helps.

No driving alone. You must have a supervising driver accompany you at all times while you practice your driving skills. The supervising driver must be seated in the front seat next to you and be prepared to take control of the vehicle at any time. The supervising driver has to be at least 21 years old and have not less than one year of driving experience.

"quid pro quo" harassment takes place when a supervisor requires sex, sexual favors, or sexual contact from an employee/job candidate as a condition of their employment. only supervisors who have the authority to make tangible employment actions (i.e. hire, fire, promote, can commit "quid pro quo" harassment.
